Mesoscale Discussion 0973
NWS Storm Prediction Center Norman OK
1120 AM CDT Sun May 26 2024
Areas affected...portions of eastern Indiana...northeastern
Kentucky...western and central OH...western West Virginia
Concerning...Severe potential...Watch likely
Valid 261620Z - 261745Z
Probability of Watch Issuance...80 percent
SUMMARY...The severe threat is increasing across portions of the OH
Valley ahead of ongoing storms. Damaging gusts appear to be the main
threat, though a couple of QLCS tornadoes are also possible. A WW
issuance will be needed in the next hour or so.
DISCUSSION...A QLCS, with a recent history of damaging gusts,
continues to progress eastward toward a destabilizing airmass.
Surface temperatures are warming to over 80 F amid upper 60s F
dewpoints, boosting MLCAPE to 2000 J/kg in spots. In additions,
40-50 kts of effective bulk shear are in place, with the shear
vectors oriented roughly normal to the eastward progressing QLCS. As
such, damaging gusts (some exceeding severe limits) should accompany
this QLCS downstream, and a couple of line-embedded tornadoes also
cannot be ruled out. A WW issuance will be needed in the next hour
or two to address the impending severe threat.
