A band of light showers is falling across southern Indiana this morning, but these are expected to diminish before pushing into central Indiana. Most of the remainder of our Wednesday should be rain-free.
The quiet times will give way to a couple of rounds of storms during the overnight and into Friday. Most notably for central Indiana, we think storm chances will increase significantly after midnight and through the predawn hours Thursday. Locally heavy rain and vivid lightning is expected with the stronger storms.
These storms are in association with a warm front lifting north through the state. Speaking of warm, we’ll certainly notice a difference in air masses between today (still relatively cool and dry) and tomorrow (much warmer and more humid). In fact, highs Thursday will flirt with 80° across most of central Indiana.
Once we get rid of the early morning storms, most of the remainder of our Thursday will be dry and feature a return of the sun.
Another round of storms is expected Thursday night into Friday, but most of these will remain well north of our area. A few of these could become severe across northwestern Indiana during this period.
Rain and storm chances will increase once again during the day Friday across central Indiana. A few strong storms will be possible.
As we look ahead to the weekend, it appears we’ll be able to enjoy a mostly dry day Saturday (widely scattered storm possible) before more widespread storms return Sunday. Warm and humid conditions will prevail. A cold front will move through the area early next week which will allow for briefly cooler, drier air to move in during the 1st half of next week. Before that takes place, rainfall amounts between tonight and Sunday are expected to range from 1.5” – 2” with locally heavier totals across central Indiana. Heavier rainfall amounts can be expected across northern Indiana (widespread 3” to 4” amounts during the same period).
