Area Forecast Discussion
National Weather Service Gray ME
209 AM EDT Thu May 30 2024

.SYNOPSIS...
-- Changed Discussion --
Low pressure will move along a front to our south this morning,
passing close to the coast of New Hampshire. This feature will
likely provide some shower activity to the coast this morning.
High pressure crosses the region this weekend and builds to the
south early next week. This will provide dry and warmer
conditions.

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
-- Changed Discussion --
Weak low pressure near NYC early this morning will track
northeastward along a stalled out SFC front as the morning and
early afternoon progresses. Weak lift and positive moisture
advection above the SFC front will allow for some of the showers
currently over CT to move northeastward and affect southeastern
NH and portions of coastal Maine this morning into the early
afternoon hours. A few downpours will be possible with a rumble
of thunder or two not out of the question. Away from these
coastal areas, we`ll just deal with some clouds with
temperatures rebounding to near 70F. There will be a short wave
trough moving across the region in the wake of the surface low
this afternoon and this may aid in the development of some
convective showers this afternoon.

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
-- Changed Discussion --
Skies clear out tonight with high pressure moving in. This will
allow for some radiational cooling, especially in the far
interior where some patchy frost will be possible.

Partly to mostly sunny skies are expected on Friday with a fresh
west wind and highs reaching the 70s at many locations.

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
-- Changed Discussion --
Overview: Mainly dry conditions and near seasonable temperatures are
expected through early next week before shower chances increase
towards mid-week as a frontal system approaches from the west.

Impacts: Little to no major weather related impacts are expected.

Forecast Details: Mainly clear skies on Friday night combined
with weak flow may allow for good radiational cooling
conditions. As such, blended in some MOS guidance to overnight
low temperature forecast. This places northern valleys into the
upper 30s with low to middle 40s elsewhere. Some valley fog
could develop overnight as well.

High pressure will continue to build over the area on Saturday and
Saturday night as a weak sfc warm front lifts northward. Saturday
will feature partly to mostly sunny skies and warm high temperatures
into the 70s to near 80 degrees with lows into the 40s to lower 50s.
Temperatures aloft warm some on Sunday with 850 mb temperatures
climbing to around +12C. This combined with afternoon mixing will
allow highs to reach the lower to middle 80s, although cooler along
the coast and mtns. Sunday night will be comfortable with lows into
the 50s. Dry conditions and mild temperatures then look to continue
on Monday and Tuesday before shower chances increase towards the
middle of next week as a frontal boundary approaches from the
west.

Short Term...A period of MVFR cigs are possible this morning at
KMHT/KPSM as low pressure passes to our S. Otherwise, mainly
VFR expected through Friday.

Long Term...VFR conditions will prevail Friday night through
Monday. The exception could be on Friday night into early
Saturday at KHIE and KLEB due to valley nighttime fog. Winds
will be primarily out of the west- northwest at 10-15 kts,
although a sea breeze could develop most days with winds
becoming southerly at KPSM, KPWM, and KRKD.
