...NWS Damage Survey for 04/28/25 Eau Claire County Tornadoes...

.Overview...A surface low pressure tracked from the Dakotas through
central Minnesota on the afternoon of April 28. Thunderstorms
developed along a dryline boundary in the early afternoon across
western Minnesota and eastern South Dakota. Several severe
thunderstorms formed along the dryline and moved eastward through
southern Minnesota into western Wisconsin in the afternoon and
early evening hours of April 28. A significant severe weather
setup was in place across the Upper Mississippi River valley with
moderate surface instability and strong shear present along and
ahead of the dryline. Initial supercells congealed into a line of
severe thunderstorms as they tracked near Eau Claire County after
7 PM. This line would produce several tornadoes and numerous
reports of large hail across southern Minnesota and western
Wisconsin through the evening hours.
