Synopsis
A cold front will move into the area overnight and then stall
through Monday. An occluded front from the west will cross the
region later Monday night with unsettled conditions continuing
behind this front through midweek.

Near term through Monday
120 am update...

sfc analysis had front boundary extending from NE aroostook
county back into N somerset county. Hrly temps were adjusted to
fit the latest conditions W readings in the 50s across northern
1 2 of the CWA while central and downeast areas were in the 40s.

Adjusted the overnight mins a bit especially downeast as temps
were already in the low mid 40s. Some low clouds were moving
into downeast area and the bangor region W a S wind per the
latest obs and satl imagery. This will help to halt a further
drop in temps overnight.

The radar showed some light showers along and north of the
boundary. Decided to pull back the pops further to cover the
far N and w.

Original discussion...

expect showers and isolated thunder over northern areas tonight
as a cold front stalls. Skies will remain partly to mostly
cloudy tonight into Monday across southern areas. The front will
move northward into canada Monday morning. An occluded front
will approach from the southwest later in the day Monday with
more showers breaking out ahead of this front.

Short term Monday night through Wednesday night
The first round of shwrs will traverse across the fa ahead of a
weak occluded front Mon ngt, with fcst rnfl amts durg this pd a
quarter inch or less and MAX pops about 80 percent attm. After
a relative break in shwrs erly Tue morn, another round of shwrs
with isolated tstms looks like a good bet for Tue aftn into erly
eve with MAX pops in the high likely range as spokes of upper
lvl energy rotate arnd a broad upper low ovr ont prov. These
shwrs will move E dissipate by ovrngt tue, leaving late ngt
patchy fog.

Otherwise, the same process will begin on Wed with another S wv
movg wsw to ene from the great lks as the upper low remains ovr
ont prov. Shwrs will increase again in the aftn with the
addition of day tm htg to destabilize the lower to mid
atmosphere. This time, there appears to be a little more of
mucape upwards to arnd 500j kg for a better chc of tstms in the
aftn into erly eve with MAX pops in the likely range. Shwrs and
any tstms will weaken and lessen in cvrg again ovrngt wed.

Temps in the short term will be below avg for hi temps on tue
but then recovering closer to normal hi temps on Wed with a
little more in the way of morn sunshine xpctd this day.

Long term Thursday through Sunday
The overall lw pattern will feature weakly positive pna and nao
teleconnection forcing ovr na, which will keep upper lvl
troffing ovr the ERN u.S. Alg with contd unsettled conditions
for the late weekend for our rgn with perhaps a break in shwrs
for the rgn by sun. Until then, there will be a chc of shwrs
every aftn and erly eve from Thu thru sat, with isold thunder
possible Thu aftn erly eve. Despite day tm cld cvr and shwrs
spcly aftn, most of the really cool llvl air will remain in
cntrl can, so temps will be close to seasonal norms.

Aviation 05z Monday through Friday
Near term: expect MVFR ifr conditions tonight and Monday, with
some isolated showers also to be dodged north of khul through
tonight, and.

Short to long term: mslyVFR all TAF sites, with intervals of
MVFR clgs and vsbys in heavier shwrs and patchy late ngt ifr
clgs Mon ngt, Tue ngt and perhaps Wed ngt.

Marine
Near term: have used the NAM for sustained winds. For waves:
currently a southerly swell is the primary wave system (2-3
feet 8-9 seconds). With light winds expected this wave group
will continue to be the primary wave group through tonight.

During the day Monday expect easterly winds to increase in speed
producing a secondary wave system. Will use the nearshore
prediction system for wave grids.

Short to long term: no hdlns anticipated attm, with winds and wv
hts msly below SCA criteria. Went with about 85% of ww3 wv
guidance for fcst WV hts this update, with WV pds msly between
5 to 7 secs.

Car watches warnings advisories
Me... None.

Marine... None.

Near term... Hewitt

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. 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.
