[html]MD 1292 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF THE TEXAS PANHANDLE INTO FAR WESTERN OKLAHOMA
Mesoscale Discussion 1292
NWS Storm Prediction Center Norman OK
0515 PM CDT Sat Jun 25 2022
Areas affected...portions of the Texas Panhandle into far western
Oklahoma
Concerning...Severe potential...Watch unlikely
Valid 252215Z - 260015Z
Probability of Watch Issuance...5 percent
SUMMARY...A few microbursts may acco*pany the stronger storms, with
an isolated severe gust possible. A WW issuance is not expected
given the very isolated extent of the severe threat.
DISCUSSION...A hot and unstable airmass has developed near a
stationary surface cold front, where storms have been gradually
increasing in coverage and intensity over the past few hours. On
both sides of the front, a deep, dry boundary layer extending up to
700-500 mb has supported the development of 9+ C/km 0-3 km lapse
rates. While tropospheric winds are weak, ample potential for
evaporative cooling in the deep and dry boundary layer is fostering
over 1500 J/kg DCAPE. As such, dry, high-based thunderstorms that
can manage to develop heavier precipitation cores may support an
isolated severe gust, and a 75+ mph gust cannot be co*pletely ruled
out should a more formidable microburst develop. Nonetheless, the
severe threat is expected to remain sparse, and a WW issuance is not
expected.
