Area Forecast Discussion National Weather Service Gray ME 923 PM EDT Sat Jun 1 2024

SYNOPSIS
High pressure will build overhead through Sunday with temperatures remaining above seasonal norms and winds diminishing. High pressure will remain overhead early next week...with an increasing marine influence causing temperatures to fall closer to normal for early June. The next chance for widespread rainfall does not arrive until the end of next week.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/
0125Z Update...
Minor edits to the ongoing forecast which continues with dry and mostly clear conditions across the region. Expect mainly some high level cloudiness fromm time to time across the Northeast tonight. Low dew points will allow for another chilly night across much of the region with min temperatures in the 30s in the northern mountains.

Update...Very well defined sea breeze continues to progress to the west through interior southern Maine and New Hampshire per latest radar trends. Some Cu remains just west of this boundary as well.

The sea breeze will dissipate after sunset leaving the forecast area once again under mainly clear skies and light winds. With low surface dew points remaining in place, temperatures will fall rather quickly during the overnight hours, bottoming out in the 30s across the north with mainly 40s elsewhere.

Prev Disc...
High Impact Weather Potential: Minimal.

Pattern: A northerly gradient continues through tonight as mid level ridge axis builds into western New England while a cutoff low sinks south through the Canadian maritimes. This will continue the persistent
dry
northerly flow aloft that has been entrenched over the area for the past few days with little in the way of weather concerns for the overnight.

Through this Evening: Few/Sct clouds over western ME will diminish with the loss of daytime heating while some thin cirrus arriving from the west will allow for a nice sunset. With more of an easterly push this evening...expect 8pm temps to fall into the 50s and lower 60s across ME with temps in NH remaining in the upper 60s to around 70.

Tonight: Llevel gradient will be less than on previous nights despite ongoing northerly flow in the mid and upper levels given the arriving surface high pressure ridge axis. A dry airmass will preclude any lower cloudiness...with just a few high clouds spilling over the mid level ridge as shown in the HRRR
Thus
pretty much ideal radiational cooling conditions and see little reason to stray from the trend of going a bit below the cool end of the statistical guidance which brings the coldest locations to around 40 tonight with most spots falling into the middle 40s to lower 50s.

SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY/
High Impact Weather Potential: Minimal.

Pattern: Northern New England will find itself in somewhat of a col position during the short term as the arriving mid level ridge weakens and we find ourselves between a large troughing towards James bay and a cutoff sitting south of Nova Scotia. Weak surface ridging will be the result with northerly flow in the mid and upper levels continuing...though weaker than in days previous.
Therefore little in the way of sensible wind impacts are expected through the short term forecast period with our focus being largely on temperatures.

Sunday: Quiet weather continues on Sunday with a weak high pressure ridge axis overhead. A few cirrus along with a few flat cu /esp east/ are expected but with lighter winds than on Friday-Saturday.
This will likely be the warmest day of the stretch away from the coast with T8s pushing above 13C across NH and far western ME...dropping a few degrees as you move to the Capitol region and Midcoast. This is roughly 2-3C warmer than on Saturday which should allow highs to push in the the upper 70s to mid 80s from north to south
The exception will be at the coast
where a more robust seabreeze is expected given little in the way of a surface gradient...with readings reaching the upper 60s to mid 70s here.

Sunday Night: Outside of some high cloudiness...a mostly clear and calm might is expected. Dewpoints will be higher than on Saturday night...which will yield lows another step higher than previous nights...likely reaching the upper 40s in the coolest northern valleys...but 50s elsewhere.

Conditions will again likely support a beach hazard statement on Sunday for warm air temperatures and cold water temperatures though a slackening gradient will allow for a bigger sea breeze push on Sunday than on Saturday.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
No significant changes to the long term to what has been advertised the past few days. An upper level ridge to our west will shield the area from any significant precipitation through late next week before a cold front and an upper level low push east by next weekend.

In the dailies: On Monday a weak warm front will try to lift north with a disturbance moving along it. This feature will pass to the of the region early Monday. Meanwhile low pressure east of Nova Scotia will pivot a trough around it. This will halt the northward movement of the warm front and by Tuesday result in a more NE flow. What this means is that Monday will likely be the warmest day of the week with above normal temperatures. The NE flow on Tuesday will cool temperatures some, especially along coastal areas as well as the higher elevations of the interior.
Wednesday into Thursday the upper level ridge will move over the area. This will continue mainly dry weather with seasonable temperatures. Thursday Afternoon through Friday the ridge moves east of the area at which point scattered showers will start to develop...mainly over NH at first then moving east into Maine.
By Saturday the cutoff low that has been slowly drifting east from southern Canada will get close enough to place the region under a cyclonic flow aloft which should enhance the shower potential as we head into next weekend.

Included patchy marine fog along the midcoast Monday Night and Tuesday Night. Added patchy fog over land late each night Wednesday Night through Friday Night as the airmass moistens and showers start to develop.

AVIATION /02Z SUNDAY THROUGH THURSDAY/
Short Term...

Summary: High pressure building overhead today will remain across the region through Sunday night with mostly clear skies and northwest winds /sea breezes at the coast/ weakening through Sunday.

Restrictions: VFR conditions are expected to dominate the period through Sunday night.

Winds: Northwesterly winds 10G15kts inland with sea breezes along the coast with winds going calm/light-variable tonight. West- southwest winds 5-10kts for the day on Sunday with sea-breezes again developing at all coastal terminals.

LLWS: LLWS is note expected through Sunday night.

Lightning: Lightning is not expected through Sunday night.

Long Term...

Generally Expect VFR to MVFR throughout the period. Areas of IFR possible beyond the long term aviation portion of the forecast as we head into Thursday and Friday.

MARINE
Short Term...Winds and waves remain below SCA levels through Sunday night as high pressure builds towards the waters today and remains over the waters Sunday and Sunday night. Onshore southerly flow is expected each afternoon with the development of the seabreeze...with winds turning weakly offshore overnight.

Long Term...Wind and waves to remain below SCA conditions through the extended forecast period. Patchy fog mainly at night starting Monday Night.

GYX WATCHES/WARNINGS/ADVISORIES
ME...None.
NH...None.
MARINE...None.
