Heat, humidity bring thunderstorm potential overnight into Tuesday, June 14
Thunderstorms are possible Monday, Tuesday and Wednesday.
BRAINERD — The lakes area is in for a hot and humid week, with the possibility of some severe thunderstorms.
The week’s first storms were expected in the early hours of Monday morning, June 13, as a complex of thunderstorms developed across the Dakotas and moved into Minnesota, said Bryan Howell, meteorologist with the National Weather Service in Duluth.
The thunderstorms were poised to hit Brainerd around sunrise Monday, Howell said, potentially bringing wind gusts over 60 mph and large hail. There could be some isolated showers and thunderstorms later throughout the day.
A chance of more storms exists Tuesday but could be thwarted by heat, as temperatures are projected to reach 91 degrees, accompanied by high humidity.
“We’re going to have plenty of fuel around for thunderstorms,” Howell said. “It’s just because it’s going to be so warm, temperatures aloft are going to be warm enough so that storms can’t develop. So we really don’t know. If it’s too warm, or if something — some sort of trigger mechanism — comes and gives us the lift for thunderstorms, then it could break through that cap and then we could have some potentially severe storms. But it’s looking like it’s going to be too warm for that to happen right now.”
But a cold front expected to come through in the late afternoon or early evening could provide the lift Howell said is needed for thunderstorms.
“Storms are kind of like a machine,” he said. “Once they get going, they just kind of keep going, using all that energy that’s up in the atmosphere, but it has to get to a certain point high enough in the atmosphere for that to just start sustaining itself.”
Thunderstorms aside, heat exhaustion is another danger Howell said lakes area residents should be cognizant of and take precautions against as temperatures and humidity both rise.
“Stay hydrated, take it easy, find some shade if you’re out working,” he said. “Heat exhaustion and heat stroke can creep up pretty fast, especially when it’s hot and humid.”
Wednesday afternoon and evening also brings another chance for thunderstorms, as temperatures drop back to the high 70s.
