This Hazardous Weather Outlook is for portions of north central
Illinois...northwest Illinois...west central Illinois...east
central Iowa...northeast Iowa...southeast Iowa and northeast
Missouri.

.DAY ONE...TODAY AND TONIGHT

The Storm Prediction Center has a slight risk for severe
thunderstorms over much of the outlook area. Scattered to numerous
thunderstorms should develop by late this afternoon and continue
through the evening hours. Given the high instability and strong
shear, isolated supercells should develop, especially west of a
Vinton to Keokuk, Iowa line. Very large hail to tennis ball size,
damaging winds to 70 mph and an isolated tornado or two are all
threats from these supercell storms. Any storms that congeal into
a line would be capable of at least 70 mph winds and large hail.

Area rivers are experiencing flooding. Please see the
latest Flood Statements and Flood Warnings for details.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

Thunderstorms will be possible again on Wednesday night through
Thursday night, with chances for widespread thunderstorms on
Thursday and Thursday night. At this time the threat for strong to
severe storms is low, but storms could produce small hail, gusty
winds, and localized heavy rains.

Heat and humidity will develop across the outlook area for Friday
through Monday with heat indices expected to reach the mid and
upper 90s in some areas.


.SPOTTER INFORMATION STATEMENT...

Activation of spotters and amateur radio networks will likely be
needed from 3 pm to midnight this afternoon and evening.
