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...TONIGHT

Scattered to clusters of strong to severe storms will move across
portions of the Outlook Area through this evening. All modes of
severe weather will be possible with this evening activity.

These storms will also produce heavy rainfall at high rates. In
areas that receive repeated storm activity, there will be the
chance for flash flooding. The higher potential for this appears
to be south of Interstate 80. A Flood Watch is in effect through
Thursday morning for areas generally south of the Highway 30
corridor.

Some area rivers will experience substantial within bank rises
from the bouts of heavy rainfall. A few may even approach flood
stage through the end of the week.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

On Thursday, two more rounds of storms will be seen across the
area; the first in the morning and the second in the afternoon and
early evening. The Storm Prediction Center has an Enhanced, level
3 out of 5, risk for the area.

All modes of severe weather will again be possible on Thursday.
Individual supercells will have the capability to produce very
large hail and strong tornadoes especially during the afternoon
due to a strong low pressure system moving through the area. Storm
cells that evolve into bowing segments or lines may produce
damaging winds of 70 to 80 plus mph in the strongest storms.

Heavy rainfall will again be a risk with the storms on Thursday.
With the ground primed from the heavy rain on Wednesday, a flash
flood risk will continue on Thursday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is likely both this evening and on Thursday.
