Severe Thunderstorms in the Central U.S.; Upper Level Low Over California

Scattered severe thunderstorms are possible today across central and eastern Minnesota, Iowa, and western Wisconsin. A few tornadoes, isolated very large hail, and damaging winds may occur. An upper level low will help trigger scattered thunderstorms over portions of central and southern California today along with a few inches of snow in the central Sierra Nevadas. Read More >

Overview

A strong area of low pressure listed northeast across the region, bringing a swath of heavy snow to southern Wisconsin late Friday, March 24th into Saturday, March 25th, 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 allows the banded area of heavy snow to shift to the west and become oriented more south to north. 

The snow stacked up quickly due to impressive snowfall rates on Saturday morning, leading to difficult travel and a few isolated power outages. Both Madison and Milwaukee saw record snowfall during this event. Head over to the Snow Records and Reports tab to see these records!
