941 am edt Thu aug 22 2019

Synopsis
A cold front will sweep across the region today accompanied by
scattered showers and thunderstorms. A few thunderstorms could
contain strong gusty winds. Cooler and less humid air follows
the front beginning tonight. High pressure will gradually build
in over the weekend and early next week allowing for an extended
stretch of quiet weather.

Near term until 6 pm this evening
930am ... Adjusted current temperatures and cloud cover. Some
low clouds hanging on in the midcoast, but expect them to
continue to erode. For the afternoon increased the pop slightly.

Expecting a line of showers and thunderstorms to move through
which will impact most areas for a brief period of time.

605 am... Minor estf update to reflect the current mesonet in
near term grids.

Prev disc...

at 06z... A 1003 millibar low was over quebec with a wavy warm
front through northern new england and a trailing cold front
through the lower great lakes. NWS doppler radar mosaic showed
scattered convection occuring along and ahead of the boundary.

Widespread stratus and fog had formed across much of the area
and should gradually lift and mix out as the warm front pushes
to our north in a strengthening southerly flow ahead of the cold
front. Sunny periods and southerly flow should warm temperatures
into the lower and mid 80s across much of the area ahead of the
cold front. Dew points in the 60s and lower 70s combined with
forecast high temperatures should yield capes between 1000 and
1500 j kg. Modified forecast soundings support a few broken line
segments with strong wind gusts the primary threat with late
morning and afternoon convection. By early evening the front and
much of the convection will have exited the coast.

Short term 6 pm this evening through 6 pm Friday
For tonight... The front will be just offshore and a weak wave
traveling along the boundary. This will slow post-frontal
clearing along the coastal plain and could brush seacoast new
hampshire and southwest coastal maine with a few showers
overnight. Elsewhere... A partly cloudy night with patchy valley
fog and stratus developing in the predawn hours. On Friday... The
front pushes well offshore with sunshine for the coastal plain
while northern and mountain sections see a few more clouds with
the upper trough and a passing impulse. Comfortable dew points
and a westerly breeze will make for a fall-like feel as high
temperatures are limited to near 70 in the mountains and in the
70s elsewhere.

Long term Friday night through Wednesday
In the long term high pressure will build overhead keeping the
forecast area under rather pleasant conditions. However by
Sunday models are showing an upper level closed low developing
and moving slowly northeast Sunday through early Tuesday. The
overall position of this closed low will ultimately determine
the location of afternoon clouds and showers for Sunday and
Monday. I have a 20 to 30 pop over the southern half of the
forecast area for Sunday into early Monday. The chance for
showers could linger into Monday afternoon or even early Tuesday
depending on how fast the low departs. For now think the best
chance for any widely scattered shower will be Sunday. Other
than this the long term looks cooler than normal Saturday
through Tuesday then above normal Wednesday and Thursday.

Dewpoints start to rise Wednesday as does the chance for
precipitation as a cold front approaches the area.

Aviation 14z Thursday through Monday
Short term through Friday ... Areas of ifr and lifr through 12z
in stratus and fog. ThenVFR with sct MVFR developing in
-shra -tsra ahead of a cold front. Sct MVFR tonight in CIGS with
lcl ifr in valley stratus and fog. Improving toVFR throughout
aft 12z Friday.

Long term... MostlyVFR.

Marine
Short term through Friday ... Winds will pick up later today and
this evening with the cold frontal passage but both seas and
wind gusts should remain below SCA threshold.

Long term... Winds and seas should remain below SCA criteria.

Gyx watches warnings advisories
Me... None.
