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


Rounds of moderate to heavy rainfall today into this evening, then
again spreading up from the south late tonight, will lead to
substantial rainfall amounts across much of the Outlook area by
Sunday morning. General 24 hour rainfall amounts by Sunday
morning are expected to range from three quarters of an inch, to
just under 2 inches. The higher rainfall amounts will occur along
and south of the I80 corridor. This amount of rain will produce
elevated levels on small creeks and streams, ponding of water in
urban areas, on roads, underpasses, as well as other poor drainage
areas and low lying spots.

Scattered non-severe thunderstorms are expected to be embedded in
the rain mainly along and south of the I-80 corridor this
afternoon and into the evening. Cloud to ground lightning, locally
heavy downpours, and small hail will be the main threats from
these storms.

Area rivers are experiencing flooding, or forecast to go into
flood. Please see the latest Flood Statements and Flood Warnings
for details.


Widespread rain, will continue Sunday morning through Sunday
afternoon, with a few rumbles of thunder possible. Over the 2 day
period, widespread rainfall amounts of 1 to 3 inches are expected.
There are river flood watches and warnings for many area tributary
rivers and the Mississippi River for this rain forecast.  Flash
flooding is not expected to be a threat until Sunday afternoon and
evening, when thunderstorms are expected to bring spotty intense
rainfall.  Those with interests along area rivers, streams and
creeks should check back for updates through the weekend.

Isolated severe storms are possible Sunday afternoon and evening,
but confidence remains low. If severe storms occur, the main threats
would be damaging winds, localized flash flooding, and possibly a


Spotter activation is not anticipated today or tonight.
