Area Forecast Discussion
National Weather Service Gray ME
319 AM EDT FRI JUL 1 2016
A cold front will approach from the west today and will cross the
region overnight. A trough of low pressure will linger over the
region Saturday and Sunday. High pressure will build in from the
west Sunday night through Tuesday and will shift offshore on
.NEAR TERM /THROUGH TODAY/...
Cold front will approach from the west today as a strong shortwave
shifts east from the great lakes. Timing of the front will
preclude any severe storms in the forecast area as sufficient
moisture and instability won`t make it into western zones until
late this afternoon and early this evening past the time of max
heating. Will likely see remnants of stronger convection to the
west getting into the connecticut valley by mid afternoon and
spreading eastward across New Hampshire through early evening.
Brisk onshore flow will contribute to a robust marine layer in
southern Maine and southeast New Hampshire so expect convection to
diminish as it pushes into these areas during the late afternoon
and evening. Mountains and foothills of Maine will likely see
enough moisture and instability to get in on some spotty
thunderstorm activity during the late afternoon and evening. High
temps will be similar to Thursdays with most areas reaching the
lower to mid 80s.
.SHORT TERM /TONIGHT THROUGH 6 PM SATURDAY/...
Showers and thunderstorms will gradually push east of the forecast
area after midnight as the front slowly crosses the area. Behind
the front...westerly flow will bring clearing to the region toward
daybreak. Should see a fairly mild night with lows generally in
the mid 50s north to lower 60s south.
Saturday will feature a mix of sun and clouds in the mountains and
mostly sunny skies elsewhere as cooler and less humid air flows
into the region on increasing westerly winds. Highs will range
from the mid 60s to mid 70s north and upper 70s to lower 80s
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Fairly decent weather with mostly dry conditions in the long term
and increasing warmth. For Saturday night and Sunday expect
temperatures to be running cooler than normal. Can`t rule out an
isolated shower in the mountains Sunday afternoon. Temperatures
begin to warm Monday and by midweek the 500 ridge moves in with
temperatures rising into the mid and upper 80s in southern New
Hampshire and lower to mid 80s in southern Maine. A seabreeze will
develop keeping coastal communities a bit cooler.
.AVIATION /07Z FRIDAY THROUGH TUESDAY/...
Short Term...VFR today with areas of MVFR ceilings and vsby in
afternoon thunderstorms across New Hampshire. Areas of IFR/LIFR
ceilings/vsby overnight...especiallly in coastal and southern
interior Maine. VFR saturday.
Expect VFR through the period.
Short Term...No flags.
Long Term...Expect winds and seas to remain below SCA criteria.
