No doubt an autumn feel and look to the weather in central Indiana Tuesday with temperatures stuck in the 60s under a mainly cloudy deck of cumulus. In fact, there's enough instability and lift (with an upper disturbance) to squeeze-out spotty "instability" showers/hailers.
After sunset the atmosphere stabilizes as surface temperatures cool and the heating differential relaxes. This allows clouds to clear for another seasonably chilly night in the 40s.
Get ready for a windy Wednesday and warmer too as highs climb into the 70s. Gusts during the afternoon could exceed 40 mph at times so use caution if you're traveling in a high profile vehicle or plan to be out on the lake.
Additionally, spotty showers/storms in the afternoon/evening both Wednesday and Thursday. We're still on target for even colder air to arrive Friday into Saturday morning...with some frost potential depending on cloud cover.
Modeling continues to paint a gray, damp, and chilly picture for Sunday with a growing likelihood of showers and below average temps.
