Low pressure will continue to push eastward across Missouri today and into the lower Great Lakes region by Thursday night. Thunderstorms will continue intermittently through tonight, especially across the east. Moderate to heavy rainfall is possible with thunderstorms and may lead to localized areas of ponding water and rises on local streams and rivers. A flash flood watch is in effect for eastern Iowa. Colder air will push south into the region throughout the day today, with rain gradually changing to snow. A wintry mix is likely across the northwest, with freezing rain also possible across the north overnight. Accumulating snow will be restricted to the north and west. Higher snowfall totals are possible north of Iowa, with light snow lingering into Thursday.
