Mesoscale Discussion 0445
NWS Storm Prediction Center Norman OK
1243 PM CDT Mon Apr 11 2022

Areas affected...northeastern Oklahoma east-northeastward across the
Ozarks

Concerning...Severe potential...Watch unlikely

Valid 111743Z - 111945Z

Probability of Watch Issuance...20 percent

SUMMARY...Elevated storms -- posing a local risk for severe-caliber
hail and perhaps gusty winds -- will continue to expand across the
Ozarks vicinity.  WW issuance is not anticipated at this time.

DISCUSSION...Latest radar loop shows convection increasing in
coverage/intensity across southeastern Kansas/northeastern
Oklahoma/southwestern Missouri, atop a cool/stable boundary layer.
The convective increase is occurring as large-scale ascent --
associated with a mid-level short-wave trough now crossing eastern
Oklahoma and eastern Kansas -- spreads atop the region per recent WV
imagery. 

With rather steep lapse rates aloft supporting ample elevated cape
for occasionally vigorous updrafts, and aided by strong (60 kt)
west-southwesterly mid-level flow, a few sustained storms may prove
capable of producing hail in excess of an inch in diameter.  At this
time however, it appears that risk will remain local/isolated, and
thus not requiring WW consideration over the next hour or two.
