Data is not looking good for immediate Aurora in Indiana at this time. The Northern Lights are still possible later tonight in short bursts. - 12:29am EDT

09/02/2025

Aurora Update -9:15pm ET.
Northern lights are still possible, mainly Northern IN. The storm has hit however the lights are staying well North of Indiana at this time as we are waiting for a southward push/ -BZ. Right now our spread is BT +20 and a BZ of +4. We like to see that BZ get well below 0 for example -20. The further the BZ is negative the further the southward push.

While we are in a waiting period, the Northern lights are still possible tonight. We dont think it will be a constant show but rather come in short durations south.

Stay tuned for updates! We will post when Aurora is imminent and to head outside!

August was the first month since February with no tornadoes in Indiana! 😁

Cloud cover tonight!

The Northern lights are possible tonight with best viewing conditions North of Indianapolis. Cloudy skies will be present across Southern indiana likely in the form of high level clouds. Aurora may still be visible in Southern Indiana if clouds are thin or broken.

Currently there is no set time for the Aurora to occur or if it will occur at all. Data is trending in the right direction! We are awaiting the arrival of the CME. Our latest thoughts are that the lights may be visible on the horizon with camera only. Naked eye visibility is possible however, this will greatly depend on how data evolves. We will post updates as data becomes available.

Stay tuned for updates today! Our fingers are crossed!

⚠️ An arctic cold front will bring a polar airmass straight from the arctic circle!

The coldest airmass of the season will arrive Wednesday night through the end of the week. Gusty winds may be present Wednesday night into Thursday. Temperatures will be up to 20°F below average!!! Daytime highs may not exceed 65-68° on Thursday anywhere in Indiana!

We are watching for a non 0 risk for patchy frost depending on how this airmass evolves. If a frost does occur it will have some agricultural impacts! Frost will damage or kill any late flowers on soybeans! While the risk is low for a widespread frost, there is a non 0 risk and is worth mentioning.

Northern lights are *POSSIBLE* tomorrow night scross parts of Indiana!

-What-

A large M flare was observed yesterday from the sun and produced an earth directed CME (Coronal Mass Ejection). This wave of charged particles and intense solar wind is modeled to impact Earth Monday evening into Monday night at the earliest. There is a chance it arrives later on Tuesday morning.
Timing is very important as this can mean the difference between No- Aurora and Aurora. If the CME arrives Monday evening it will give us in North America the best chances at seeing the show. If the CME arrives late on Tuesday morning we will be on the sunlit side of the Earth which will favor Europe and Asia for the best chances.

Right now a G3 watch is in affect as G3 conditions are possible Monday night into Tuesday. Persons in Northern Indiana will potentially have the best chances at seeing the Aurora on the horizon. More than likely this will not be visible with the naked eye and will be a camera only event. But, that could change depending on how the event evolves.

Persons south of Indianapolis are not expected to be able to see the Northern lights. Although unlikely, there is a non 0 chance that Aurora may be allowed to briefly push south to be viewed by persons in Southern IN. This scenario would likely be caused by a substorm which is a sudden release of built up energy. Substorms can briefly and quickly send the lights south before retreating north. These come with little warning and last for short periods of time (5-15 minutes)

-TIMING-

There is NOT an exact arrival time for when Aurora will be visible. Aurora is ever evolving and times will not be known until the CME has impacted our planet and data is analyzed. If Aurora looks to be visible in Indiana we will post updates to help maximize your chances of seeing it!

Average tornado risk for September based on historical averages!

While September is not typically a very active month for severe weather in Indiana, it can still occur! In fact we can and have recorded tornados in all 12 months of the year in Indiana as severe weather can occur anytime of year here!

Muggy meter!

No disrespectful humidity near term! We will see some moisture move in on Wednesday ahead of an strong cold front before dew point values fall off a cliff into the mid 30s! This is nose bleed criteria here!
