Area forecast discussion, Jul 28, 2:48 PM EDT, 25 minutes before
Area Forecast Discussion
National Weather Service Gray ME
248 PM EDT THU JUL 28 2016

.SYNOPSIS...
A weak frontal boundary dropping out of Canada will continue showers
and thunderstorms into the evening. The front slowly slips
offshore on Friday as low pressure track east along the front
offshore of Cape Cod. This will bring another chance of showers
Friday into Friday night. Cooler, more seasonable temperatures
return for the weekend with dry conditions Saturday and another
chance for showers on Sunday into Monday.

&&

.NEAR TERM /TONIGHT/...
A weak front will move south across the region tonight. Scattered
showers and thunderstorms will accompany the front. Some storms
may be be strong but dynamics are not favorable for a sever
weather outbreak. By later in the evening most of the stronger
convection will diminish to just showers. Temperatures will be
warm and muggy tonight as per model guidance.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
On Friday the front becomes stationary to the south with a low/mid
level wave of low pressure developing along the front over the
southern new england coast and moves rapidly east by Friday
evening. Heavy qpf will be associated with this wave to our south
but our forecast area will be far enough north and spared to only
receive .25-.50 inches Friday with the heaviest amounts over
southeast NH. Temperatures will be cooler Friday and Friday night
as cooler air from the north slowly spreads south. Used a blend of
models for pops and temperatures and RFCQPF.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
With active wx across the forecast area this afternoon the
extended forecast will stay close to the previous forecast. Used a
multi-model consensus blend with the previous forecast. Little
change is seen with the latest model guidance...with another round
of showers possible Sun night or Mon...and gradually warming temps
and scattered afternoon showers for the remainder of the week.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
Short Term...MVFR and possible brief ifr conditions tonight
through Friday in scattered showers and even a few possible
thunderstorms. Conditions will improve to vfr Friday night.

Long Term...A period of MVFR conditions is possible in SHRA Sun
night and Mon. Confidence is low on how far N those SHRA
extend...so much of the forecast area may remain dry and VFR.

&&

.MARINE...
Short Term...Conditions to remain below SCA thresholds through
Friday night.

Long Term...Winds and seas are expected to remain below SCA
thresholds.
