Updated 08.23.23 @ 7:50a While the heat and humidity grab headlines (and rightfully so), we’ll have to keep close eyes on the potential of outflow boundaries offering up some cooling…

A quiet start to the day will give way to a noisy lunchtime period as a line of thunderstorms drops in from the northwest.
Vivid lightning, brief gusty winds, and heavy downpours can be expected.
The Storm Prediction Center has hoisted a ‘marginal’ risk of severe today. Widespread severe weather isn’t anticipated with this frontal passage.
Our unseasonably cool, pleasant airmass we’ve enjoyed the past couple days will be reinforced with this frontal passage. Lows tomorrow and Saturday morning will dip into the upper 40s in outlying areas. Dry and sunny conditions will compliment the early fall-like air. Soak it up as a period of unseasonably hot weather still awaits next week.
The byproduct of the sprawling ridge above? A week ahead with highs well into the 90s and an extended period of dry, sunny weather.
Despite a few light morning showers, our Sunday will feature dry conditions through the remainder of the daylight hours along with increasing sunshine. The disturbance responsible for Saturday’s severe weather and unsettled conditions is on the way east while we wait a new potent disturbance on deck from the west. Unfortunately, this second disturbance has eyes set on our region tonight and will pose a dangerous overnight severe weather risk.
All modes of severe weather will be possible, including damaging winds, large hail, and a couple of quick spin-up tornadoes. It wouldn’t surprise me if a portion of the current ‘Slight Risk’ area is upgraded to an ‘Enhanced Risk’ across southern IN in future SPC (Storm Prediction Center) updates this afternoon.
From a timing standpoint, storms should approach western Indiana towards 10p, or so and then continue to advance east, southeast into the late evening and overnight hours.
Discrete cells may try and organize into more of a congealed line as we push closer towards midnight and, as such, the threat of a damaging wind event will become the eventual primary concern as we move through the early Monday morning hours across the southern half of Indiana.
Before heading to bed this evening, be sure to have a means of getting the latest warning information as there will likely be multiple warnings issued late this evening and into the early portion of the overnight.
Quieter (albeit briefly) weather conditions will return as we move through the first couple days of the new work week.
