MD 2275 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR SOUTHEAST OKLAHOMA AND FAR NORTHEAST TEXAS.
Mesoscale Discussion 2275
NWS Storm Prediction Center Norman OK
0258 PM CST Mon Nov 20 2023
Areas affected…southeast Oklahoma and far northeast Texas.
Concerning…Severe potential…Watch unlikely
Valid 202058Z – 202200Z
Probability of Watch Issuance…5 percent
SUMMARY…Isolated large hail possible this afternoon across
southeast Oklahoma and far northeast Texas.
DISCUSSION…A pocket of destabilization has occurred near a surface
low in southeast Oklahoma where temperatures have warmed into the
upper 70s with dewpoints in the mid to upper 50s. Low-level
convergence associated with this surface low, combined with cool
temperatures aloft and and the aforementioned instability has
provided an environment favorable for scattered storm development
this afternoon. Very strong mid-upper level flow is supporting
rotating updrafts. Therefore, a few of these cells may be capable of
isolated large hail for the next few hours. This threat will persist
for a few hours and wane after sunset with the loss of daytime
heating.
