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

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.
