Mesoscale Discussion 0883
NWS Storm Prediction Center Norman OK
0528 PM CDT Mon Jun 08 2020
Areas affected...northern Mississippi...northern Alabama...southwest
Tennessee
Concerning...Severe potential...Watch unlikely
Valid 082228Z - 090030Z
Probability of Watch Issuance...20 percent
SUMMARY...A recent uptick in convective intensity has been noted by
increased lightning and transient rotation within rain bands over
northern Mississippi/Alabama. A brief, weak tornado and strong winds
gusts are possible with these storms, but given the isolated severe
risk, a watch issuance is not anticipated at this time.
DISCUSSION...Convective cells generally moving northward within rain
bands of Tropical Storm Cristobal have exhibited transient rotation
per KGWX/KNQA/KBMX. Additionally, an increase in lightning has been
noted as breaks in cloud cover have helped destabilize and increase
updraft intensity with cooler cloud tops noted. Low-level shear and
observed VROT signatures of 10-20 knots indicate a brief, weak
tornado is possible with these storms. Strong wind gusts are also
possible. The threat will likely remain into the evening, although
it may begin to diminish once daytime heating wanes thus limiting
destabilization.
