Comfortable weekend incoming and less thawing and more potential snowing next week

The heavy snow showers on Wednesday combined with the over-performance snow Tuesday evening has created some of the best skiing of the season and we finally can enjoy it without -20 to -40 degree wind chills. Still chilly for Friday, especially in the morning with temperatures not far from zero. Then the February sunshine goes to work and temperatures recover into the 20's with tolerable wind speeds to go along with some terrific visibility. 

Weekend weather has come better into focus this Thursday so we can drill into some finer details and stop speculating as to unlikely possibilities. Clouds and some snow showers appear likely for early Saturday and a dusting up to 2 inches is our expected outcome. Temperatures are expected to remain in the 20's with gusty yet manageable wind speeds. Those clouds should decrease as the day progresses leading to a colorful sunset and a chilly yet seasonable overnight. Sunday appears outstanding with some sunshine, less wind and temperatures recovering to the high 20's. The storm on Monday appears far enough south to keep its cloud shield away from northern Vermont though some warm advection cloudiness is possible as the day progresses. Readings of near 30 degrees Monday will make it feel almost balmy. 

I rather like the direction  next week appears to be headed right now. We've handed in our resignation on cold weather which is fine, but there are varying forms of mild weather and if it's the kind that produces temperatures near the freezing mark with snow falling, we'd certainly sign up for that. Storminess will get rather consolidated across the Rocky Mountain west early next week with much needed snowfall in the northern Rocky Mountains while arctic cold is bottled up over western Canada. MRG will have that aforementioned 30-degree day on President's Day Monday followed by what I think will be a milder day on Tuesday with readings testing the freezing mark. We haven't done that on the mountain since January 14th and if we do it with dry weather and low dewpoints, it will prove rather inconsequential. More cloudiness should then accompany another mild day on Wednesday as an organized storm system approaches. This system does not appear headed deep into Quebec. It's eventual track might actually end up south of Vermont with a push of colder Canadian air providing support for wintry precipitation. Some rainfall remains probable while the prospects for some substantial snowfall has gained some steam with this low level push of cold appearing more robust. Remember in these types of cold years, with ice covering the Great Lakes aggregate at about 50 percent, threatening thaws can suddenly become substantial snows. The time frame on this would be in the Wednesday/Thursday period  with weather conditions drying out for the last full weekend of February. 

It appears the EPO will hold steady in a slightly positive state for the rest of the month while the big feature will be a high latitude block expected to set up in the extreme northeast portion of the Eurasian continent. This will position cold in North America but mostly western North America while New England mostly stays out of the bitter chill. Late February does have a tendency to produce a mild day even in a general period of relatively seasonable weather so I would expect that in the last week of the month along with some sort of additional snowfall.  

Finally a weekend without extreme cold and wind

Our local NBC affiliate suggested that Lake Champlain was 99 percent frozen as of February 9th and I didn't visually spot any open water from the top of Stark Mountain on the early part of a bluebird Tuesday.  One easy way to calibrate the intensity of a cold year is to simply observe the amount of land mines a skier as to dodge at the bottom of Lower A at MRG. If there are none, such as now, Lake Champlain is probably close to or entirely frozen. Freezing the "Sixth Great Lake" is challenging because of its depth and significant since it eliminates a source of moisture that contributes to our seasonal snowfall. The additional snowfall we are expecting Wednesday and Wednesday night will in fact be held down because of the aforementioned ice. There are positive byproducts to freezing this local body of water however and this will come in handy next week when fending off the milder pushes of air that are currently being forecast. 

Tuesday night snowfall came in successfully and light snowfall on Wednesday and Wednesday night should add 1-3 inches to that total.  Temperatures might even get close to the freezing mark in valley locations though this is not expected on the mountain. Conditions are actually expected to turn blustery again by later Wednesday and continue into early Thursday with daytime temperatures closer to 20. We should get some clearing late on Thursday setting us up for a magnificent bluebird Friday with low wind speeds and temperatures recovering to 20 degrees from a morning low of zero.  

Wind and cold have dominated each of the last 3 weekends at MRG and while the upcoming holiday weekend won't exactly be tropical, it will be a lot more comfortable. We can expect some cold morning temperatures both Saturday and Sunday but reasonable daytime conditions with 20's expected Saturday and near 30 on Sunday. Saturday is a little blustery with some snow showers and Sunday appears more likely to feature some sunshine and less wind. Yes, the potential Monday, President's Day storm continues to show up on model simulations and most of those simulations take this system to our south. There's been enough disagreement on the eventual result to keep watch, but I am not of the belief this system is for us. Never say never in this business unless you really mean it and I haven't yet reached that point. 

For the first time since the middle January, northern Vermont will have to fend off a serious push of milder weather for the middle of the week. Milder than average temperatures should prevail for the entirety of the week, but Monday and Tuesday both appear innocuous. We have what we think will just be some clouds for Monday and temperatures in the high 20's followed by the same for Tuesday with readings crossing the 30-degree mark. Clouds are usually a very prominent part of New England weather when milder air attempts to scour the cold out and next week is no exception. It's the precipitation and wind we worry about in this case and a wintry mix or rain is certainly possible Wednesday, Thursday or both. This does not appear to be a storm destined to track way into Quebec however and I have a funny feeling this isn't over. Would not at all surprise me to see a trend where the cold in Vermont is able to hold it's ground and some type of snow is introduced into the forecast along with the wintry mix. 

Ensembles are indicating the reemergence of some upstream blocking in the jet stream for the final week of February. This will push arctic air back toward North America to some degree during this time frame. In this case, the blocking is forecast to set up over northeast Russia near the East Siberian Sea and will send the cold toward western North America first. The Great Lakes and New England could see a piece of this action and some accompanying winter weather though I would not expect the return of bitterly cold temperatures. The door will still be open for an inland runner type storm in this pattern. 

A bit of snow for the upcoming week as we say goodbye to the extreme temperatures and wind chill

Still dealing with some pesky winds to accompany the near zero degree temperatures Sunday. We have some stronger February sunshine to power us through as well and this will certainly help with Monday's weather which is expected to be mostly bluebird and temperatures recovering into the teens. Those winds I mentioned will still be gusting up to 30 mph Sunday and 20 mph on Monday before subsiding Tuesday. Two key indices are both switching signs today with the EPO turning positive and the PNA negative. The EPO in particular indicates a more hostile Pacific jet stream situation for the next two weeks, yet we are certainly safe for the first of those weeks. 

Tuesday's lack of wind and 20-degree temperatures will feel amazing. We start out with a little sun which will quickly give way to clouds and then the snow arrives. The storm in question isn't much to look at, but the warm advection features are excellent at producing snowfall in New England generally and this system will do so for us. Looks like a gentle 3-6 inch snow, mostly late Tuesday evening with some light snow continuing into Wednesday yielding a small additional accumulation. Temperatures will be in the 20's as this is all happening which is certainly a big improvement over the weekend. The week will then finish almost normal. Twenties for daytime temperatures, mostly low teens during the overnight and a little blustery on Thursday. Not expecting much in terms of additional snowfall with clouds and intervals of sunshine both days. 

The American GFS model output continues to sporadically spin up a storm for the President's Day holiday. The latest version as of this update had that happening on the holiday Monday. This particular model has had a absolutely horrible run of it the last several weeks and improvements are not coming given all the cuts made to our various atmospheric research institutions this past year. Fortunately, the European both the AI and OG versions continue to paint a realistic picture of the most likely outcome in the medium range forecast picture. The AI version of the European model did an outstanding job depicting the weather for the upcoming week  which consists of moderating temps but no blowtorch. Anyway, the holiday weekend looks like a fair weather situation. Lots of sunshine and excellent visibility (with storminess confined to areas well south of us) and reasonable temperatures in the 20's during the day and teens at night. Most importantly, the weekend won't feature a ton of wind (I don't think) and each of the last three have had the very cold wind and wind chill impact to deal with. 

The thaw threat is certainly alive for week 2 after the President's Day holiday. If it were to happen, it would likely be a middle of the week issue and a short term problem. I seen it going one of two ways. A bad scenario where we get torched for a day with some accompanying wind and rain. A failed warm up where the weather consists of clouds, near 30-degree temperatures and some snow or a wintry mix. Many cold winters in Vermont, such as the one we are living through, do not give in to mild weather easy. We have deep snow cover, 50 percent ice coverage on the Great Lakes, almost 100 percent ice coverage locally on Lake Champlain. These are cold feedback mechanisms that tend to work in the favor or more winter weather. That said, I would place my bet on the mostly failed warm up during the time frame in question and it will certainly be interesting to see how it plays out. 

Got a couple hours early Saturday to enjoy the new snowfall before the wind and bitter cold arrives

Another weekend arriving and another bombing offshore storm will have a big say on weather conditions. In the meantime, we start out chilly Friday and then temperatures moderate under increasing cloudiness. Wind speeds will stay tolerable and readings in the teens will make it feel rather nice and a striking contrast to weather conditions Saturday. The clipper system dropping over New York state will spread light snow over Vermont Friday night. I expect 2-4 inches of of the light and fluffy stuff and then continued light snow through much of the ski day. I've got a very important clarification or call to make regarding this. If you plan to ski Saturday, get out early. We have a few hours until about noon where wind speeds will be manageable and temperatures will hover in the 5-10 degree range. In the afternoon winds are expected to increase dramatically and this will coincide with a big drop in temperatures. I expect readings to finish the day below zero. Meanwhile, we can expect another 2-4 inches of snow during the day Saturday and perhaps an additional inch Saturday night ahead of what will be a cold mostly subzero Sunday. I was hoping winds would diminish Sunday yet they will continue to be blustery throughout the ski day. 

This is the last blast of intense chill for a while I think with the EPO change forcing a retreat and repositioning of the arctic cold. All that said, winter in Vermont will hold its ground through the 2nd week of the month. Monday starts out cold before recovering into the low teens thanks to bluebird weather. Tuesday should be a milder version of Monday. Pushes of milder weather, especially those that ultimately fail to bring said mild weather to Vermont often result in some snowfall and I expect we see some around the Wednesday time frame. This does not appear to be a significant storm and I still think several inches are possible. The end of the week does not appear to have any material mild threats with garden variety temperatures expected consisting of 20's for highs and near 10 for overnight lows. 

At the current time, the longer range ensembles are confining the storminess on the President's Day holiday offshore. We continue to see models sporadically show a storm around that weekend, but the Davis Strait block is shown to migrate closer to the Hudson Bay in that time frame which supports more of a fair weather jet stream for New England. Temperatures on the mountain should remain below freezing and there is little risk of the bitterly cold temperatures which have dominated the recent weekends such as the upcoming one. 

The adverse impacts of the EPO continue to elevate the risk of milder temperatures in the third week of February. Ensembles have yet to indicate or warn of a blowtorch however. For now it looks like a standard run of above normal temperatures which, at face value, is certainly something we can handle.  

Bitterly cold this weekend with some accompanying snow and then the chill relents

Piggybacking off the last update, I am going to savor the moment on our snowfall. We are in 10th place at the Mt Mansfield snowstake with terrific snow quality and the west has been hurting for most of the season. I had mentioned the snowiest spots in Colorado and Utah as a reference point. Another would be Tahoe, a place that has also struggled this year and one of the highest resorts there, Mt Rose, is roughly even with MRG on seasonal snowfall. The EPO is now expected to a big turn however and spend a good chunk of February in positive territory. We saw this trend commence over the weekend and it has been validated in a decisive way in the subsequent modeling. After an intense blast of cold this weekend, most of the rest of this month won't feature too much arctic cold. We still have some supportive blocking in the Davis Strait region which will help with storm trajectory, but the pattern will certainly allow for sporadic milder days and little extreme cold after Monday morning. 

Residual cold weather following the recent polar vortex drop continues to deliver cold weather for Vermont. As opposed to the wind that we dealt with much of last week, the weather now would be more comparable to western ski areas with the magnificent  blue skies, great visibility, cold overnights and comfortable afternoons. Clouds and light snow return for very early Wednesday with 1-3 inches of fluff around first tracks time. Blue skies are then expected to return later in the day and we should expect that to continue into Thursday with readings again in the teens and a bit more wind than what we had early this week. 

We have a bit more clarity now with weekend weather and there is quite a bit of it. A potent clipper system will drop southeastward and bring with it a very intense and very direct shot of arctic cold. We also have some snowfall though the ski day on Friday appears dry. Friday will actually start out sunny and subzero with temperatures again moderating to the middle teens with increasing cloudiness and tolerable wind speeds. Snow then begins late Friday evening. Limited moisture from the clipper will get enhanced by a very favorable wind off the mostly but not entirely frozen Lake Champlain. I would expect 4-8 inches of windblown powder on Saturday with challenging elements. Temperatures are likely to spend all of Saturday below zero with sustained winds of up to 30 mph with higher gusts. Clouds should break for sunshine on Sunday with temperatures close to -15 in the morning and recovering to about 5 above in the afternoon. 

I've spent a considerable amount of time analyzing the very fluid weather situation next week. We are losing the support of a friendly Pacific jet stream and the coldest core of arctic air will recede northward and westward. There are models suggesting we torch for a day next week though the consensus indication is that winter will hold its ground across Vermont and other portions of northern New England. We have the continued support of downstream blocking and we have the added benefit of some cold feedback mechanisms given the amount of ice covering the Great Lakes aggregate (for one). It's the most since 2015. I've been interested in watching the performance of the European AI model, a close, new relative of the OG European model and though it suggests temperatures get up close to freezing a few times, we get a snowy week out of htis whole deal. I like that scenario obviously, but it's early. We know Monday will remain chilly with temperatures moderating into the teens following the weekend blast of arctic cold. The middle part of next week is then likely to be cloudy with temperatures just below the freezing mark and a good chance for some accumulating snowfall. A more organized storm system is then likely to approach around the beginning of the holiday weekend. We won't have the benefit of arctic cold and I still like our odds that we can score some snow out of whatever happens. 

I've been downplayed the risk of a thaw through the first half of February and I although I think this holds, I lose confidence as we move into the 2nd half of the month. We can't fight an angry Pacific forever and eventually it's likely to get us. We also begin to move temperature climatology in a significantly upward direction for the 2nd half of the month. Nothing wrong with a little warm weather if we can keep the wind and dewpoint temperature down and needless to say, the rain away. 

 

February looking less arctic overall with chances for snow coming late this week and again next week

 Happy 5 PM sunset ! Along with the change in months comes a little more light, about 3 minutes per day if you're keeping score at home. And we're going to get the opportunity to see a few sunsets in this stretch of dry weather which is set to persist a few more days. Our nor'easter is bombing away offshore, having deposited 6 or more inches of unusally skiable powder in eastern North Carolina and leaving us with some Sunday sunshine and temperatures in the teens. Winds will be steady out of the northwest though they could have been considerably worse had the storm been closer to shore. 

Sunday will follow with a terrific bluebird Monday. Calm winds over a deep snow cover will allow temperatures to start well below zero before that sun goes to work and we sniff the 20-degree mark for the first time in a while on the mountain and it's a similar story for Tuesday. The afternoons both days should feel fantastic thanks to lower wind speeds to go along with that sunshine.  

More clouds should return for Wednesday and with the overcast comes some light snow. There's a cold push associated with this snow and this will bring temperatures from the 20-degree mark on Wednesday back into the low teens for Thursday followed by a cold Thursday night. A direct shot of arctic chill is poised to envelop Vermont for another weekend and the storm system bringing this cold is intriguing, a bombing type clipper system. Much of the energy and precipitation may fall south of Vermont though we do seem to be lined up for at least a light snow and possibly more. The snow would arrive for the back half of the ski day Friday as temperatures again recover toward the 20-degree mark, and continue through the overnight. Saturday the 7th looks blustery and frigid with temperatures on the mountain likely near to below zero. Sunday will then feature thoses subzero temps in the morning followed by some recovery during the day.   

The weekend cold on February 7th and 8th is intense, isolated to New England and quite temporary. By Monday, February 9th, temperatures will moderate across the region and the week as a whole may end up featuring a round of above normal temperatures with readings challenging the freezing mark a few times in valley locations. The thaw threat continues to appear low with the Davis Strait block anchored in place and the relaxing jet should send a storm in our direction. This appears most likely during the middle of the week. 

One of the key aspects of this update involves the gradual loss of PNA/EPO support upstream. The jet in the Pacific is expected to get a little fiery by around the 10th of the month and this should mean some much needed snow in the Rocky Mountains. To say it's been a miserable snow year out west is an understatement. Mad River Glen has double the seasonal snowfall as Telluride, DOUBLE !! We are ahead of Wolf Creek, CO and running about even with Alta in Utah. That's just incredible, two of the snowiest places in the country. Those guys will finally get a supportive pattern and a chance to exert themselves a bit. Across the interior northeast, we will need to rely on the blocking in the pattern and the support of some home grown cold in eastern Canada because I don't think it's going to be an especially arctic month with the exception of the upcoming weekend.  

Bombs Away !! Big storm offshore is strong enough to hold my attention, but too far east to produce any Vermont snowfall this weekend

Bombs away

Well, I guess I'm back in love again

Well, hey now, and around we go

This will bring me ruin 

Though I suppose it's pleasing 

I've changed the eyes I gaze in 

Still, she's just another girl

And I'll need more than a trade in 

Guess I'll have to change the world  

 

 This Bobby tune, and I really do love the guy, is the song that always comes to mind when a bombing nor'easter enters into our weather discussion. I think the song is decent overall, having grown on me in recent years after a slow start. One of Weir's best and certainly overlooked song constructions might be the song Two Djinn which came to being in his post-Jerry band Rat Dog. Fantastic album overall actually called Evening Moods and it's out of print so if anyone has a copy I'll take it. 

 

Back to the bombing nor'easter, it is absolutely mesmerizing to look at on a weather map yet it remains a miss for Vermont and most of New England. The storm will take shape near Cape Hatteras early on Saturday and get a full detonation over the Atlantic, deepening to at least 968 mb (hurricane level strength, though less consolidated) while passing about 200 miles or so east of Cape Cod. This may or may not be close enough to spread some blizzard conditions to the Cape and Islands. It is certainly not close enough to bring snow to the remainder of New England barring a major last minute shift. Storms of this magnitude have the tendency to suck all the energy out of a room, unless you're in the energy. This means a dry weekend is coming our way which will include some sunshine and excellent visibility. Temps will start out at 10 below Saturday and then recover to almost 10 degrees. Sunday's temperatures may warm a few degrees but the proximity of the aforementioned storm will turn up the volume on wind speed so plan for that. 

 

We remain chilly for the first full week of February with temperatures on a few afternoons reaching the 20-degree mark. Except for flurries and lighter snow showers, most of the period will be dry since the unsettled part of the jet stream is expected to stay situated south of us. We see changes in this regime very late in the week and could have an interesting weather situation to deal with in the Friday, February 6th to Saturday, February 7th time frame. A lesser surge of arctic air to go along with a robust looking clipper system will combine to create another storm opportunity for us. The weekend in question is also likely to be windy and cold again whether we get some significant snow or miss most of it. 

 

The 2nd full week of February still has a nice look to it with the jet stream blocking through the Davis Strait offering us some protection against any potential thaw and creating an environment conducive for east coast storms. We lose a bit of life toward the middle of the month from the negative EPO though the index remains favorable throughout the period. We have it going right now and one of the most important aspects to keeping this train moving is thaw avoidance and this current outlook is cooperating in that regard.
