Client Brief: Blizzard Conditions Develop Friday Into Christmas Eve…

Updated 12.19.22 @ 5:46p

Type: Severe Winter Weather

What: Heavy snow, blizzard conditions, dangerously cold temperatures

When: Thursday PM through Saturday

Temperatures: Falling from the lower 40s (Thursday afternoon) to 0° to 10° below zero (Friday morning).

Wind: WSW 15-25 MPH, increasing to 25-40 MPH with gusts to 55-60 MPH

Blowing/ Drifting: Severe

Pavement Impacts: Plowing and salting will be required throughout the region.

Summary: Normally, we wait another 24 hours closer to the onset of the storm before we initiate our official Client Briefs, but the combination of the intensity of this storm along with the timeframe when many folks will have travel plans, we wanted to get this product out earlier than normal. We strongly encourage having travel completed by Thursday evening.

In short, a severe winter storm continues to look like it’ll take aim on the region as we navigate the day Thursday. Rain is expected to develop during the day before mixing with and transitioning to snow Thursday night. Snow will become heavy at times Thursday night into the day Friday. Initially, this will be a heavy, wet snow, but as the arctic airmass engulfs the area, the “paste-like” snow will quickly transition to powder. Needless to say, the standard 10:1 measurements won’t work with this storm as the fluff factor kicks into high gear.

Unfortunately as this transition in snow type is taking place, winds will begin to increase. We anticipate major problems from severe blowing and drifting of snow by Friday, continuing through Christmas Eve. During the aforementioned time period, wind gusts in excess of 55 MPH will be possible. This will lead to impassable roadways across many areas, especially within the heavier snow zones below. Speaking of snow, we need another 24 – 36 hours before we can get more specific than included below. Areas across southern and eastern IN not currently within the “heavy snow zones” will still see several inches of accumulation and their own blowing/ drifting issues. Blizzard conditions can be expected across the entire area from a combination of the falling snow, snow already on the ground, and damaging wind gusts Friday into Christmas Eve. Drifts will be measured in feet, especially in the “open country.”

I’d like to encourage everyone to prepare for the bitterly cold airmass that will also grab headlines. Be thinking of ways to keep warm should you lose power. Unfortunately, with the expected wind, power outages will become an issue across the region. Please take the time now to inspect your winter storm safety kit and heed all products from the National Weather Service.

Confidence: High

Next Update: Tuesday morning (video discussion)

Light Snow Showers Today; Pre-Christmas Winter Storm Precedes Dangerous Cold Next Weekend…

Updated 12.17.22 @ 7:11a

Just enough upper level energy will linger around the region to help generate occasional snow flurries or light snow showers into Sunday morning. Like the past 24 hours, these won’t amount to much if any accumulation.

High pressure will then dominate our weather through the early and middle part of the work week with dry and seasonably cold conditions.

By this point, all eyes will be on the developing winter storm in the Plains. We expect snow to overspread the region Thursday (possibly beginning as a brief period of rain), continuing, potentially heavy at times, through the day on Friday. This still has the potential to be a significant, if not severe, winter storm but we’re still a couple days away from being able to talk specifics in respect to snowfall totals. Another item to note will be the wind. Blowing and drifting will likely be a major problem by Friday, into Christmas Eve. If there’s anyway to move travel to Wednesday, we’d highly recommend it.

A nasty shot of bitterly cold arctic air will plunge into the region Christmas weekend. How do highs in the 0s to low 10s sound and overnight lows below 0°? Wind chill values of 20° to 40° below zero (not a typo, unfortunately) are on the table.

VIDEO: It’s Show Time…

Updated 02.02.22 @ 8:47p

After reviewing the latest data, we have no reason to adjust our ongoing ideas from our latest Client Brief or this morning’s video discussion. Thursday will feature a prolonged period of heavy snow into the evening hours, along with an increasingly stiff NNE wind that will lead to significant blowing and drifting issues- especially during the afternoon and evening. Much more in the AM, friends!

No changes are needed to our ongoing snowfall forecast.

Client Brief: All Systems Go For Highly Impactful Winter Storm…

Updated 02.01.22 @ 7p

Type: Severe Winter Weather

Heavy snow will fall across central IN Thursday

What: Heavy mixed precipitation, heavy snow, & strong winds

When: Wednesday afternoon through predawn Friday

Temperatures: Mid 30s, falling into the upper 10s Thursday night

Wind: NNE 15 – 25 MPH (gusts up to 30 MPH Thursday)

Blowing/ Drifting: Significant to severe (especially on east-west roadways)

Pavement Impacts: Plowing and salting will be required

Summary: While we don’t have any significant changes to this morning’s video update, we continue to draw that much closer to “show time” with this winter storm. Conditions will deteriorate from northwest to southeast as we progress through the day tomorrow, but the “main show” for immediate central IN will come late tomorrow night and through the day Thursday. It’s during this time where snowfall rates will exceed 1″/ hour for a widespread portion of the region. Simply put, if you don’t have to travel, please don’t. The added concern also remains present of blowing and drifting issues that will likely develop during the day Thursday. This will be from a byproduct of an increasingly fluffy snow (anything that falls tomorrow will be of the wet, slushy nature), thanks to higher ratios, as the arctic air pours into the region. Add in a stiff north, northeast wind of 15-25 MPH with gusts to 30 MPH and you can easily see where the problems are likely to ensue. In particular, east-west roadways in the open country are likely to drift shut by late morning or afternoon Thursday. Snowfall coverage and intensity will finally begin to diminish from northwest to southeast Thursday night. By that point, it’ll be time to bring the heavy equipment out to engage in removal of the “BIG SNOW.” We still anticipate bitterly cold (5° to 15° below zero) temperatures to take up shop Saturday morning across the region.

Confidence: High

Next Update: 7a Wednesday
