Synopsis
High pressure will crest over the region on Tuesday before
shifting offshore to the southeast. Low pressure will slowly
move northeast through southern quebec on Wednesday. A secondary
trough of low pressure will drop southeast through the region
Thursday night and Friday. High pressure will gradually build in
from the west over the weekend.

Near term tonight
8pm update...

have updated the forecast to adjust for latest observations just
as the last of the remaining showers exit stage right. Also
added some fog for the interior valleys as well as the augusta
region where some heavier rain late this evening could lead to a
greater chance for fog formation.

530pm update...

have updated the forecast to refine hourly precipitation chances
and drop the severe thunderstorm watch. Best remaining
thunderstorm activity is north of the watch and decreasing in
intensity, with the axis of convection offshore of southern
areas and nearing the coast in eastern areas. Fog is possible
tonight especially in areas that got rain this evening.

Original discussion...

a short wave trough will move across the region this evening,
and will be associated with scattered showers and thunderstorms.

Given the amount of moisture and CAPE along with steep low
level lapse rates, a few storms may be severe. Damaging winds
and torrential downpours will be the main threat. The threat for
storms ends by 00z as a short wave trough quickly moves
offshore. Clearing is expected tonight in the wake of the front.

Valley fog, some dense, is expected overnight. Some dense fog
will also be possible on the midcoast as well.

Short term 6 am Tuesday morning through Tuesday night
Fair weather expected Tuesday with short wave ridging in place.

Highs will be well into the 80s, but with far less humidity.

The next short wave trough and attendant warm front approaches
late Tuesday night, with an increasing chances for showers and
a few thunderstorms across southern zones late.

Long term Wednesday through Monday
Unsettled weather through Friday and drier air will move in for the
weekend.

A frontal system to the south of the forecast area will move back
north with increasing chance of showers and thunderstorms through
Wednesday night. Dewpoint temperatures will climb back to near
70 on Wednesday afternoon. Wednesday will start out with chance
showers and thunderstorms with the warm front passage. The cold
front will pass through later in the day giving likely showers
and thunderstorms in the afternoon and evening.

Thursday will still be a warm day but dewpoint temperatures will be
a bit more comfortable. The cooler and drier air sets in for Friday
with dewpoints in the mid 50s or less. Showers possible in the
mountains Friday afternoon.

High pressure from the west will dominate the weekend with
cooler and drier air. High temperatures over the weekend and
Monday are forecast to be in the 70s with low humidity.

Aviation 22z Monday through Saturday
Short term...VFR to start the night, but fog is possible in the
western new hampshire valleys including leb and hie. Rain this
evening at aug and psm will increase the chance of fog there
tonight as well. Should see everyone return toVFR Tuesday
morning.

Long term... Expect occasional MVFR ifr in showers and
thunderstorms on Wednesday and Thursday. Friday possible MVFR
in afternoon showers at hie butVFR expected elsewhere.

Marine
Short term... Conditions are expected to remain below sca
thresholds through Tuesday night. Marine fog is likely off the
midcoast of me tonight.

Long term... SCA possible Wednesday and Thursday mainly due to
seas.

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.
