Warm weather could peak Monday with a return of snow possible late next week

We continue to chip away at the very mild period still looming in our forecast. No, we certainly haven't ridded ourselves of the warmth entirely as I am sure readers already know, yet this update will further confine it to a few days. I continue to like Sunday's weather over Saturday's mostly for the purposes of visibility. I think it will take some work to scour the low clouds and fog away from the region though models do suggest this ultimately happens. Temperatures will spend some time in the 30's in the morning and then rise into the 40's during the afternoon as southwest flow kicks into a higher gear. Fortunately, the rain appears mostly light during the day Saturday and there are a few pockets of freezing or drizzle indicated as part of that colder morning. A batch of heavier rain, of about a quarter inch, is indicated for Saturday night and this should all be out of the way for Sunday. Temperatures are well above freezing on Sunday and this consists of 40's on the mountain and low 50's in valley areas. Visibility should be much better as I mentioned with clouds breaking for some blue sky. 

If you like bluebird warmth, I think Monday is your day. It's the full on torch and not too much in the way of cloudiness is indicated. Readings are likely to reach 60 in valley areas, 50 on the mountain and the coldest place in all of New England is probably Cape Cod just become of their proximity to marine air. Tuesday appears to be a cloudier version of Monday with much of the day featuring the same mild breeze. A storm containing a boatload of moisture begins to organize and approach the region Tuesday night into Wednesday and we continue to see a slow trend consisting of some cooling air enveloping the northern most parts of interior New England. If you're hoping to get on the colder side of this storm, we need the trend to continue since the storm is shown to track right up the St Lawrence River on Wednesday as of now. The eventual track will have a big impact on temperatures Wednesday though the precipitation type still appears most likely wet. Some arctic air appears to be involved in the shift toward colder weather on Thursday and we can introduce some snow into the forecast late on Friday for Saturday. 

We have about 6 days of wintry weather in association with this colder period with the hemispheric jet stream view only providing us tepid support and I should note the AO never goes negative. The latter in particular would argue for only a temporary period of below normal temperatures. The big question relates to a potential storm and jet stream amplification around Sunday the 15th (still 9 days away). This could become a big snow producer, might end up producing mixed precipitation or could might end producing very little at all. It appears more certain that we get a round of intense cold around March 17th and 18th and then the cold relents thanks to a lack of the aforementioned teleconnection support.
