- Milder and wetter conditions are expected for late week.

DISCUSSION

Issued at 119 PM CST Sun Jan 18 2026

Today Through Tuesday Night: A broad polar trough anchored over eastern CONUS will keep our CWA locked into a cold and dry pattern through Tuesday night. Surface high pressure will reinforce below average temperatures with little in the way of cloud cover or precip chances. Winds will remain northerly to northwesterly adding a wind chill at times, however wind chill values are expected to stay just below advisory thresholds.

Wednesday through next Weekend: Midweek will bring a shift in the pattern as polar flow lifts north, allowing warm air to advect into the region. This transition will bring rain chances back to the forecast along with a noticeable warming trend from Wednesday into Friday night. Current guidance suggest rainfall totals will be decent with minimal instability, limiting the potential for thunderstorms. By the weekend, model consensus decreases as models vary on timing of a strong 1045 mb polar high surging southward from Canada through the Midwest. When the polar air does make its way to our area zonal flow will help set up a distinct baroclinic boundary across the area, helping to maintain a active weather pattern. Forecast refinements are likely as confidence increases as we progress through the week./KP/
