Highlights:
- Foggy days
- Late week winter storm
- Much colder air returns
Low Beam Weather…Widespread low clouds, fog, and areas of drizzle will impact the region as we progress through the next couple days. If venturing out early this morning, be extra careful as sub-freezing temperatures combined with the moisture has created slick spots- particularly on side streets and sidewalks.
A southerly flow will take control briefly Wednesday evening into Thursday and help lead to a quick “thaw,” along with more widespread rain showers Thursday. This is in association with a cold front that will sink south through the state Thursday night into Friday morning. As this is taking place, an area of low pressure is expected to develop along the tail end of the cold front and track northeast. That low will spread moisture back into what will be an airmass turning much colder Friday into Saturday. The end result will be a potentially significant event of an icy mix (sleet and freezing rain) transitioning to snow Friday into Saturday. Much colder air will pour in here over the weekend and additional upper energy will result in widespread snow early next week.
If you have travel plans Friday into Saturday, please keep abreast of the latest forecast. A significant event looms, but we’re still a couple of days from being able to put the heaviest snow zone in “concrete.”
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 3″ to 6″
- Rainfall: 0.50″ to 1.00″

Highlights:
- Brief midweek thaw
- Late week winter storm threat
- Much colder air returns
Take It Slow This Morning…An overnight mixture of sleet, freezing rain, and snow has created a few slick spots, but widespread travel issues haven’t been reported this morning. Thankfully, even a 1° to 2° difference (milder) in surface temperatures overnight helped us out in that regard. The wintry mix is heading out and we should even see a little sunshine later today.
As temperatures settle back below freezing tonight, concern is present for the possibility of freezing fog and freezing drizzle in spots into Tuesday morning. A warm front will then lift north through the state Wednesday helping our brief midweek “thaw” get underway in earnest. Showers will accompany the milder conditions into Thursday.
A cold front will settle south through the state Thursday night and colder air will press southeast. At the same time, a secondary area of low pressure will develop along the tail end of the front and lift northeast into the Ohio Valley Friday evening into early Saturday. While this has the sure sign to be a significant, impactful winter storm, we’re obviously still a couple days away from being able to nail down precise track and strength. Stay tuned and keep close tabs on that Friday-Saturday forecast. We’ll turn much colder once again over the weekend.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 2″ to 4″
- Rainfall: 0.50″ to 0.75″

Highlights:
- Messy wintry mix arrives tonight
- Briefly milder midweek
- Potential storm brewing Friday
Snow And Ice Arrive Tonight…Clouds will lower and thicken across the state as we progress through the day. We’ll also note a stiff easterly breeze as an approaching storm system inches ever so much closer. This storm system will spread a wintry mix through the state tonight into early Monday morning. Initially, we think most of central Indiana will deal with snow before a transition to freezing rain during the overnight, continuing into Monday morning. Before the transition, 1″ to 2″ of snow seems to be the best idea before an icy glaze develops atop the freshly fallen snow. Based on the expected transition to freezing rain, there’s an opportunity for up to a tenth of an inch of freezing rain. That said, we’ll have to keep a very close eye on temperature profiles this evening as even the difference of a couple of degrees aloft can make all the difference in a faster or slower transition to freezing rain. Expect the Monday morning commute to be heavily impacted.
Colder air will push back in here Monday evening into Tuesday with considerable cloudiness remaining. A milder southerly flow will overtake the region Wednesday into Thursday. Low clouds and fog along with drizzle will develop Wednesday and we may have to deal with a touch of freezing drizzle early in the day before temperatures rise. A spike in temperatures will take place Thursday, briefly sending central Indiana into the 50s before a cold front slides through the state Thursday evening.
An area of low pressure will develop along the southern end of the frontal boundary and lift northeast into the TN Valley and eastern Ohio Valley Friday. As colder air presses into the region, precipitation will change from a wintry mix of sleet and freezing rain to all snow through the day Friday. It’s far too early to get specifics around accumulation ideas, but this storm has potential to be significant. Much colder air will whip in here next weekend.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 2″ – 4″
- Rainfall: 0.50″ – 0.75″

Highlights:
- Bitter cold eases
- Mix of snow and ice
- Milder midweek
Bitter Today; Wintry Mix By Sunday Evening…Most central Indiana reporting sites are checking in this morning between 6° and 10° below zero, but we note a couple of spots are even colder. Arctic high pressure will remain in control of our weather today, leading to sunny and bitter conditions.
An approaching storm system Sunday will help increase our cloud cover through the morning and we expect snow to develop by evening. As warmer air aloft works into the region, a transition to freezing rain is expected during the overnight into early Monday morning. The morning commute looks very messy Monday.
Moderating temperatures will develop by midweek and as the milder air moves over the cold surface, thick fog and areas of drizzle and light rain will develop Wednesday. A cold front will sweep through the state Thursday with showers and we’re keeping close tabs on a secondary piece of energy that will lead to a wintry close to the work week for portions of the Ohio Valley. In fact, a significant winter event should develop out of this pattern Friday into Saturday. The early call for now is that this is east of our region, but stay tuned. Snow showers will fly in the colder air to close the week regardless.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 1″ – 2″
- Rainfall: 0.50″ – 0.75″

Highlights:
- Fresh batch of arctic air served up
- Watching Sunday
- Moderating next week
Brutal Cold Continues…A fresh batch of arctic air arrived into the Hoosier state last night. This will set the stage for an absolutely frigid close to the week. Wind chill values will periodically reach dangerous levels between now and Saturday morning. Additionally, we’ll add a few more mornings to the sub-zero club in what’s already an impressive list this winter.
Attention remains on a developing storm system that will impact our region Sunday into early Monday. We forecast a lowering and thickening cloud deck to arrive overnight Saturday into Sunday morning, followed by a wintry mix Sunday afternoon and evening. Messy wintry precipitation should continue into early Monday before precipitation departs to our east. Data, overall, has trended colder over the past 24 hours and would lead to more impact from snow and less ice. Stay tuned.
Drier times return early next week along with moderating conditions ahead of the next storm system that will approach late next week.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 1″ to 3″
- Rainfall: 0.00″
