Areas affected...western Oklahoma...far eastern Texas Panhandle

Concerning...Severe Thunderstorm Watch 253...

Valid 042337Z - 050130Z

The severe weather threat for Severe Thunderstorm Watch 253
continues.

SUMMARY...A cluster of storms is beginning to congeal into a line
across western Oklahoma. These storms will continue moving southeast
with the potential for damaging winds and large hail.

DISCUSSION...Storms with a history of severe wind including reports
of 70 and 80 mph and large hail (1 inch) are moving southeast across
western Oklahoma. Storms are beginning to form a more coherent line
with some evidence of an increasing rear inflow jet developing
behind the center of the line. Surface temperatures of 95-105 F and
a deep, well mixed boundary layer with surface dewpoint depressions
of 35-50 F are likely to contribute to efficient mixing of strong to
damaging wind gusts to the surface. If the line continues to
organize, the threat for damaging winds will increase in the short
term. Large hail will also remain possible. These storms will begin
to weaken after sunset, but the severe threat will remain for the
next 2-4 hours. As these storms begin to collapse later tonight,
strong winds could emanate outward from the cluster with heat bursts
possible.
