Heavy Rainfall and Flood Watch Across Midwest
A flood watch is currently active in far northern Illinois, adjoining parts of Wisconsin, the eastern half of Iowa, and the top half of Missouri. This flood watch, which does not affect the entirety of any of the stated states, is associated with heavy to excessive rainfall expected over the weekend into early next week.
The weather forecast for urban areas in these regions suggests a heightened risk of flash flooding, especially across eastern Iowa and nearby regions. The flood watch is not related to the forecasted rainfall amounts, which could be between one to three inches on Sunday, or the risk of urban flooding in specific areas.
Recent average temperatures have been near or slightly above normal for these areas, contributing to convective activity that can enhance rainfall intensity. The risk of flash flooding is slight on both Sunday and Monday, but most vulnerable areas to flash flooding are urban areas, small streams, washes, and roads.
While the risk for severe weather on Sunday is at the low end, no specific warnings for tornadoes or other severe weather were found for this period. The National Weather Service rates the chance of 60 mph winds as level one out of five.
The flood watch is active in the northern regions of the mentioned states and is not related to the risk of 60 mph winds or severe weather. The cooler temperatures associated with this rain system have brought daytime temperatures in the mid 80's.
The longer-range outlook shows no strong precipitation trend changes after this weekend, so the heavy rainfall threat is concentrated primarily Sunday through Tuesday. Residents are advised to monitor local National Weather Service updates for evolving conditions.
Weather-forecasting models predict heavy rainfall throughout the weekend in the Midwest, particularly in urban areas of eastern Iowa and nearby regions.
