Mesoscale Discussion 0440
NWS Storm Prediction Center Norman OK
1255 PM CDT Thu Apr 10 2025
Areas affected...far southeast Missouri into parts of Kentucky and
Tennessee
Concerning...Severe potential...Watch possible
Valid 101755Z - 102030Z
Probability of Watch Issuance...60 percent
SUMMARY...Storms will increase in coverage and intensity through the
afternoon, with areas of damaging wind and sporadic hail expected.
DISCUSSION...Strong heating continues ahead of a cold front and
beneath very cold temperatures aloft with the shortwave trough. An
expanding mass of convection is already developing ahead of the
frontal surge over southeast MO, and this will develop rapidly
southeastward into KY and TN. Very steep lapse rates and moderate
deep-layer mean winds should support accelerating cold pools, while
straight hodographs and cold temperatures aloft support hail
production.
