Severe Weather Sunday; Much Colder Next Week…
Highlights:
- Clouds more bark than bite today
- Stormy setup Sunday
- Trending colder next week
All Eyes On Sunday…The cold front that passed through the region Thursday night and setup the gorgeous close to the work week is lifting back north this morning as a warm front. This will result in overcast conditions today, areas of sprinkles or drizzle later in the day, and rising nighttime temperatures. Scattered thunderstorms will develop across central Indiana late tonight with a warmer and increasingly moist environment.
Sunday will certainly be a day to remain weather-aware. The overall setup hasn’t changed from what was discussed yesterday with a warm and moist southwesterly air flow in place ahead of an approaching cold front and associated area of low pressure. Additional ingredients in play suggest we need to monitor the threat of large hail, damaging straight line winds, and potentially tornadoes. Individual storms (potential super cells) are expected to fire across central and northern portions of the state Sunday afternoon into early evening. These will be capable of quickly pulsing to severe levels and include potential of large hail, as well as tornadoes (particularly in the vicinity of the warm front which is expected to be draped across north-central parts of the state). Individual cells are anticipated to “morph” into a squall line Sunday evening, including potential of a quick spin-up tornado, as well as damaging straight line winds. With a moisture-rich air mass in place (precipitable water values are expected to approach 2″ Sunday evening), locally heavy rainfall is also expected.
All of our “excitement” will come to an end overnight Sunday and we’ll trend much colder (and calmer) during the new work week ahead. Our next storm system will pass by to our south Tuesday, but may be close enough to spark a light shower across central portions of the state. Drier and colder conditions build in later in the week.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 1.50″ – 2.50″

Growing Severe Threat Sunday…
We have growing concerns of a severe weather event Sunday afternoon and evening across the state. This morning, the Storm Prediction Center (SPC) has included most of Indiana in an “Enhanced” risk of severe weather. From this distance, all modes of severe weather seem possible, including large hail, damaging winds, and even a tornado or two.
A trough and associated cold front will slice into an unseasonably warm and increasingly moist air mass Sunday. Ahead of the approaching front, temperatures should climb into the lower 70s Sunday afternoon (average high is in the upper 50s) and dew points will reach the lower to middle 60s. While the developing surface low isn’t expected to be terribly strong, as this feature moves northeast, it’ll help drag a cold front into this warm and increasingly unstable air mass late Sunday. From this distance, conditions seem favorable for a couple of super cells to develop Sunday afternoon and evening. We’ll have to keep a close eye on the northward extent of the warm front as this would be the areas of greatest concern for potential tornadic activity Sunday afternoon. Large hail and damaging winds are also included in Sunday’s severe threat. We’re in the second severe weather season, after all, and this kind of event isn’t unusual. Late November 2013 comes to mind.
It’ll be important to remain weather-aware Sunday and stay tuned all weekend for future updates. We’ll transition to a much cooler regime (back to below average) next week.
A cold front will slice into unseasonably warm and moist air Sunday afternoon and evening. A severe weather episode is a growing concern. Remain weather-aware.

Warm Saturday; Storms Rumble In Late…
October has gotten off to a warm start (+ 8.4° at IND, to be exact) and that will continue this weekend as high temperatures top out between 80° – 85° Saturday.
October has gotten off to a warm start across the Mid West.
In addition to Saturday’s warmth, southwest winds will gust over 35 MPH at times- especially during the afternoon hours.
Most of Saturday will remain rain free, but we’ll need to keep an eye towards the western horizon Saturday afternoon as a frontal boundary helps kick up a line of thunderstorms.
The Storm Prediction Center (SPC) includes a large portion of Indiana under a marginal risk of severe weather Saturday. While widespread severe weather isn’t anticipated, a couple of embedded gusty storms are a good bet Saturday afternoon and evening.
The biggest concern with stronger storms is gusty straight line winds. While the line of storms should be relatively “skinny,” don’t be surprised if one or two of the storms requires a warning. Here’s an idea of what the radar may look like around 9p Saturday.
We’ll turn less humid and slightly cooler for the second half of the weekend!

VIDEO: Severe Potential Tonight, October-Like Chill, And Irma…
The Storm Prediction Center includes an Enhanced Risk of severe weather across north-central parts of the state this evening. Damaging winds are of greatest concern with the stronger storms embedded in a squall line that will move from north to south this evening (generally between 6p-midnight).
MUCH cooler air will descend into the region as we progress through the week. Temperatures will be so cool, it’ll feel more like October rather than September, including multiple nights with lows settling into the 40s and highs not making it out of the 60s.
