NWS Storm Prediction Center Norman OK
0907 PM CDT Sat May 27 2017
Areas affected...northeastern TX Panhandle...northwest and far
Concerning...Severe potential...Severe Thunderstorm Watch likely
Valid 280207Z - 280300Z
Probability of Watch Issuance...80 percent
SUMMARY...A severe hail and severe gust risk will likely continue
southeastward into parts of northwest and far western Oklahoma.
DISCUSSION...Radar imagery (9-km CAPPI, MRMS MESH) shows intense
discrete storms over the OK and TX Panhandles moving southeast.
These storms will exit the southeastern portion of severe
thunderstorm watch #281 during the next 1-2 hours. Water-vapor
imagery shows a potent shortwave trough moving southeast across the
Sangre de Cristos and into the south-central High Plains. The
appreciable mid- to upper-level forcing for ascent will likely aid
in the storms longevity given favorable shear/buoyancy in place to
the north of a surface front. A measured 68 mph gust was recorded
at the Hooker, OK mesonet at 0150Z. Severe hail and severe gusts
will likely accompany these storms for the next couple of hours and
a new severe thunderstorm watch will probably be considered for
portions of far western and northwestern OK in an hour or so.
