Mesoscale Discussion 0164
NWS Storm Prediction Center Norman OK
0427 AM CDT Wed Mar 11 2020
Areas affected...southeastern Kansas/northeastern
Oklahoma/southwestern Missouri/northwestern Arkansas
Concerning...Severe potential...Watch unlikely
Valid 110927Z - 111130Z
Probability of Watch Issuance...20 percent
SUMMARY...A convective cluster will continue spreading
east-southeastward out of southeastern Kansas toward the Ozark
Plateau, with limited risk for marginally severe hail and locally
strong/gusty winds. WW issuance continues to appear unlikely to be
required in the shorter term.
DISCUSSION...Convection over the past 1 to 2 hours has evolved from
a more initially cellular mode to more of a loosely organized
cluster, with some hints that a weak convective mesolow may be
evolving near the southeastern Kansas/southwestern Missouri border.
Given the transition toward a loosely linear mode, risk for hail in
excess of 1" has diminished, with only limited risk for a marginally
severe hailstone apparent at this time.
Meanwhile, the airmass downstream from the convection remains
characterized by modest instability atop a stable surface-based
layer. As such, potential for severe-caliber wind gusts appears to
remain low. However, a few strong wind gusts capable of minor tree
damage cannot be ruled out, as storms spread east-southeastward into
southern Missouri/northern Arkansas. Overall, potential for severe
weather remains limited, and watch issuance remains unlikely in the
short term.
