Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

THUNDERSTORMS DEVELOPED IN THIS BAND OF INSTABILITY FROM NEAR
CHANUTE KANSAS TO SEDALIA MISSOURI.

HAIL...AS FREEZING LEVELS ARE LOW.

HIGH PRESSURE WILL SETTLE IN BEHIND THE FRONT TONIGHT...ALLOWING FOR
DECREASING CLOUDS. THIS HIGH WILL SHIFT EASTWARD ON WEDNESDAY WHICH

BACK INTO THE UPPER 60S ACROSS FAR SOUTHEAST KANSAS AND SOUTHWEST
MISSOURI...AND INTO THE LOWER 60S OVER CENTRAL MISSOURI.

A STRONG UPPER WAVE WILL PUSH INTO THE ROCKIES BY THURSDAY...CAUSING

ACROSS THE REGION. WITH BREEZY CONDITIONS...SHOULD BE ABLE TO MIX
THIS WARM AIR TO THE SURFACE. EXPECT TEMPERATURES RANGING FROM THE
