CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Cold front is currently working its way through the terminals this
morning with showers and thunderstorms dissipating as drier
airmass moves in. IFR and MVFR cigs will give way to VFR behind
the front later this morning and prevail through the remainder of
the TAF period. Winds will remain light as high pressure
encompasses the area.

.PREV DISCUSSION... /Issued 358 AM CDT Wed Aug 23 2017/

DISCUSSION...
Numerous showers and isolated thunderstorms continue early this
morning from northwest Arkansas into southeast Oklahoma. The true
cold front is along the I-44 corridor marked by noticeably drier
air and this will continue southward today. Precip coverage is
expected to diminish through the morning ahead of the front
however low precip chances will continue through the afternoon for
southern locations and not end until the drier air pushes through
the entire forecast area this evening.

Post frontal conditions will be seasonably cool and dry compared
to normal late August values. Attention by Friday through the
weekend will largely focus on the western Gulf of Mexico and
eventual landfall of a strengthening tropical cyclone. Data
continue to suggest this system will make little northward
progress as northwesterly flow dominates the central Plains. The
forecast will maintain low precip chances spreading into southeast
Oklahoma over the weekend and then a broad low chance for late in
the weekend as a stronger wave passes in the northwesterly flow.
However with the low level flow across the area influenced by the
tropical cyclone and maintaining the drier E-NE direction any
precip chances are likely to remain low and amounts rather light.
Temps look to remain near persistent from late week into early
next week.
