SYNOPSIS.

Low pressure brings a wetting rain to eastern MA and RI this Wednesday. Gusty north-northeast winds will also impact coastal MA. Low will lift north into Maine by early Thursday bringing a mostly dry, seasonable day to the region, as winds shift to the west. Very warm weather with above normal temps returns Friday and Saturday, followed by increasing humidity for the first half of next week. Generally dry weather is expected through the weekend with the best chance for scattered showers and a few thunderstorms mainly sometime Tuesday into Wednesday.

NEAR TERM /UNTIL 6 PM THIS EVENING/.

Light shower activity that has brought a few hundredths of an inch of rain to southeast MA and RI will continue to pivot westward into interior southern New England through the morning hours. Several layers of dry air, one around 900mb and one around 700 mb, have prohibited the formation of a more widespread rain shield as of this writing, but as heavier precipitation begins to move in across the outer Cape and Islands, these layers should begin to saturate, bringing, for a brief period of time, more stratiform precipitation to our southeastern zones.

Unfortunately, it seems like both the CAMs and Global models are struggling to resolve this mid and low level dry air, suggesting that widespread heavy rain may impact portions of our region. Both the GFS and HRRR try to bring a substantial swath of 1.5" to 2" QPF to the islands and outer Cape, likely because of convective feedback driven by convection over the ocean to our southeast. A more realistic solution, given the dry air and patchy nature of showers this morning, may lie with the 00Z run of the ECMWF, which estimates QPF around 0.75" over the islands and Cape Cod, and extending a beneficial swath of 0.25-0.5" precipitation to the I-95 corridor.

Some models, like the NAM 3k, are trying to resolve a secondary surge in precipitation extending from approximately Norfolk county west towards Springfield along the axis of an approaching shortwave feature. While our forecast does not currently include significant amounts of QPF from this feature, there is potential for this system to overperform, in say, the Springfield/Chicopee/Worcester areas. Unfortunately for those in Connecticut, model guidance agrees that the western extent of the precipitation shield will leave the region mostly dry, with just a few hundredths to maybe a tenth of an inch of QPF possible; primarily this morning before the low begins to lift north.

In addition to the ongoing and expected wetting rain, a wind advisory is in place across Cape Cod and Nantucket due to strong winds between 950 and 900mb. The GFS suggests that 50 kt winds will be present around 900mb, and while 50 kt gusts are not anticipated to reach the surface, given the lack of pressure falls and significant temperatures gradients that come with late Summer, some significant gusts to 40 kt could reach the surface, primarily at ACK.

Given the scattered showers and northeasterly flow on Wednesday, temperatures are expected to be quite cool for mid August. Several locations across eastern MA may have actually achieved their high temps already, cooling modestly into the low and mid 60s for the remainder of the day. Locations in the CT River Valley that remain mostly dry should be the warmest locations today, with temperatures in the low and mid 70s.

SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/. Highlights .

Low pressure begins to lift into the gulf of Maine, and eventually in to Maine, this evening, which will cause winds to shift from the N/NE to the W/NW. Scattered showers will likely linger into the early morning hours of Thursday, but Thursday is expected to be mainly dry. A cold pool at 500mb should generate some cumulus clouds during the day Thursday, but overall, a clearing trend is expected.

Winds will be breezy during the day Thursday, but are expected to be much weaker than Wednesday; generally gusting less than 15 kt. Thursday is shaping up to be a relatively nice day, with highs in the 70s to near 80, warmest in the CT River Valley, southeast MA, and Rhode Island.

Thursday evening is shaping up to be the coolest night for the foreseeable future. Dewpoints in the 50s, light winds, and clearing skies should allow for radiational cooling. Widespread 50s are expected, with urban heat islands being the exception; metropolitan areas such as Hartford and Boston will remain in the 60s. The Cape will also fall back into the 60s given the warm SSTs and slightly higher dewpoints.

LONG TERM /FRIDAY THROUGH TUESDAY/. Highlights .

* Dry with Summer-Like Warmth Fri & Sat, but humidity will remain comfortable for August standards

* Increasing humidity during the first half of next week with the best chance for scattered showers and a few t-storms Tue into Wed

Details .

Friday and Saturday .

Upper trough over the Northeast pulls away from the region as Bermuda High pressure strengthens. This will result in summer-like warmth with above normal temperatures Fri & Sat. High should be well up into the 80s to near 90. Humidity levels will remain comfortable for August standards despite the very warm weather. Upper level ridging should also result in dry weather along with plenty of sunshine.

Sunday through Wednesday .

The focus will be on shortwave energy across the Great Lakes on Sunday and when it moves east. Upper level ridging over the Atlantic coupled with confluent flow across Northern New England may keep our weather mainly dry Sun and perhaps Mon too. While a surface warm front may trigger a few brief showers sometime Sun into Mon, the lack of deeper synoptic forcing may result in generally dry weather. A better chance for some showers and a few t-storms will be sometime Tue into Wed as better shortwave energy approaches from the west.

High temps will mainly be in the 80s over this time with the warmest day expected to be Sunday when a few spots may approach 90 across the interior. The bigger story will be the increasing humidity; so it will certainly feel summer-like over this timeframe.

AVIATION /07Z WEDNESDAY THROUGH SUNDAY/. Forecaster Confidence Levels:

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

06z TAF Update .

Mainly VFR but MVFR and potentially IFR conditions will develop across terminals on the Cape and Islands. -SHRA/-RA coverage increases from east to west Wednesday morning before gradually tapering off from south to north Wed afternoon. Northeast winds will become gusty near sunrise. Winds generally 20-25 kt but will gust up to 40 kt at Nantucket. Winds gradually shift from the NE to the W as low pressure departs for the gulf of Maine late in the day Wednesday.

Wednesday . Moderate Confidence.

Increasing chances for -RA/-SHRA from east to west, with higher confidence in precipitation at eastern terminals. VFR for western terminals but MVFR and IFR conditions possible as low ceilings develop across eastern zones, especially across Cape Cod and the Islands. N/NE winds will be gusty; up to 25 kt along the eastern MA Coast, including BOS. Winds may gust to 40 kt at ACK Wednesday morning before tapering off in the afternoon.

Wednesday Night . Moderate Confidence.

Mixture of VFR and MVFR/IFR conditions with -RA across northeast MA terminals. CIGS rise overnight to VFR for all terminals. Winds becomes NW 5 to 10 kt.

Thursday . High Confidence.

Mainly VFR with conditions improving through the day. Low chance for a shower across interior southern New England Thursday morning. NW winds, gusting to 15 kt, become westerly in the afternoon. Winds will be more from the W/SW on Cape Cod and Nantucket, but still generally less than 15 kt.

KBOS . Moderate confidence in TAF.

KBDL . High confidence in TAF.

Outlook /Friday through Sunday/ .

Friday: VFR. Breezy.

Friday Night through Saturday: VFR.

Saturday Night: Mainly VFR, with local MVFR possible. Slight chance SHRA.

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

MARINE. Forecaster Confidence Levels:

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

Gale Warning for eastern waters and Nantucket Sound through Wednesday afternoon, Small Craft Advisories continues for all other waters through Wednesday night.

Wednesday night into Wednesday Night . Moderate Confidence

Low pressure will track into the gulf of Maine into Wednesday, which will really kick up the seas; with waves up to 11 feet possible. Given these conditions, a high surf advisory has been issued for our eastern facing coastlines for Wednesday. Eastern and southeast waters experience north/northeast gales overnight into Wednesday.

Thursday and Thursday night . High confidence

Winds will gradually shift from the W/NW to W/SW during the day on Thursday as they die back; gusting to about 15 kts. Waves will take some time to calm after low pressure departs, so small craft advisories may need to be extended on the premise of wave heights for our outer waters through the day Thursday.

Outlook /Friday through Sunday/ .

Friday through Saturday: Winds less than 25 kt.

Saturday Night through Sunday: Winds less than 25 kt. Slight chance of rain showers.

BOX WATCHES/WARNINGS/ADVISORIES. CT . None. MA . High Surf Advisory from 8 AM this morning to 8 PM EDT this evening for MAZ007-015-016-019-022-024. Wind Advisory from 6 AM this morning to 3 PM EDT this afternoon for MAZ022-024. RI . None. MARINE . Small Craft Advisory until 8 AM EDT Thursday for ANZ230- 233>237-251-256.
