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

There is a slight risk for severe thunderstorms through this
morning with large hail the primary threat.

The Storm Prediction Center has a moderate risk for severe storms
this afternoon and evening along and to the southeast of a line
from Milledgeville, Illinois to the Quad Cities to Keokuk, Iowa.
An enhanced risk extends further to the north and west. Damaging
winds, large hail, and tornadoes are all possible with supercell
storms.

The most likely timing for scattered storms with this second
round, along and ahead of a cold front, is from the mid afternoon
through about 8 PM. The storms may be moving near 60 mph, so
there will be less time to react before they arrive.

Strong southwesterly winds may gust up to 45 mph late this
afternoon and evening behind the cold front. The windy conditions
will promote an elevated grassland fire danger through the
evening.

Area rivers are experiencing flooding. Please see the latest
Flood Statements and Flood Warnings for details. Additional
widespread rainfall through tonight could lead to renewed rises
on area rivers, including the Mississippi River, and possibly
higher crest levels into early next week.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

West to northwest sustained winds of 25 to 35 mph with gusts
up to 50 mph are expected on Sunday. Fire weather conditions will
remain elevated into Sunday evening.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed this afternoon and evening.
