Mesoscale Discussion 1569
NWS Storm Prediction Center Norman OK
0441 PM CDT Sat Jul 23 2022

Areas affected...Parts of NE...southeast SD...and far northwest IA

Concerning...Severe potential...Watch possible 

Valid 232141Z - 232245Z

Probability of Watch Issuance...60 percent

SUMMARY...Isolated to scattered severe storms capable of large hail
and severe gusts will increase in coverage this afternoon. A watch
issuance is possible.

DISCUSSION...c*nvective coverage is expected to gradually increase
along a cold front extending across parts of Nebraska this
afternoon. Ahead of the front, lower 70s dewpoints and steep
midlevel lapse rates are contributing to moderate to strong surface
based instability and minimal convective inhibition. In addition,
35-45 kt of effective bulk shear oriented oblique to the surface
front will support embedded organized updrafts along/ahead of the
front capable of isolated large hail and severe gusts. Trends are
being monitored for a possible watch issuance.
