Area Forecast Discussion
National Weather Service Gray ME
559 AM EDT Sat Jun 1 2024

.SYNOPSIS...
High pressure over the Great Lakes will settle off the east coast
bringing and extended stretch of dry weather to the region with
temperatures gradually warming through the weekend. Cooling
seabreezes will form on the coast today through at least
Monday. The first half of next week is expected to continue the
dry and mild stretch with unsettled weather possibly to return
late next week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
6 AM Update...No changes to the going forecast. We are on track
for a beautiful morning weatherwise.

Previously...

High pressure gradually builds overhead this weekend while weak
low pressure continues to spin over the Maritimes. This will
continue to the northerly or northwesterly flow regime with warm
temperatures with wind gusts 15 to 20 MPH. A late day seabreeze
is expected on the coast which will make it feel quite
chilly/cold there by 00z this evening. Otherwise, dry weather is
expected under mostly sunny skies.

Beach hazard statement continues for sunny/mild/breezy
conditions with ocean temperatures still in the 50s. Fully
expect these headlines will be necessary through the weekend
given continued dry and mild conditions.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
No changes with the forecast for tonight. Mostly clear skies
expected with deep layer ridging moving overhead. Went with a
blend of MOS products for lows tonight as radiational cooling
will likely be quite good, especially across northern NH.
However, the air mass has modified enough that frost
development should not occur.

Another fair and warm day expected on Sunday with highs around
80 except on the immediate coast where a seabreeze will likely
form and make it chilly by late in the afternoon.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
A rather quiet weather pattern continues in the long term. An
upper level ridge will shield the area from any significant
precipitation through most of next week.

In the dailies: An area of mid and upper level clouds may cross
the area Monday with spot showers possible in the north. Behind
this the east coast ridge builds back north and should dominate
the weather through midweek. Can`t rule out some scattered
diurnal shower activity mainly over the mountains and foothills
but most of the time conditions should remain dry. A cutoff low
over southern Canada just north of the Great Lakes will have a
hard time making eastward progress. A cold front pivoting around
this system will approach Thursday and Friday increasing the
chances of showers and possibly a few thunderstorms. The GFS is
more aggressive than the ECMWF with this frontal feature. Given
that we are in a rather blocky pattern, would favor a littler
slower progression with this system so will go under GFS POPS
and trend a little closer the the ECMWF. Have added patchy
marine fog each night Monday Night through Wednesday Night.

Temperatures will be on the warm side reaching somewhat above normal
values ranging from the upper 70`s to mid 80`s Monday and mid
70`s to low 80`s Tuesday through Friday. Expect afternoon
seabreezes to cool the immediate coastal areas and islands. Low
temperatures will generally be in 50`s.

&&

.AVIATION /10Z SATURDAY THROUGH WEDNESDAY/...
Short Term...VFR conditions expected today. Northwest to north
winds will again build to 10g20kts by late morning and through
the afternoon before going calm/light- variable tonight. A
seabreeze is expected at coastal terminals by late afternoon
today and again on Sunday.

Long Term...

Generally Expect VFR to MVFR throughout the Monday-Wed period.

&&

.MARINE...
Short Term...With high pressure west of the region
northwesterly winds of 10-15kts are expected to continue through
the period with nearshore gusts 20kts at times. Winds will go
onshore this afternoon and Sunday afternoon as a seabreeze
develops each day.

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...Beach Hazards Statement through this evening for MEZ023>028.
NH...Beach Hazards Statement through this evening for NHZ014.
