506 AM EDT Fri Jul 05 2024
Areas affected...TX Panhandle into West-Central and Southwest OK
Concerning...Heavy rainfall...Flash flooding possible
Valid 050905Z - 051505Z
SUMMARY...Scattered to broken areas of convection will continue
this morning across areas of the TX Panhandle down into
west-central and southwest OK. Sufficiently high enough rainfall
rates coupled with slow cell-motions may foster at least localized
areas of flash flooding.
DISCUSSION...GOES-E IR satellite imagery shows broken areas of
cold-topped convection over areas of the TX Panhandle with the
activity tending to expand further in coverage off to the east
into areas of west-central to southwest OK.
The activity is focused along an instability gradient north of a
stationary front focused across areas of western and northern TX.
MUCAPE values of 500 to 1000+ J/kg are in place and there is
relatively divergent flow aloft working in tandem with a corridor
of stronger low-level moisture convergence to help facilitate the
development and expansion of the convection.
Some additional increase in the concentration of convection may
occur from the TX Panhandle down into southwest OK going through
the mid-morning hours, and the cell-motions are expected to be
rather slow which will favor some potential for locally excessive
rainfall totals.
The PWs are running about 2 standard deviations above normal over
the region, and rainfall rates are expected to locally reach 1 to
2 inches/hour with the stronger storms. The 00Z/06Z HREF guidance
favors some spotty totals going through mid-morning of 2 to 4
inches and this may result in a localized concerns for some flash
flooding.
