Grand Island Heat Bursts

Posted: 12 Jun 2013 05:33 AM

Portions of southcentral Nebraska experienced an intense heat burst event during the early morning hours on Tuesday. The featured chart presents one minute interval observations from the Grand Island, Nebraska ASOS. Heat bursts are caused by decaying thunderstorms driving very warm and dry air to the ground. The classic signature is a rapid rise in temperature along with a rapid drop in dew point. The chart appears to show four heat burst events with the two after 5 AM being extremely intense as the temperature goes from the 70s to 100 degrees in a few minutes. These events tend to also bring gusty winds with some gusts over 50 mph reported in the area.

Good = 112
Bad = 9
