Mesoscale Discussion 2199
NWS Storm Prediction Center Norman OK
0959 PM CST Sun Nov 03 2024

Areas affected...much of southeast Oklahoma into far western
Arkansas

Concerning...Tornado Watch 703...

Valid 040359Z - 040600Z

The severe weather threat for Tornado Watch 703 continues.

SUMMARY...Isolated severe storms remain possible near the warm
front, but the overall risk has decreased co*pared to earlier this
evening. However, trends will need to be monitored for changes in
storm mode/structure.

DISCUSSION...A line of storms, mostly elevated, moved across eastern
OK and into western AR earlier this evening, outpacing the warm
front to the south. Recently, observations indicate the front is
making northward progress across southeast OK and into west-central
AR. In addition, radar shows new development near this boundary. A
rather tight temperature gradient still exists north of the
boundary, suggesting a limited region for storms to produce
tornadoes. However, this is also supporting lift and additional
cells may regenerate over the next several hours. Given effective
0-1 SRH around 300 m2/s2 along the boundary, a brief tornado will be
possible.
