In the extended forecast, we are tracking 2 more rounds of arctic air. The first will arrive later Sunday and drop temperatures below zero Monday and Tuesday mornings. The second will be here later Wednesday and drop temperatures below zero Thursday and Friday mornings.
There is another chance for snow along that arctic front Tuesday night.
All of central Indiana is now under a winter storm warning from 7pm Friday through 7pm Saturday. Snowfall potential is 3-6+ inches. We will be tracking this hour by hour for you through Saturday night. Right now we are forecasting the steadiest snow to fall from about midnight through 7am Saturday, with another wave possible during the afternoon. I will have updated timing a little later this afternoon, so stay tuned for updates.
The arctic air is somewhat easing, and now our attention is turned to accumulating snow in Central Indiana this weekend.
Highs will reach the low 20s today with mostly cloudy skies, there could be a few flurries or snow showers too.
Tonight winter storm warning and advisories go into place.
Our main chance for snow will ramp up tonight. After 10pm snow is expected to move in and last through Saturday afternoon. Here’s how the hour by hour forecast plays out through FutureTrak13.
It does appear that sleet / ice / rain could mix in, in our southern counties, if that happens, snow totals will be reduced there. We will be watching this very closely. This is our latest thinking of snow totals, again, this could change depending on the type of precip that falls.
The take away from this forecast is that travel Saturday will be messy. Expect slick roads, limited visibility and changing conditions if you are doing any long distance traveling.
In the 7 day forecast, another arctic blast is headed our way early next week.
It’s definitely rare air across Central Indiana. Indianapolis was just shy of tying a record low this morning, and the city will break the record cold high for this date. In fact… this is the coldest high this late in the season since 1963.
Adding insult to the cold the misery are the dangerous wind chills that have hovered around -10 to -20 all afternoon. They’ll remain bitter this evening but the wind overall will diminish tonight. But the Wind Chill Advisory continues until 11am Friday. The lighter wind allows greater raditional cooling tonight and lows will be much colder in some locations.
The lighter wind allows greater raditional cooling tonight and lows will be much colder in some locations. We’re anticipating much of south central Indiana to be the -10 to possibly -20 range for actual temperatures. This is due to deeper snow pack in this area. Indianapolis’ forecast low of -7 will challenge the daily record set in 1885.
Highs Friday will be “warmer” but significantly below the average which is the lower 40s for late February. Temperatures climb into the upper teens and lower 20s and won’t drop Friday night due increasing overcast.
Light snow is possible by sunset tomorrow and we’re still in play for accumulating snow and/or ice in the viewing area. The timing would be Friday night into Saturday evening. Please note there is high uncertainty on track and significant divergence in model solutions at this point. We just can’t get to specific about timing and amounts. However I will say that most model solutions today show a weaker, more suppressed, system than prior runs… and have shifted the more “juicier” moisture fields farther south across Kentucky.
Regardless of strength… all models advertise a quicker system that departs by 12am Sunday. This will be followed by another impressive shot of bitter air next week. We’re staring down multiple mornings in the single digits and a few below zero again too.

Snow showers and locally heavier squalls linger for another few hours. Slick roads can be expected even after snowfall ends due to considerable blowing and drifting. Temperatures tumble to the coldest levels of the winter tonight and near record low levels by sunrise.
All of the region is under a Wind Chill Advisory from now until 11am Friday. Wind chills drop into the -20 to -30 range overnight into Thursday morning. Very bitter conditions for anyone outside tomorrow with wind speeds of 10 to 20mph… with potentially higher gusts.
Lows Thursday morning will be close to the record of -8 set back in 1979. The record cold high tomorrow will be smashed! In fact if our forecast high of 5 degrees verifies… it will be only the 9th day that cold (for a high) in the past 30 years. It would also be the coldest high for Indianapolis this late in the season on record.
A changing wind direction pushes snow squalls much farther Thursday, but be mindful that vigorous lake squalls impact I-69 and the Toll Road in northern Indiana. Light snow returns to the area Friday afternoon and we continue to monitor a bigger system.
Many have asked about the weekend storm potential. Model guidance continues to advertise a “juicy” system still eyeing Central Indiana. All precipitation types are on the table including accumulations of snow, wintry mix, freezing rain and cold rain. “If” heavy rain materializes we can’t even rule out flooding due to snow melt. This far out it’s premature to be more specific than that. We’ll update as needed. Check back and stay safe this evening – Sean Ash
Vigorous snow showers and squalls are dotting Central Indiana. Be prepared for rapidly changing road conditions, localized white-outs with pockets of accumulation exceeding one inch. The squalls are also accompanied by gusty 30-45mph wind. Remember while it may be sunny when you leave home, driving into a squall can happen with very little warning.
Squalls and snow showers settle down and diminish after sunset. Then we prepare for record cold temperatures Thursday with dangerous wind chills. Afternoon wind chills remain parked below zero and drop into the -20 to -30 range by sunrise Thursday… which nears Warning Criteria. We’re advising you to limit outdoor time this evening and into midday Friday as Wind Chill Advisories continue to 11am Friday.
Indianapolis nears a record low tonight and will smash a 130 year old record cold “high” tomorrow. “If” our forecast high of 5° verifies tomorrow it would mark the coldest high this late in the season on record for Indianapolis. The last time the city had a high of below 7° this late in the season was 1963. It’s rare air anyway you slice it.

Temperatures will be around 10 degrees early Wednesday and won’t move much throughout the day. It will be windy, with winds WNW 15-25mph. This will bring wind chills down into the range of -5 to -15 during the day Wednesday. There will still be a few bands of snow that will reduce visibility and cause slick roads through Wednesday evening.
Temperatures will fall to near -5 Thursday morning and wind chills will be -10 to -20. Highs on Thursday will only be in the single digits. Temperatures go below zero again on Friday morning and highs on Friday will be near 15 degrees. Both Thursday and Friday will be dry.
We are tracking a developing weather system for the weekend. There are still lots of question marks including type of precipitation, track and temperature. We will keep you updated. Right now we have a wintry mix in the forecast for Saturday and snow chances on Sunday.
