.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
VFR conditions are expected through this forecast period. It`s
possible some patchy fog could develop at KFYV overnight, as
temperatures fall near the dewpoint. Confidence is not high enough
to add a visibility restriction.

.PREV DISCUSSION... /Issued 904 PM CST Wed Nov 22 2017/

..UPDATE...

DISCUSSION...
Mostly clear skies and light winds were common across Eastern
Oklahoma and Northwest Arkansas this evening in response to
surface high pressure pushing eastward through the region.

Overnight...the center of the surface high pressure will continue
to exit the CWA and shift eastward across Arkansas...with light
south- southwesterly winds returning for the CWA by early
Thursday morning. Also during the night...few to scattered
cirrus clouds currently across the Central Plains look to pass
through the CWA within the northerly upper level flow. Greater
potential for passing cloud cover looks to be across Northwest
Arkansas as thinning clouds over Eastern Kansas attempt to make
their way southeast.

The conditions mentioned above along with drier air at the
surface should aid temperatures during the night to fall into the
mid 20s to mid 30s across the CWA. For the evening update...have
added a few tweaks to hourly temp/sky/dewpoint grids based on
current trends and observations along with a couple adjustments to
low temps as a few locations were already nearing overnight lows.
Otherwise...the rest of the current forecast seems to have to be
handling well at this time.
