.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Outflow boundary extends from far northeast Oklahoma southwest
through south central Oklahoma. Latest visible satellite show a
developing cumulus field along and south of the boundary. Expect
scattered storms to form by mid to late afternoon, possibly
affecting the AR terminals and KMLC. Any convection that does form
will contain gusty winds, which will be the main hazard with
collapsing storms.

.PREV DISCUSSION... /Issued 1032 AM CDT Sun Jul 23 2017/

..UPDATE...

DISCUSSION...
Outflow boundary has pushed south if I-44 late this morning and will
likely stall shortly.  Behind the boundary temperatures will be a few
degrees cooler than yesterday, therefore the excessive heat warning has
been downgraded to an advisory.  Dewpoints will remain high in this area
with afternoon heat indices around 105 degrees.  South of boundary, very
hot/humid conditions will persist with heat indices in the 105 to 112
degrees range.

Elevated showers/thunderstorms have started to dissipate.  Additional
thunderstorms will be possible along/near stalled boundary by early to mid
afternoon with storms pushing south into southeast Oklahoma/western Arkansas.
Damaging downburst winds/locally heavy rain will be possible in the stronger
storms. Updated forecast has been sent.
