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

A cold front dropping southward out of Canada early this morning
will stall over the forecast area today, then move back
northward later today and tonight. The front will be accompanied
by little fanfare today as moisture will be limited. Therefore,
we expected variable clouds with dry weather. Temperatures will
rebound to near 50 degrees across southeast zones to the 40s in
mountain valleys. Westerly winds will be quite gusty today,
especially in central and northern zones with G30 MPH possible.

The front will return northward tonight as a warm front as low
pressure approaches from the northern Great Lakes. Forcing for
ascent will increase across central and northern zones as
moisture increases. This will aid in the development of light
precipitation, especially across the north. Initially it should
be in the form of light snow which may allow for some slippery
spots for the early morning commute. Thereafter, temperatures
will quickly warm on Thursday, with highs around 60 expected
across the south with 40s and 50s elsewhere. The next system
quickly approaches Thursday afternoon resulting in increasing
PoPs by for rain showers by evening. Not out of the question
there could be a rumble of thunder.


KEY MESSAGE 2 DESCRIPTION...

A wave of low pressure rides along a cold front Thursday night,
bringing another round of mostly rain Thursday night. Enough
cold air may work in on the back side of the front for precip to
end as a few snowflakes across the north Friday morning, but
most of the precip should fall as plain rain. A few rumbles of
thunder are also possible through the overnight hours as some
elevated instability moves through ahead of the front.

KEY MESSAGE 3 DESCRIPTION...

Temperatures fall behind the front on Friday, with drier air
returning. Friday night looks to be one of the colder nights
we`ve seen recently, with lows dropping into the single digits
across the north, and teens to low 20s elsewhere. High pressure
then gradually builds eastward through the weekend, bringing
continued dry conditions and moderating temperatures. Highs
likely reach into the 50s on Monday, before another front passes
Monday night into Tuesday with a chance of showers, followed by
temps cooling back down into the midweek.

.AVIATION /12Z WEDNESDAY THROUGH MONDAY/...
Through 12Z Thursday: Conditions are expected to largely be
VFR today. The exception may be KHIE this morning where
lingering lower clouds or even a brief snow shower may bring
MVFR restrictions. IFR to MVFR restrictions will be possible in
light precipitation tonight as a warm front lifts north.

Outlook (Thursday through Monday):

Thursday: VFR conditions and southwesterly winds are expected,
although some lowering of cigs will be possible by late
afternoon.

Thursday night: IFR likely in rain, and possibly some snow at
HIE late.

Friday - Friday night: Improving to VFR with possible restrictions
lingering in the mountains.

Saturday through Sunday night: VFR expected.

Monday: MVFR and showers possible late in the day.

&&

.MARINE...
Periods of SCA conditions are expected on the waters through
Thursday as frontal boundaries cross the waters. Southerly SCA
conditions Thursday night switch to northwesterly behind a
passing cold front. High pressure then builds in through the
weekend, with SCA conditions likely easing by early Saturday.
SCA conditions are possible again on Sunday in southwesterly
flow ahead of the next approaching cold front.
