Friday will be very warm across southern and western Minnesota. There will be isolated thunder chances. More organized rainfall develops Sunday night.

Summer temps Friday, Saturday; isolated weekend rain chances

There are a few spotty showers and thunderstorms early Friday as warmer air surges into the state. There’s the possibility of a couple more developing later in the day, too.

The National Oceanic and Atmospheric Administration’s High-Resolution Rapid Refresh forecast model is the most aggressive:

The morning activity is developing ahead of the blast of warmer and more moist air aloft. Winds at about 4,000 feet up are pushing warmer air in on a low-level jet stream. This is creating elevated thunderstorm activity.
