Storm chances to return with cooler air to follow

Monday evening forecast – September 4, 2023

INDIANAPOLIS (WISH) — After a hot and humid start to the workweek, Storm Track 8 is tracking a couple of disturbances that will bring the best chance for rain we’ve seen in a couple of weeks.

Beyond midweek, we are eyeing a cooldown and drop in the muggy meter.

Monday night: It is going to be a very warm and muggy night under partly cloudy skies. Don’t expect temperatures to drop off a ton as numbers only back down into the mid 70s.

Tuesday: The heat and humidity will continue to hold on, with dew point values pushing further into the low to mid 70s. This will make people feel miserable with heat indices in the mid 90s. In conjunction with the hot and humid airmass, a weak disturbance will swing by and aid in the potential for scattered showers and storms in the afternoon and evening. A few showers may linger into the night. Severe weather was not expected.

Actual air temperatures will peak in the upper 80s to low 90s.

Wednesday: We’re set to work in a forecast transition point through Thursday. A stronger system will arrive with a cold front that will bring more scattered rain and storm potential. This will also increase winds with gusts from 20-30 mph at times. Ahead of the front, a hot and humid airmass will lead to some unstable air building.

There is even a low chance for isolated strong to severe storms Wednesday afternoon. The primary threat will be damaging winds.

Before the front slides through, highs will rise into the mid to upper 80s. Dew point values will be the same as they were Tuesday.

8-Day Forecast: The aforementioned transition point will complete its process Thursday as Indiana welcomes back cooler and refreshing air. Winds will also turn out of the north and stay breezy with highs only getting into the upper 70s to low 80s. Friday will feature a nice end to the workweek with temperatures in the upper 70s. Indiana looks to stay on pleasant through the upcoming weekend with highs in the low 80s and lots of sunshine.
