Severe Weather in the Plains

Severe Weather Update

We do have a few areas that we are now watching this afternoon.  All of these have the potential to produce damaging weather as we head on through the rest of the day.  First, areas #1 and #2:
Area #1 is a few showers and thunderstorms that have developed out in Central Wisconsin.  They have the potential to become supercells, or rotating thunderstorms, as they mature due to the favorable environment.  However, because they are already in a linear formation, that probability is going down.  If they can strengthen, and have a favorable environment, potential exists for a derecho, as evidenced by this excerpt from the NWS in the Quad Cities Forecast Discussion:
SHORT WAVE COMBINED WITH FRONTAL
BOUNDARY AND HIGH CAPES SUGGEST POTENTIAL FOR EXPLOSIVE DEVELOPMENT
OF THUNDERSTORMS IF CAP BREAKS. IF THIS SCENARIO PANS OUT THEN A
DESTRUCTIVE DERECHO WITH WINDS OVER 100 MPH IS CERTAINLY POSSIBLE.
This could be a very interesting night if that pans out.  It would hit areas affected by the July 11 derecho of 2011.
Stay tuned on that one.  Area #2 is a squall line that has formed.  It should maintain its intensity, capable of damaging winds.  Stay tuned!
