High pressure will build down from the north today and tonight
and crest over the area Sunday into Monday. High pressure will
move to the east on Tuesday. Low pressure will approach on
.NEAR TERM /THROUGH SUNDAY/...
The weather system that brought our rain last night will
continue to move away to the east tonight as high pressure
pushes down from the north. Any cumulus clouds across central
and northern areas will dissipate this evening. Clearing will
continue to push down from the north tonight bringing a mostly
clear sky by morning. A bit of valley fog is possible over far
northern areas closer to the center of the high late tonight.
Otherwise, the northeast gradient should remain strong enough to
prevent fog in most areas overnight. Surface high pressure
building down from the north combined with strong upper level
ridging will bring a sunny and tranquil day on Sunday with
seasonable temperatures across the area.
.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
Quiet and dry weather for the short term, with high and low
temperatures right around normal across the forecast area.
Surface high pressure over the Gaspé Peninsula Sunday night
will provide ample presence to suppress an elongated area of low
pressure off the southern New England coast. Easterly flow
around the high will bring some low level moisture to Downeast
for cloud cover early Monday morning. Clouds will erode with
daytime heating into the mid-to-upper 70s and mostly sunny skies
across the forecast area Monday afternoon. Sky conditions
overnight will remain mostly clear, with temperatures in the
50s and some northern valleys dipping into the mid-40s. Another
dry day Tuesday as high pressure slides northeast. Daytime
temperatures in the upper 70s will be more widespread inland
than Monday, with the Downeast coast remaining mild. High clouds
will move in during the afternoon, continuing to thicken and
lower into the evening. Mid-level return flow winds shift
southerly as a low pressure system approaches from the Great
Lakes Tuesday night.
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Low pressure advancing from the Great Lakes Tuesday night will
pass to the northwest of Maine. This puts the area in likely
chances of rain Wednesday. A few embedded scattered
thunderstorms may form with the passage of the associated cold
front Wednesday afternoon, but have kept them limited to that
period. Storm will exit to the north with precipitation ending
after midnight. Quiet and dry weather returns for the remainder
of the long term, although cooler on Thursday. Temperatures
rebound into the upper 70s heading into the weekend.
.AVIATION /16Z SATURDAY THROUGH WEDNESDAY/...
NEAR TERM: There may be some MVFR conditions Downeast early this
evening. Otherwise VFR conditions are expected across the area
tonight and Sunday.
SHORT TERM: With high pressure over region, expect VFR
conditions Sunday night through Tuesday. IFR/MVFR conditions
for Wednesday as low pressure tracks west of Maine, bringing
widespread clouds and rain.
NEAR TERM: Winds and seas are expected to be below SCA tonight
SHORT TERM: Below SCA conditions for short term. Conditions will
begin to deteriorate Tuesday night into Wednesday ahead of
advancing low pressure traveling northwest of Maine.
