Heat Burst/Wind Damage in Wisconsin

mad    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.

    Wow… You know what’s strange, I was out last night at 10PM when we got a small shower here in BC. I was sitting in my truck waiting for my girlfriend to get out of work and felt a gust of warmer than usual air. I noticed it being a little warmer out after that, and it made me think of “heat bursts” and how rare they are.

    Quite the coincidence. Wish I was in Holland to experience that last night.

      I thought it was the warm front passing through, as there was a warm front being analyzed nearby on the surface charts. The wind shifted after a thunderstorm had passed, and it got quite breezy and warm. The dew point did not drop like it usually does with heat bursts, but we certainly could have had some of that heat burst air after the warm front had passed. Holland and South Haven certainly had much more pronounced warming last night than Muskegon and Grand Rapids.

    After reading this, something I thought was just me being tired was actually happening. Upon returning from an emergency call, I remember thinking if felt warmer than when I had left my house. It’s interesting seeing the hourly observations at the KBIV location (3 miles to my east).
