Mesoscale Discussion 0252
NWS Storm Prediction Center Norman OK
0602 PM CST Fri Mar 03 2023

Areas affected...Portions of southeast Ohio and far northern West
Virginia

Concerning...Severe potential...Watch unlikely 

Valid 040002Z - 040100Z

Probability of Watch Issuance...5 percent

SUMMARY...A marginal wind/tornado threat will continue for another 1
to 2 hours before dissipating.

DISCUSSION...Weak instability, driven by temperatures in the upper
50s to near 60 across southeast Ohio will provide enough buoyancy
for occasional strong winds along a line of storms in southern Ohio.
In the presence of a strong kinematic wind field, damaging wind
gusts and perhaps a brief tornado are possible. However, this threat
will weaken considerably over the next 1 to 2 hours as the sun sets
and the boundary layer cools.
