KEY MESSAGES

- Light to occasionally moderate snow today, especially across the eastern half of the area. 1-2, locally up to 3 inches of accumulation is expected.

- Snow showers continue this afternoon and into this evening. Gusty winds along with the snow will result in decreased visibility at times.

- Mild to start the workweek.

SHORT TERM

Issued 212 AM CST Sat Jan 10 2026

Today through Sunday:

Light to occasionally moderate snow will overspread the region this morning. This morning's snow is associated with a shortwave moving northeast from the lower Missouri Valley. Precipitation will be mainly focused east of I-39/90, with the highest accumulations along the Kettle Moraine. Surface temperatures are somewhat marginal near the lakeshore, with mid to upper 30s noted, and a brief period of rain/snow mix is possible in this area before temperatures cool a few degrees. Overall look for 1-2 inches of snow east of I-39/90 through noon, locally up to 3 along the Kettle Moraine.

A break in the precipitation is expected mid day as the initial wave moves east of the area (some clearing is possible as well). Moisture associated with a second, stronger northern stream shortwave will then push into the area mid afternoon, and this should bring scattered snow showers back into the region. These don't look to be true snow squalls, but gusty northwest winds will contribute to reduced visibility with this activity. Snow showers may then linger into tonight across the far eastern portion of the forecast area, as another lobe of vorticity sweeps across the region.

Highs today will be in the low to mid 30s, with falling temperatures this afternoon as cold advection increases. Lows tonight will fall into the upper teens to low 20s.

Sunday will be a fairly pleasant day, with highs around 30 and partly cloudy skies.

LONG TERM

Issued 212 AM CST Sat Jan 10 2026

Sunday night through Friday:

Temperatures will be a bit of a roller coaster this week as a series of shortwaves move through the Great Lakes. Warmer temperatures are expected to begin the workweek, with highs Monday and Tuesday in the 40s. A clipper and associated cold front will move through the region on Tuesday. There will initially be a chance (30-40%) for rain on Tuesday, followed by chances for snow Tuesday night and Wednesday as colder air builds into the region. Temperatures briefly warm once again for Thursday, before another cold front is expected for Friday into the weekend.

AVIATION

Issued 212 AM CST Sat Jan 10 2026

MVFR ceilings will continue across the region this morning. Light snow will then overspread the terminals before daybreak, continuing into mid day. IFR ceilings and visibility are likely with this activity. A brief break in the snow is expected early afternoon, with a potential improvement to VFR. Another round of snow showers is then expected to move through the area this afternoon into this evening, with MVFR and IFR conditions once again.

Winds will initially be light and variable this morning, becoming more westerly and then northwesterly through the day. Gusts will pick up considerably this afternoon and evening, continuing into Sunday morning.

MARINE

Issued 212 AM CST Sat Jan 10 2026

Weak low pressure around 30.0 inches over northern Minnesota will dig southward and weak low pressure around 30.0 inches over southern Missouri will lift northeastward early this morning. These systems will merge over the Great Lakes today, and this area of low pressure will deepen to 29.5 inches as it lifts into eastern Ontario tonight. Expect west-northwest winds to increase this afternoon into tonight as high pressure around 30.6 inches builds across the central Plains. Northwest gales are expected, and a Gale Warning is now in effect for tonight through Sunday morning. Winds gradually ease Sunday evening into Monday as high pressure moves into the Ohio Valley. Southerly flow will return by Tuesday ahead of another low pressure system, which is progged to traverse north of Lake Michigan through the middle of next week.
