Area Forecast Discussion National Weather Service Gray ME 941 AM EDT Mon Jun 17 2024

SYNOPSIS
A warm front will move into New England today, which will be followed by a stretch of very hot and humid conditions through the week. Record high temperatures and potentially dangerous heat index values are possible. A weak cold front will slowly cross through the region on Thursday and Friday with an increasing chance for scattered showers and cooler temperatures this weekend.

NEAR TERM /THROUGH TONIGHT/
940 AM...Minor update to reflect observational trends. Much of the precipitation on current radar over the area has yet to reach the ground based on surface obs. There are radar returns upstream over SE Canada that will bring slight chances for showers across the north as moisture increases in the atmospheric column.

640 AM Update... Made some minor adjustments to temperatures and sky cover based on latest trends but the forecast remains largely unchanged. The mid- levels are beginning to moisten (as seen from Mt. Washington RH) and therefore the potential for sprinkles or light showers will continue to increase through mid morning, mainly over the north/mtns.

Previously...
Surface high pressure is located over southeastern Massachusetts early this Monday morning with satellite imagery showing high- altitude clouds continuing to stream into our region while riding along an h5 ridge axis. Northeast radar mosaic is beginning to show some light returns over VT and portions of NH but ASOS reports indicate this activity is simply virga with the 00Z KGYX RAOB report showing significant dry air aloft. This combined with weak forcing for ascent should continue to allow for this activity to evaporate before reaching the ground. It will otherwise continue to be a cool morning with temperatures beginning to warm a bit from earlier readings in response to the increasing cloud cover.

A surface warm front will lift northward over Northern New England today, allowing for increasing WAA aloft. At the surface, winds will be out of the south at around 10-15 mph, which will keep much of the coast into the 60s to around 70 and into the mid-70s inland. Over NH high temperatures will be warmer with readings into the middle 80s but dew points will remain comfortable into the 50s to near 60 degrees. Mainly cloudy skies early will become partly sunny late with a low-end chance for an isolated shower/sprinkle (mainly over interior western ME).

Tonight will feature partly cloudy skies and light winds with dry conditions continuing. Some patchy fog may develop late with low temperatures into the upper 50s to middle 60s.

SHORT TERM /TUESDAY/
The heat and humidity will build on Tuesday under partly cloudy skies. WAA aloft will help to push 925 mb temperatures up to around +25C, and given good mixing this places highs into the lower to middle 90s. The exception will be at the coast where onshore wind will keep temperatures into the 70s and 80s. Dew points will also be increasing into the upper 60s to around 70, which will result in afternoon heat indices into the middle to upper 90s across interior south-central NH and interior southwestern ME. As a result, went ahead and issued a heat advisory, which will run from 12pm to 8pm Tuesday.

Latest CAMS suggest the potential for a few discrete updrafts/thunderstorms to develop during the afternoon/early evening hours. Despite weak bulk shear of around 15-20 kts, there will be high MUCAPE and decent lapse rates and therefore should a storm develop it could become locally strong with gusty winds the primary hazard given inverted-v soundings.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/
Models continue to suggest a large and highly anomalous upper level ridge will build over the Northeast mid-week. A 600 DM 500 mb high is rare for this part of the country, especially considering it is mid June. H8 temperatures near +18C and nearly full sunshine will allow for widespread 90s with a few communities in southern New Hampshire approaching 100 degrees.
Along the coast, cooler temperatures can be expected as winds become onshore during the day.

Wednesday will be a similar day as the H5 high remains parked over the New England coastline. A warm start, nearly full sunshine and H8 temperatures climbing to +20C, expect even warmer temperatures.
Afternoon temperatures will likely approach if not exceed 100 degrees across some interior locations. The atmosphere will once again be modified along and near the coastline where southerly winds bring in cooler temperatures. This inland penetration of this coastal front will not be significant however. A few miles inland and away from the coast will be extremely hot, hazy and humid. Surface dew points will climb into the 65 to 70 degree range.

12Z operational models and ensemble solutions remain with some disagreement with the timing of a passage of a cold front either late Thursday or Thursday night into Friday morning. This has some impact on forecast highs. In general, with a possible delay in the passage of the cold front, the day may be relatively cloud free, at least over central and southern portions of the forecast. Mainly sunny skies and some compressional warming ahead of this weak and broad front may very well lead to the hottest day of the week with readings above 100 degrees across portions of southwest interior Maine and southern New Hampshire. The coast may be cooler once again due to a sea breeze, but high surface dew points will remain in place in all locations.

The excessive heat watch remains in place over interior southern NH and it has been expanded to include interior central NH and portions of interior southwestern ME for Wednesday and Thursday.
Additional heat related products can be expected.

Record high temperatures during the Tuesday through Thursday period may be in jeopardy as shown in the climate section below.
Even Friday will be in the 90s across the interior despite additional cloud cover and scattered showers and thunderstorms with the weak and broad frontal system that will be slowly crossing New England. Overnight lows will be mild as well during the three day stretch which will exacerbate heat related issues.

Note the summit of MWN may reach 70 degrees during the period.

Confidence in the heat wave continues to increase as we head into the week across the interior. Exactly how hot it reaches remains the question. Any clouds from decaying MCSs to our west for example would impact the forecast highs. As mentioned above, onshore winds along the coast may keep things cooler. Will also be monitoring for any potential development of coastal fog during this period as well as inland radiation fog at night and during the morning hours.
However, at this time the gradient flow appears to have a sufficient westerly component to prevent much in the way of maritime moisture from entering the region. Coolest readings, albeit still very warm, will be along the Midcoast region where winds will be onshore.

High pressure nosing into our region from Quebec Province will lead to diminishing heat over the upcoming weekend. Surface winds will switch to a cooler easterly flow. However, despite a 10 to 15 degree drop in daytime highs, it will still be very warm over in New Hampshire and along the Maine border with readings in the 80s.

It will turn mostly cloudy with scattered showers and thunderstorms over the weekend. Low pressure will track out of the Plains Saturday and Sunday leading to the precipitation.

AVIATION /14Z MONDAY THROUGH FRIDAY/
Short Term...VFR conditions will prevail today through at least Tuesday. Light and variable winds early today will become southerly at at 10-15 kts, gusts to around 20kts late this morning through early this evening at KPSM, KPWM, and KRKD due to a sea breeze. There is a low end chance for patchy FG tonight but forecast confidence is low. No LLWS is expected through the period.

Long Term...Mainly VFR conditions through Wednesday followed by more showers and thunderstorms with a cold frontal passage by late Thursday into Friday. Areas of IFR conditions are possible as well during the night time period with patchy valley fog.

MARINE
Short Term...High pressure will remain anchored southeast of the waters through Tuesday. This will result in increasing southerly winds with a few gusts of near 25 kts possible across the outer waters this afternoon through early this evening. Persistent southerly flow will allow seas to gradually increase to 3-5 ft outside of the bays.

Long Term...Winds and seas will primarily be out of the south 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

CLIMATE
Record breaking high temperatures and warm overnight low temperatures are likely Tuesday through Friday of next week.
