Area Forecast Discussion National Weather Service Gray ME 1037 PM EDT Sat Jun 15 2024

SYNOPSIS
Behind a departed cold front an area of high pressure will settle over the region through Sunday, bringing mild and less humid conditions for the weekend. A warm front will move into the region Monday followed by a stretch of very hot and humid conditions through the week.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/
1030 PM Update...No changes to the going forecast. Temperatures and winds are on track. Will continue mention of patchy frost in the north.

650 PM Update...Little change to the going forecast as a clear evening with diminishing winds are expected.

Previously...

High pressure centered over Ontario will gradually build in tonight and will crest over the area Sunday morning. Breezy NNW winds will relax later this evening and will go close to calm tonight, especially in valley locations. The combination of clear skies and calm winds will allow for efficient radiational cooling. The forecast challenge for tonight will be how cold do northern valleys get and the potential for patchy frost.
Currently dewpoints in northern valleys are near 40F and 32F on Mt Washington suggesting this is the floor for lows. Have utilized MOS guidance for lows which does bring lows into the mid to upper 30s across northern zones and into the 40s south of the mountains. Have included patchy front is the forecast in Coos County, while areal coverage too limited for a Frost Advisory, although will watch trends if temperatures trend cooler.

SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY/
High pressure centered over the area Sunday morning will slide southeast offshore Sunday afternoon. Skies will start off mostly clear with some cirrus moving in from the west Sunday afternoon.
Highs will generally be in the mid to upper 70s across the interior with low 70s across the north and near the coast where winds turn onshore.

Mid to high level clouds increase Sunday night ahead of an approaching warm front. Showers associated with the front will likely hold off until Monday morning. Lows will not be as cold as tonight and will generally be in the 50s.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
*** The heat is on as potentially record breaking temperatures arrive for the start of summer ***

Here are the records...

RECORD HIGHS FOR JUNE 19: Concord-98, 1995 Augusta-98, 1995 Portland-94, 1995

RECORD HIGHS FOR JUNE 20: Concord-98, 1993 Augusta-95, 1953 Portland-93, 2020

We begin the extended with a tale of two climates on Monday. A strong warm front will be draped over the region. East of this front, chilly conditions will continue across much of the Midcoast region of Maine with highs only in the 60s. The remainder of the state will be seasonably warm with highs in the 70s. Across western York County and much of New Hampshire, the warm front is expected to pass through with temperatures reaching the lower to mid 80s.

This strong warm front with rapid height rises and the possibility of a short wave rounding the top periphery of the ridge may trigger a few showers and storms on Monday. In fact, this type of set up has the potential for a fast moving MCS to round the ridge. While this is not a likely scenario, it should be considered.

In any case, remarkable height rises continue on Tuesday across the Northeast. This is rare for June and with height rises approaching 600 dm at 500 mb over New York City, this anomaly is particularly significant as we are still in the middle of the month. The Euro ensemble suggests a 45 to 50 percent chance of heights greater than 597 DM at WFO GYX. The highest 500 mb height ever measure at GYX (by our balloon launch sounding) was 598 DM set on July 5th in 2018.

In any case, widespread 90s can be expected across the region with the highest readings over southern New Hampshire.

It is important to note that along and near the coastline a cooling sea breeze will form. In fact, temperatures may hold in the 70s to lower 80s for highs along the beaches and peninsulas as a south to southeast onshore breeze develops.

Surface dew points will be on the increase as well. Expect this moisture to climb and reach the mid to upper 60s. There remains some drier air aloft to mix down per latest Bufkit soundings.
Mixing levels may reach 7K feet. This moisture will allow for patchy overnight fog to develop across portions of the region.

The large dome, an upper level ridge will be parked over the Northeast again on Wednesday. Guidance has trended warmer for this day including the coastline where temperatures will climb rapidly through the 80s despite a sea breeze. Across the interior, widespread 90s expected with a few communities over southern New Hampshire flirting with 100 degrees.

PWATS will be increasing with surface dew points remaining between 65 and 70. This will allow for maritime fog to likely form over the cold Gulf of Maine water temperatures. However, with a west to southwesterly flow aloft, this fog should remain offshore. This flow will be weak however with the forecast 18Z winds at MWN expected to be 260 degrees at 16 knots. A warm night will follow with 60s and lower 70s for overnight lows.

Thursday will be a repeat day with hazy, hot and humid conditions. Compressional warming ahead of an approaching cold front may balance out increasing clouds to determine the expected forecast highs. Nevertheless, widespread 90s and possibly low 100s remain plausible. A few late afternoon showers and thunderstorms may develop along the front, mainly over central and northern areas.

It will be slight less hot on Friday. Never the less, hazy, hot and humid conditions will end out the work week and into Saturday.

AVIATION /03Z SUNDAY THROUGH THURSDAY/
Short Term...VFR will prevail tonight through Sunday night. NNW winds will relax this evening becoming light and variable tonight. A sea breeze likely develops Sunday bringing onshore winds into coastal TAF sites.

Long Term...IFR conditions developing in scattered showers and thunderstorms on Monday. Otherwise, mainly VFR conditions through Wednesday followed by more showers and thunderstorms with a cold frontal passage on Thursday. Areas of IFR conditions as well during the night time period with patchy valley fog.

MARINE
Short Term...High pressure builds in from west tonight and crosses over the waters Sunday into Sunday night. NW to N winds will prevail into tonight and then shift onshore Sunday. Winds and seas will remain below SCA thresholds while waves may approach 4-5 at the outer fridge of offshore zones.

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.
