139 pm edt Mon aug 21 2017

Synopsis
High pressure will build south of the area today. Low pressure
will approach from the west on Tuesday. The low will track to
our north Tuesday night into Wednesday as it brings a cold
front across the area.

Near term through tonight
140 pm update...

scattered CU has dvlpd acrs the CWA this aftn tho it seems to be
pretty few and far btwn. Frontal bndry sitting up acrs wrn
quebec wl drop south tonight and bring clds and possible isold
showers this evng to the north. All eyes are turned to the west
coast as solar eclipse is extremely evident on satellite at this
time and progresses across the CONUS this aftn. Wl be evaluating
potential for svr wx shortly.

Previous discussion
a southwest flow around high pressure to our south will transport
unseasonably warm air across northern and down east maine
today. Expect mainly sunny skies across the region. H925
temperatures are forecast to reach around +22c yielding high
temperatures in the low to mid 80s across much of the area away
from the immediate coast.

A warm and humid night can be expected across the region tonight
as high pressure remains to our south. A cold front will
approach far northern maine from quebec this evening. The front
will stall just north of the region overnight. Expect partly
cloudy skies across northern areas along with an isolated
thunderstorm this evening and mainly clear skies down east.

Overnight lows will be in the 60s.

Short term Tuesday through Wednesday night
Tue will be ptly to msly sunny, very warm, and humid. Aftwrds
cumuliform cldnss will increase in the aftn across the N with
late day shwrs and tstms spcly across the NW as a cold front
from qb supported by a sig S WV alf apchs. Best support of shwrs
and tstms will be Tue ngt for most of the rgn as the front
begins to cross and the S WV alf pivots ene just N of the rgn.

Will mention hvy rn and gusty winds as linear TSTM segments
appear likely Tue ngt with good frontal forcing and elevated
cape, with very hi fzg lvls making hail unlikely. Many, but not
all lctns could experience an inch or more of rnfl before shwrs
exit the fa Wed morn. In the wake of the cold front Wed aftn
and ngt, cooler and drier air from cntrl can will ovrsprd the
rgn.

Long term Thursday through Sunday
Cannot rule out isold day tm shwrs with weak S wvs periodically
crossing spcly NRN ptns of the rgn, otherwise, ptly cldy skies
by day and msly clr skies by ngt is xpctd this late week into
next weekend with both cooler hi and low temps compared to the
near and erly short term pds.

Aviation 18z Monday through Saturday
Near term:VFR next 24 hours with potential MVFR vsbys btwn 07z
and 12z for northern terminals.

Short to long term:VFR conditions xpctd all TAF sites
tue... Then clgs vsbys lowering to MVFR and then ifr Tue ngt into
wed morn in shwrs, tstms, and fog. All TAF sites should then
improve back toVFR behind a cold front Wed aftn and cont so
thru the late week.

Marine
Near term: winds seas will remain advisory levels through
tonight.

Short to long term: no hdlns initially, but SW winds and wvs
could apch and possibly exceed SCA thresholds Tue ngt into wed
morn just ahead of a cold front. In addition, marine fog could
become an issue Tue ngt into Wed morn as moist tropical air
streams nwrd across cold gulf of me waters. Aftwrds, winds, seas
and fog should diminish Wed aftn and ngt as winds become
offshore.

Went sig blo ww3 WV guidance for fcst WV hts Tue ngt into wed
morn given hi sfc wind bias input into this guidance in this
flow regime this tm of season. Otherwise, we kept within 80 to
90 percent of the guidance for the rest of the fcst. Primary wv
pds will msly in the 5 to 7 sec range.

Car watches warnings advisories
Me... None.

Marine... None.

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
