Mesoscale Discussion 0391
NWS Storm Prediction Center Norman OK
1149 PM CDT Mon Apr 08 2024
Areas affected...Parts of north TX
Concerning...Severe Thunderstorm Watch 93...
Valid 090449Z - 090615Z
The severe weather threat for Severe Thunderstorm Watch 93
continues.
SUMMARY...Very large hail (golfball to baseball size) remains
possible with an ongoing supercell cluster. A brief tornado cannot
be ruled out.
DISCUSSION...Several supercells are ongoing at 0445 UTC to the
west-northwest of the Metroplex, with multiple cells having produced
golfball or larger sized hail (up to 3 inches in diameter) within
the last hour. While some cell interactions/mergers have been noted
with the northernmost cells, the two right-moving supercells ongoing
west of Mineral Wells and north of Fort Worth may be able to move
east-northeastward with minimal interference in the short term.
MLCAPE of around 2000 J/kg and effective shear of 45-55 kt will
continue to support supercell potential into the early overnight
hours, with very large hail (potentially 2-3 inches in diameter with
the strongest cells) as the primary threat, along with some risk for
localized severe gusts. Also, low-level flow has substantially
increased over the last 1-2 hours on the KFWS VWP, with 0-1 km SRH
increasing above 150 m2/s2. This could support a brief tornado
threat with the strongest right-moving cells, though relatively cool
near-surface conditions may mitigate this threat to some extent.
