Synopsis for stonington me to merrimack river ma out to 25 nm.. North winds and southeast swell both continue to diminish tonight as high pressure builds over the region. High pressure will dominate our weather through midweek before a cold front begins to approach. That front may bring gusty winds and increasing seas to the waters again by Thursday or Friday.

Area Forecast Discussion National Weather Service Gray ME 1017 PM EDT Sun Sep 19 2021
SYNOPSIS. High pressure will result in continued tranquil weather through Wednesday with near seasonable temperatures. An area of low pressure and associated frontal boundary will begin to approach New England by Thursday, bringing increased cloud cover and scattered showers through at least Friday and possibly the upcoming weekend.
NEAR TERM /TONIGHT/. 1015PM UPDATE . Temperatures seem largely on track with the forecast at this point in the night, although we did update the forecast to tie in the temperature trend with the latest observations. No significant changes in forecast thinking.
7PM UPDATE . High pressure settles into the area tonight providing an ideal radiational cooling set up overnight. Not a cloud in the sky should allow for full cooling potential near ground level. For lows we turn to the low level moisture as a guide, with afternoon observed dewpoints a fair representation of this. This suggests many areas will fall into the low to mid 40s, with the colder valleys able to crater even below this into the mid 30s. As the temperature drops through the dewpoint, that low level moisture will have to either condense into fog or be deposited as dew or frost. Low level moisture profile is all above freezing, so it seems likely that fog will be the answer tonight with valley locations seeing dense fog by morning. Made some adjustments to overnight temperatures based on these ideas. Gave more consideration to a Frost Advisory, although considering the likelihood of fog formation, frost seems less likely and this is what neighboring offices have decided as well. However, we did include the mention of patchy frost in the gridded forecast.
ORIGINAL DISCUSSION . Surface ridge settles overhead tonight. Temps aloft will have warmed a few degrees from last night . but that will be compensated for by ideal radiational cooling conditions. I have gone several degrees cooler than last night . with Nrn valleys dropping into the mid to upper 30s. Should see plenty of fog to prevent temps from getting much cooler than that. I do think there will be patchy frost in some of these valleys . but perhaps not widespread enough for an advisory. Regardless it will be one of the coolest nights of the season so far.
SHORT TERM /MONDAY THROUGH MONDAY NIGHT/. High pressure remains in control Mon and Mon night. Temps will be pleasant during a mostly sunny day Mon . with widespread 70s. Overnight return flow will ensure temps are warmer than tonight . but still a little bit cooler than normal. I also expect valley fog to form again as ridge axis remains nearby and leaves remain on the trees.
LONG TERM /TUESDAY THROUGH SUNDAY/. Overview: A highly amplified upper-level pattern will allow for continued pleasant conditions on Tuesday before the combination of increasing onshore flow and an approaching frontal boundary brings a return to unsettled weather mid to late week. Temperatures will remain near to slightly above average.
Impacts: An approaching frontal boundary combined with increasing PWATS may result in a period of moderate to locally heavy rainfall on Thursday night and Friday.
Forecast Details: Strong ridging/high pressure will allow for another pleasant day on Tuesday as high temperatures reach the upper 60s to lower 70s from north to south under mostly sunny skies. This area of high pressure will then begin to shift east on Tuesday night and Wednesday, which will result in increasing onshore flow. Therefore, expecting clouds to gradually increase late Tuesday night through a good portion of Wednesday and given this pattern some drizzle may also occur, especially along the coast. High temperatures on Wednesday will generally be very similar to those of Tuesday with most areas reaching the lower 70s outside of the mountains.
A frontal boundary associated with a closed low to our west will then begin to approach on Thursday, which will result in additional clouds and provide a chance for scattered showers, especially during the afternoon and evening. The forecast then becomes a little more uncertain as there remains differences between deterministic and ensemble guidance as to the amplitude and placement of a deep trough that will be moving east towards New England. The ECMWF is generally more amplified and less progressive than the GFS, and keeps us under a troughing pattern through the upcoming weekend. Taking a look at ensemble guidance, most individual members are favoring the best chance of rainfall to occur Thursday night through Friday. Ensemble guidance is also suggesting that PWATs will increase to >=1.00" during this period, which combined with some added forcing for ascent from the front, could result in a period of locally moderate to heavy rainfall. Beyond Thursday, there remains a large amount of spread between forecast guidance as to how quickly this front and associated unsettled weather will exit the region. Some models such as the CMC and ECMWF stall the system over New England, which keeps us unsettled through the weekend whereas other guidance is more progressive. Given the blocking pattern, overall sided with the slower solutions and therefore kept a chance of showers through Sunday for the majority of the forecast area.
AVIATION /00Z MONDAY THROUGH FRIDAY/. Short Term . Widespread VFR through Monday. Overnight valley fog will develop at HIE and LEB. I expect similar timing to last night . with fog moving in around 05z and continuing to 13z give or take an hour. Tonight fog may try and work into the Merrimack Valley and CON and MHT. Patchy fog may even work into the coastal terminals . but confidence is too low to include in the TAFs at this time Fog will develop again Monday night. but less widespread . with LEB and HIE having the best chances for LIFR conditions again.
Long Term . High pressure overhead will result in VFR conditions on Tuesday. This area of high pressure will then shift east across the waters on Wednesday, resulting in onshore flow and the development of MVFR ceilings and perhaps even drizzle, especially across coastal terminals. A frontal system will then arrive by Thursday, possibly lasting through the weekend with periods of showers likely, resulting in MVFR/IFR conditions at times.
MARINE. Short Term . Swell from Odette continues to slowly diminish. Seas are down to 4 ft every 10 sec . and wind gusts are below 20 kt . so I have cancelled the SCA. High pressure will dominate the waters Mon and Mon night with light winds and small seas.
Long Term . High pressure will allow winds and seas to remain below SCA criteria on Tuesday and Wednesday. Southerly winds may approach criteria on Thursday and Friday ahead of an approaching cold front.
