High pressure will build across the region overnight. Any
remaining isolated showers will dissipate around midnight.
Otherwise, mostly clear skies are expected across the region
overnight along with patchy fog. Overnight low temperatures will
generally range from the mid 50s to around 60 north, to the lower

cloud cover. Have also included patchy fog on the coastal waters
overnight.

Previous Discussion...
A cold front approaching from the northwest could spark scattered
storms in the north on Wednesday afternoon. Nothing too strong
expected. Expect Downeast to remain dry. Warm and fairly muggy,
but dewpoints should be just a touch lower than Tuesday`s.
&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
Low pressure will pass to the north of the state Wednesday Night.
Expect showers and thunderstorms in the evening as the front
approaches. More showers and thunderstorms are expected to break
out across the state during the day Thursday as the front moves
across the region. For Friday the front is expected to stall near
the coast, so expect more showers in the south with dry conditions
expected in the north Friday.
&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
Uncertainty resides for the weekend into early next week.

Frontal boundary stalled along the coast will be the focus for
some showers and perhaps a few tstms Friday night. Further n and
w, drying out. Overnight lows are forecast to be in the low to mid
50s n and w while central and downeast areas will see upper 50s to
lower 60s.

Confidence is low in regards to the weekend w/discrepancy in the
longer range guidance. The ECMWF along with its individual
ensemble members along w/the GFS shows some light showers for
Saturday but drying out later Saturday into Sunday.The ECMWF being
most pessimistic especially for the coast w/its forecast showing
and overrunning stratiform rain. Decided stay w/a blend and keeps
low chance pops along the coast Saturday and went much drier for
Sunday. Brought chance pops in for Monday as an upper disturbance
moves across the region. Temperatures are forecast be near normal.

.AVIATION /03Z WEDNESDAY THROUGH SUNDAY/...
NEAR TERM: Variable conditions will occur with any patchy fog
overnight. Otherwise, generally VFR conditions are expected across
the region overnight through Wednesday. However, variable

.MARINE...
NEAR TERM: Winds/seas are expected to remain below small craft
advisory levels overnight through Wednesday. Have included patchy
fog overnight into early Tuesday with this update.

SHORT TERM: Have used the NAM12 to initialize wind grids through
Friday then reduced model winds by 10 percent to compensate for
cold sea surface temperature. transition to super blend winds
late Friday. For waves: With wind speed expected to stay below 10
knots through Sunday expect incoming long period swell to dominate
wave systems. Have used the Near Shore Wave Model to populate wave
grids. Will reduce wave heights by 1 foot through Friday as
boundary wave heights appear too high.
