Warm sunshine today; heat, humidity, and increasing thunderstorm chances this weekend

ROCHESTER, Minn. (KTTC) – Warm, humid weather is going to once again take center stage in our weather picture as we approach the weekend. After an amazing day of mild sunshine and September-like conditions, we’re going to enjoy plenty of sunshine throughout our Friday with a south breeze that will work to pull in some warmer, more humid air. High temperatures will be in the mid-80s this afternoon with heat indices around 90. Temperatures will slowly fall back into the 70s overnight tonight with a few passing clouds and a slight south breeze.
