..UPDATE...

DISCUSSION...
The upper level closed low remained over the Northern Plains this
evening with an associated upper level trof axis extending
southwest through the Central and Southern Plains. Ahead of this
axis...across Eastern Oklahoma and Northwest Arkansas...mostly
clear skies and westerly winds were begin observed.

Overnight tonight...the upper level trof axis will continue to
shift east southeast through the Central/Southern Plains and into
the CWA by early morning Wednesday. An increase in cloud cover
from west to east across Northeast Oklahoma and Northwest
Arkansas will be possible as the trof axis moves into the region.
Mostly clear conditions should persist over Southeast Oklahoma
into West Central Arkansas.

Drier air spreading across the region behind the surface frontal
boundary...that moved through today...will allow for low temps to
be slightly cooler for most locations tonight. Thus...upper
20s/around 30 degrees will be possible for the normal cool
spots/valley locations with low to mid 30s expected elsewhere for
the CWA. In response...have adjusted temps/dewpoints/sky grids to
account for latest trends/observations for the evening update. The
rest of the forecast seems to be in good shape at this time.
