Area forecast discussion
National Weather Service Gray ME
303 am EDT Wednesday Sep 2 2015
a weak cold front will approach from the north today and will
gradually settle south through the region tonight and Thursday.
High pressure will build south from Canada Thursday night through
Friday. High pressure will crest over the area Friday night and
will push south off the coast on Saturday. High pressure will hold
south of New England Sunday through Tuesday.
Near term /through today/...
quiet weather continues today as high pressure remains anchored
south of New England. Should be a hot one in interior sections of
Maine and New Hampshire with highs topping out in the middle 80s to
near 90. Once again an afternoon sea breeze will cap temperatures at the
coast in the upper 70s to middle 80s.
Short term /tonight through 6 PM Thursday/...
weak cold front will drop south from Canada overnight bringing
variable high and middle level cloudiness into the forecast area
overnight. Will see a warm night for this time of year with lows
ranging through the 60s in most locations.
Cold front will linger over southern zones on Thursday before
shifting offshore in the evening. Some fairly respectable convective available potential energy
develop during the afternoon in southern and central zones so
expect showers and thunderstorms to develop from late morning
Onward. Not a lot of shear so not looking for any widespread
severe but pwat's approaching 1.5 inches and slow storm movement
will provide some much needed rainfall for southern New Hampshire
and Maine. Expect highs to range through the 80s from north to
Long term /Thursday night through Tuesday/...
cold front will continue to drop well to our south Thursday
evening ushering a cooler and drier airmass. Any showers or
thunderstorms across southern zones will end early in the evening.
Thereafter...high pressure will settle in through Saturday...then
settle to the south of the area Sunday through early next week.
After a brief cool down for Friday into Saturday...return flow
around high pressure for Sunday through Tuesday will result in
increasing heat and humidity once again. At this time...it looks
as though Monday and Tuesday should feature temperatures 85 to 90
for most...and possibly as high as the 92 to 94 range at a few
spots across southernmost zones. Summer is not leaving US yet. Dry
weather is currently expected through much of the extended after
whatever showers/storms end Thursday evening.
Aviation /06z Wednesday through Sunday/...
short term...VFR today through Thursday. Areas of IFR/LIFR
ceilings/visibility in morning valley fog Thursday.
Long term...mainly VFR conditions are expected Thursday night through
Sunday. A period of lower conditions is possible Thursday evening in
short term...no flags.
Long term...northeasterly winds are expected to increase Thursday
night in the wake of a cold front. Small craft conditions will be
possible then. Otherwise...no significant issues foreseen.
