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.

02.12.21 Weather Bulletin: Continuing To Keep Close Eyes On Next Week…

Updated: 02.12.21 @ 7:34a

Use This Weekend To Prep…The short-term portion of this forecast is relatively quiet. Take advantage and prepare for significant winter weather next week. We may even see a few breaks in the cloud cover today. All in all, look for mostly cloudy and continued cold conditions. Keep in mind, average highs this time of year should be close to 40°. We’ll be nowhere near that anytime soon. In fact, most days will feature high temperatures even colder than average lows for this time of year!

Reinforcing arctic air will penetrate the area Saturday and will likely kick up some light snow showers- especially during the afternoon. Light snow will remain a possibility Valentine’s Day, but “light” is the key word.

The more exciting part of this forecast comes at us as we open the work week. Surface low pressure will develop in the northwest Gulf of Mexico Sunday night and track northeast up along the Appalachians. This will spread a swath of snow into the Ohio Valley through the day Monday. It appears as if snow will become heavy at times Monday evening into the predawn hours Tuesday before tapering to light snow/ snow showers late Tuesday morning. This will be a much more powdery snow than we typically see with these Gulf storms, due to having truly arctic air involved with the storm. Gusty winds will create significant blowing and drifting issues throughout the early and middle portion of the work week.

That then leads us to the threat of another significant winter storm as we push into Wednesday night into Friday morning. We don’t want to get ahead of ourselves, but the threat is very real that this storm also deals out heavy impacts across the region with additional heavy snow possible during the aforementioned time frame.

We’d suggest using the weekend to prepare for the potential of two back-to-back “big deal” winter storms. We’ll be here through the weekend with additional updates.

Averages: H: 39/ L: 23° on the 12th –> H: 41°/ L: 25° on the 18th

Client Brief: Heavy Snow Hit On Deck For The Northern Half Of Indiana…

Updated 01.30.21 @ 7:28a


Type: Impactful Wintry Weather

What: Accumulating snow

When: 4p Saturday – 4a Sunday

Temperatures: 29° to 33°

Wind: SE 10 – 20 MPH and gusty

Blowing/ Drifting: Minimal 

Pavement Impacts: Plowing and salting will be required

Summary: Clouds will continue to lower and thicken through the morning. By early afternoon, the sky across most of central IN will have that classic look of a snowstorm brewing, and rightfully so. The initial band of snow will arrive mid to late afternoon (we bracket 4p to 5p into Indianapolis, itself). The combination of evaporative cooling, strong lift, and embedded banding features will likely result in S+ (heavy snow) throughout the evening hours across central Indiana. This will be a wet, heavy snow. As the heavy precipitation begins, the column of air will cool rapidly late afternoon (temperatures will likely fall from around 40° into the lower 30s within less than an hr as part of the “evaporative cooling” process). Looking over the latest guidance, it continues to appear as if areas along and south of the I-70 corridor will then go just above freezing later tonight and result in a brief mix before transitioning over to rain. Drizzle or mixed rain and snow showers Sunday will transition back to snow showers throughout the afternoon, but the majority of accumulating snow across our region will fall in that 12 hour period from 4p Saturday to 4a Sunday. 

Confidence: High

Next Update: This afternoon (video)
