Milwaukee starts Sunday near 64 degrees with calm winds and mostly clear skies, but the quiet opening will not last. Showers and thunderstorms are expected to build late this morning and continue into the afternoon, with heavy rain and potentially dangerous storms in the forecast.
Storms Arrive By Late Morning
A slight chance of showers and thunderstorms begins around 10 a.m., with the best chance for storms from roughly 11 a.m. through 2 p.m. Sunday’s high should reach about 77 degrees, with southerly winds around 5 to 10 mph and rainfall totals generally between a quarter-inch and a half-inch, according to the National Weather Service Milwaukee/Sullivan office.
Some storms could be strong to severe, with damaging wind gusts the primary concern. Small hail and a brief tornado cannot be ruled out, while storms that repeatedly move over the same areas could produce localized flooding.
Evening Storm Round Remains Uncertain
Another chance of showers and thunderstorms returns Sunday evening and continues into the night, when temperatures fall only to around 67 degrees. The exact location of that round remains uncertain, but heavy rain would again be possible if storms develop near or south of Interstate 94.
No watches, warnings or advisories are currently listed for Milwaukee County, though conditions could change as storms approach. People heading out Sunday should keep a way to receive weather alerts and avoid flooded roads, especially during the late-morning and afternoon storm window.
More Storm Chances Before A Cooler Turn
Monday looks warmer and somewhat quieter, with a high near 79 degrees and only a slight chance of storms after 4 p.m. Another unsettled day arrives Tuesday, when temperatures may reach 80 and rain showers and thunderstorms could bring three-quarters of an inch to an inch of rain.
The pattern trends cooler and drier later in the week. Thursday’s high is expected to reach about 73 degrees, followed by a mostly sunny Friday near 71, although a few showers remain possible Friday morning.
