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. 

 

 

First half of February looks excellent with less intense cold next week and good storm potential thereafter.

 We have a nice little visit form the polar vortex late this week. The feature is actually expected to weaken and then drop over the eastern Great Lakes on Friday and then help to spin up a weather feature for the weekend. More on that in a bit. The cold weather in Vermont peaked last weekend but will remain very chilly with wind for the rest of the week and the weekend. Temperatures will start out each of the next three days (Wednesday, Thursday and Friday) a shade below zero and rise to the 5-10 degree range on the mountain (15 in the valley) Wednesday and Thursday and then only 0-5 on Friday. The wind is expected to create a material chill factor during the whole period blowing 10-20 mph. Snowfall will be limited to flurries for the rest of the week. 

The weekend weather map sure is interesting. The PV feature I mentioned will spin up a strong area of low pressure that is expected to deliver parts of eastern North Carolina and even  Cape Hatteras an unusual snowfall. This type of setup, especially with the polar jet weakening, can mean that a storm like this can move up the coast and be a big snow producer for the northeast. There are models that are showing this to an extent, but I am feeling increasingly confident the effects of this will miss Vermont (except for the wind). The storm probably stays offshore following the North  Carolina hit and this will mean a weekend featuring sun, wind and moderating daytime temperatures that actually might make the teens both days. It's worth keeping an eye on though I do consider this the most likely outcome. 

We haven't had a chance to discuss February weather too much with the short term and wintry weather situation consuming much of our attention. In short the first half of the month looks excellent. The storminess in the Pacific is never fully going to eliminate the negative EPO which has largely powered this exceptional winter we've had so far. With the PV expected to weaken and move south this weekend, the cold will relent somewhat, but the east coast and especially New England is expected to remain cold. Can we make use of that cold and produce some snowfall ? Possibly, though that appears more likely as the week progresses and not on Monday and Tuesday, the 2nd and third of the month. 

The 2nd full week of February looks interesting. The jet in the Pacific remains supportive while a blocking mechanism develops in the jet stream over the Davis Strait and becomes one of the dominant features for the entire Northern Hemisphere. I get the sense that this is not a setup that will necessarily produce an arctic outbreak and rather a rather multiple stormy scenarios for many places including us. Best of all, the risk of a thaw appears quite low and we wouldn't want one of those disrupting the excellent run we've been on. 

Just a beautiful cold powder day Monday and very chilly balance of the week accompanied by wind

Hope folks enjoyed the beautiful cold gentle snow we got Sunday evening. Winds were pretty ferocious closer to the coast while on the periphery of the storm such as our spectacular location, we saw a nice gentle wind to accompany the snowfall. It doesn't happen often and at these subzero temperatures, it may have gone unnoticed. 

Snow will continue throughout Monday and will generally fall at a lighter intensity. Some of the higher resolution model data suggests that this lighter snow in the morning will actually intensify a bit as the ski day progresses. Winds are expected to pick up just a bit, blowing in a favorable northwesterly direction which will help enhance some of that lingering moisture. We have a slight improvement to report on temperatures which are now expected to climb to about 10 (no such luck on the upper mountain, I am afraid). Still looking at a storm. total of over a foot and likely in that 18-24 inch range. Most of it will fall before the ski day begins while 4-8 can be expected throughout the day. 

The polar vortex is expected to spin its way into southeastern Canada, with a weakened version dropping right over northern Vermont late this week. The cold has in fact peaked already, having done so on Saturday into early Sunday though the pattern and the presence of the vortex will continue to support some extreme chill and we can also expect an increase in wind. Some light snow is likely late on Tuesday and more flurries for the balance of the week bringing a light accumulation at most. Theme for the rest of the week appears to be dry and cold and we can expect some significant wind chill to go along with intervals of sunshine. The warmest afternoon appears to be Tuesday with maybe a high close to 10 degrees. Wednesday, Thursday and Friday will see readings generally below 5 above on the mountain along with that wind I mentioned which will likely be 25 mph in exposed areas. 

The remnants of this vortex of cold is expected to turn the pattern very amplified this weekend, generating a storm that for now is indicated to stay offshore. If this remains the case, the January 31 to February 1 weekend could be sunny with temperatures moderating slightly to the 10-15 category. It's also possible, not likely that the storm hugs the coast and becomes a factor in our weather picture, providing additional snow. 

The first full week of February is expected to feature a temperature moderation and I would expect some opportunities for snow. Parts of the country should get a chance to thaw out and melt some snow in early February, but I don't see that as a likely scenario in Vermont.
