-- Changed Discussion --CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Previous forecast generally on track this evening. As upper wave
approaches from the northwest tonight, scattered areas of rain
will begin to develop over eastern Oklahoma, spreading into northwest
Arkansas Friday morning. Ceiling heights will continue to lower
at most TAF sites through the day with MVFR conditions likely by
afternoon, including reduced visibilities in the heavier rain
showers. Went ahead and added thunder chances to MLC late tonight
into Friday morning given the modest elevated instability that
develops during this time.-- End Changed Discussion --

DISCUSSION...
The latest data supports the going forecast with only a slow
eastward progression of rain chances overnight due to an
increasingly dry low level airmass the farther east you go.
Isolated thunderstorms remain possible across parts of east
central and southeast Oklahoma later tonight, but nothing strong
is expected. The current forecast is on track, but will resend
the zones to clean up some of the temporal wording.-- End Changed Discussion --
