Areas like Missouri, southern Iowa, and southern Illinois show a below-normal risk, while regions prone to persistent lake-effect snow, such as the Upper Peninsula of Michigan and northern Wisconsin, have an above-normal risk. While there is a 50 percent or greater chance for minor flooding at several forecast points, no points currently indicate a 50 percent or greater chance for major flooding. These outlook conditions are heavily influenced by the preceding fall and early winter environment. The Midwest experienced its sixth- warmest autumn on record, characterized by significant dryness with precipitation levels below 75 percent of the typical average. This led to dry soil moisture conditions across most of the region before the winter freeze-up, which currently helps mitigate flood risks by providing more capacity for the ground to absorb future meltwater. Winter conditions transitioned to below-average temperatures with several Arctic air outbreaks that facilitated frost development. Frost depths are currently near normal across the north, but frost has begun to thaw in some locations. Snowfall has been variable; while much of the region has below-normal snow water equivalent (SWE), significant lake-effect events have resulted in high SWE totals of 7 to 10 plus inches in parts of Michigan's Upper Peninsula. Upcoming precipitation events, particularly this weekend, will have an impact on the overall flood outlook as significant precipitation is expected especially from Wisconsin and across Michigan and could lead to or exacerbate ongoing high water concerns in those areas. Looking ahead, the climate outlook is influenced by ongoing La Nina conditions, though its signals are not currently strong. There are equal chances for above or below-normal temperatures through the spring, while above-normal precipitation is favored specifically across the Great Lakes region. As the season progresses, La Nina is expected to wane, transitioning toward an ENSO-neutral state by late spring. && NCRFC
