SVR9_UEX_4 SVR9_UEX_3 SVR9_UEX_2 SVR9_UEXHad 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.

Holding off

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.

Extending SVR eastward Charley

svr6_uex_2 svr6_uex

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.

Another SVR for Dawson County

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

SVR6_UEXUPDATE:  Had a 3″ hail report at 605 10 miles north of Lexington.  Images below are of DVIL from various radars near that time.
