The Milwaukee Marathon weekend is set for April 11-12, featuring a marathon and half-marathon on Saturday and a 5K on Sunday. According to Aidan Kuroski, a meteorologist with the National Weather Service in Milwaukee/Sullivan, Saturday will likely remain dry for most of the day, although rain may arrive in the late afternoon. Overnight rain could impact the Sunday 5K, making conditions wetter for participants. However, there is a chance that the rain will ease up by Sunday morning, with temperatures expected to reach the mid-70s if the sun shines. By Monday, temperatures could reach the mid-to-upper 70s. Kuroski also warned of potential severe weather next week, advising residents to monitor the situation for flooding risks, especially if heavy rain occurs. Overall, while the weekend may start with some rain, warmer temperatures are anticipated.
