Client Brief: Snow Builds In Overnight; Becomes Heavy Monday Afternoon Into Monday Night…

Updated 02.14.21 @ 12:29p

Type: Severe Wintry Weather

What: Heavy snow & strong winds

When: Monday morning – Tuesday morning

Temperatures: 16° to 21°

Wind: NE 15 – 25 MPH (gusts up to 35 MPH Monday evening)

Blowing/ Drifting: Severe  

Pavement Impacts: Plowing and salting will be required

Summary: Light snow will overspread central Indiana during the overnight, continuing through Monday morning. As the surface low moves northeast (up the Appalachian chain), snowfall rates will increase Monday afternoon into Monday night, becoming heavy at times. The cold nature of this storm system will lead to an efficient snow producer, including rates that will likely top 1″ per hour at times Monday afternoon into Monday evening. As the low moves closer, the pressure gradient will tighten and lead to strengthening northeast wind gusts (up to 35 MPH) for a period of time after sunset into the late evening hours. Travel is highly discouraged tomorrow, especially by afternoon and evening as the combination of heavy snow and strong winds will likely lead to some roadways becoming impassable. Drifts in the open country will likely reach 3 to 4 feet by Tuesday morning. Snow will end from southwest to northeast Tuesday morning.

*Our other products issued later tonight will handle the expected additional significant impacts with Storm #2.

Confidence: High

Next Update: Tonight (video)

02.14.21 Weather Bulletin: Memorable Week Of Winter Weather…

Updated 02.14.21 @ 8a

Back-to-Back Heavy Snow Storms…Use today to complete preparations for what will be a memorable week of winter weather. While bitter out this morning, we’ll at least enjoy a dry day. Wind chills that are at dangerous levels right now (-10° to -20°) will “warm” to between 0° and 5° above this afternoon.

Snow will overspread the state from southwest to northeast as we move through the night. Initially, we’re talking about mostly light snow, but roadways will be a mess for the morning commute Monday (given how cold it’s been as of late). If you can avoid travel altogether, we’d recommend doing so. Snow will really begin to pick up in intensity after lunchtime Monday, and especially towards evening, continuing into the overnight hours. Periods of heavy snow can be expected during this time frame. The snow will be mostly out of here by Tuesday morning, but not before depositing a widespread 5″ to 8″, including localized amounts up to 10″. You’ll want to get on the clean up from the first storm as another “big one” awaits.

After a mostly dry Tuesday and daytime Wednesday, light snow will develop towards sunset and become heavy at times Thursday. This second storm has the potential to be equally, if not more, significant than its predecessor and we’ll have early snowfall numbers issued this afternoon. By Friday morning, widespread snowfall totals of 10″ to 15″ (if not more in spots) can be expected with drifts in the open country that even a yardstick won’t be able to handle.

We’ll have our updated snowfall maps included with our Client video update that will be published this afternoon. A Client Brief will be posted later today, as well, focusing on the specific details of Storm #1.

02.13.21 Weather Bulletin: Snowfall Forecast Issued; Initial HVY Snow Zone Idea For Midweek…

Updated 02.13.21 @ 9:56a

Back-to-Back Winter Storms…A weak trough of low pressure extends south into the northern portion of Indiana this morning. This will serve to help enhance snow “up north” through the day- including a little lake enhancement this evening. Scattered snow showers will work into central Indiana later this afternoon into the evening, but shouldn’t be a big deal.

Bitterly cold air will greet us out the door Sunday morning, but this will be the proverbial calm before the storm. A mix of clouds and sun will give way to an increasingly cloudy sky during the evening hours and snow will break out from southwest to northeast late Sunday evening into the overnight and predawn Monday. This is the “1st wave” of the early week storm. A lull in the snow is possible late Monday morning into the early afternoon before the real show begins Monday evening into the predawn hours Tuesday across southeast Indiana. This will be a very cold storm and snowfall ratios will be much higher than standard 10:1 (closer to 15-20:1) which means this should be an efficient snow producer across the region. The dry, powdery nature of the snow will blow about quite easily and snow removal clients should prepare for an extended period of significant blowing and drifting issues through the upcoming week (even well after the falling snow stops).

Here’s our first stab at accumulation with Storm #1. We’ll refine these numbers if need be moving forward.

Morning snow will end from west to east Tuesday morning and we’ll have about 24 hours of relative calm before additional fun and games roll into town Wednesday night. While still early, there seems to be potential for Storm #2 to be more significant across a larger chunk of the state. We’re noticing the majority of forecast models starting to “bulk up” on precipitation amounts with this storm and the negative PNA will likely continue to force the storm ever so much further west with time. The potential is even present for more mixing issues as warmer air aloft is drawn in across southeast Indiana. Where things remain mostly (if not all) snow, a big hit is likely Wednesday evening into Friday morning. Let’s get through the day tomorrow before getting specific with totals, but here’s our initial idea.
