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.

Wednesday: Potential Of A Busy Severe Weather Day…
Highlights:
- Stormy Wednesday
- Snow mixes with rain Thursday
- Gorgeous weekend upcoming
- Busy times return next week
Remain Weather-Aware…Chilly, dry weather will continue this evening before showers and thunderstorms (non-severe) approach the western Indiana state line overnight and early Wednesday. Initially, showers and thunderstorms will impact western and northwestern portions of the state before all of central Indiana gets into the act by the afternoon hours. We continue to be concerned for the potential of an active severe weather day across the southern half of the state. All modes of severe weather will be possible, including tornadoes. As of this update (late Tuesday night), the greatest risk area appears to lie within areas from Indianapolis and points south and southeast. We’re most concerned for the period 2p-8p and will fine tune things early Wednesday if needed. Please remain weather-aware and have a means of getting the latest warnings.
We’ll shift gears rather abruptly from severe to more of a wintry feel to close the work week. Much colder air will spill into central Indiana Wednesday night and Thursday and leftover, wraparound, moisture will begin mixing with wet snowflakes Thursday afternoon and evening. Gusty northwest winds and the unseasonably chilly air will result in a downright ugly, raw day.
After early morning snowflakes Friday, drier air will begin to work into the region and result in increasing sunshine Friday afternoon. This will be a prelude to a gorgeous weekend: After a cold start Saturday, expect lots of sunshine and moderating afternoon temperatures. The warming trend continues Sunday as we top the 70° mark.
Our next storm approaches early next week. Clouds increase Sunday night and give way to showers and thunderstorms Monday into Tuesday. Questions come into play in regards to timing with this next cold front, but thinking (as of now) only slowly moves the front along, keeping unsettled weather in our forecast early week before a much cooler, drier period of weather by midweek.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 2.00″ – 2.50″
