Mesoscale Discussion 0809
NWS Storm Prediction Center Norman OK
1018 PM CDT Tue May 17 2022
Areas affected...Eastern Kansas into western Missouri
Concerning...Severe Thunderstorm Watch 237...
Valid 180318Z - 180415Z
The severe weather threat for Severe Thunderstorm Watch 237
continues.
SUMMARY...The damaging wind threat is increasing along and south of
I-70 in eastern Kansas and western Missouri.
DISCUSSION...A mature bow has developed near Topeka and is moving
east-south-eastward toward the western/southern suburbs of Kansas
City. The 00Z TOP RAOB showed a very unstable airmass (~4000 J/kg
MLCAPE) and effective shear around 45 knots with steep mid-level
lapse rates. This is an environment favorable for damaging winds
gusts with significant (75+ mph) wind gusts possible at the apex of
the bow where a rear-inflow jet has started to develop.
In addition, the 00Z RAOB and the 03Z EAX VWP show significant
low-level turning which could support some mesovorticies capable of
significant wind damage and/or a brief tornado.
