Heavy rainfall from scattered thunderstorms is expected across the Southwest, Intermountain West, and Plains. Isolated dry thunderstorms may initiate additional fires across the west. The coastal Carolinas may experience flash floods in the coming days due to repeated thunderstorms. Additionally, a wave of intense summer heat will hit the Southern Plains and central Gulf Coast States this week. Read More >
Overview
|
A strong area of low pressure lifted northeast across the Great Lakes, bringing a swath of heavy snow to eastern Wisconsin on Saturday, March 25, 2023. Initially, the surface low was forecast to track northeast across southern Illinois and central Indiana, with a west to east area of banded snowfall. However, as the event unfolded, the surface low tracked further northwest across northeast Illinois and northwest Indiana. This allowed the banded area of heavy snow to shift to the west, by about 30-60 miles, and become oriented more south to north, centered over the Fox Valley. The snow piled up quickly (2-4" per hour!) due to impressive snowfall rates on Saturday morning, leading to difficult travel, and a few isolated power outages. Both Green Bay and Appleton saw record snowfall during this event. Please see the tabs below for more information. |

Snow Reports
 |
Due to the nature of this type of banded snowfall (frontogenetic) and how quickly the snow fell, snow reports varied significantly within the swath of snow, and even from one side of a town to another. Other factors, such as when the observation was taken, drifting, and compaction, also contributed to the large variations in measurements.
