Mesoscale Discussion 0670
NWS Storm Prediction Center Norman OK
0354 PM CDT Fri May 22 2020
Areas affected...Southeast Nebraska and Northeast Kansas
Concerning...Severe potential...Watch unlikely
Valid 222054Z - 222230Z
Probability of Watch Issuance...5 percent
SUMMARY...A brief tornado is possible this afternoon/evening in
southeast Nebraska and northeast Kansas.
DISCUSSION...Several bands of shallow convection have developed in
the proximity of the upper low/surface MCV in northern Kansas.
Low-level streamwise vorticity is enhanced in this region with 0-1
SRH around 100 to 150 m2/s2. Low-level flow is mostly veered where
instability has increased to the east of the circulation. However,
there may be some brief overlap between the better instability and
favorable wind profile. The limited moisture/instability will likely
be the limiting factor to a greater threat.
