Type: Impactful Winter Weather

What: Accumulating wet snow

When: This afternoon into early evening 

Temperatures: Falling from the upper 30s early afternoon to around 30° by late evening.

Wind: North 20-25 MPH

Blowing/ Drifting: Non-existent to minimal

Pavement Impacts: Salting required. Plowing will also likely be needed across east-central Indiana.

There’s an old saying in the weather business of an “upper low being a weatherman’s foe.” That’s particularly true early and late in the season due to the added complexities of marginally cold air typically available. As we discussed over the past week, the dynamics and cold air these type of systems can manufacture also creates added headache. Many instances these kind of systems result in essentially a “now cast” scenario. With all of that said, our confidence is increasing after another look at overnight model runs to put out the snowfall forecast above. Rain will overspread central Indiana late morning into the early afternoon, however, as the precipitation rates increase, we’ll notice a transition to wet snow this afternoon into the evening. There could also be a brief wintry mix, including sleet, during the transition to wet snow. Banding features will likely develop late afternoon into early evening leading to heavier snowfall across east-central parts of the state where we have the 1″ to 3″ snowfall forecast up. For the remainder of central Indiana, most should be closer to a coating with a few 1″ reports. The snow will exit even far eastern areas before midnight.

Confidence: Medium

Next Update: This afternoon
