Mesoscale Discussion 0719
NWS Storm Prediction Center Norman OK
0843 PM CDT Sun May 24 2020
Areas affected...Northwest Texas...Southeast Texas
Panhandle...Western Oklahoma
Concerning...Severe Thunderstorm Watch 219...
Valid 250143Z - 250345Z
The severe weather threat for Severe Thunderstorm Watch 219
continues.
SUMMARY...Wind damage and hail threat will continue as a line moves
eastward across northwest Texas and western Oklahoma. The threat
should persist for another hour or two but should decrease as an
outflow boundary moves northwestward across western Oklahoma.
Although watch issuance is unlikely, a local extension can not be
ruled out.
DISCUSSION...Latest radar shows a line of storms from far northwest
Oklahoma into the eastern Texas Panhandle and then
south-southeastward into west-central Texas. These storms are
located along and just west of an axis of strong instability where
the RAP is analyzing MLCAPE in the 2500 to 3500 J/kg range. This
line will continue to move into the strong instability over the next
couple of hours maintaining a wind damage and hail threat. However,
an outflow boundary is evident on radar imagery, moving
northwestward across southwestern Oklahoma. This outflow boundary
will eventually merge with the convective line resulting in a
decrease in the severe threat later this evening. Although a local
extension can not be ruled out, new weather watch issuance is not
expected.
