Area Forecast Discussion
National Weather Service Tulsa OK
1215 AM CDT Tue Aug 27 2019

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
VFR to MVFR conditions are common across eastern Oklahoma and
western Arkansas early this morning with IFR conditions occurring
in the heavier thunderstorms. Will keep thunderstorms in the
TAF for the western Arkansas sites and KMLC until 11z at the
latest. Conditions improve during the day on Tuesday.

&&

.PREV DISCUSSION... /Issued 901 PM CDT Mon Aug 26 2019/

DISCUSSION...
Severe thunderstorms continue to develop in the vicinity of the
cold front that is advancing into northeast Oklahoma at this
hour. The front is currently near a Copan to Red Rock line.
The airmass just in advance of the cold front is still uncapped
with surface based cape running in the vicinity of 5000 J/kg.
Still the potential for a tornado over the next hour or so across
northeast Oklahoma if any of the discrete cells can stay rooted
along the surface boundary. As the cap strengthens over the next
few hours the activity will become more elevated as the cold front
spreads south. Still expecting a cluster of storms to develop overnight
across southern portions of the area as the low level jet increases.

Have made some adjustments to pops for Tonight to reflect current
trends in short-term model guidance.
