.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
TSRA complex south of KMLC and KFSM...with VFR cigs to scatter out
at most sites this afternoon. TSRA chances return this evening to
NE OK. Cigs to lower to MVFR in thunder for a period of time as a
cold front moves north to south across the TAF tonight and
tomorrow morning. Outside of rain and thunder...VFR conditions
are expected to prevail for most of the TAF period.

.PREV DISCUSSION... /Issued 1022 AM CDT Sat Jun 17 2017/

DISCUSSION...
Small complex of severe storms continues to move south southeast
across east central OK this morning. Storms should begin to
weaken/dissipate towards the noon hour. Haver updated pops to
reflect current trends...mostly in raising pops across EC and SE
OK...as those locations will be in the likely track of the
complex. Have adjusted sky condition as well...and expect clouds
to thin by early afternoon...especially rain free locations across
northeast Oklahoma. Will leave heat headlines as they are for now
as much of the area that will remain rain free will not have
afternoon temperatures impacted by current cloud cover.

Updated ZFP/AFM/ZFP out shortly.
