Storms overnight, then dangerous weekend heat – Chris

A round of thunderstorms is expected to move through Minnesota late tonight and into early Friday morning, potentially impacting the morning commute with downpours and lightning. A few storms could be strong, so give yourself extra time if you’re heading out early.

After the morning storms, Friday turns partly cloudy, very warm, and muggy, the prelude to a much more intense stretch of hot weather.

Both Saturday and Sunday are Forecast First Alert days. Excessive Heat Warnings are in effect from noon Saturday to 9pm Sunday, when heat index values could soar to 105 to 110 degrees. Highs in the Twin Cities will push the upper 90s, with records in jeopardy. This will be the most dangerous heat of the season so far.

Heat remains the number one cause of weather-related deaths, especially when it catches people off guard. Make sure you’re hydrating, limiting time outside, and checking on loved ones—especially the elderly, children, and pets.

One place that will escape the worst of the weekend heat is Duluth. This is good news for Grandma’s Marathon. Runners will start with temps in the 60s, though a chance of thunderstorms lingering from Friday night will need to be monitored closely.

Storm chances return to our area Sunday night into early next week as a cooler pattern moves in. But until then, prepare now for extreme heat and stay weather-aware tonight.
