SYNOPSIS

Mild today with increasing clouds. Gradually turning colder tonight into Wednesday. Snow showers possible Tuesday night through Wednesday, especially across eastern Massachusetts. Any possible snow amounts will be light. Milder temperatures return for next weekend with our next shot at widespread precipitation not until next Sunday and/or Monday.

NEAR TERM /UNTIL 6 PM THIS EVENING/

10 AM update...

Mostly dry conditions continue this morning as the main low pressure center continues to slide east; just some light showers over the Berkshires at this hour. This will be the most sun we see today, as cloudcover and widely scattered showers move in associated with a subtle shortwave that slides by around late afternoon.

Previous Discussion...

Monday...

* Dry & mild along with some sunshine

Short wave trough over VT/NH early Monday morning exits eastward across Nova Scotia this afternoon. Behind this feature, short wave ridging and associated subsidence provides dry weather for SNE.
Predawn clouds and areas of fog will lift and give way to brings of sunshine later this morning. Although, cooling 500 mb temps will result in diurnal clouds to develop and yield mostly cloudy conditions this afternoon. These cooling temps aloft may yield a spot shower this afternoon, otherwise dry weather prevails. Post frontal airmass is not very cold, therefore mild today with highs in the lower 50s, upper 40s high terrain. Although a cool westerly breeze develops this afternoon, 15-20 mph.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/
330 AM update...

Tonight...

* Turning colder

Weak short wave trough over NY state at 00z moves across New England this evening. Forcing for ascent is weak and moisture is limited.
Thus, only expecting some cloudiness and perhaps a few sprinkles or flurries. Behind this short wave, CAA increases with overnight with lows by morning in the upper 20s and lower 30s.

Tuesday...

* Mainly dry, cooler with partial sunshine

Behind departing short wave, subsidence provides mainly dry weather and some morning sunshine. However, cold air aloft likely results in diurnal clouds developing yielding mostly cloudy conditions in the afternoon. N-NW winds 10-15 mph. This low level trajectory with cooling temps aloft/steepening low level lapse rates streaming over SSTs around +10C, may result in ocean effect rain showers for the outer Cape. Dry weather elsewhere with highs in the lower 40s, upper 30s high terrain.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/
Highlights

* Combo of an inverted trough and ocean enhancement bringing snow showers from central MA to RI eastward Tue Night through Wed. Only exception is the central/outer Cape and ACK where there is a rain/snow mix. Minor accumulating snowfall possible.

* Dry and quiet weather for the rest of the week into Sat. Near to below normal temps on Thu, but will be trending upward late in the week and through the weekend.

* Next shot for widespread precipitation comes Sun into Mon.

Tuesday Night through Wednesday...

Caught under cyclonic flow during this timeframe. A trough will be situated over the TN to Mid Mississippi River Valley Tue night and dig into the Carolinas by early Wed before lifting offshore well to the south/SSE of our region. An inverted sfc trough will still be nudging into our region Tue Night through much of Wed, but should slide offshore by Wed Night.

There will be a combo of lift from the inverted trough along with ocean enhancement. Still some uncertainty with how much QPF we are able to squeeze out of roughly the 25th to near normal PWATs for this time of year. The GEFS/EPS and GEPS guidance all show our PWATs around 0.25-0.4 inches. Given the favorable fetch and upper level flow should see ocean enhancement, especially across SE MA. On top of this temperatures will be somewhat marginal with the best lift outside of the dendritic growth zone. Did bump up the default WPC QPF slightly toward the GFS, which falls more in line with the clustering per WPC Superensemble for PYM/OWD and BVY. The result is a few hundredths across locations further inland and perhaps a quarter of an inch across Plymouth county in MA.

Given the meager moisture and marginal temps, especially along the coastline am thinking anywhere from a coating to an inch is possible. There is a low prob (10-30%) of snowfall amounts greater than 1 inch. Risk is highest for Plymouth county in MA, but there is discrepancy amongst ensemble and deterministic guidance. The GFS/NAM along with GEFS indicates the greatest shot, with GEFS probs of 40- 70 percent of 24 hr snow AOA 1 inch with a 10:1 SLR. The ECWMF along with EPS is much more muted with probs around 10-30% and the GEPS indicates nil probs at this point. Will be interesting to see when we get into the high res window. For now am advertising a coating to an inch in the forecast. Could even see a dusting a bit further inland across RI/central MA. At this point not anticipating much of an impact, but a decorative snowfall. Across the central/outer Cape and ACK temps likely too warm for any accumulation with a rain/snow mix.

Have bumped up precipitation chances from the default NBM as guidance is in pretty good agreement for shower activity throughout the day. Wanted to indicate a likely shot for showers given the forcing in place along with favorable flow for ocean enhancement.
Temperatures below normal during this timeframe with highs in the 30s across the region. The Cape/Islands will have highs in the low 40s.

Wednesday Night through Saturday...

Shortwave ridge builds from Ontario Wed night into New england by early Thu. A more amplified ridge builds from the Upper Mississippi River Valley Thu AM into the Great Lakes region by early Fri. The ridge builds into New England by late Fri. The ridge builds offshore sometime later on Sat. High pressure nudges in from Quebec and the SE US Wed night through Thu. The high continues to nudge in Fri through Sat as it builds offshore.

Dry and quiet weather anticipated through this timeframe with high pressure nudging into the region. Still chilly on Thu with NW winds gradually shifting to the W/WNW late in the day. Will have the coldest temps Thu AM with lows in the teens across the interior and the 20s along the coastal plain. On Thu high temps will be in the 30s across the region. Should see temps rebounding nicely late in the week and heading into the weekend.
Will have prolonged WSW to SWly warm air advection through this timeframe. This will warm temps to seasonable levels on Fri and above normal for Sat. Highs by Sat warm into the upper 40s and low/mid 50s.

Sunday and Monday...

A deep trough will be situated over the Mississippi River Valley Sat night. The trough will lift toward the TN Valley and Great Lakes region by early Sun. The trough lifts into the eastern Great Lakes late on Sun and New England on Mon. A frontal system lifts into and through the region during this timeframe.

This is our next opportunity for a more widespread precipitation event. Still a bit of uncertainty on timing and intensity this far out, but guidance in pretty good agreement for Day 7+. At this point in time given the track of the system am anticipating a rainfall event, which could potentially be heavy at times. The NAEFS SATA table indicates PWATs of 1.5-2 STD above model climo this far out.
On top of this have a meridional component of the wind around 1.5-2 STD above model climo at this point with deterministic guidance showing a southerly jet of 30-60+ kts. Still need to see how things evolve as the week progresses, but could be our next shot for impactful weather. Temps still near to above normal.
