Heat Tuesday, heavy rain Thursday for southern MN
Most of the thunderstorms in the country today have been breaking out across the eastern half of the country.
In Minnesota, some have popped over the arrowhead region and have been tracking southeast into northern Wisconsin and Upper Michigan. A few recent thunderstorms have broken out in far northwestern Minnesota.
The west is getting fewer storms than on a usual summer afternoon, but New Mexico is lighting up nicely.
While there have been some towering cumulus clouds trying to become showers or small thunderstorms, the sky also has had a distinctly hazy appearance. The culprit seems to be Canadian wildfires.

By Thursday, moisture, instability and lift will surge north of the stalled frontal boundary to trigger widespread heavy rain over much of the southern half of Minnesota and then into Wisconsin on Thursday and Thursday night.
Amounts of rainfall are difficult to forecast, but this type of weather system is likely to produce lengthy periods of rain, some of it heavy. Some rainfalls in excess of 2 inches are likely.
