.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Scattered to broken high level ceilings should remain common
across Eastern Oklahoma and Northwest Arkansas through the
afternoon hours. Overnight tonight...cloud cover associated with
the northward movement of Tropical Storm Cindy is forecast to
spread over the region with broken/overcast high level clouds and
also scattered/broken MVFR ceilings. The greater potential for
MVFR ceilings looks to be over Southeast Oklahoma and Northwest
Arkansas. During the day Thursday...MVFR ceilings look to lift
back to low VFR ceilings late morning and remain scattered/broken
through the TAF period. A small precip chance could be possible
near the end of the period...though with uncertainty for timing
will hold off mentioning this period.

..UPDATE...

DISCUSSION...
This morning a weak vorticity center was moving across far
Southern Kansas/Northern Oklahoma indicated by increasing mid/high
clouds over these locations. At the same time...the far outer
cloud bands associated with Tropical Storm Cindy were lifting
northward into far Southeast Oklahoma and Western Arkansas.
Between these two cloud decks...mostly clear skies were common
over the rest of Eastern Oklahoma and Northwest Arkansas.

Through this afternoon...scattered mid/high clouds should continue
to push through the CWA as the weak vorticity center drops
Southeast and Cindy makes its way northward. At the
surface...south to southeasterly winds and warm temperatures are
expected with high temperatures close to or a degree or so warmer
compared to yesterday. This is in result of the upper high
centered over the Southwest U.S. trying to expand into the
Southern Plains. Overall...the current forecast seems to have a
handle on things and will add just minor tweaks to
temp/dewpoint/sky/wind grids based on current trends and
observation for the morning update.
