Area forecast discussion, Aug 6, 3:49 PM EDT, 1 hour 58 minutes before
Area Forecast Discussion
National Weather Service Gray ME
349 PM EDT SAT AUG 6 2016

.SYNOPSIS...
A cold front will push offshore this evening. High pressure will
build in from the west Sunday through monday and will shift
offshore on Tuesday. High pressure will hold offshore on
Wednesday through Friday. A cold front will stall near northern
Maine Thursday and Friday.

&&

.NEAR TERM /THROUGH TONIGHT/...
Widely scattered showers and thunderstorms developing across
mainly northern zones will continue to gradually push southeast
through early evening. Capes are rather marginal but increasing
shear could produce some isolated strong to severe cells through
late afternoon with wind damage being the main threat. Expect this
activity to gradually push offshore this evening as the front
pushes through. Looking for just scattered clouds downwind of the
mountains overnight with variable cloudiness in the north. Lows
will bottom out in the lower to mid 50s north and upper 50s to mid
60s south.

&&

.SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/...
Upper trough will cross the region on Sunday as high pressure
builds in from the west. Upslope flow and abundant low level
moisture will keep skies mostly cloudy in the mountains along with
a chance of afternoon showers. Central and southern zones will
see a mix of sun and clouds. Highs will range through the 70s
north and lower to mid 80s south.

Clouds will gradually diminish Sunday night as high pressure
continues to build in from the west. Will see some chilly
overnight lows in northern zones where mountain valleys will dip
into the upper 40s to lower 50s. Lows will range through the 50s
farther south.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
Chance of high impact weather: low, but hot an humid conditions
expected on Thursday.

After weak 500 mb trough exits to the east early in the week the
large ridge to our south builds back in mid to late week. Models
differ with the timing of frontal passage, with the GFS being the
fastest and pushing the front through Thu night, and the 12Z Euro
holding it just n of the CWA through Friday night. So pops at the
end of the period are low confidence but have included slight chc
as early as Wed night, but hitting the chc pops harder later in
the period, more in line with the Euro. This precip at the end of
the week looks to be mostly convective as there is only weak
synoptic forcing with mainly zonal flow aloft, and at this point
scattered showers and thunderstorms look to be the best bet, and
not any widespread rain.

Temperatures will gradually rise each day, Monday through
Wednesday, and start out warm but mostly comfortable Mon/Tue as
humidity stays low. Highs mostly in the upper 70s north to mid 80s
south and overnight lows in the mid to upper 50s north to around
60 in the south. The heat an humidity build Wed and Thursday with
Thursday looking like the hottest day as temps rise to 90-95 in
the warm spots of southern NH and interior SW ME and mid-upper 80s
elsewhere. Fri and Sat highs will be dependent on location of the
cold front.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
Short Term...VFR tonight through Sunday night.

Long Term...Mainly VFR Monday through Thu, with valley fog each
night.

&&

.MARINE...
Short Term...Continuing sca's through 800 pm.

Long Term...Could see W-SW winds approach SCA levels Monday
afternoon, but forecast keep them below 25 kts. Otherwise no
issues through Thursday.

&&

.GYX WATCHES/WARNINGS/ADVISORIES...
ME...None.
NH...None.
MARINE...Small Craft Advisory until 8 PM EDT this evening for ANZ150-
     152-154.
