Area Forecast Discussion National Weather Service Gray ME 950 AM EDT Tue Jun 18 2024

SYNOPSIS
High pressure will settle east of New England through much of this week, setting the stage for hot and humid conditions.
Record high temperatures and potentially dangerous heat index values are likely. A weak cold front will slowly cross through the region on Thursday and Friday with an increasing chance for scattered thunderstorms and cooler temperatures by this weekend.

NEAR TERM /UNTIL 7 PM THIS EVENING/
Update...
Mainly high cloudiness continues to cross much of the forecast area produced by convection upstream over Upstate New York.
Nevertheless, temperatures have turned the corner and remain much warmer than they were 24 hours ago. Conditions in Maine as of 14Z remain mostly sunny with temperatures in the lower 80s in many cases. Across New Hampshire, readings were already in the mid to upper 80s.

A heat advisory remains in effect for interior locations today where widespread lower to middle 90s will combine with increasing surface dew points for hazy, hot and humid conditions.

Thunderstorms with strong gusty winds remain possible over northern areas as well with high DCAPE values per latest soundings. Please note, SPC has expanded the region of Marginal Risk of severe thunderstorms to northern portions of our forecast area. Will place enhanced wording in the forecast for this region for this afternoon and early evening.

630 AM Update... Minor changes to reflect latest observational trends.

Previously...
Nighttime microphysics satellite imagery early this morning shows high level clouds continuing to stream from north to south over western ME with a decaying MCS moving eastward over Quebec. These clouds are riding along an h5 ridge axis that continues to build over New England. Current temperatures are primarily into the upper 50s and middle 60s but a few urban locations remain in the upper 60s and even lower 70s.
Temperatures will remain nearly steady through daybreak.

Surface high pressure will build to our east today as the h5 ridge axis moves overhead, allowing for strong WAA aloft. This will help to boost 925 mb temperatures up to around +25C today.
This places highs into the upper 80s to lower 90s across interior western ME with lower to middle 90s in much of NH. The exception will be at the coast as increasing southerly flow will keep temperatures into the cool 60s and 70s. The latest HRRR does suggest high-level clouds could stick around for a good portion of the day over western ME, which would keep highs a few degrees cooler. Dew points during peak heating will be into the 60s to near 70 degrees, which will help to push heat indices up to around 95 degrees for a few hours. The existing heat advisory remains in effect for the interior south of the mountains.

Latest CAMS continue to indicate the potential for a few late afternoon and early evening thunderstorms over the interior.
While coverage is expected to be spotty, any thunderstorm will be capable of producing locally strong gusty winds given inverted-v soundings. Bulk shear will be light (~15 kts) and this combined with the warm airmass should prevent much of a hail threat both today and tomorrow.

Any lingering thunderstorms will end by around 10pm this evening with partly cloudy skies prevailing. It will be a warm and muggy night with lows into the upper 60s but urban centers will likely remain in the 70s.

SHORT TERM /7 PM THIS EVENING THROUGH 6 PM WEDNESDAY/
High pressure and upper level ridging will remain in control on Wednesday, resulting in another hot and humid day. Skies will be partly cloudy with the potential for additional afternoon showers and thunderstorms. Any thunderstorm will once again be capable of producing locally gusty winds along with briefly heavy rainfall.

High temperatures will be similar to those of today, with readings into the lower to middle 90s across the interior. A few spots could reach the upper 90s provided adequate sunshine and a lack of rain. One notable change will be that most coastal locations will reach the middle to upper 80s as sfc winds become more southwesterly. The exception will be the mid-coast which will remain on the cooler side. Afternoon dew points into the upper 60s/low 70s will help to push heat indices into the 95-100 degree range across the interior with some readings nearing 105.
Along the coast, heat indices could approach 95 except for the mid-coast. The existing excessive heat watch remains in effect and additional heat headlines can be expected.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/
Wednesday nighttime lows will be on the warm side again, mainly in the lower 70s. This will cause cumulative heat stress.

The peak of the heat will arrive on Thursday as a strong upper level ridge remains centered near Long Island New York. After a warm night with patchy fog, temperatures will soar once again under a light westerly flow aloft. Widespread mid to upper 90s can be expected with a few communities, mainly in southern New Hampshire exceeding 100 degrees. Relatively high dew point values will allow for apparent temperatures to climb into the 100 to 105 degree range, very near to the Excessive Heat Thresholds. Scattered showers and thunderstorms will once again rotate around the periphery of the ridge and mainly be centered over northern areas.

A weak front will then be draped over the region on Friday. It will be about 10 degrees cooler than on Thursday, mainly due to the increased cloud cover and the scattered showers and storms across the forecast area. Slightly lower dew points can be expected which will be an ongoing trend into the weekend. A nearly stationary front will allow for scattered showers and thunderstorms throughout the weekend.

AVIATION /14Z TUESDAY THROUGH SATURDAY/
Short Term...VFR conditions will prevail today through at least Wednesday. Patchy FG is possible at times at night, which could result in localized restrictions. There is also the potential for a scattered TSRA from roughly 18Z-02Z today and again on Wednesday. The greatest potential for this is at KHIE, KLEB, and KAUG. Light and variable winds early today will become southerly at KPSM, KPWM, and KRKD behind a sea breeze. Winds will become southwesterly on Wednesday. No LLWS is expected outside of any TSRA.

Long Term...Additional scattered showers and thunderstorms are likely with a cold frontal passage by late Thursday into Friday with possible restrictions. Areas of IFR conditions are possible as well during the night time period with patchy valley fog and associated with more scattered showers and thunderstorms throughout the weekend.

MARINE
Short Term...A few southerly wind gusts across the outer waters could approach 25 kts today and again on Wednesday out of the southwest but winds will largely remain below SCA thresholds.
Seas will be at 2-4 ft.

Long Term...Winds and seas will primarily be out of the south- southwest during the extended portion of the forecast and below SCA thresholds. Highest wind gusts likely will be during the afternoon hours as the sea breeze attempts to form. The winds will briefly become westerly on Friday.

CLIMATE
Record breaking high temperatures and warm overnight low temperatures are likely today through Friday.
