Today: The 5-day Weather Forecast December 14, 2025 begins with an expiring Cold Weather Advisory from the National Weather Service (NWS). As Milwaukee emerges from the negative temperatures, a few clouds linger over head driven by the dying winds. Although winds gust through at 25 mph in the morning, this lessens as the prevailing high-pressure exits to the southeast. Without the intense high pressure influencing the area, precipitation chances begin to increase. Temperatures rise to 7 before sinking back down with the onset of night around 4:15 p.m.

Tonight: Due to the passing of a weak low pressure to the north, clouds return as some snowflakes whiz about late in the night. Temperatures hit 1 before the southern winds start warming the area. This system sets the stage for an active week of weather by pulling winds up from the south. With warmer temperatures in the atmosphere, it becomes important to view the critical thickness benchmarks. These lines aid in predicting whether precipitation will be frozen, mixed, rain, or other. Tonight, the critical thickness for tonight into tomorrow trends to cut through Milwaukee on most models, so any snow might accompany some freezing rain. While totals of snow and ice should stay nearly unnoticeable, still take care with travel and outdoor activities.

Tomorrow: A snowflake and a drop of freezing rain might be found today before clouds part for the sunset. Temperatures spike to 21 as southern winds gusting at 31mph take to the streets of Milwaukee. After sunset, Monday allows a relatively calm night, as temperatures ease to 15 and winds slow.

Tuesday: In the morning of the 16th, winds pick up to a constant 13 mph, shoving southern air into the Midwest. Resulting from this, temperatures jump higher once again, past the freezing point, to 34. A potent low-pressure system makes its way across the northern banks of Lake Superior later on Tuesday, causing a small bit of precipitation in Milwaukee. With it, the critical thickness lines retreat to the north. The ice crystals of clouds then melt further from the earth when falling and reach the surface as rain. Totals amount to very little. Although temperatures reach 27 ending the night, Wednesday sees temperatures launch back into the 30s, so if anything freezes, it would not be for long.

Extended: Quieting with lower gusts and sustaining 10 mph, winds spin from northwest to southwest in anticipation of the next system. Late Wednesday night, temperatures spike further into the high 30s, and by the morning of Thursday, Milwaukee breaks past 40. Winds from the south blast through at 15 mph, with gusts easily touching 40 mph. Pressures drop quickly as the Alberta Clipper charges Milwaukee. High winds pause while rain steadily falls until the cold front and critical thickness lines catch up to our warmth. When rain tapers off, freezing rain and snow quickly follow. Attached to the end of this Clipper, winds resume in full force, propelling polar air back into the Midwest. Snow showers will also frequent the area with an accumulation of around a quarter inch. Stay up to date with your forecasts to get the latest on this mid-week storm. As always, stay safe.
