Area forecast discussion, Oct 5, 12:31 AM CDT, 2 hours 42 minutes before

Area Forecast Discussion
National Weather Service Tulsa OK
1231 AM CDT WED OCT 5 2016

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Mainly MVFR to VFR conditions can be expected through the period
with showers and thunderstorms affecting many of the TAF sites
during the overnight hours.

&&

.PREV DISCUSSION... /Issued 938 PM CDT TUE OCT 4 2016/

..UPDATE...

DISCUSSION...
Convection originating across central OK has begun to trend
downward as boundary layer begins to stabilize. However there
remains synoptic level forcing to the west and sufficient deep
layer shear remains in place to support strong to marginally
severe weather as convection continues to spread into NE OK.
Updated forecast will account for short term precip trends with
remainder of forecast on track.
