1.) A big ole ridge will supply oppressive heat and humidity across the Mid West this weekend. Unseasonably hot temperatures will combine with downright “soupy” air to create heat indices between 105-110 degrees across central IN this weekend. Take it easy and implement frequent breaks if your plans take you outdoors.
2.) Similar to what we’re seeing on radar this evening, thunderstorms will also make an appearance from time to time for some. With an atmosphere loaded with moisture, any storm that develops will be plenty capable of producing “frog straggler” type rainfall rates. Perhaps there will be a couple periods of more concentrated storm activity, focused on late tomorrow night and early Saturday, and again late Saturday night-Sunday morning. We’ll keep an eye on things.
3.) The pattern is one (as has been the case all summer) that’s transient and the situation that develops to wrap up July and open August is an all-too-familiar look around these parts: NW flow aloft that offers storm potential, along with seasonal to slightly warmer than average. It’s a wet look, overall.

This is what the upper air pattern should look like as we close July- 10 days from now (hard to believe)!
4.) Looking further ahead, the latest JMA Weeklies continue to suggest the most sustained hot pattern should remain across the west as we rumble deeper into August. That’s not to say we won’t deal with periods of hot weather here at times, but sustained heat will be hard to come by with such a pattern…
