Type: Impactful Winter Weather

What: Accumulating snow; mixed wintry precipitation

When: Sunday evening through Monday

Temperatures: Lower to middle 30s

Wind: East 10 to 15 MPH, shifting to the north Monday night with gusts to 25 MPH

Blowing/ Drifting: Minimal

We continue to closely monitor the potential of an impactful winter weather maker Sunday evening through Monday. Initially, we think “overrunning” precipitation will overspread central Indiana Sunday afternoon and evening. This should fall in the form of snow for most. As the surface low draws closer, precipitation will increase in intensity Sunday night into the day Monday. The all-important track of the surface low appears to take a path from western Arkansas Sunday night, along the Ohio River Monday morning and into western Pennsylvania by Monday night. This is a favorable track for accumulating snow across portions of the state. The map above features our “ridiculously” early idea on best chances where the heavier snowfall will occur (shoveable totals seem like a good bet for places in and around Indianapolis and points north). Downstate, enough warmer air should get pulled into the system for a time Sunday night into Monday morning that a wintry mix of precipitation (sleet, snow, and rain) is expected to cut down snowfall totals. As the storm pulls up to our northeast, gusty northerly winds will develop with lingering snow showers in Monday night, along with colder conditions.

We’ll have an updated video post later this evening and will keep close eyes on data not only today, but straight through the weekend.

Confidence: Medium-High
