MD 1030 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR NORTH-CENTRAL ALABAMA

Mesoscale Discussion 1030
NWS Storm Prediction Center Norman OK
0711 PM CDT Sat Jun 27 2020

Areas affected...North-central Alabama

Concerning...Severe potential...Watch unlikely 

Valid 280011Z - 280115Z

Probability of Watch Issuance...20 percent

SUMMARY...A brief/weak tornado threat will persist through 01Z.

DISCUSSION...A cluster of storms has interacted with an outflow
boundary from earlier convection across northern Alabama. This has
resulted in multiple reports of weak tornadoes. The environment is
not overly favorable for a sustained tornado threat per KBMX and
KHTX VWP, and base velocity from KHTX shows very weak rotation with
these cells. However, a continued threat for brief/weak tornadoes
may persist through 01Z as low-level vorticity along this outflow
boundary is stretched vertically. Boundary layer cooling after 01Z
should bring an end to this short duration threat.
