.SYNOPSIS...
Dry, but cool weather can be expected through the weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
No major changes were needed for the mid mrng update as cold
advection continue to flow across the region in the wake of last
nights frontal passage. Temperature is expected to be around 5
degrees below average under an amplifying eastern CONUS trough.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
Amplified upper troughing is progged to persist across Eastern North
America through the weekend. Sfc high pressure building under the
resulting NW flow aloft should maintain dry weather through the
period, though a couple of weak troughs rotating around the low could
result in some periodic increase in clouds across the Lower Great
Lakes/Upper Ohio Valley region.

Temperature is expected to remain about 5 to 10 degrees under the
calculated normals for the weekend.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
The upper low is expected to move east Sunday. Riding should then
build across the Central and Eastern CONUS through mid week, ahead of
a Western CONUS trough. This should result in continued dry weather,
but with a warming trend.

&&

.AVIATION /14Z THURSDAY THROUGH MONDAY/...
Sfc high pressure with nwly flow aloft will maintain a widespread
MVFR stratocu deck through the majority of the TAF period. Shortwaves
embedded within the flow may promote the development of a few snow
showers, mainly near FKL and DUJ, with brief reductions in visibility
possible. Otherwise, gusty wind to near 20kts is expected through
tonight.

.Outlook...
Ceiling restrictions are possible with a late Friday cdfnt.

&&

.PBZ WATCHES/WARNINGS/ADVISORIES...
PA...None.
OH...None.
WV...None.
