Mesoscale Discussion 0452

1155 PM CDT Mon Apr 11 2022

Areas affected...Parts of east central Arkansas

Concerning...Severe Thunderstorm Watch 109...

Valid 120455Z - 120700Z

The severe weather threat for Severe Thunderstorm Watch 109
continues.

SUMMARY...A couple of strong storms persist, with some lingering
risk for hail into the 1-2 AM time frame.

DISCUSSION...Thunderstorm intensities have generally been weakening
the past hour or so, but a few stronger cores persist along the
western flank of a lingering convective cluster rooted within a zone
of enhanced lower/mid tropospheric warm advection.  One or two of
these, near and east-southeast of Searcy toward the Memphis area,
continue to occasionally produce at least small to marginally severe
hail.  This probably will continue to gradually diminish during the
next couple of hours, as short wave ridging builds northeastward. 
After 06-07Z, the primary warm advection driven storms may beco*e
focused near the crest of this ridging, across the Missouri Bootheel
vicinity into parts of western Kentucky and Tennessee, but it is not
clear that destabilization will beco*e supportive of an appreciable
increase in potential for severe hail.
