Are you liking the mild air? The temp early this morning dipped to 51° in Indianapolis. It's the coolest low temperature the slate in June in 11 years. Coolest locations dropped to 46° at Crawfordsville, Lafayette and Peru!

ADI Low temps

The dry air holds for now and dry air heats quickly. A 30 degree change in many locations since this morning as afternoon temps reached mid 70s. The normal high is now 80° and will remain 80° or higher through September 11th.


The heat is on the way soon. The long advertised rise to 90° + air follows a passing warm front late Thursday into Friday morning. The combination of a nighttime jet stream, the intersection of heat and humidity is favorable for clusters of storms to form.

A batch or 'complex' of gusty storms is possible late Thursday into Friday morning. We will carefully monitor Thursday. SPC (Storm Prediction Center) has out looked a portion of Indiana for a 'marginal' risk of severe storms.

FIRST 90° DAYS OF 2016

Indianapolis averages 19 90° days each year with the first occurring June 14th.  The heat is about right on track.  The heat swells and moves east starting Thursday. The early season dome of heat brings the first 90° day and possibly a heat index near or above 100° by Saturday! Enjoy the mild air for one more night. The humidity will surge soon!

Be sure to follow along with me at Twitter for more updates throughout the afternoon and evening each day!
