Forecast First warning: Heat and severe storms possible this weekend

Here is your Friday night forecast for July 12, 2024 from the Minnesota Weather Service and meteorologist Matt Serwe.

Saturday and Sunday are the first warning days in Minnesota and northwest Wisconsin. A heat warning is in effect for western Minnesota and the Twin Cities, and severe storms are possible.

There are two things to watch out for this weekend: It will be hot and humid, and severe storms are possible. First, let’s talk about the heat. Although we’re already approaching heat, Saturday and Sunday will likely be the first 90° days of the season in the Twin Cities. Humidity will also rise, making it feel significantly more uncomfortable. On Saturday, parts of western Minnesota will feel like 100° to 105°. Both Saturday and Sunday could feel like 95° to 100° in the Twin Cities.

As the season gets hot and humid for the first time, here are a few tips. Most importantly, listen to your body. If you feel too hot, find a shady spot or air-conditioned accommodation. Be sure to check on the young and old in your family and community. Heat can quickly affect children and the elderly. Most importantly, remember to stay hydrated and drink plenty of water when you are outdoors.

Storm chances are still a bit uncertain this weekend. Storms will likely develop closer to the Red River Valley and move southeast Friday night, Saturday night, and possibly again Sunday night. How long these storms last into the next day will determine when and where they develop again in the evening. Any overnight storms could bring strong winds and hail, but if they develop a little earlier, there is a slight chance of tornadoes.

Monday will be another hot and humid day, with more thunderstorms possible in the afternoon and evening. Once we get past that, we’ll have a calm and pleasant period of weather next week. Expect highs in the 80s and a few dry days.
