1243 pm edt Thu apr 27 2017

Synopsis
A weakening area of low pressure centered over CAPE cod will
continue to drift northeast into the gulf of maine today into
tonight. This will prolong the cool damp conditions over all but
far western and northern new hampshire today into tonight.

A front accompanied by showers will move across the region
Friday morning and will help to sweep out the cool and wet
conditions with warmer temperatures Friday afternoon and into
the weekend. That may be short lived however... As cooler air
tries to slip back in from the north Sunday into Monday while
low pressure approaches from the south.

Near term /through tonight/
1240pm update...

forecast in good shape with no changes needed.

920am update...

no changes needed other than copying in current temperatures.

Cloudy, muggy day underway with only a bit of drizzle.

Previous discussion:
the weakening of low pressure centered over CAPE cod will
continue to slowly drift to the northeast today into the gulf of
maine. This will prolong a cloudy damp and cool air mass over
southern and eastern areas today into tonight. Some partial sun
may occur over far western and northern nh. The low levels will
remain saturated elsewhere since no mechanism is available to
ventilate the low levels. Patchy drizzle and fog may occur
especially along the coast. High temps will be warmest across nh
and the western maine mountains reaching into the 60s while
over maine portions temps will remain in the 50s with coolest
temps along the coast.

Short term /Friday through Friday night/
Tonight most areas remain cloudy and damp. Some patchy drizzle
and fog may reform over eastern and southern areas of maine due
to a very light moist onshore flow. A front approaches from the
west late tonight and moves across the region from west-east
Friday morning. Scattered showers and isolated thunderstorms
will accompany this fast moving front. Also this will be the
much needed mechanism to force mixing and clearing of the
trapped low level moisture during the afternoon allowing a
return to partly to mostly sunny skies and warmer temps across
all areas as winds shift to southwest. Temps will be in the 70s
over all southern and central areas Friday but 60s in the
mountains and even cooler along the midcoast areas where temps
will be in the mid 50s to mid 60s.

Long term /Saturday through Wednesday/
Not too much change to the extended forecast this morning as
much of the 00z guidance suite is in agreement with the big
picture over the next week.

A strong short wave trough is expected to move eastward fairly
quickly across southern canada Friday night and Saturday. This
will act to drive a cold front southward across our CWA on
Saturday. While Saturday looks to get quite warm and potentially
somewhat unstable, the front looks to be pretty moisture
starved and the timing of the short wave trough energy looks a
bit too fast for much in the way of showers and thunderstorms.

Can't rule out a couple, but the day may very well end up being
dry.

Strong high pressure dives in from the NW Saturday night and
Sunday and will bring with it cool and dry weather. Sunday
should be a winner of a day with strong higher pressure settling
overhead. Light winds should be the theme in the afternoon along
with highs around 60. Some high clouds may move in late.

The high quickly moves off to the east Sunday night allowing for
a WAA pattern to develop. This may mean another couple-day
period of rainy, drizzly, and cool weather for our region Monday
and Tuesday.

Aviation /18z Thursday through Tuesday/
Short term... Widespread ifr conditions will continue today
into tonight across eastern interior and coastal areas. Over
far western and northern areas conditions will improve during
the day to MVFR. MVFR conditions in scattered showers and
isolated thunderstorms expected Friday morning over western
areas while eastern areas start out ifr and then slowly improve
toVFR during the afternoon behind the fropa.

Long term... A series of warm fronts will try and lift into nrn
new england thru the weekend. This will most likely lead to
periods of widespread cloud cover. Significant periods of MVFR
cigs are likely... And areas of ifr could form in the overnights
in onshore flow. Any ifr conditions would be most likely near
the coast... With leb and hie being least likely to see
significant impacts.

Marine
Short term... The persistent light onshore flow will continue
through Friday. So will continue the SCA for hazardous seas
through Friday for the outer waters. Seas will remain 5-7 ft
over the outer waters through Friday and only 2-4 ft in the
bays.

Long term... Marginal SCA seas on the ocean waters will subside
Friday night. A cold front crosses the waters on Saturday. The
caa regime behind this front could allow for a period of sca
winds Saturday and Saturday night.

Fire weather
Cool damp conditions with light winds will continue today into
tonight as weakening low pressure moves through the gulf of
maine. A front will move through Friday with scattered morning
showers and even an isolated thunderstorm possible with its
passage. Clearing and warmer weather returns Friday afternoon
into Saturday although a few widely scattered mountain showers
will be possible.

Gyx watches/warnings/advisories

Friday for mez023-024.
