While not “overly cold” (at least yet), we’re heading into a special pattern for snow/ winter weather lovers. After the leading wave of accumulating snow over the weekend, a much more “meaningful” storm eyes the region late tomorrow night and Wednesday.
In short, we don’t have any changes to our thinking since Saturday on this storm. Snow will lift in here from the south during the overnight and become heavy throughout the morning hours. Snowfall rates will likely approach, if not exceed, 1″ per hour during this time period and will lead to a horrendous morning rush all throughout the region. If you don’t absolutely have to travel, we recommend staying put. Embedded intense snow bands will likely pivot into the city throughout the morning, elevating those snowfall rates and reducing visibility.
Heaviest snow looks to fall in the 2a to 11a timeframe in the city, itself. This will be a wet, heavy (paste-like) snow.
We still don’t see a reason to alter our ongoing snowfall forecast published first to Clients Saturday. This is only for the Tuesday night-Wednesday period and doesn’t account for additional light snow accumulation that will take place Thursday into Friday. Needless to say, there will likely be some across central Indiana that close in on double-digit storm totals by the time all is said and done.
And just as soon as we catch our breath from this storm, attention will turn to the following winter weather makers:
2. Another southern stream system approaches Saturday evening. While milder air will be present (at least aloft), it’s also very possible the modeling will be forced to correct colder after realizing what kind of deep snowpack will likely be deposited across the region midweek. Long story short, we feel this storm system will also be capable of producing a wintry mix of snow and/ or sleet and freezing rain Saturday night into Sunday. Additional details will have to be sorted out in more specific fashion after midweek.
Thereafter, with the negative PNA and negative EPO in place, we’re likely to deal with additional wintry “fun and games” into the middle and latter part of next week, but with this being more than 7 days out, there’s no reason getting too excited from this point with specifics.
Needless to say, we’re in about as good of a position as one could ask for accumulating winter weather events in the medium range period. We’ll just have to take one storm at a time.
Make it a great evening!

Type: Impactful wintry weather
What: Impactful wintry weather
When: Tonight and Thursday morning and Thursday afternoon through predawn Friday
Temperatures: Middle 20s to lower 30s
Wind: East Northeast 10-20 MPH, shifting to the north late Thursday
Blowing/ Drifting: Minimal across n-central Indiana
Pavement Impacts: Plowing and salting will be required across n-central Indiana and points north. Salting required across southern and central Indiana.
Summary: (2) waves of moisture will stream over central Indiana between this evening and predawn Friday. The initial, lead wave of precipitation will feature a mixture of light snow, light sleet, and light freezing rain. “Light” is the key word, but area roadways will likely become slick through the evening and into tonight- including in and around Indianapolis-proper. In and around the I-70 corridor and points north, this precipitation is expected to primarily fall in the form of snow. Further south, a mixture of sleet and freezing rain is anticipated. While this will be light in nature, precipitation should be rather persistent, lasting up until, or just after, sunrise. By sunrise, areas in and around Indy and points north can expect between 0.50″ and 1.50″ of snow (should sleet mix in, amounts will be closer to the lighter end of the spectrum vs. if we stay mostly snow, amounts closer to 1.5″ can be expected). Further south, a light glaze (up to 0.1″) and light sleet is expected to be the predominant precipitation type with this initial wave of moisture.
We’ll then undergo a “lull” in the action mid morning into the early afternoon hours, but low pressure will be organizing off to our southwest and have eyes set on a northeast trek into the southern portion of the state Thursday evening. This will be when we anticipate the heavier precipitation to move across the region. Across southern IN, this should primarily fall in the form of a cold rain, but further north the same can’t be said: a wintry mix of sleet and freezing rain is expected to redevelop Thursday afternoon and continue into the night before ending as light snow. Across n-central IN and points to the MI/ IL state line, all snow is anticipated.
Precipitation will diminish from southwest to northeast predawn Friday with high pressure regaining control of our weather to close out the work week (just a few light lingering snow showers are expected Friday). Please see our updated snow and ice forecast below that includes total amounts for both parts of this event.
Confidence: High
Next Update: 7:30a Thursday

As we analyze downstream radar trends and fresh high resolution, short-term guidance, it appears as if the initial burst of precipitation is speeding up. It now looks like a mixture of light snow and light sleet will arrive into central Indiana between 7p and 10p.
Along and north of the I-70 corridor, this should fall primarily as snow (up to 1”). Further south, a mixture of sleet and freezing rain is expected this evening (where things remains all freezing rain, a light glaze, perhaps up to 0.1”. is expected to develop on elevated surfaces by sunrise).
Our updated client brief will be posted later this evening and include additional thoughts as the 12z data streams in.

Updated 02.22.22 @ 5:21p I. After digesting the 12z model suite, it continues to look like an impactful winter event is still slated to impact the state Thursday and into…

While we still need another day or two to hammer out specific numbers, here’s the early thinking around precipitation type with system #2 (Wednesday night into Friday morning).
