Client Brief: Snow Builds In Overnight – Predawn Thursday…

Updated: 02.17.21 @ 4:54p

Type: Impactful Wintry Weather

What: Accumulating snow

When: 2a to 9p Thursday

Temperatures: 18° to 24°

Wind: N 10-20 MPH, shifting to the NW Thursday night

Blowing/ Drifting: Considerable  

Pavement Impacts: Plowing and salting will be required

Summary: Another round of snow will lift northeast into central Indiana during the overnight and predawn hours (likely arrives into Indianapolis between 1a and 2a). As like so many of these events in the past, this will be another cold storm, meaning we’re looking at another high ratio (15-20:1) event. The dry, powdery nature of the snow will be blown and drifted around by north to northwest winds of 10-20 MPH through the day. While heaviest snow bands should remain across southern and southeastern Indiana, I still expect the rather persistent nature of the snow tomorrow to add up to the tune of 1″ to 3″ for Indianapolis and surrounding areas. Travel will be impacted, including both the morning and evening rush hour. Eventually the snow will depart from southwest to northeast after dark, exiting Indianapolis by around 8p to 9p.

Skies will slowly clear up on Friday and lead to a dangerously cold night (similar to what we saw this morning) and Saturday morning.

Confidence: High

Next Update: Thursday morning

02.17.21 Weather Bulletin: Snow Returns; Keeping An Eye On Sunday…

Updated 02.17.21 @ 8:06a

Snow Builds Back In…As easy as the previous storm was, this one has been a royal pain in the neck. Stubbornly, I anticipated a further northwest shift (especially given the PNA state), but that’s not to be the case. While southern and southeastern Indiana will tack on a few additional inches with this storm, this is a 1″ to 2″ type deal for central Indiana, and most of that falls tomorrow morning into Thursday afternoon.

A few lingering light snow showers are possible Friday followed by clearing. High pressure will build overhead Friday night and set us up for another “nasty” cold night. Temperatures will likely rival where we are this morning come Saturday morning as winds go calm and skies clear.

The next potential trouble maker looms on the horizon Sunday. Models are beginning to slowly understand that we’re simply not going to dislodge all of this cold air in quick fashion. As such, a wintry mix and/ or wet snow is becoming increasingly likely by Sunday PM into Sunday night as this system blows through.

Quiet conditions return into early portions of the work week.

Averages: H: 41°/ L: 24° on the 17th –> H: 43°/ L: 26° on the 23rd
