CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.

.PREV DISCUSSION... /Issued 314 PM CDT FRI AUG 5 2016/

DISCUSSION...
Lingering mid/high clouds, across portions of northeast Oklahoma,
have provided some relief from the heat north of Interstate 44
this afternoon. Further south, heat indices in the 105 to 107
degree range are common where a heat advisory is in effect. A relatively
moist and unstable airmass remains in place across northeast Oklahoma
and northwest Arkansas. Scattered showers and thunderstorms will
be possible this afternoon/evening with precipitation chances
continuing through the overnight hours as a weak frontal boundary
moves into the area.

Scattered showers/thunderstorms will remain possible on Saturday
as frontal boundary stalls near the Interstate 40 corridor. Along
and south of front heat indices from 105 to 108 degrees are
anticipated and will therefore go ahead and issue a heat advisory
for aforementioned area. The advisory may need to be expanded a
little further north depending on exact frontal position and
overall coverage of precip/clouds into Saturday morning.

Hot/humid conditions will generally persist into next week as
upper high remains over the southern plains. Low precipitation
chances will also continue, mainly during the afternoon and
evening hours in association with peak heating.
