Mesoscale Discussion 1110
NWS Storm Prediction Center Norman OK
0353 PM CDT Sun Jul 05 2020
Areas affected...Far eastern New Mexico into parts of the Texas
Panhandle
Concerning...Severe potential...Watch unlikely
Valid 052053Z - 052300Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated strong to severe storms will be possible
throughout the afternoon. A few severe hail stones and perhaps
damaging gusts may occur with the stronger storms.
DISCUSSION...Current mosaic MRMS radar data and visible satellite
imagery both depict a small uptick in convective coverage and
intensity over the past hour across far eastern New Mexico with
storms moving off of the higher terrain, and with storms developing
with a remnant southward moving MCV across the extreme northwest TX
Panhandle. Overall weak tropospheric winds suggest that most storms
should be relatively short lived. Nonetheless, modest mid-level
lapse rates exceeding 7.5 C/km suggest that some hail may accompany
a few of the more intense storms, and a severe stone or two cannot
be ruled out, particularly with the far eastern New Mexico storms
moving off of the higher terrain. Otherwise, a dry boundary layer
extending up to 700 mb (per latest RAP forecast soundings) and
associated 8+ C/km low-level lapse rates may promote efficient
evaporative cooling for a couple damaging gusts with the more
intense downdrafts in the Texas Panhandle.
