Hope you enjoyed the bright, breezy, unseasonably cool Mother’s Day. Forecast focus quickly shifts to the possibility of frost developing overnight. The modest heating Sunday quickly radiates after dark as scattered clouds clear and the stiff breeze fades. Any sensitive plants or flowers should either be brought in or covered-up tonight to protect from frost.
A blanket of unseasonably cold air covers a good chunk of the eastern U.S., with Frost Advisories and/or Freeze Warnings from the Lower Michigan to the Tennessee Valley.
Locally temperatures will near record levels tonight. The chilly temps will only last a few hours, as a bright sky quickly pushes temperatures into the 60s Monday afternoon.
You’ll need a jacket early if you’re heading to IMS for practice, but the afternoon will be much more pleasant with a lighter breeze and warmer temps.
Though warmer, highs Monday will remain a good 10° cooler than normal. That changes big time Tuesday behind the passage of a warm front. Highs return to the 80s from Indianapolis and points west…and the entire area will be well into the 80s Wednesday.
Very late Wednesday (more likely after dark) is our next rain chance as a frontal system stalls across the region. Warm, humid air and this lingering front will provide a daily chance of scattered/heavy storms into next weekend.
