May 14 thunderstorms

Wednesday, 15 May 2013 | Weather

The local National Weather Service – Sullivan website is quite good about posting retrospectives on events of meteorological note, so it’s often a good place to look for analysis if something’s occurred that you find particularly noteworthy or unusual. But the site also often presents interesting debriefings on events that might otherwise have seemed mundane.

The thunderstorms that formed west of Madison and moved over the area on Tuesday evening (May 14th) didn’t seem particularly unusual to most of us — they were in a declining state as they moved in, so by-in-large, they weren’t even terribly strong.

But dying thunderstorms can produce an unusual phenomenon called “heat bursts,” and the NWS-Sullivan article about this in regard to the May 14th storms is typically fascinating and instructive.
