Client Brief: Another Round Of Accumulating Snow On Deck; Blowing & Drifting Also To Be Dealt With…
Updated 02.09.21 @ 7:15p
Type: Impactful Wintry Weather
What: Accumulating snow
When: Late Wednesday morning through Thursday afternoon
Temperatures: 18° to 24°
Wind: NE 10 – 20 MPH and gusty
Blowing/ Drifting: Considerable
Pavement Impacts: Plowing and salting will be required
Summary: Wednesday will dawn with quiet conditions in place but snow will arrive into central Indiana by late morning. Initially, we’re only talking about light snow into the afternoon and evening. Snow will become more widespread and heavier throughout the “heart” of central IN during the overnight hours and Thursday morning before eventually giving way to lighter snow Thursday afternoon, eventually ending from west to east. Downstate, a mix of freezing rain, sleet, and brief snow is expected, including icy travel. Once again, this will be an efficient snow producer. Instead of snow ratios of 10:1 we expect closer to 15 to 20:1 ratios (similar to that of what southern parts of the state experienced Monday). The dry, powdery nature of the snow will combine with gusty northeast winds to create blowing and drifting issues by Wednesday evening through Thursday, especially in the open country. Gusty winds will persist Thursday night even as the snow comes to an end, extending the blowing and drifting concerns.
Confidence: High
Next Update: Wednesday morning (video)

02.03.21 Weather Bulletin: Keeping A Watchful Eye On The Weekend…
Updated 02.03.21 @ 8:19a
Best Day Of The Week…We can’t get too picky this time of year in the weather department. Long time fellow Hoosiers know to never take a day featuring sunshine for granted in early February. Though still chilly, given the pattern ahead, I’d recommend getting outside and enjoying some of those rays today.
A cold front blows into town Thursday and will deliver a chilly rain by the afternoon. As colder air rushes in on the backside of the system, rain will likely mix with and end as a period of snow across the northern half of the state Thursday evening. Though the moisture will be leaving as the cold air is arriving, we may still be able to squeeze out a dusting to 1″ of wet snow for northern areas.
Attention will then shift to an arctic wave that will move into the Ohio Valley this weekend. Snow will become widespread across the central Plains Friday evening into Saturday morning before expanding east into our neck of the woods Saturday afternoon into Sunday morning. With cold air in place, this will be a higher ratio snow event than we’ve seen so far this winter (“fluff factor” will be in full effect). Additionally, strong and gusty winds are expected during this time frame leading to blowing and drifting concerns. Stay tuned. We’ll take a stab at early accumulation numbers with this evening’s Client Video update.
Additional upper level energy will scoot through the region into early next week, keeping a supply of snow showers ongoing. While still cold, models have pushed back the truly dangerous cold until late week. Case of delayed, but not denied? Unfortunately think so…

Never Trust An Arctic Wave: Accumulating Snow Prospects Growing This Weekend…
Updated: 02.02.21 @ 6:15p
While we have a few flurries (thanks to a little help from Lake Michigan) flying this evening, the bulk of the upcoming 48 hours will be rather quiet across the region. The next item on the agenda will come in the form of a cold front Thursday afternoon. As of now we anticipate rain (perhaps a brief early mix, but this won’t be a big deal) to arrive into central Indiana between 11a-1p Thursday. Mostly light to, at times, moderate rain will continue into the evening hours before ending as a brief period of wet snow Thursday evening (again, little if any impacts are expected).
Rainfall totals between 0.25″ and 0.50″ can be expected Thursday PM with the passage of the cold front.
The relatively quiet regime should return Friday, but by this time all eyes will be focused on the 1st of (2) arctic frontal systems. The 1st of these arctic fronts will sweep through the state Saturday PM and early Sunday. As this takes place, an arctic wave is expected to form along the leading edge of the true arctic air Saturday evening. This should result in an expanding area of snow that originally develops in the central Plains Friday night/ Saturday morning before pushing east, northeast Saturday into Sunday. With the arctic air pouring into the region, this should be a high ratio type snow and blowing/ drifting issues will likely be more of a problem than with the majority of systems so far this season.
While this is all taking place, a secondary low pressure system should develop along the Carolina coast early Sunday morning and it’s this system that will likely become the primary “player on the field” late in the weekend or early next week. Before that though, the arctic wave will likely result in a stripe of accumulating snow from the central Plains into the Ohio Valley, including central Indiana (too early for specific amounts). This will lay the groundwork for the coldest air of the season early next week…
Snow removal clients, as well as those in the ag. industry should keep close tabs on the weekend forecast. While we’re not expecting a widespread heavy snow event, the combination of snow, wind, and eventual bitterly cold air will lead to significant impacts as we move forward.
I would plan on temperatures falling into the single digits below zero, along with wind chill values potentially approaching 20° below zero by early next week.
Stay tuned.
