Bitterly Cold Temperatures Continue for Southern Wisconsin

• A Cold Weather Advisory is in effect until noon today
• Additional periods of 10 to 20 below zero wind chills likely
• An overall dry weather pattern in the week ahead

MADISON, Wis. (WMTV) – A broad area of high pressure over the Upper Mississippi Valley has produced mostly clear skies, light northwest winds, and dangerously cold conditions across southern Wisconsin this morning. Overnight radiational cooling has dropped temperatures into the teens below zero, and wind chills are ranging from -20 to -30.

A Cold Weather Advisory is in effect until noon today for much of southern Wisconsin. Conditions will slowly improve late this morning, but cold and dry weather will persist through the day.

What’s Coming Up…

Late tonight and into Sunday morning, there is a chance that a lake-effect band of snow could move west toward southeastern Wisconsin. If it reaches shore, it may bring accumulating snow and higher snowfall rates, mainly from Milwaukee southward, though confidence remains low. A separate system passing to the south could also produce light snow or flurries south of I-94 and US-18 on Sunday, but little to no accumulation is expected. Otherwise, Sunday will remain dry and cold, with wind chills between -10 and -20 Sunday night and a growing chance for wind chills below -20 by early Monday morning. Additional cold weather headlines may be needed.

Looking Ahead…

Looking ahead, things will remain quiet and largely uneventful as an upper-level trough dominates the eastern CONUS and high pressure systems move through the Plains and Great Lakes. This pattern favors weak surface flow, continued cold and dry air, and limited lift aloft, making precipitation difficult to produce. A weak cold front will pass through on Tuesday, bringing the chance for a few flurries.

Temperatures will gradually moderate through the week, with highs in the single digits Monday rising into the teens by midweek, and indications of highs reaching the 20s beyond the seven-day forecast.
