&&

.KEY MESSAGES...
1. A couple of relatively low-impact systems to affect the
region today into Friday with some mountain snows and rain in
most other areas.

2. Below normal temperatures over the weekend with mostly dry
weather.

3. Pattern turns more active early to middle of next week.

.DISCUSSION...
KEY MESSAGE 1 DESCRIPTION...

A warm front lifting through the region early this morning will
aid in the the development of light snow in the mountains and a
period of light rain or rain showers south of the foothills.
There could be some slippery spots in the mountains and portions
of the foothills early this morning, but overall snowfall
amounts should be less than 2 inches. South of there, rainfall
amounts will be very light. In fact some areas in the far
southern zones may remain dry.

The warm front that will lift northward early this morning will
move back southward as a cold front during the afternoon.
Southwesterly flow south of the front will allow temperatures to
warm into the 60s across southern zones and 50s elsewhere except
the far north. Moisture streaming eastward along and in the wake
of the sagging front will aid in a renewed batch of rainfall to
begin across the region this afternoon. Some model guidance
indicates that there may actually be a short period of heavy
rainfall across southern zones with a few rumbles of thunder
possible this evening.

As far as precipitation type goes this afternoon and evening, we
are looking at all rain. However, as the precipitation shield
moves out later this evening, it`s possible that a very brief
period of snow occurs on the northern fringe.

High pressure moves into the region for Friday with dry weather
and colder temperatures.


KEY MESSAGE 2 DESCRIPTION...

Broad high pressure builds in over the weekend. The core of the
cold airmass will pass overhead Saturday morning through the
afternoon. Lows Saturday morning will bottom out in the single
digits across the north and in the teens south of the mountains.
Highs saturday afternoon will range from the 20s north to mid
30s south. Another night with lows in the single digits north to
teens south is likely Saturday night with temperatures starting
to rebound Sunday as flow turns more southwesterly.

KEY MESSAGE 3 DESCRIPTION...

Zonal flow across the CONUS early next week will become more
amplified as a series of Pacific troughs march across the West
towards the middle of next week. A short wave within zonal flow
pattern will bring a clipper system across southeast Canada Monday
that will bring chances for rain and snow showers in the mountains.
Thereafter, a signal exists for above normal precipitation through
the end of next week as multiple waves eject out of mean troughing
centered over the Rockies.

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
Through 12Z Friday...Ceilings ranging from IFR to MVFR from PWM,
PSM, AUG and RKD will gradually improve to VFR later this morning or
early afternoon. Intermittent light rain may also occur but little
to no visibility restrictions are expected. VFR elsewhere for much
of today. Ceilings lower again late this afternoon and evening as
the next round of rain moves in with widespread MVFR to IFR
restrictions. Rain could be briefly heavy, especially over southern
NH and SW Maine. Conditions should start to improve after 07Z-09Z
tonight as northwest winds start to increase (possibly gusting 20-25
kt prior to 12Z Friday morning).

Outlook...

Friday through Saturday night: Mainly VFR, no sig wx.

Sunday: Mainly VFR with SW winds gusting 15-20 kts. Some MVFR cigs
possible at KHIE.

Sunday night and Monday: Clouds thicken and lower towards Monday
morning. Scattered rain and snow showers possible at KHIE with rain
showers south of the mountains, mainly north of a line from KLEB to
KRKD.

&&

.MARINE...
Active weather pattern will bring periods of SCA conditions straight
through the weekend. First period of SCA conditions will be
today and tonight as south to southwest flow increases ahead of
a cold front. Winds will turn northwest tonight as the cold
front pushes south. This will keep waves above criteria straight
into Friday.

A period of SCAs may be needed Friday night in offshore flow. Winds
and seas stay below SCA thresholds Saturday into Sunday morning. SW
flow strengthens Sunday with SCAs likely needed by Sunday afternoon,
lasting into Monday.
