DISCUSSION

Issued at 151 AM CST Sun Jan 25 2026

Tonight and Monday Morning

The surface pressure gradient will gradually tighten tonight as a 1039 mb surface high moves southward into the Central Plains and a 997 mb surface low moves over the Gulf Stream east of Massachusetts. This will increase the west winds into the 5 to 15 mph range. With temperatures primarily in the 10 to 20 below range, wind chill values will range from 25 to 35 below. Due to this, a Cold Weather Advisory has been issued from midnight tonight through noon Monday. This looks to be the only one of those this week.

Monday Night

A Canadian cold front in the northwest flow aloft will move southeast through the region on Monday night. Soundings show that the low levels will saturate up to 750 mb north of Wisconsin 29. The models are in fairly good agreement that there will be 2 to 3 hundreths of an inch of QPF. With snow to liquid ratios around 20 to 1, we are looking at up to a half- inch of snow.

Remainder of the week

The area will remain in northwest flow through the remainder of week. This will result in high temperatures ranging from the single digits to the teens through Friday and then temperatures warm into the weekend. High temperatures on Saturday will range from the mid-teens to lower 20s on Saturday and into the lower and mid-20s on Sunday. Low temperatures will be in the single digits below and above zero through next weekend. With the exception of next weekend, much of this time period looks dry.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1140 AM CST Sun Jan 25 2026

Predominately VFR conditions are forecast for the TAF period with current MVFR stratus over south-central and southwest WI slowing its westward progression and moving back east later today. There is a 10-20 percent chance for a period of MVFR ceilings this evening areawide, but confidence in this occurring is decreasing given the lack of clouds upstream. Winds will be from the NW at 5-10 kts this afternoon and evening, backing to the WSW for Monday morning.
