Mesoscale Discussion 0391
NWS Storm Prediction Center Norman OK
0323 PM CDT Thu Apr 16 2020
Areas affected...Portions of South Central KS and Northwest OK
Concerning...Severe potential...Watch unlikely
Valid 162023Z - 162230Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated strong to severe storms capable of damaging wind
gusts and marginally severe hail may develop over the next 1 to 2
hours. A weather watch is not anticipated.
DISCUSSION...Afternoon visible satellite shows towering cumulus
becoming more pronounced along a surface trough/cold front running
from south central Kansas through the Oklahoma Panhandle into the
central Texas Panhandle. Surface analysis shows dewpoints have
increased into the lower to middle 40s concurrent with temperatures
in the mid to upper 70s F. Low-level convergence associated with a
weak wave cyclone and the approaching cold front should trigger
isolated thunderstorms by 22-23z. SBCAPE around 500 J/kg is present
with 50-55 kt of 0-6km bulk shear. This would support storm
organization with a couple high based supercells and clusters
capable of producing strong wind gusts and marginally severe hail.
Lack of greater boundary layer moisture suggests coverage will
remain too isolated for watch issuance.
