First Alert Day with scorching heat today; slightly cooler days are ahead

ROCHESTER, Minn. (KTTC) – We’re starting the week today with a big dose of steamy sunshine across the region. Temperatures are warming through the 90s today as an air mass of tropical origin worked its way northward into the Upper Midwest ahead of a cold front that is approaching from the west. Expect a bright and sunny sky with high temperatures in the mid-90s and heat indices in the low 100s. A gusty south breeze, meanwhile, is doing what it can to stir the air for us. Expect those winds to reach 25 miles per hour at times. A Heat Advisory will be in effect for most of the area until 9:00 this evening and because of that, this is a KTTC First Alert Day.
