Synopsis
A storm near bar harbor maine will continue to deepen and move
north. The tight pressure gradient around the storm will keep
windy and colder conditions in place through Saturday. High
pressure will build across for Sunday bringing milder
conditions. A new frontal system is expected early next week
followed by dry weather for Tuesday through midweek.

Near term until 6 am Saturday morning
Radar is becoming quieter with each passing hour with little
more than light snows showers and isolated flurries left.

Earlier we had some rumbles of thunder and several reports of
small hail graupel. The steepest mid level lapse rates are
moving east of the area as of late evening and conditions will
continue to improve as heights aloft rise in the wake of the
departing upper low.

We are going to stay windy in the 25-40 mph range, but gusts
reaching advisory criteria do not look likely.

Lows in the teens and 20s will be about 5-10 deg colder than
normal. A gusty wind will make it feel colder.

Short term 6 am Saturday morning through 6 pm Saturday
Snow showers should end early Saturday morning followed by
gradually subsiding winds into Saturday night. High pressure
will provide dry wx over the weekend with temperatures trending
warmer on Sunday.

Long term Saturday night through Friday
Model guidance is in decent agreement with the next system
returning light precipitation to the area late Sunday night into
Monday. I made a few adjustments to the temperatures. Looking at
some snow mixing with the rain at times late Sunday night into
Monday, especially across the north.

Dry weather is fcst from Monday night through late week. Temperatures
should trend colder behind the system Monday, given the source
of the airmass. Minus 30 degree air at 850 mb over eastern
canada Sunday night is cold for late march.

Temperatures will rebound above average later in the week. I made
a few adjustments, but no big changes.

New ec (12z) similar to the 00z run of the ec and other models,
as we head into late Friday into next weekend, that a system
will lift northeast across the great lakes. This low will bring
mild air into the area, but also a tendency of the cold front
to slow down with a ridge of high pressure over the southeast.

This will result in some showers by Saturday.

Overall, an active weather pattern for the lower 48.

Aviation 03z Saturday through Wednesday
A windy northwest flow continues across the entire region this
evening, with gusts frequently reaching 30 knots. Snow shower
activity beginning to wane across the region, especially noted
across the downslope regions of central and eastern portions of
the area.

Kjst and kbfd, our typical airfields susceptible to a cold
unstable upslope flow continue to drift in and out of MVFR to
occasional ifr conditions. Even here, with loss of instability
overnight, expect snow showers to continue to decrease in
intensity overnight. Winds will remain brisk from the northwest
at 15 to 15 knots, with some gusts around 30.

Vfr conditions across the region, but with the strong northwest
flow continuing. Indications are that the flow will begin to
relax late in the TAF period. Have included a 22z group
indicating the trend downward of the winds.

Outlook
Sat...VFR, but brisk.

Sun... No sig wx expected.

Mon... Rain snow low CIGS possible, mainly N and W mtns.

Tue and wed... No sig wx expected.

Fire weather
Strong northwesterly winds in the wake of cold front will
persist through Saturday. Relative humidities are forecast to
drop to 30% or less Saturday and Sunday afternoon. However,
in collaboration with fire weather partners, recent significant
rainfall and snow rain showers today will keep fine fuel
moisture above 10% through the weekend. Thus no flags are
expected at this time.

Ctp watches warnings advisories
None.

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.
