Heat Burst/Wind Damage in WisconsinMay 15th, 2013 at 9:58 pm by Bill Steffen under Bill's Blog, Weather
Thanks to Cort for noticing the heat burst that occurred in Wisconsin yesterday PM. Here’s the write up from the NWS in Milwaukee (Sullivan WI). A decent heat burst is a rare event and even rarer in this area (it would be more common in the High Plains). Our weather parameters were more like the High Plains yesterday PM with dry air near the ground and the instability well above ground (above 3,000 feet). The showers and thundershowers produced very little rain. In West Michigan, the most rain was 0.10″ at Hart. Rainfall amounts in Wisconsin were also meager: 0.02″ at Milwaukee and Sullivan and 0.01″ at Waukesha (where there was some damage). We had a “heat burst” here in W. Michigan as well. The wind came up to 38 mph in Holland (regional airport) and at S. Haven. The temperature at Holland went from 65 at 10:53 PM to 69 at 11:53 PM to 78 at 12:53 PM and peaked at 80 shortly after 2 AM. At S. Haven the temperature also jumped up to the upper 70s. The sun didn’t warm up the air at that time of night and it wasn’t air coming across Lake Michigan (the mid-lake buoy didn’t get past the mid 50s).
Also – injuries in the Texas tornadoes tonight.
