Area Forecast Discussion National Weather Service Gray ME 941 PM EDT Sun Jun 16 2024

SYNOPSIS
High pressure will move off the New England coastline tonight, allowing for continued mild temperatures and low humidity. A warm front will move into the region Monday followed by a stretch of very hot and humid conditions through the week. A weak cold front will slowly cross through the region on Thursday and Friday.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/
9:30PM Update...Clouds continue to stream over the region with cloud heights mostly remaining above 10K at this time. Removed any mention of a shower for tonight as low levels are extremely dry. Also trending sky cover up a bit due to thickening mid- level clouds.

6:15PM Update...No real updates needed with the forecast with a quiet Sunday evening expected to continue as some high clouds stream over the region. Expect another cool and dry night, overall limited if any tweaks to the forecast with this update.

High pressure over the Gulf of Maine will slide southeast tonight while a warm front approaches from the west towards Monday morning. A relatively cool and dry airmass in place will allow for temperatures to drop quickly after sunset while increasing clouds with the approaching front will keep temperatures from dropping as low as last night. Lows will generally be in the 50s. The approaching warm front may bring enough forcing for isolated showers towards Monday morning across the mountains toward central Maine.

SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY/
A warm front lifting through the area will maintain slight chances for showers across the north with much of the area seeing mostly cloudy skies to start the day. Cloud cover will thin from SW to NE through the day leading partly to mostly sunny skies in the afternoon. The leading edge of a warm and humid airmass will push into New Hampshire by early afternoon and with clearing skies... highs across New Hampshire will climb into the low to mid 80s. High temperatures will drop off into the low 70s across eastern zones where cloud cover will linger the longest.

Warm air advection will continue into Monday night as high pressure anchors southeast of the Gulf of Maine. Lows Monday night will be in the 60s.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
The extended portion of the forecast starts right off the bat with increased temperatures and humidity values on Tuesday.
Models continue to suggest a large and highly anomalous upper level ridge will build over the Northeast this 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.

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 /02Z MONDAY THROUGH FRIDAY/
Short Term...VFR likely prevails tonight through Monday night.
Clouds increase tonight into Monday morning while cigs look to remain above MVFR thresholds. South winds increase through Monday with gusts 15-20 kts along the coastal plain Monday afternoon.

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 slides SE of the Gulf of Maine tonight and remains centered just SE of the waters through Monday night. South winds will increase Monday with gusts around 20 kts Monday afternoon. There may be a few gusts to 25 kts Monday afternoon, while a stable boundary layer should limit the potential for stronger gusts. Persistent S flow will lead to seas building 4-5 feet Monday afternoon and there is potential an SCA may be needed late Monday into Monday night.

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.
