Synopsis
Winds will diminish as high pressure gradually builds in from
the west today. The high will crest across the area tonight
before retreating offshore. Low pressure will approach from the
great lakes late tonight and Thursday. An associated warm front
will move into the area on Thursday followed by a trailing cold
front Thursday night. The clouds and precipitation with this
system will slowly exit the area on Friday. After a brief break
late Friday into Saturday, another low will bring more unsettled
weather late Saturday into Sunday.

Near term through today
At 06z... A 992 millibar low was vicinity of CAPE breton with a
1023 millibar high draped across the great lakes. We continue to
see gusty northerly winds across the area between these two
features. GOES infrared imagery showed some lingering low and
mid cloudiness across all but southern new hampshire and extreme
southwest maine. For today... The low retreats further offshore
and the ridge slides eastward. Skies will become mostly sunny
throughout with pressure gradient and gusty northerly winds
subsiding. The slackening surface gradient should allow the flow
to turn onshore later today. Highs will range from the lower 60s
across the mountains with mid 60s to lower 70s for the remainder
of the forecast area.

Short term tonight through 6 pm Thursday
Outside of a few high clouds... A mainly clear start to the night
under the cresting surface high. The light winds... Dry
atmosphere... And mainly clear skies should allow temperatures to
drop off quickly before midnight. We may see some spotty frost
across mountain sections before high and patchy mid clouds
spill over the top of the ridge later tonight and put a lid on
further cooling. Lows will range from the mid 30s to around 40
in the mountains... With 40s elsewhere. On Thursday... The warm
front lifts north into the area with thickening clouds and an
increasing chance for showers and scattered thunderstorms as the
day progresses. Southerly flow warms the area into the 60s with
a few 70 degree readings in new hampshire. Meanwhile the islands
and mid coast maine will be limited to the 50s for high temperatures.

Strong convection will likely fire across the eastern great lakes
in the warm sector by afternoon while we're stuck in a cooler
and more stable airmass.

Long term Thursday night through Tuesday
The Thursday night period will start out unsettled as an
amplifying short wave trough moves southeastward into the
forecast area. An attendant strengthening sfc low pressure
center will move across the forecast area. A little tough at
this time to pin down where the sfc warm front will be during
the Thursday evening hours, but consensus is that it will be
draped in a w-e fashion in the vicinity of southern nh.

Widespread showers are expected Thursday evening as the short
wave trough approaches. Strengthening dynamics and some weak
elevated instability may allow for embedded thunderstorms during
the time frame as well and have kept the mention in the
forecast. There is a low probability that strong convection well
to our west Thursday afternoon could make it into southern nh
during the evening hours in a weakening state. However, most
guidance pinches off the steep mid level lapse rates and
best instability well to our south so severe weather is not
expected at this time.

Friday may end up being much like this past Tuesday with low
pressure departing southeastward through the gulf of maine. Lots
of clouds, cool temperatures, gusty NW winds, and occasional
light showers. Best chance of measurable precipitation will be
in the mountains.

High pressure moves in Friday night into early Saturday with
fair weather expected then. However, a fast-approaching warm
front will spread widespread showers across the region from west
to east Saturday afternoon and especially Saturday night. Just
enough elevated instability may be present Saturday evening to
allow for embedded thunderstorms, especially in the south.

Showers linger into Sunday morning before likely moving out
during the afternoon hours. The next similar system may arrive
early next week (mon or Mon night based on latest consensus).

Aviation 06z Wednesday through Sunday
Short term through Thursday ...VFR. Sfc wind gusts up to 25 kt
through 15z today at me terminal sites then diminishing. Areas
of MVFR developing aft 18z Thu in shra and isolated -tsra. Lcl
ifr psb vcnty of the coast in marine stratus and fog aft 21z
thu.

Long term... MVFR conditions in rain showers and low clouds are
expected Thursday night with areas of ifr expected north of warm
front which is expected to be across southern nh. Embedded
thunderstorms are possible as well. MVFR in showers Friday
morning before turningVFR during the afternoon and night. MVFR
to ifr conditions may return Saturday afternoon and night in
more rain.

Marine
Short term through Thursday ... Gusty northerly flow continues
and we should see gusts up to 25 kt through mid morning based on
latest hires models. I've extended the SCA for the outer waters
through mid morning. Thereafter... Quiet with winds seas below
sca as high pressure crosses the waters. A warm front moves
north into the waters by late Thursday... But winds should
remain below SCA as we have a tough time mixing given warmer air
over the cold marine waters.

Long term... Marginal SCA conditions are possible Thursday night
and Friday, followed by another chance of SCA conditions
Saturday night and Sunday.

Me... None.

Nh... None.
