Mesoscale Discussion 0725
NWS Storm Prediction Center Norman OK
0215 PM CDT Mon May 25 2020
Areas affected...Most of Missouri
Concerning...Severe potential...Watch unlikely
Valid 251915Z - 252045Z
Probability of Watch Issuance...20 percent
SUMMARY...An isolated damaging wind gust is possible this afternoon
and evening, primarily across western Missouri.
DISCUSSION...A convective temperature of 80F from the 12Z KSGF RAOB
has been reached across much of Missouri with subsequent scattered
storm development. MLCAPE ranges from 2000 J/kg in eastern portions
of the state to 500 J/kg along the Kansas border. The best chance
for a few damaging wind gusts will be in western Kansas where
sufficient instability exists (1000-1500 J/kg) for robust updraft
growth and effective shear is around 30 knots per KSGF VWP to
promote some storm organization. In addition, 30 knots of flow at 1
km was observed on the 12Z SGF RAOB and is currently being sampled
near the same intensity on the KSGF VWP. This moderate flow above 1
km will promote a threat for strong 40-50 mph wind gusts with the
stronger cells which may be capable of isolated wind damage across
the region.
In eastern Missouri, widespread storms are ongoing amidst 2000 J/kg
MLCAPE. An isolated downburst threat will exist given the magnitude
of the instability, but storms will likely struggle to organize
given 15 to 20 knots of effective shear.
