Ingredients In Place For A Significant Severe Weather Episode.
Quick update this morning, but a more extensive discussion will hit the site later this afternoon/ evening.
An initial round of strong to severe thunderstorms will move through central Indiana this morning as a warm front crosses the state. After morning storms rumble through central Indiana the majority of the day will be rain-free and turn downright hot and muggy. An oppressive feel to the air will develop this afternoon as dew points rise into the 70s. We’ll then target another (more widespread and intense) outbreak of severe weather late tonight into the wee morning hours Sunday.
The Storm Prediction Center has placed the region under a moderate risk of severe weather today:
The ingredients are in place for a significant severe weather episode later tonight…
Big picture overview:
An autumn-like cold front will slice into a very warm, humid, and unstable air mass Sunday. Individual disturbances out ahead of the cold front will combine with ingredients listed below to potentially lead to a rather widespread and dangerous severe weather outbreak tonight.
Additionally, short term model data forecasts…
- CAPE (Convective Available Potential Energy and an ingredient of what helps fuel a thunderstorm) to reach 4000-5000 J/kg. Anything over 2000 is enough to lead to strong storms should other factors be in place.
- Dew points to climb into the lower and middle 70s.
- Precipitable water to reach 2.5″ (suggests a flash flood threat and local microburst potential)
The greatest concern has to do with the potential of a widespread damaging wind event late tonight into the wee morning hours Sunday, but concern is also present that a couple of super cells could develop in advance of the more widespread complex of storms. Within these super cells, an opportunity is there for large hail and a tornado potential and we’ll closely monitor this as well.
Much more later this afternoon!

We’re keeping a close eye on showers and thunderstorms to our northwest (across Iowa and Minnesota) this morning as these will continue to drop southeast with time today. We know we’ll see clouds increase locally from this complex of storms and some of the latest short-term model data brings in light rain during the afternoon as the complex drops southeast into IL and IN- though in a much weaker state. We’ll include mention of an afternoon shower due to this.
As we move into the weekend concern remains around the possibility of multiple thunderstorm complexes impacting our area. The Storm Prediction Center includes us in a Slight Risk of severe weather Saturday and Sunday, including the chance of some storms producing a damaging wind and hail threat. We target Saturday morning and again Saturday night and Sunday for the best chances of thunderstorm complexes. Saturday night/ Sunday morning may provide the greatest risk of severe storms, and we’ll continue to monitor. We also note high precipitable water values present this weekend suggesting the threat of some localized flooding where storms train. Widespread 1″ rainfall can be expected this weekend, but we do caution some areas will see locally heavier totals in excess of 2″.
A much cooler, drier and fall-like feel is still slated to blow into town early next week, setting the stage for an incredible close to July and open to August!
