The January 12-13, 2024 Winter Storm
|
Event Overview A strong low pressure system storm moved from the southern Plains northeast into the central Great Lakes, bringing near-blizzard conditions to the southeast half of Wisconsin from January 12 to early January 13, 2024. The low pressure system strengthened rapidly as it approached southern lower Michigan by early evening January 12. By 6 am Saturday January 13, the storm dumped a swath of heavy wet snow that was accompanied by very strong northeast winds that created 2-3 foot snow drifts. The highest snow totals (~18 inches), were associated with a relatively narrow lake-enhanced snow band that meandered over far northern Brown, southern Oconto and Door counties. The snow band produced snowfall rates up to 2 inches per hour and near whiteout conditions at times. The intense surface low pressure developed in associated with strong upper-level jet stream energy that dove southward into Texas a few days earlier, then raced northeast toward the Great Lakes Region. Roads quickly became snow covered, making for hazardous travel conditions. Some school activities and businesses were closed Friday into Saturday. Winds of 35 to 55 mph caused sporadic power outages with over 100,000 customers losing power during the storm. On Lake Michigan, winds gusted to around 40-45 kts and created waves of 10 to 18 feet.
