.SHORT TERM...
Today and Tonight.

Watching the cold front finally clear the area this morning. A few
showers have developed along the front and will push through the
southeast through the early morning before exiting by sunrise.
High pressure will begin to build into the area by the afternoon
behind a weak shortwave that will slide across the north. Really
the only impact to the area will be a little bit more sky cover
across the north through the afternoon. Behind the shortwave we
will clearing skies across the north with temperatures back to
freezing and below

.LONG TERM...
Wednesday through Monday.

We`ll be in the middle of a stretch of fair weather on Wednesday,
and a shortwave passing through will have little to no sensible
weather impacts. Afternoon highs should be in the 50s for most
locations. A cold night is expected to follow as surface high
pressure becomes centered nearby. Lows on Thursday should range
from the mid 20s North to lower 30s South. Many locations may
reach or exceed the 60F mark on Thursday and again on Friday as a
deep-layer ridge builds across the region.

Southerly flow is expected to increase Friday night through the
weekend as the trough to our west approaches. The advection of
moisture and warmer air northward in advance of a cold front could
yield widespread showers for Saturday and Sunday. This surface
front should get booted eastward on Sunday by the upper-level
shortwave, leading to cool and dry conditions on Monday.

.AVIATION...
12Z TAF Discussion.

Mainly a wind forecast for the next 18 hours as winds will
increase from the north as the dry airmass filters into the
region. Could see some sct to bkn decks around 4 to 5 kft at the
far northeastern sites (ANB/ASN) but only included sct at this
time. This will be influenced by a shortwave that should slide
through late this afternoon into tonight. No precipitation is
expected.
