Two Days Of Severe Thunderstorms

The preliminary maps of severe thunderstorm reports for April 27th and 28th are shown above - well over 600 reports of severe events are indicated. A number of the tornadoes were destructive, producing many injuries and deaths. It is interesting, and perhaps worthy of study once final reports are documented, that supercells producing tornadoes were scattered from Nebraska to Alabama on Sunday, but were mostly confined to a narrow corridor across Mississippi and Alabama on Monday.

Meanwhile, the large cyclone over the Central Plains has brought yet another late spring snowstorm to the northern Plains. Web cam view below is from I-90 at Spearfish, South Dakota, in the northern Black Hills, this morning.
