Multiple severe thunderstorms in the Hastings CWA. The algorithm lines up very well with where overshooting tops are observed on the visible and with our current SVR Warnings.

Had a cell form north of previous warning in Furnas county.  DVIL going up and time series lightning showed that cell contracting some (area went down with lightning holding steady).  Had an overshooting top few pixels in there as well.

Picture below shows 5 overshooting tops in or very near LOT CWA.

Initial thinking from radar data is that cell is starting to die down, but did have a few more upticks in overshooting top product.  Cell is no longer deviant in motion and got a new warning out to cover its trip back to the northeast.

We held off on issuing a warning for a cell moving into our CWA from Dawson County to the south where it produced 3″ diameter hail at 2305 UTC. For 3 reasons we held off.

1. the near storm environment had already been worked over by previous storms and radar showed stratiform rain falling in our area.

2. Prob Severe dropped from 96% at 2316 UTC to 41% at 2326 to 5% at 2330.

3. Lightning was not very impressive and diminished to near zero in the time series plot.

Tall cells continue, perhaps a turn to the right for the worst of the cell.

Lightning data fairly consistent, and not many strikes comparatively.

Continue to have an overshooting top and good DVIL with this line.  Had some stronger wind gusts and at an airport in Valley county (53 mph).  Near severe and extended the warning through the likely gust front area north of the higher DVIL storm.

Cell slowed down and strengthened before heading out of CWA.  Decided to go ahead and issue another warning to the CWA border.

UPDATE:  Had a 3″ hail report at 605 10 miles north of Lexington.  Images below are of DVIL from various radars near that time.

A rapidly growing storm developed over Putnam county IL and is slowly shifting eastward into La Salle county IL. The lightning jump algorithm has indicated as much as a 5 sigma increase with this storm. The CIMSS Prob Severe Model has indicated a high probability of severe storms over Putman and La Salle County.  See images of below, including the the severe thunderstorm warning issued for La Salle County.
