Supercell thundestorms developed along the Missouri/Kansas border during mid-afternoon hours Tuesday, March 24 as a vigorous shortwave trough tracked into northern Missouri and an accompanying surface low and attendant dry line pushed into southern Missouri. Storms moved rapidly to the east and diminished in the eastern Ozarks by mid evening Tuesday. The storms were efficient hail producers with many reports. At 33 hail reports were received with the largest hail the size of ping pong balls.  The storms produced a few wall clouds with one readily apparent in the Springfield area. 

Here is map depicting the storm reports across the area.
