After a cool start to the day with lingering fog and low clouds, southern Wisconsin is in for a warm-up heading into the weekend. Temperatures are expected to climb into the 60s on Saturday, the best spring-like day of the forecast, before a weak system brings a chance of light rain and cooler conditions on Sunday.

Why it matters

The changing weather patterns in Milwaukee are typical for this time of year as the region transitions from winter to spring. The warm-up will be welcomed by residents after a chilly start to the week, allowing them to enjoy more mild and pleasant conditions over the weekend.

The details

Friday morning will see some lingering patchy fog and low clouds, but overall the weather setup across southern Wisconsin is quiet. Temperatures will be a bit tricky depending on the cloud cover, but the real highlight is the warm-up that builds in for Saturday. Saturday is expected to be the best spring day of the forecast with highs pushing well into the 60s. A weak system will then slide through Saturday night into Sunday, bringing a chance of light rain and a noticeable cooldown. After that, the weather is expected to settle into a quieter stretch early next week before the next chance of rain arrives by Thursday.

  • Saturday: Highs pushing well into the 60s
  • Saturday night into Sunday: Chance of light rain and cooler temperatures
