Synopsis
High pressure and sunny weather will arrive for the latter half
of the weekend along with the start of a gradual warming trend.

By mid week, unsettled weather returns with the approach of our
next storm system.

Near term through Sunday
930pm update.. Sskies are clear across most of the area which
should allow temperatures to continue to drop nicely.

7pm update... Only minor adjustments as winds begin to diminish
and skies clear into the evening as high pressure approaches.

A nice spring day is in progress with much of southern and
central nh along with portions of SW maine under mostly sunny
skies. To the north and east, cyclonic flow had more of an
influence with thickening cumulus clouds as well as
stratocumulus towards the carrabassett valley and the mid coast
of maine. Gusty NW winds have made the day a little more chilly,
with gusts in the 20 to 25 mph range. The surface pressure
gradient will be relaxing, and this will allow winds to decrease
overnight.

Overnight lows will drop in low moisture content air, bottoming
out to near current afternoon dew points (20s). Expecting some
patchy frost across the region once winds die down. Since the
growing season has not technically started, will not be
outlooking it at this time.

Short term Sunday night
Sunny skies and lighter winds will dominate the weather pattern
Sunday. Heights will increase with ridging both at the surface
and aloft moving in from the west. Temperatures will respond and
be slightly warmer than today... With mid 40s north to mid to
upper 50s south.

Long term Monday through Saturday
High pressure will be in control of the sensible weather through
Tuesday. Warm weather will also be the rule Monday and Tuesday
with highs in the 50s and 60s. By Wednesday our weather changes
for the worse as models agree on moving a surface low from the
gulf states northeast along the east coast to a position in the
gulf of maine by Thursday morning. This low will have a tropical
connection but models are indicating that the heaviest
precipitation will move east of the forecast area and out to
sea. This will likely be a colder rain with some snow possible
in the highest elevations of northern new hampshire and
northwest maine. With the warm weather melting the mountain
snow Monday and Tuesday and the expected rainfall Wednesday and
Thursday we will see a gradual rise on rivers through the week.

Ensemble river guidance shows just a few river location possibly
making it to flood stage. This in the end will depend on exactly
how much rain we get. The models are indicating that another
surface low will move into new england late Saturday.

Aviation 03z Sunday through Thursday
Short term...VFR conditions prevailing throughout the period. Nw
winds will diminish this evening and increase once again on
Sunday... Although they won't be as strong.

Long term...VFR expected Monday and Tuesday. MVFR condition will
will move in late Tuesday night in southern locations and spread
north. Ifr is expected in rain and fog at all location by
Wednesday afternoon. Ifr will likely continue into Thursday.

Marine
Short term... Quiet on the waters with low seas and winds
weakening due to a slackening pressure gradient.

Long term... Quiet on the waters Monday. Winds will increase from
the southwest Tuesday and high pressure slides off the coast.

Winds may approach SCA criteria Tuesday afternoon. An
increasing east to southeast flow will likely see winds and seas
reach SCA criteria Wednesday.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

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.
