Alaska Storm to Bring Significant Coastal Impacts; Threat of Flash Flooding Continues in the Southwest

A powerful Chukchi Sea, Alaska storm will produce high winds and coastal flooding that could impact critical infrastructures across western and northwestern Alaska. Locally heavy showers and thunderstorms in the Southwest may produce flash flooding, especially on burn scars, slick rocks, and dry washes. A cold front will bring fall temps and a wintry mix to the Upper Midwest and Great Lakes. Read More >

After temperatures warm up to 5 to 10 degrees above normal today, a cold front is forecast to move through the area tonight. Behind the front, look for highs in the 50s and 60s Friday and Saturday. However, the cool down looks short lived as near to just above normal temperatures are favored by Sunday and Monday.
Much colder air is on its way, and by Saturday morning freezing temperatures are possible across the region. Areas of northeast MO and west central IL will have the greatest potential for a freeze, where a Freeze Watch has been issued. Elsewhere, frost is possible across the entire region. Sensitive outdoor plants should be protected.
River levels along the Mississippi and Missouri Rivers are lower than normal for this time of year. They are particularly low on the Missouri River due to widespread drought conditions upstream. More than 70% of the Missouri River Basin is in moderate drought or worse, leading to very low flows downstream. The Missouri River at Herman is lower than 95% of the previously recorded river observations at this time of year.
