Long Term

Key Points

A strong Cold front will bring blustery, cold, and dry conditions on Tuesday and Wednesday.
Warming trend Thursday and Friday with a return to wet conditions.
Wet and unsettled weather continues into next weekend, but details remain uncertain this far out.

Tuesday and Wednesday

A strong cold front moves through the region overnight Monday into Tuesday, helping kick out the remaining rain/snow showers.  There could be some snow showers/squalls as the cold front enters western MA with a strong pressure rise/fall couplet and good low-level moisture.  However, good low-level lapse rates are lacking due to diurnal cooling.  The cold front weakens as it moves through the region. Thus, the threat of snow squalls/showers will diminish quickly into central and eastern SNE. Strong CAA will bring daytime high temps on Tuesday and Wednesday into the low to mid-40s, while the wind chill factor will make it feel like the 30s.  Overnight lows Tuesday night will be quite chilly, in the low to mid-20s. WNW winds and diurnal heating will promote mixing up to, if not above, the 800 mb level, where winds will be around 40-50mph.  With super adiabatic lapse rates near the surface, would not be surprised to see gusts of 40-50mph frequently reach the surface during the day Tuesday.  Dry and sunny conditions expected both days as high pressure builds in.

Thursday and Friday.  

Winds turn southerly on Thursday in response to an approaching warm front and surface low over the Great Lakes.  Temps rebound into the low 50s, but cloudy and wet conditions return.  The best chance for precip looks to be Thursday night and Friday as better forcing arrives from the shortwave and a reinforcing warm front. 

Saturday and Sunday. 

Guidance is in surprisingly good agreement heading into next weekend as a deep cut-off trough exits the SE US and works north up the eastern coastline.  This would bring continued wet and unsettled weather to the region for next week.  However, with this system being a week out, details remain uncertain as the pattern could easily change between now and then.
