Iowa...west central Iowa...east central Nebraska...northeast
Nebraska and southeast Nebraska.

.DAY ONE...This Afternoon and Tonight

Severe thunderstorms will be possible this afternoon and evening,
generally along and southeast of a line from Columbus, Nebraska to
Sioux City Iowa. The main timeframe for severe storms will be from
4 pm through midnight. All modes of severe weather could occur,
including large hail, damaging winds, and an isolated tornado or 
two. Localized heavy and possibly flooding rains could also occur
which could lead to flash flooding if multiple storms move over 
the same locations.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Hot temperatures in the mid to upper 90s are expected both Sunday
and Monday. Afternoon heat index values both days could range 
from 98 to 103, leading to an elevated risk of heat illness. 
 
Sunday evening through Monday evening will feature another chance
for strong storms mainly over northeast Nebraska. 

And more storms are in the forecast Tuesday afternoon and night 
as a frontal boundary moves into the region. These storms could
also be severe, along with potentially flooding rain. 

The active weather pattern remains in the area with a daily 
chance for storms from Wednesday through Friday. 

.SPOTTER INFORMATION STATEMENT...

Spotter activation could be needed for some areas late this
afternoon through the evening.
