Severe Thunderstorms, February 28, 2007

Thunderstorms developed across southeastern Kansas during the afternoon hours of February 28, 2007.  A low pressure system at the surface was located over northeast Kansas during the afternoon hours on Wednesday.  A secondary, stronger low deepened over the Texas panhandle throughout the afternoon hours. Southerly wind flow on the southeast side of the lows drew warm, moist air from the south northward, and set the stage for severe weather development later in the day.  A warm front stretched from northeast Kansas through central Missouri, and a dry line extended from the low, southward into north central Oklahoma .  Storms initiated along the dry line after 4pm, and moved in a northeastwardly direction.  The storms became severe, and began to drop hail in the NWS-Topeka County Warning Area (CWA) just after 6pm (Coffey County).


Hail up to the size of golfballs (1.75” in diameter), wind gusts up to 60mph, and tornadoes were all reported to have occurred in the NWS-Topeka CWA.  A map depicting the storm reports in the NWS-Topeka CWA can be found below.
