SIOUX FALLS, SOUTH DAKOTA — Two separate Level 2 severe weather risk areas are in place Sunday to cap off the weekend, one covering the Dakotas and northwestern Minnesota and the other targeting much of northern Iowa. The upper Midwest will see the earlier storm threat develop along a warm front during the mid-day and early afternoon hours, initially posing a threat of large hail and damaging winds across the northern Iowa zone.
Tonight, the threat shifts west into the Dakotas and western Minnesota where elevated storms will pose the threat of damaging winds and very large hail potentially exceeding two inches in diameter. In a notable development, the Storm Prediction Center has issued no tornado areas anywhere in the country today.
Northern Iowa Faces Midday Warm Front Storm Threat
The earlier severe weather focus Sunday centers on northern Iowa, where storms firing along a warm front during the mid-day and early afternoon will bring the potential for large hail and damaging winds to the region. This Level 2 risk area covers a corridor from Sioux Falls through Des Moines and toward the Chicago area under a broader marginal risk zone.
Dakotas and Western Minnesota See Hail Over Two Inches Tonight
As the day progresses, the severe threat shifts westward into the Dakotas and western Minnesota, where elevated thunderstorms tonight will carry the potential for very large hail exceeding two inches in diameter alongside damaging winds. This overnight threat across the Rapid City and Billings corridor deserves close monitoring heading into Sunday evening.
Scattered Damaging Wind Threat Extends to Carolinas and Texas Panhandle
Beyond the primary Level 2 risk zones, scattered afternoon thunderstorms firing across the Carolinas and the Texas Panhandle could also produce damaging winds Sunday. These threats fall within the broader marginal and general thunder risk areas shown on the categorical outlook map.
