.WHAT HAS CHANGED...
Forecast remains on track. A cold front is currently moving
through New England and will continue to bring drizzly and rainy
conditions to New Hampshire and Maine.

&&

.KEY MESSAGES...
1. Rainy conditions will continue through the afternoon.

2. Light snow on Tuesday gives way to a dry, warming end of the work
week. Our next chance for some widespread showers arrives Friday or
Saturday.

&&

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

A cold front will slowly move across New England through the
remainder of today. The front will consist of mainly steady rain,
with very little instability to work with. This is due to a strong
low-level inversion, which is also what has been keeping the region
in the upper-30s and lower-40s today.  The rain should exit the area
by the late-afternoon. A northwest breeze looks to pick up behind
the front and allow for cold air advection tonight. Temperatures
should be noticeably chillier by tomorrow morning.

KEY MESSAGE 2 DESCRIPTION...

After a mainly dry Monday outside of some mountain snow showers,
the next weak wave approaches on Tuesday as the main trough
axis moves overhead. This will lead to our next low to medium
(30 to 50 percent) precipitation chances. While some rain may
briefly mix in across far southern New Hampshire, light snow is
expected to be the main precipitation type. Any accumulations
will be light, but a dusting to a half inch or so will be
possible over portions of central/southern New Hampshire and
Interior/coastal Maine, mainly on grassy surfaces. The highest
terrain could potentially see an inch or two. Most of the light
snow should move out by the evening hours.

High pressure and upper ridging then dominates the weather pattern
Wednesday before the next longwave trough starts to approach the
region and we transition back into southwest flow aloft to end the
work week. While specifics are still unclear this far out, it looks
like we will see the next chances for precipitation in the Friday
through Sunday timeframe.

Regarding temperatures, cool highs remain in place on Tuesday with
highs ranging from the upper 20s and lower 30s north, to the low to
mid 40s south. The warmup then begins in earnest on Wednesday and by
Friday highs are forecast to range from the lower 50s north, to the
low to mid 60s south (mid to upper 50s across the Midcoast). While
NBM spread increases through the weekend and into next week, it does
appear that above to well above normal temperatures should generally
stick around.

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
Low restrictions are expected this afternoon as rain moves
through the area. Conditions start to improve tonight and will
allow for most places to rebound to VFR by Monday morning. A
possible exception to this is KHIE, as some snow showers there
may prolong restrictions. VFR will continue through the day on
Monday, but conditions may degrade again Monday night due to
incoming wintry precipitation.

Outlook...

Tuesday: Generally VFR with MVFR or lower conditions expected
in light snow showers during the day.

Tuesday night-Thursday: VFR conditions are expected through
much of next week as we see a period of quiet weather.

Friday-Friday night: Increasing precipitation chances with
restrictions possible.

&&

.MARINE...
Westerly SCA winds will continue through Monday. Winds will
weaken to sub-SCA Monday afternoon and stay sub-SCA through
Tuesday morning. Seas of 5-8ft are expected this afternoon and
will gradually lower to 2-4ft by Tuesday morning.

Sub-SCA conditions should continue through the day on Tuesday,
but a period of wind gusts 25-30kts with bring that to an end
Tuesday night as a front crosses the waters. Wednesday may also
feature sub-SCA conditions as high pressure begins to build over
the waters, but the pressure gradient tightening ramps wind
gusts and waves up above SCA criteria Wednesday night through
Thursday night. Waves might be a little slower to settle than
winds, but conditions should improve on Friday with high
pressure still in place. Another front crosses the waters
Saturday with brief SCA conditions possible.
