Synopsis for massachusetts and rhode island coastal waters - A few widely isolated showers and Thunder this morning and drier this afternoon. A decaying low pressure system brings light rain to the waters overnight and into Wednesday. Another chance for light rain on Thursday, primarily for the northern waters, then drier on Friday. Looking head, unsettled conditions persist into the upcoming weekend.

SYNOPSIS
A backdoor cold front will bring much cooler conditions with considerable cloudiness today. Unsettled mid to late in the week due to a backdoor cold front nearby. This could bring spotty showers and keep us a bit cooler, but there is a significant amount of uncertainty with the fronts location.
Better shot for more widespread showers late Saturday into Sunday as a frontal system slides through.
NEAR TERM /UNTIL 6 PM THIS EVENING/
910 AM Update...
* Considerable cloudiness but generally dry for most of today * Highs in the 50s at the coast and 60s further inland
Shortwave energy and a burst of mid level instability was still resulting in a cluster of showers and embedded t-storms from parts of upstate NY into southern NH and southern Vermont. Some building upper level ridging will likely keep the bulk of this activity to our north today. We may see a few brief showers graze areas near the NH border through lunchtime.
Otherwise...expect light onshore to result in considerable cloudiness with mainly dry weather.
The clouds and onshore flow will hold highs in the 50s along the coast with 60s further inland. Mildest of the readings will be found in the Lower CT River Valley...where some middle to even upper 60s are possible
Meanwhile
along the immediate eastern MA coast temps will generally remain between 50 and 55.
We should mention that additional showers and embedded t-storms will develop to our west later today across NY State. But this activity will not impact us until this evening and probably in a weakening form.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/
Tonight
A modest frontal wave associated with a mid-level low at 850 hPa moves across southern New England overnight bringing additional rounds of precipitation. Not expecting any convective activity as there is not expected to be any instability in the atmosphere.
Precipitation accumulations will be limited to around a tenth of an inch or less. Overcast skies will limit overnight low temps to the low to mid 40s across most of southern New England with easterly winds becoming more northeasterly after midnight.
Tomorrow
Tomorrow, northeasterly winds develop behind the departing mid-level low allows a backdoor cold front to push over the eastern portions of southern New England. This will continue to support cloudy skies, cool temperatures, and perhaps a few sprinkles or drizzle along the east coast through the mid-morning hours. Across the interior and western MA/CT however, a mid-level ridge axis is expected to build far enough east to advect a substantially warmer air mass over the CT River Valley where high temps in the mid to upper 60s will be in the cards while the areas east of the backdoor cold front across eastern MA and RI would stay in the low to mid 50s. Confidence is pretty low with respect to how far west the cooler air mass will extend, but generally expect locations east of the I-95 corridor to be much cooler than locations west of the I-495 corridor with a gradual cooling trend from west to east for the areas inbetween.
While cloudy conditions are expected during the morning into perhaps the early-afternoon hours, there should be at least partial sunshine across the interior developing by mid-afternoon.
LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/
Highlights:
* Good amount of uncertainty in the extended forecast with timing and expect location of showers.
* Backdoor cold front on Friday. This could bring spotty showers and keep us a bit cooler, but there is a significant amount of uncertainty with the fronts location.
* Unsettled with rain chances continues this weekend as a front moves across the region.
Wednesday Night:
Cloudy conditions overnight with any lingering showers coming to an end before midnight. Wind shifts to the south, this will help keep it mild overnight, minimum temperatures lower and middle 40s. Not out of the question patchy ground fog develop as the dewpoints are in the 40s overnight.
Thursday and Friday:
There is some uncertainty with this part of the forecast as global guidance remains in some disagreement. A weak surface low pressure system moves from northern New York towards southern New England along a frontal boundary. The good news, much of the deterministic models are showing minimal QPF, no threat for a washout. In fact, much of the guidance over southern New England supports only a few hundredths of an inch to a tenth of an inch. For what it is worth, the NAM at 00z kept much of the area dry, while the GFS being the wetter of the models. The uncertainty lies with the position of the front and the path the low takes. Kept the highest POPs, 20 to 30 percent mainly areas northeast of ORE, ORH, and TAN. But given the uncertainty, did leave minimal POPs for areas southwest which would give us 'Slight Chance', the lowest category for precipitation. As for temperatures, still fairly mild despite the clouds and rain chances, generally in the 60s with the immediate coast, Cape, and Islands in the upper 50s. CT River Valley will likely be the warm spot yet again, highs are in the upper 60s to lower 70s.
Friday does look to be on the drier side, at this point, with weak surface high pressure in place and the mid-level just to the west.
While this would typically mean a milder day, the signal is there for another backdoor cold front to sweep across southern New England and the temperatures cooler than normal. Wind direction on Friday becomes northeast and drives cooler airmass over the region. Highs are generally in the mid 50s along the eastern Massachusetts coast and away from the water the temperatures are generally 59F-62F, with a few spots in the lower CT River Valley reaching 63F-66F.
Saturday through Monday:
Mid-level ridge shifts east and is planted over the New England states with a warm front arriving during the afternoon with the potential for scattered showers, it is not until Sunday the ridge moves off shores and a cold front moves through - the timing on this still is uncertainty and leaned on NBM guidance given how far out in the forecast we are reaching to. With this uncertainty kept with NBM temperatures, highs 60F-65F, and lows 45F-50F. A ridge sets up to our west on Monday and trends drier and mild with highs creeping back to the low 70s.
AVIATION /18Z TUESDAY THROUGH SATURDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
18z TAF Update...
Through tonight...Moderate Confidence.
Mainly VFR conditions into early evening...but a cooling boundary layer should result in MVFR-IFR conditions developing tonight with even some localized LIFR conditions given moist onshore flow. Another round of showers will move in from the west after 23z/00z. We can not rule out isolated thunder with it briefly across the distant interior...but we expect a weakening trend as the activity pushes east into a less favorable environment. So for much of the region mainly just showers but a few downpours are also possible. A few showers linger especially towards the Cape/Islands through daybreak...but the vast majority of the activity will have passed the region by 06z/07z. E winds shifting to the NE at 5 to 10 knots tonight.
Wednesday...Moderate Confidence.
IFR-LIFR conditions early Wed morning will gradually improve to MVFR and even VFR conditions in some spots through the afternoon...but this will be a slow process and timing will need to be refined. After any remaining showers depart early Wed morning, mainly dry weather will prevail Wed other than perhaps a brief spot shower. NE winds 5 to 10 knots.
Wednesday night...Moderate Confidence.
MVFR-IFR conditions will probably become dominant again as the boundary layer cools again Wed night. A few showers may spill into our northern zones through daybreak Thu...but much of Wed night will feature dry weather with nothing more than a spot shower. Winds becoming light S.
