A midweek warm-up arrives in Green Bay and Northeast Wisconsin before a late-week system brings a wintry mix and renewed rain and snow chances.
3 THINGS TO KNOW
- Temperatures rebound into the 40s and 50s by midweek, accelerating snowmelt
- A wintry mix is likely Wednesday night into Thursday with rain, snow, and possible freezing rain
- Rising rivers will be a key concern as snowmelt continues across northeast Wisconsin
A Spring Tug-of-War Ahead for Green Bay and Northeast Wisconsin
The week ahead across Green Bay and northeast Wisconsin is shaping up to be a classic early spring pattern, with fluctuating temperatures, periods of quiet weather, and a midweek system that could bring a messy mix of precipitation.
After a brief cooldown to start the week, temperatures rebound quickly, setting the stage for melting snow, rising rivers, and a late-week system that may bring rain, snow, and even some freezing rain.
Early Week: Quiet but Cool Start
A cold front moving through Sunday ushers in a cooler air mass, knocking temperatures back closer to seasonal levels. Highs will settle into the 30s and 40s with a brisk north wind early, before conditions calm later in the day.
High pressure builds in Sunday night and Monday, bringing mainly dry weather and lighter winds. This will be one of the quieter stretches of the week, offering a brief break from active weather.
Midweek: Warmer Air Returns
By Tuesday, the pattern shifts again as warmer air surges back into the region. Highs climb into the 40s and lower 50s from Tuesday through Thursday, running above normal for late March.
This warming trend will accelerate snowmelt across northeast Wisconsin. Rivers and streams will continue to rise, with some expected to reach bankfull or minor flood stage over the next several days.
While much of Tuesday may stay dry, small chances for precipitation begin to creep in, especially across northern parts of the region late Monday night into Wednesday.
Late Week: A Messy Mix Moves In
The most active stretch of the forecast arrives Wednesday night into Thursday as a clipper system and cold front sweep through the Great Lakes.
This system is expected to bring the most widespread precipitation of the week, and it may not fall as just rain. A mix of rain and snow is likely, with the potential for some freezing rain mixed in, especially during the transition periods.
With temperatures hovering in the 40s and lower 50s, precipitation type will depend heavily on timing and local conditions, making this a system to watch for potential travel impacts.
End of the Week: Calmer Conditions Return
By Friday and Saturday, high pressure regains control, bringing drier conditions and a return to more seasonable temperatures.
While the pattern remains active overall, the end of the week looks quieter compared to the midweek system.
The Bigger Story: Snowmelt and Rising Rivers
Beyond the day-to-day forecast, the larger concern this week will be hydrology.
Even without heavy rainfall, ongoing snowmelt is expected to drive rising river levels across northeast Wisconsin. Forecasters note that while widespread rapid flooding is not expected, several rivers could reach bankfull or minor flood stage.
This will be a slow-moving situation that will need close monitoring through the week. Check our Forecast Page for updates in your area.
