Severe Weather Outbreak of May 8th

May 8th was actually the last of four consecutive days of severe weather across Northeast Kansas. A strong cold front front separated a cool dry air mass in the western high plains, from a warm moist air mass that had been in position for several days over the central plains.  On the morning of the 8th, the front stretched through central Nebraska and Kansas.  The front pushed east through the afternoon and evening hours. The lift provided by the front was accompanied bysurface heating to make conditions favorable for severe weather in northeast Kansas.
