One More Day Of 90s And Record Heat

This is day three in a row of record-breaking heat with highs expected to be near/above 90° this afternoon. For many areas this will be a carbon-copy of the past two days... breezy, unseasonably hot, and mainly sunny.

However, a frontal system approaching north-central Indiana does at least bring a chance, albeit 20-30%, of spotty showers and/or storms during peak-heating hours from noon to 6 PM. But a lot of places won't have a drop rain... not only today but over the next week.

Thursday remains our transitional day with the aforementioned cold front moving across the viewing area. Unfortunately this front has limited lift due to the jet stream being well to the north... so only spotty sprinkles or a passing shower possible.

We expect high temperatures in the Indy metro area Thursday at around 80° to occur around 11 AM - 12 PM before FROPA (frontal passage) and a wind shift to the northwest. Clouds and wind increase with gusts at times possibly exceeding 30 mph... helping drive temperatures into the 60s/70s around central/north-central Indiana and dropping the Muggy Meter well into the comfortable range with dewpoints in the 40s/50s.

A steady north-northeast pushes temperatures to near 50° Friday morning in what will look and feel like autumn. Scattered to numerous low clouds will be undercut by a northeast wind to keep high temperatures in the 60s Friday. Clouds clear with a steady northeast wind Friday night as temperatures drop into the 50s by end of Operation Football games.

Saturday morning begins with lows in the 40s but highs shoot into the mid-70s during the afternoon with a mix of sun and clouds. Another weak front arrives Saturday night and provides a low chance of scattered light showers into Sunday morning. But right now we believe much of Sunday will be rain-free after 10 AM.

This front does reinforce seasonably cool air next week with highs in the 60s and lows in the 40s.
