Client Brief: Time To Gas Up The Snow Plows…
Type: Impactful Wintry Weather
What: Accumulating snow and sleet
When: Wednesday afternoon through Thursday evening
Temperatures: Lower 30s falling into the 10s by Thursday evening
Wind: Southeast 10-15 MPH Wednesday afternoon shifting to the north Wednesday night and northwest Thursday. Winds will gust 20-30 MPH Thursday evening.
Blowing/ Drifting: Light to moderate by Thursday evening
Pavement Impacts: Salting and plowing will be required
A busy 48 hours awaits for central Indiana as a winter storm begins to impact the region. Mid and high level cloudiness will continue spreading over the region this evening and give way to a lowering and thickening cloud deck overnight and Wednesday morning. This is all thanks to a developing area of low pressure over the Ark-la-tex region. This surface low will track northeast into the TN Valley Wednesday and into the central Appalachians Wednesday night into Thursday morning. Long time residents of the Hoosier state know this is a favorable track for impactful wintry weather across these parts and this will be no exception.
Moisture will begin to lift northeast during the day Wednesday and reach the I-70 corridor around or just after lunchtime. Across the southern half of Indiana, this moisture should primarily fall in the form of a cold rain (perhaps a bit of sleet initially as the precipitation moves in). However, further north, trouble will ensue. The air won’t only be colder at the surface, but the depth of cold air will be much deeper. This will result in precipitation that should predominantly fall in the form of a sleet-snow “concoction” along and north of the I-70 corridor where we think an axis of 2″ to 4″ of snow/ sleet will accumulate with this storm- including Indianapolis. Further north, less sleet is anticipated and will result in heavier snowfall totals. The northern Indianapolis ‘burbs and points north to include Lafayette, Kokomo, Logansport, Ft. Wayne, and Muncie can expect 4″ to 6″ of snow with this storm system. Most of that will fall Wednesday afternoon into Wednesday night with additional lighter snowfall accumulation occurring with “wrap around” snow showers and embedded squalls Thursday afternoon into evening. (The Indiana Snowbelt (you know who you are :-)) can expect additional heavier snow accumulation, courtesy of lake effect).
A brief, but potent shot of arctic air will pour into the region Thursday afternoon and set us up for widespread single digits by Friday morning, including the threat of some sub-zero temperatures where the heaviest snowpack is laid down.
Confidence: High
Next Update: Wednesday morning

Client Brief: Heavy Snow Bands Return Into The Overnight…
Type: Impactful Wintry Weather
What: Accumulating snow; mixed wintry precipitation
When: This evening into Tuesday morning
Temperatures: Lower to middle 30s, falling into the middle 20s Tuesday morning
Wind: Northeast shifting to the northwest Tuesday morning
Blowing/ Drifting: Minimal
Pavement Impacts: Plowing and salting will be required.
“Round 2″ is underway and we actually believe the overall snow shield will become more expansive with time through the late evening and overnight hours. Within this growing snow shield, embedded banding is expected that will include moderate to heavy snowfall rates. This continues to look like an I-70 special with respect to heaviest totals (7″ to 11″ range for storm totals). On either side of that heaviest snow zone, 4″ to 7” can be expected. On the north side, this is due to lighter intensity of snow (both with Part 1 and Part 2) and mixing issues on the south side.
Snow will exit the city just before daybreak, and southeast Indiana between 8a and 9a. Winds will shift to the northwest and an overall colder day is expected Tuesday, but at least we won’t have to worry about additional snow once past daybreak.
Cold air reinforcements will blow into town Wednesday with a couple snow showers across east-central Indiana. The bigger deal will be the cold, including temperatures that will remain stuck in the middle 20s through the daytime hours. Add in a stiff breeze and wind chill values will be in the 10s.
Confidence: High
Next Update: Tuesday morning

Time For The Heavy Equipment: Localized Storm Totals Approach One Foot By The Time All Is Said And Done…
High resolution guidance started to show the snowier solutions earlier this evening and that trend has continued this evening. The consistency is great to see, but we also notice a couple of interesting elements “upstream” that will likely ultimately end up producing a memorable mid-December snow storm across central Indiana by the time all is said and done.
Before we talk specifics, here’s our updated snowfall forecast. Please note, this is expected total snowfall by daybreak Tuesday morning. We wouldn’t be shocked to hear of localized one foot amounts along the I-70 corridor.
Periods of heavy snow will come to an end during the overnight. We think by 3a to 4a, most of the snow from “round 1″ will be to our east and we’ll be left with clean up duties before a Monday morning rush that will likely still be heavily impacted. By the time the 1st round is finished, most of the I-70 corridor will be shoveling and plowing away 4″ to 6” of wet snow.
We’ll then get into the expected lull in the action through a good chunk of the daytime Monday. That said, curious eyes will be focused in on south-central MO mid-to-late morning as precipitation blossoms in response to a strengthening surface wave that will move northeast out of the Ark-la-tex and into the TN Valley tomorrow night.
This will promote an expanding shield of moderate to heavy precipitation moving northeast and overspreading central Indiana by mid afternoon Monday. For us here across central Indiana, this will fall as snow.
If you don’t have to travel tomorrow, we’d recommend staying home and off the roads. While conditions will improve late morning into early afternoon, travel conditions will go downhill in significant fashion by 3p to 4p Monday across central Indiana- including the metro.
Periods of snow, heavy at times, will continue into the overnight before pushing off to the east before sunrise Tuesday. By that time, the heart of central Indiana will be cleaning up from a double digit and most memorable mid-December snow storm.
We’ll be left with colder, but generally dry conditions Tuesday. Temperatures will remain below freezing through the day, but the majority of the region won’t be dealing with any additional snowfall after sunrise…
Gas up that snowblower! Next update will come early in the AM.
