Today: The 5-Day Weather Forecast March 12, 2026, starts with clear skies at cool temperatures. Southwestern winds of 12 mph send Milwaukee in the mid-40s for a high. While the evening commute finishes, winds pick up with the arrival of a strong low-pressure system. Along with this, precipitation chances spike as the sunsets.
Tonight: Rain greets the night as winds howl out of the south. Gusts could reach 50 mph according to the NWS Wind Advisory issued for overnight Thursday into the day Friday. Expect steady winds of 25 mph. Coupled with the precipitation possibly turning to snow later, this creates hazardous travel conditions until Friday midday. As this happens, temperatures decrease to 34.
Tomorrow: Rain totals reach a tenth-inch in the early morning, and snow totals should not exceed two-tenths of an inch. Due to the northwestern winds, temperatures continue to drop throughout Friday. Clouds break and winds calm in the afternoon, but not soon enough to combat the cold weather. Temperatures eventually hit a low of 24. A high pressure leaves during the night, importantly shifting winds.
Extended: Saturday into Monday sees the development, arrival, and exit of a potent low-pressure system. Sending some light flurries Saturday morning, snowfall rates dramatically increase in the evening. Temperatures rise to 34 as winds from the east blow through the metro. Attached to the front of this system, wind gusts exceed 40 mph. These winds cause Milwaukee’s snow to turn into rain over Sunday until the evening. As the rain transitions back into snow, winds could easily hit 50 mph. If the rain transitions back to snow fast with sufficient precipitation behind, travel could become extremely hazardous. With current data, by Monday Milwaukee receives 6 inches of snow, tenth-inch of freezing rain, and over a quarter-inch of rain.
To be clear, many sources have circulated information about snow exceeding this. While possible, it is preferred to defer totaling precipitation to the following forecasts. It is crucial to stay informed about this winter storm, so stay tuned to your local forecast!
