SYNOPSIS
Mainly dry conditions tonight and tomorrow with a spot shower and rumble of thunder possible Monday afternoon. Back door cold front will cool down daytime highs tomorrow afternoon. Tranquil and dry weather prevails into midweek. Our weather pattern then turns more unsettled and a bit more humid too for Thursday and Friday, with several opportunities for showers and embedded thunderstorms. Localized downpours are possible. Still a chance for pop-up showers and t-storms on Saturday, although with less coverage.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/

Very subtle and weak shortwave drops south across the region tonight which could bring an isolated spot shower in western MA and CT.
However, weak forcing and dry air below 10kft will likely evaporate most rain before it can reach the ground resulting in just virga and perhaps a sprinkle. Increasing mid and high level cloud cover tonight along with dewpoints in the 50s will keep overnight lows warmer then last night only dropping into the upper 50s to low 60s.

SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/

Upper level closed low and cold pool to the east will send a back door cold front into the region Monday. High temperatures in eastern MA will peak early in the day in the mid to upper 70s, before abruptly dropping down to the upper 60s to low 70s as the back door cold front arrives. Further west in the CT river valley, the back door cold front will struggle to reach that far west, and high temps should be able to reach the low to mid 80s. Mainly dry conditions again monday as a weak ridge and area of high pressure builds to the west. There is a low chance for an isolated shower and rumble of thunder in the late afternoon across western MA and CT as roughly 500 J/kg of CAPE builds. Any convection that does fire will be fighting rising heights and very meager mid level lapse rates around 5 C/km. With little to no shear, any convection that forms would be an isolated single cell. There could be sub-severe wind gusts with any showers/thunderstorms tomorrow afternoon with steep low level lapse rates around 10 C/km and soundings showing an inverted V shape in the boundary layer.

Any showers/thunderstorms that form Monday afternoon/evening will quickly dissipate after sunset with the loss of daytime heating.
Mainly dry conditions overnight Monday with low clouds and fog possibly rolling in off the waters due to prolonged onshore flow.
Overnight lows drop into the low to mid 50s.

LONG TERM /TUESDAY THROUGH SUNDAY/

Highlights:

* Generally dry Tue and Wed with mild temps inland, cooler coasts.

* Turning more unsettled and muggy into Thurs and Fri with several opportunities for showers/embedded t-storms. Localized downpours possible. Temps seasonable to slightly cooler than normal with clouds/rain around.

* More pop-up showers/storms Sat, although with a bit less coverage.

Details:

Tuesday:

Tranquil conditions expected for Tue with sfc high pressure in control and midlevel heights rising. With guidance coming into better consensus on unsettled weather conditions moving into the latter portion of the week, Tue is likely to be the pick of the workweek. While coastal areas expected to be kept cooler due to seabreezes (highs mid 60s/around 70), full sun and dry weather inland should boost highs into the 70s to lower/mid 80s. A bit more of an increase in cloud cover over western CT/MA but still dry with lows in the mid to upper 50s.

Wednesday:

Should be able to eke out another dry day for eastern MA and RI on Wed as surface high pressure shifts offshore. Some hints in latest guidance of isolated diurnal convection as 500 mb heights start to fall with modest instability, although the better risk looks to reside to our north and west. Left a slight chance PoP mention during the afternoon for the CT Valley and the Berkshires, although drier weather to prevail most of the time. Risk for showers then increases later Wed evening/early Thurs AM as we start to feel the effects of a seasonably-strong upper level low over the Gt Lakes region. Thus indicated steadily increasing PoP from west to east into the solid Chance range (30-50%) by Thurs AM. Should see highs in the 70s to low 80s, and lows in the lower 60s with humidity levels rising.

Thursday into Friday:

Models are coming into better agreement that this period looks quite unsettled with widespread showers and embedded t-storms. Upper level low combined with rising humidity levels and a modest degree of instability could favor local downpours, though the lack of stronger instability would be a deterrent to stronger storms. Thurs looks to be the wettest period, with NBM 4.2 probs of rain over a half inch are in the moderate range (30-50%), and are lower to moderate (15- 25%) for 24 hrs rains over 1 inch. Brought PoPs up into the Likely range for showers and t-storms on Thurs. Most models show we get into a dryslot of sorts for Thurs evening with decreasing PoP to around 30-40%, then more pop-up showers/storms on Fri as a secondary shortwave disturbance moves through. Still unclear if these downpours may cause any hydro issues, though that risk is mitigated to an extent by the recent spell of dry weather we've had.

With a lot of cloud cover around along with periods of rain and thunderstorms, expect temps to cool off into the 70s for both Thurs and Fri, though will feel a little more muggy with dewpoints in the mid 60s.

Saturday:

Still some risk for diurnal showers/storms on Sat, although the upper low begins to deamplify and lifts toward the northeast into Canada.
