Overview: Milwaukee’s 5-Day Weather Forecast May 13, 2026, finds warmer weather with increasing rain chances into the weekend.
Today: We start at 48 degrees on Wednesday morning with a small bit of fog and warm to 60 by noon. As northern 30-mph gusts in the morning taper down to 17 mph, the wind turns to come from the east thanks to a high pressure moving over Lake Michigan. Partly cloudy skies rule the rest of the day but disperse in the night.
Tonight: Without clouds and relatively calm wind, the night gets down to 41. The high-pressure system then parks over the northern Midwest.
Tomorrow: Thursday harbors clear skies and a high of 62. Calm winds increase to 10 mph over the day, but gusts remain below 20 mph. Clouds begin filling in for a picturesque sunset at 8:07 p.m. as the high-pressure system moves out east. With winds strengthening from the south in the second half of the day, Milwaukee’s low rises from the previous night to 44. However, Thursday night sees some occasional drizzles grow into rain showers, persisting into Friday.
Friday: Rain clouds break from mid-morning to early afternoon, allowing temperatures to enter the 70s. Due to a low-pressure system passing to our north, wind gusts increase to 35 mph, with steady winds averaging 12 mph. Around 3 p.m., rain begins anew, intensifying to possible thunderstorms by the early night. This proves inconsistent though, so local rain gauges might see up to a half inch of rain over Friday. The low temperature sinks into the 50s.
Weekend Outlook: Omitting Friday night’s rain overlapping Saturday morning, Saturday stays dry with partly cloudy skies and a high of 77. Despite the low pressures surrounding Wisconsin, Milwaukee finds solace in a weak high-pressure area, decreasing winds. After a low of 52, winds increase and average 12 mph with gusts near 25 mph on Sunday. Two rounds of showers seem to come through Milwaukee in the morning and in the evening. Temperatures vary from the 70s to 50s, so stay tuned for your updated weekend forecast!
