SYNOPSIS
Gradually turning colder tonight into Wednesday. Snow showers possible Tuesday night through Wednesday, especially across eastern Massachusetts. A few inches of accumulation is possible. High pressure builds over the Wednesday night and Thursday bringing dry but cold weather. This high moves east of the region Friday into Saturday...allowing for temps to moderate especially by Saturday with dry weather prevailing. A strong storm system may pass to our west Sunday into Monday bringing the potential for a period of strong southerly winds, heavy rain and a period of unseasonably mild temperatures.
NEAR TERM /THROUGH TUESDAY/
Our final mild day for a while is coming to a close as we see increasing clouds and spotty showers over the interior resulting from the shortwave and colder temperatures aloft. These scattered showers may continue through about 06Z tonight as the shortwave moves off and is then replaced by weak mid level ridging for much of Tuesday. This ridging and its associated subsidence will keep things dry on Tuesday and even provide a good amount of clear skis/sun on Tuesday morning before diurnal clouds blossom in the afternoon and thicker clouds overspread from the south in the evening. Meanwhile, temperatures will be noticeably colder on Tuesday thanks to cold advection in the mid/upper levels on NW flow; this will lead to highs about 10 degrees colder on Tuesday, in the upper 30s/low 40s.
SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY/
Tuesday night and Wednesday morning are the more interesting portion of the short term forecast period as we'll see as a combination of a nearby inverted trough and ocean enhancement will bring a period of steady snow to eastern MA, especially southeast MA. At the synoptic scale we'll have a trough digging into the mid Atlantic overnight and crossing New England on Wednesday while at the surface an inverted trough will be lingering offshore. This will provide a focus for low level convergence/lift and produce precipitation in the form of snow showers for the interior. What is more interesting is the potential for this to be enhanced by the warm ocean. SSTs are currently around 10C (50F) offshore which is cold for most purposes, but relatively warm compared to the air above it. Surface temps will be in the low 30s during this time with air up at 800 mb (height of the inversion) around -10C (14F). That much difference should be enough to help generate fairly steady snow showers over eastern (and especially southeastern MA). Though model soundings indicate the best omega (forcing) below the DGZ, we should be able to squeeze out generally 1-2 inches with pockets of 3 inches possible across Plymouth county and lesser amounts further north and west.
Confidence at this time frame is low on specific amounts, but GEFS ensemble guidance indicates a 50-60% chance of >1 inch while the EPS is much less excited about it (20-30%). What's more certain is the colder airmass in place on Wednesday which allows for these snow showers will also bring colder high temperatures, only topping out in the mid to upper 30s. The warmest location will be Cape Cod and the islands where any showers should fall as rain.
LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/
Key Points...
* Dry but cold Wed night into Thu * Temps moderate Fri & especially Sat with mainly dry weather * A period of strong winds/heavy rain & very mild temps Sun-Mon
Details...
Wednesday night and Thursday...
The upper level trough axis will have shifted east of the region by Wed night and Thu. The result will be dry but cold weather as a ridge of high pressure builds in from the west. Airmass overhead is chilly...so we expect temps to run a bit below normal for this time of year. Lows Wed night should mainly be in the teens to the lower 20s with highs Thu generally in the middle to upper 30s.
Friday and Saturday...
The long range guidance is in very good agreement in the surface high pressure system shifting east of our region Fri into Sat. At the same time...both the GEFS/EPS indicate significantly rising height fields. This should allow high temperatures to recover well into the 40s on Fri and probably into the 50s by Sat for many locations. Dry weather should prevail on both Fri and Sat given any synoptic scale forcing well to our west.
Sunday and Monday...
There is the potential for an inland runner sometime Sun into Mon...which if pans out would bring the risk for a period of strong southerly winds, heavy rain and very mild temperatures.
A potent upper level trough will be approaching from the west and induce a strong southerly LLJ. While this is a 6-7 day forecast and there is a lot of uncertainty...the guidance indicates a few anomalous signals that will need to be watched closely. The GFS/ECMWF/CMC models indicate a southerly LLJ on the order of 70 to 90 knots as strong low pressure passes well to our northwest. The GEFS/EPS indicate both the southerly LLJ and PWAT plume to be 2-3 standard deviations above normal...which is a pretty good signal this far out
In addition
the CIPS analogs are showing some modest probabilities for a period of 40+ knot wind gusts. And the CSU Machine learning probs are indicating a low risk for convectively induced severe winds.
Whether or not any of this materializes remains to be seen...but it is something to watch in the coming days. It is way too early to say much more at this time...but a period of strong winds, heavy rain, very mild temps and even a bit of convection are not out of the question.

Tuesday night...Moderate confidence.
VFR/MVFR to start with MVFR cigs starting on the east coast of MA in light snow/rain showers, expanding west over all of eastern MA. Southeast MA terminals outside of Cape Cod (where it will be too warm) may see light accumulations of 1-3 inches but confidence in accumulation is low to moderate. Light N/NE winds.
