Area Forecast Discussion
National Weather Service Gray ME
329 PM EDT Fri Jul 26 2024

.SYNOPSIS...
High pressure will bring drier air along with warm
temperatures this weekend. Areas of smoke aloft may dim the sun
at times. Low pressure may approach the Gulf of Maine early
next week, with unsettled weather moving into the region mid
week. Temperatures remain warm through the period, with
increasing humidity next week.

&&

.NEAR TERM /TONIGHT/...
Breezy conditions today will last into the early evening as
base of trough passes overhead. Other than scattered cu this
afternoon, just a few isolated showers will be possible across
the north and mountains.

The winds and deep mixing have done a good job at keeping the
surface fairly dry through the day. A little RH recovery
expected overnight as temps cool. These should drop well once
winds go calm, resulting in some lows into the lower 50s across
the northern valleys and mid to upper 50s elsewhere. Some fog
will be possible late, but the dry air should keep this to river
valleys which have a bit more moisture.

While some smoke was visible aloft earlier today, there is
additional smoke that may move into and linger in the region
for the weekend. Some indications that light concentrations make
it into the lower levels this evening, which may be apparent on
summits of the higher elevations.

&&

.SHORT TERM /SATURDAY AND SATURDAY NIGHT/...
Ridging builds in for Saturday with weaker flow and temperatures
a few degrees warmer. With lighter winds, expect an afternoon
seabreeze to make its way inland from the coast. Thus temps
along the coast may top out a few degrees cooler tomorrow vs.
today.

Sat night brings a similar setup overnight with few clouds and
light winds. Falling temps overnight may have a quicker start as
winds should slow earlier.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
The extended period start quiet but turns unsettled for much of next
week.  Although no all day rain is expected, chances of showers do
increase.

In the dailies: Sunday will feature high pressure over northern New
England resulting in dry and seasonably warm temperatures. Dewpoints
will be slightly higher than Saturday but not as high as they have
been in recent weeks or will be later next week.

Monday and Tuesday we will be tracking a compressed area of low
pressure both at the surface and aloft that originates over the
western Atlantic.  Models show this system being pulled to the west
nearing south coastal areas which will result in an increase in
shower possibilities later Monday into Tuesday. There is still
uncertainty as to how far west the low makes it and how much
moisture will be drawn in as models show the system weakening as
it approaches the coast. The extra cloud cover from this system
may help keep temperatures down some...but still expect warm
conditions with dew points on the increase resulting in muggy
conditions.

For Wednesday though Friday a warm front will push over area
resulting in a warm and muggy airmass with more chances of showers
and thunderstorms. This is a rather typical mid summer pattern
for New England.


&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
Short Term...VFR. Some restrictions may be possible towards
LEB/HIE for overnight valley fog. Some elevated wildfire smoke
may be present in the region overnight and Saturday, but not
expecting significantly reduced ground visibility at this time.
Winds become calm overnight tonight, and will be lighter
tomorrow outside of a sea breeze affecting coastal terminals Sat
afternoon. This may result in a south wind shift with gusts to
15 kts.

Long Term...
VFR conditions Sunday into Monday give way to MVFR with areas
of IFR in scattered showers Monday Afternoon and Tuesday. Areas
of fog may develop Monday Night.

&&

.MARINE...
Short Term...SW winds become S into Saturday as high pressure
moves south of the region. Conditions remain below SCA criteria,
but will tend to become breeze during the day and lighter
overnight. Waves 1 to 3 ft.

Long Term...
In general wind and waves to remain below SCA levels through
Monday. There could be a period of SCA winds and waves Tuesday
and Wednesday as a southerly flow increases. Expect showers and
areas of fog to develop late Monday through Wednesday. &&
