Mesoscale Discussion 1968
NWS Storm Prediction Center Norman OK
0442 PM CDT Wed Aug 21 2024
Areas affected...portions of southern Arizona
Concerning...Severe potential...Watch unlikely
Valid 212142Z - 212315Z
Probability of Watch Issuance...20 percent
SUMMARY...A few instances of severe hail/wind gusts are possible
through the remainder of the afternoon and evening. The severe
threat should remain isolated, and a WW issuance is not anticipated.
DISCUSSION...Pulse-cellular storms have been percolating in
intensity over the past few hours with approach of peak afternoon
heating. These storms are developing atop a low-level airmass
characterized by steep low-level lapse rates. Given relatively weak
vertical wind shear in place, storms will likely remain
pulse-cellular in nature, though a few multicell clusters are
possible. Severe gusts are the main threat, though a couple
instances of large hail may also accompany the strongest,
longest-lived storm cores.
