.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
A light northerly wind shift will occur overnight as a cold front
moves through the area. Otherwise, VFR conditions will continue
with an occasional broken mid-level cloud deck at northern most
sites through mid morning. Surface high pressure builds in behind
the front Saturday to maintain confidence of good flying weather.

..UPDATE...

DISCUSSION...
A shortwave trof was moving east- southeast across the Upper
Midwest this evening with an associated trailing weak cold front
currently positioned from the Texas Panhandle to just within
Northeast Oklahoma to Central Missouri and up into the Great Lakes
Region. Behind the boundary...northerly winds along with a few
weak radar echos were observed across Kansas. With the dry air
in place...no precip was reported to be reaching the surface.
Ahead of the boundary...southerly winds and temps in the 50s/60s
were common across Eastern Oklahoma and Northwest Arkansas.

Overnight tonight...the weak cold front will continue to push
through Eastern Oklahoma and Northwest Arkansas and exit the
region early Saturday morning. Associated with the
front...scattered to broken high clouds will also continue to move
across much of the CWA through the night and help to keep temps
from dropping to far before skies begin to clear out from
northwest to southeast early Saturday morning. Thus...temps in the
50s look to remain common for much of the overnight period with
lows in the mid/upper 40s early Saturday morning across the CWA.
With continued cloud cover and temps slow to cool...the main
noticeable part to the frontal passage will be the northerly
winds of 5-15 mph.

For the evening update...have adjusted overnight hourly
temp/sky/dewpoint/wind grids to account for the mentioned above
and also for the latest trends/observations.
