Showers with 3 claps of thunder just moved through.  Seemed I was in the "meat" of the line up here.  Total rainfall from this line was .007".  Sun breaking through again.  Temp down to 71F Dew up to 67F.

 

I see the NWS has my area in a severe thunderstorm warning, don't get it, line is very weak in this area.....
