Expect severe weather, heavy rainfall tonight

Jun 03, 2014

The National Weather Service in the Quad Cities has issued a hazardous weather outlook and flash flood warning for portions of north central Illinois, northwest Illinois, west central Illinois, east central Iowa, northeast Iowa, southeast Iowa, including Jefferson County, and northeast Missouri.

A storm system moving quickly out of the Rockies today will interact with moisture streaming northward from the Gulf of Mexico to generate thunderstorms capable of producing heavy rain and severe weather in the region this evening and overnight.

The area most at risk from these hazards is generally from around the Quad Cities to points west and south.

Thunderstorms are expected to begin initially as a severe weather producer during the evening hours, then evolve into a heavy rain threat overnight as the low-level jet fires up and the atmosphere moistens.

Large hail and possibly tornadoes in proximity to the low-level boundary in southern Iowa are the initial main threat.

As the system evolves overnight, heavy rain and wind become the main threats.

Heavy intense rainfall from thunderstorms could tally as high as four or five inches in some locations and produce flash flooding. Rainfall could cause flash flooding of small creeks and streams as well as flooding on area rivers.

As of this morning, it looks more like heavy rain is the threat in this area with the wind threat mostly further south in Missouri and central Illinois.

Thunderstorms with locally heavy rainfall will diminish Wednesday morning with only a chance of storms during the afternoon.
