Looks like they just issued another t-storm watch for central IA until
6am.

Nice line of training cells, most of which are currently warned.

SBCAPEs of around 2000 with 4000 j/kg to the West should keep them
well fed for sometime to come.

Many reports of truck/cars blown off the road and damage to buildings
from straight line winds.

Golf ball size hail being reported as well.
Update: spotters reporting baseball size hail (2.75") with the
cell that passed through Boone county.

Agreed. A very serious flooding situation is developing too with the intense precipitation rates, and the training.. The same area from DMX to IRK have been getting pounded all day. Large hail indicators on nearly all the cells..

Many flash flood warnings issued now in Central IA.
The line has been back building over the last hour or
so. It has reduced in intensity but still had a cell
that is/was showing a nice small hook to it and was tornado warned
in the Northern section of the line NW of DMX.

SBCAPEs have dropped substantially into the 1000 - 1500 j/kg range.
Hail markers have also dropped. This is cell C6 on DMX and still shows
some wicked VILs though.

I suspect this line will continue to weaken as the morning
wears on. It's had its fun for now.
