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 is forecasting an Enhanced Risk for
severe storms today and tonight, for northeast Missouri, and a
Slight Risk for the remainder of outlook area.
There will be two rounds of strong thunderstorms today. The first
will be this morning, with strong winds and heavy rain possible in
a line of storms moving through areas generally south of Highway
30.
Tonight, thunderstorms are possible over the entire area, but the
main threats will be found along and south of Interstate 80 where
damaging winds, large hail and torrential rainfall are most
possible.
Isolated areas of flash flooding are possible tonight, mainly
along and south of Highway 34, where soils are already wet.
.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY
A Slight Risk for severe weather has been issued by the Storm
Prediction Center on Friday, with the main threats being isolated
cases of large hail and severe winds. Several rounds of showers
and storms are expected through Friday, which leads to a
Slight Risk for Excessive Rainfall. Flash flooding will be a
growing concern as forecast confidence grows on the axis of
heaviest rain and timing.
Another day of heavy rain chances on Saturday, but will slowly
begin to die off in the evening. We have another Marginal Risk for
severe weather on Saturday, with the threats being isolated large
hail and severe gusts. Flash flooding threat will continue
through Saturday as well. After Saturday, daily chances for
showers and storms exist.
.SPOTTER INFORMATION STATEMENT...
Spotter activation may be needed for portions of the area on
Today and Tonight.
