.DISCUSSION...
KEY MESSAGE 1)

Widespread stratus across the area this afternoon will erode away
from the southwest heading into this evening as surface high
pressure builds into the mid Ohio Valley. This will also lead to a
decrease in winds with some decoupling likely later tonight across
at least the southeast two thirds of our area -- and this is where
the highest confidence in frost development exists. Frost
development will be a bit trickier across our northwest as a cold
front will approach from the northwest later tonight. This will lead
to some increase in clouds and winds late which may limit frost
development. However, given some of the uncertainty, have opted to
err on the side of caution and issue a Frost Advisory for our entire
area tonight.

A reinforcing shot of cold air will move in behind the front Monday
into Monday night. This will lead to sub-freezing temperatures
Monday night across about the northern half of our area -- where we
have issued a Freeze Watch. We may eventually need a frost advisory
for Monday night across our south but this will be dependent on how
much winds are able to stay up through the night.


KEY MESSAGE 2)

Developing mid/upper level southwest flow will lead to a warming
trend through mid week with above normal temperatures expected to
persist into the weekend.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
MVFR to VFR stratus across the area this afternoon will erode away
from the southwest heading into this evening as surface high
pressure builds into the mid Ohio Valley. A cold front will then drop
southeast through the region late tonight into Monday. This will
lead to an increase in MVFR to lower VFR cigs from the north late
tonight and into Monday morning.

OUTLOOK...No significant weather expected.
