Client Brief: Thump Of Wet Snow Saturday Night – Sunday Morning…

Type: Impactful wintry weather

What: Accumulating snow

When: 11p Saturday – 11a Sunday

Temperatures: Lower 30s

Wind: E shifting to the NW Sunday morning 5-15 MPH

Blowing/ Drifting: Minimal

Pavement Impacts: Plowing and salting will be required

Summary: A cold core upper level disturbance will lift northeast out of north-central Texas tonight and directly over Indiana Saturday night and Sunday morning. After a dry period of weather through the daytime Saturday, a mix of rain and snow will overspread central IN by late evening. As the upper level disturbance moves overhead, the column of air should become just cold enough to allow the wintry mix to transition to all snow during the overnight. Embedded bands of moderate to heavy snow may develop early Sunday morning. The system will pull east of the state Sunday afternoon, allowing the snow to come to an end by mid to late morning.

Confidence: Medium – high

Next Update: Saturday morning

01.01.21 Weather Bulletin: Prospects Of Accumulating Snow Increasing Tomorrow Night…

Freezing Rain Changes To Rain; Accumulating Snow Tomorrow Night? Low pressure will track into the eastern Great Lakes tonight. Temperatures will slowly rise through the day, allowing freezing rain to transition to rain. Slick roads this morning will slowly improve through the afternoon.

Attention will then shift to a trailing piece of upper level energy Saturday night and Sunday morning. While thermal profiles are marginal at best, the track and strength of the upper level energy will lead to the potential of accumulating wet snow Saturday night and Sunday morning. These are the kind of systems that can manufacture their own cold and result in “surprise” snow events for some. As things stand now, we expect a band of accumulating snow to develop across central Indiana into western Ohio tomorrow night and Sunday morning. We’ll keep a close eye on data the rest of the day and update later this evening.

Weak high pressure will nose into the region as we kick off the new work week, allowing sunshine to return.

Client Brief: Freezing Rain Arrives Pre-Dawn Friday…

Type: Impactful wintry weather

What: Freezing rain/ icy glaze

When: 2a – 1p Friday

Temperatures: 25° to 30° (location dependent, please see below)

Wind: East 5-15 MPH

Blowing/ Drifting: Non-existent

Pavement Impacts: Salting will be required

Summary: After a dry New Year’s Eve, moisture will advance north as a surface low tracks from the northwestern Gulf Coast into the Ohio Valley. As the precipitation arrives (around or just after midnight for far southwestern IN before spreading north, reaching Indianapolis by 4a, and north-central Indiana by 6a), it’ll encounter a shallow layer of cold air entrenched at the surface. Several hours of freezing rain can be expected north of a line from Terre Haute, Bloomington, and Cincinnati Friday morning where temperatures will remain below freezing the longest. South of that line, only a brief period of icing is expected before a transition to a cold rain. Further north, especially along and north of the I-70 corridor, temperatures will fall into the middle to upper 20s tonight and slowly rise into the lower 30s by late morning. All of the state will “warm” above freezing by Friday afternoon with any lingering moisture falling as a plain ole rain. Beforehand, an icy glaze is expected to develop predawn Friday and travel will be difficult in places- especially from central IN and points north. If at all possible, we recommend delaying travel until afternoon as conditions should slowly begin to improve by that point.

Confidence: High

Next Update: This afternoon
