Synopsis
High pressure will dominate the weather through Sunday with
below seasonal average temperatures expected. Low pressure will
track south of the region Monday into Tuesday. High pressure
will build across the region Wednesday.

Near term through Sunday
945 pm update: latest IR Sat imagery shows a few strands of hi
thin ci crossing NRN and cntrl ptns of the rgn while downeast
ptns of the area are getting brushed with thicker hi cld cvr
movg off the cntrl new eng coast into the gulf of me. Current
hrly fcst cld cvr has this cvrd for our rgn, so no chgs needed
attm. Otherwise, just minor chgs to fcst hrly temps dwpts based
on latest mid to late eve sfc obs with no additional chgs to
fcst ovrngt lows this update.

Orgnl disc: a weak surface trough along the coast will move
offshore this evening and the high will build southeastward from
the james bay region of canada. This is a very cool and dry air
mass with dew points dropping to the 40s across the entire
forecast area by later tonight. H850 temps will be less than 5c
for much of the forecast area by Sunday morning. With light
winds and clear skies tonight, lows will dip into the upper 30s
in some of the normally colder valleys of aroostook county.

Elsewhere in northern zones, lows will be in the lower 40s.

Further south, the cold air won't be quite as firmly entrenched
and some mid- level clouds will move through late in the night.

As a result, lows will only drop to the upper 40s to lower 50s.

The clear skies continue Sunday and temperatures will be a bit
cooler in the southern half of the forecast area than today with
high temperatures forecast to reach the upper 70s. A slack
pressure gradient will permit a sea breeze circulation to
develop along the coast in the afternoon.

Short term Sunday night through Tuesday
Surface high pressure will be ridged north and east of the
region Sunday night through Monday night. At the same time,
surface low pressure will track to the south while an upper
level trof slowly crosses the region. Cloud cover will increase
across the region Sunday night through early Monday. The
surface high will impede and slow the progress of rain across
the forecast area, particularly northern areas. Uncertainty
still exists regarding the placement of precipitation and rain
totals Monday through Monday night. Showers will then diminish
Tuesday with high pressure building across the region during the
afternoon. Temperatures will be at below normal levels
Monday Tuesday.

Long term Tuesday night through Saturday
High pressure will allow for a clear, calm, and cool tues
night, with lows ranging from the lower 50s downeast to the
upper 40s in the north woods. Pleasant weather will continue
through wed. Clouds will begin to overspread the CWA Wed night
as an upper trough and surface cold front approach from the
west, but both the cmc and ECMWF have backed off onset of precip
until after 12z thu, bringing them more in line with the gfs.

There remains some disagreement between models on how much
moisture and thus precip will be associated with this front,
with the ECMWF and cmc both on the wet side, and the gfs
decidely on the dry side. For what it's worth, the GFS has been
much more consistent than the other two models on both frontal
timing speed and the QPF forecast. Between 12z Thu and 12z fri,
generally kept pops to chance levels under 50%, but did go for
likely pops around 60% for the western border and st. John
valley between 18z Thu and 00z fri, with chance pops elsewhere.

Also put in chance of thunder for those areas Thu afternoon and
evening.

There is a chance that the front could stall out near the coast
thu night into fri, and keep showers and a few storms possible
there, as per the 12z GFS and 00z ecmwf. Or as the 12z cmc and
12z ECMWF point toward, the front may be slower moving and
perhaps a stronger upper-level trough or even cut-off low could
cause increased pops to persist across a broader swath of the
cwa for Friday and even into the weekend. Given the uncertainty,
and the significant flip between the 00z and 12z ECMWF runs,
pops were kept low and the time frame later next week will need
to be monitored for possibly significant changes to the
forecast.

Aviation 00z Sunday through Thursday
Near term:VFR conditions are expected through the period with
no CIGS and excellent vis. Winds will be light tonight through
Sunday.

Short term:VFR conditions are expected across the region
Sunday night. Generally expectVFR conditions Monday, though
occasional MVFR conditions are possible across central and
downeast areas during the afternoon. Occasional MVFR ifr
conditions are possible Monday night into early Tuesday mostly
across central and downeast areas. Conditions will improve to
vfr levels later Tuesday.VFR conditions are expected Tuesday
night through Wednesday night. Occasional MVFR conditions are
possible Thursday, particularly across northern areas.

Marine
Near term: no significant weather is expected under high
pressure. Seas will remain around 2 feet or less.

Short term: winds seas will remain below small craft advisory
levels Sunday night through Tuesday. Visibilities could be
reduced in rain later Monday into Monday night, with a chance of
showers Tuesday.
