Synopsis
Surface high pressure will remain over the region into Monday while
multiple upper level disturbances move across the state this weekend.

A weak cold front will move through late Monday followed by weak
high pressure for Tuesday. A stronger cold front is expected
late Wednesday night and Thursday.

Near term through tonight
12pm edt update... The primary weather influence through Sunday
is the large high offshore pumping moist marine air northward
under an inversion. This is producing low clouds and reduced
temperatures today, areas of fog tonight, and more low clouds
into Sunday morning. The first of two shortwaves affecting the
area is currently moving across the area. It's weakening and
will be moving out of northern zones in the next two hours or so.

Don't expect enough clearing in western zones to support any
sbcape this afternoon and will not mention thunder until tonight
with a more potent second shortwave currently in the eastern
great lakes region. Most of the activity with the second
shortwave will occur after midnight in this forecast area and
linger into early Sunday morning. This feature could drop
locally heavy rainfall. As it departs in the morning, it'll
leave behind dew points in the mid 60s and Sunday afternoon
temps will rise into the mid to upper 70s as the inversion's
hold breaks somewhat. The inversion and low clouds will persist
on the coast for Sunday.

Previous discussion...

broad cyclonic flow aloft will advect two shortwave troughs
over the state today, which will bring scattered showers and
maybe a few isolated thunderstorms. At the surface the flow will
be out of the south as a surface ridge remains centered just to
the east over halifax. This is allowing for a persistent
southerly push moving a higher dewpoint airmass in the low 60s
over the cold gulf of maine waters. The end result is a
persistent marine layer push through the next 24 hours bringing
with it low stratus and fog to downeast and the penobscot
valley. Overall this will lead to a cool gloomy day for most of
the area. There could be some breaks in the clouds across the
north, but there will also be more showers across northern maine
this morning as the first shortwave trough moves through. Small
break in shower activity is possible midday today before a
stronger 500mb vort MAX approaches from new york this evening.

This could bring a better chance for showers again tonight
across the entire region and even a few elevated thunderstorms
could be possible with MUCAPE values just high enough. The hrrr
is already hinting at this possibility, so added the mention of
isolated thunder later tonight in the forecast. Overall not the
best Saturday, especially if you are on the coast.

Short term Sunday through Monday night
The short and long terms will be dominated by a progressive
wsw flow alf pattern with fqt S WV systems.

Sun begins with exiting shwrs in the morn, with ptly sunny
skies advcg ewrd from qb prov durg the aftn, reach the nb border
latest. Sun eve will begin fair, then clds will increase late
at ngt as a S WV trof from the great lks apchs. Shwrs and enough
cape for aftn eve tstms is xpctd msly across the N hlf of the
fa as the S WV crosses the rgn. Behind this system, a brief
surge of slightly drier air is xpctd for tue, with albeit warm
aftn hi temps.

Long term Tuesday through Friday
Tue ngt will begin fair, with increasing clds late and a chc of
shwrs alg the coast by erly Wed morn as more humid air begins
to return. The rest of the rgn will see ptly clds skies Wed morn
then mcldy skies Wed aftn eve with shwrs likely alg with sct
tstms. Shwrs will linger across the fa late Wed ngt and perhaps
even into Thu across the fa with longer range models uncertain
about the arrival and passage of a cold front thru the fa durg
this tm. All long rang models agree that the cold front
completely clears SE of the fa by Thu ngt, allowing for sig
cooler and much drier air to enter the fa from cntrl can.

Aviation 18z Saturday through Thursday
Near term: variable weather conditions sums up the aviation
forecast over the next 24 hours with a deep marine layer push
expected to impact kbhb kbgr through tonight with low ifr
conditions. Ceilings could increase a bit this afternoon to ifr
conditions before dropping again tonight. Further north
expecting MVFR conditions today at the aroostook county taf
sites before dropping tonight as lower ceilings are expected to
push in. Scattered rain showers are also expected along with
light southerly winds.

Short term: mainlyVFR and light winds all TAF sites xcpt brief
MVFR ifr in tstms and heavier shwrs Mon aftn eve and wed
aftn eve and patchy ngt fog Sun ngt, Mon ngt, and Wed ngt.

Marine
Near term: seas and winds will remain below SCA conditions with
a persistent light southerly breeze moving a humid airmass over
the cold waters. This will keep low stratus and areas of fog
over the coastal waters through Saturday night. Winds will
generally remain in the 5 to 8kt range as a weak surface high
remains to the east of the region, waves will generally be in
the 2 to 3 foot range.

Short term: no marine hdlns for these ptns of the fcst with
marine fog likely Sun ngt thru Mon ngt and again late Tue ngt
thru Wed ngt. Went with about 80 to 90 percent of ww3 wv
guidance for fcst WV hts for outer mzs and a blend of ww3 nwps
for near shore waters. Spectral WV components consist of a short
srly wind fetch nwrd propagating 5 to 7 sec WV group and a nw
propagating background swell WV group of arnd 10 sec.
