News 19 Forecast Team Blog: Heavy rain pounds the Midwest

A low pressure system over the Midwest has produced a wet end to the work week. Perhaps some of the most noticeable affects have been felt through parts of northeastern Iowa. Over the past 24 hours Clayton County has witnessed over four inches of rain. Grant County in southwest Wisconsin has also been a victim of high rainfall amounts. Emergency management officials have reported damage and mudslides over the central portions of the county. The chance for showers and thunderstorms will continue today and counties in the News 19 viewing area could see anywhere from 0.5"-1.5" of rain. The heaviest rainfall will likely fall during the morning. Crawford County is under a Flood Warning due to the levels of the Mississippi River, and will remain under a Flood Warning until the river falls back below the flood stage.
This week is Severe Weather Awareness week and there are a few things to keep in mind during flooding situations. Most importantly if you see a flooded area, TURN AROUND, DON"T DROWN. This becomes extremely important if you encounter flooding while you are in your vehicle. Many people believe that their 3,00 pound or more vehicle will remain in contact with the road in flooding situations but the force of buoyancy can float your vehicle away. In fact, most cars can be swept away in 18-24 inches of moving water. For anyone attempting to walk or wade through flowing water, as little as 6 inches of flowing water can sweep you off your feet.
A cold front will sweep through the Tri-State this afternoon and with it will be the slight risk for severe weather across the south and eastern portions of the viewing area. Gusty winds, hail and isolated tornadoes are all possible. Fortunately it is a cloudy and rainy start to the day, so the instability in the atmosphere won't be as high as it would be if it were sunny. Instability is one of the key ingredients to severe weather. Perhaps the biggest punch from the cold front will be much cooler air. This weekend afternoon highs will hover around a cool 50 degrees.
