SYNOPSIS
A backdoor cold front will bring much cooler conditions, clouds, and spot showers 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/

3AM Update

A broken line of scattered moderate to heavy showers is currently pushing east across southern New England. Elevated instability, a very subtle short-wave disturbance aloft, and low-level convergence ahead of a warm frontal boundary to the south are the driving factors behind this nocturnal elevated convection. Overall, the synoptic forcing is weak, but strong deep layer shear and 500-1000 J/kg MUCAPE has been enough to support a few rumbles of thunder and areas of moderate to heavy precipitation this evening. Showers with embedded thunder will continue from west to east through about sunrise before a mid-level ridge axis shifts east and shuts down the upper-level support.

Following the diminishing showers will be a cool/cloudy day across southern New England as low-mid level winds south of the warm front overrun cooler air over southern New England. At the surface, high pressure to the north will support a steady easterly flow allowing for a cool sea-breeze along the east coast. Expect much cooler temps than yesterday with highs in the low 50s along the coast and mid to upper 50s across most of the interior. CT River Valley should be the warmest location with highs getting into the low 60s. Precip chances begin to increase across western MA/CT by late evening as a frontal wave approaches from the west.

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 /08Z TUESDAY THROUGH SATURDAY/
Forecast Confidence Levels:

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

06Z TAF Update

Through 12Z... high confidence in flight categories, moderate confidence in precipitation potential.

VFR for locations east of ORH continue through morning with MVFR at and west of ORH. Generally light easterly winds at the terminals. A few showers with perhaps VCTS is possible at and west of ORH but confidence is low as and thunderstorms should be isolated in nature. Have only mentioned VCSH in the 06Z TAFs.

Today... High confidence.

MVFR ceilings continue to stay focused generally west of the I-495 corridor. Persistent easterly winds. East of I-495 expect mid-level clouds around 050 for the day with some possible breaks above 10 thousand feet during the afternoon over The Cape/Islands terminals.

Tonight.. Moderate confidence.

IFR/MVFR ceilings overspread the rest of southern New England overnight. Winds persist out of the east through about 06Z before shifting northeast between 06 and 12Z. Expect periods of SHRA between 00 and 06Z.

Tomorrow... Moderate confidence

MVFR/IFR conditions should persist through late morning with some improvements to VFR possibly during the early to mid afternoon hours. Northeast winds become more easterly by the evening hours.

KBOS TAF...High confidence in VFR, moderate confidence on afternoon cloud bases.

Generally onshore flow prevails through the TAF period with a steady sea-breeze settling in by 15Z. High confidence in VFR ceilings. While cloud bases are generally expected to persist around 5000 feet, there is expected to be a region of higher bases over east/southeast MA this afternoon. Not expecting the higher bases to extend north over BOS, but can't rule out the possibility of higher cloud bases up to 10000 feet after 18Z before falling back to MVFR/IFR tonight.

KBDL TAF...High confidence in TAF.

MVFR persists today before possible deterioration to IFR overnight. Some showers and a rumble of thunder possible over the next couple of hours (06-09Z).

Outlook /Wednesday Night through Saturday/...

Wednesday Night: MVFR/IFR conditions possible. Patchy BR.

Thursday: Mainly MVFR, with areas VFR possible. Breezy. Slight chance SHRA.

Thursday Night: Mainly VFR, with areas MVFR possible. Breezy.

Friday: Mainly VFR, with local MVFR possible.
