Timing hasn’t changed much over the past 18-24 hours. We’re still looking at the heaviest snowfall from 10 p.m. until 4 a.m. Thursday morning. Snowfall amounts over this 5-6 hour window could range from 4-6″. Light snow will linger throughout the day on Thursday which could inflate some totals across the area. Expect slow travel Thursday morning with snow-covered roads.

I have made some minor changes to the snowfall forecast here locally. Generally, most of the area will be in the 4-8″ range with some areas in the lighter and some on the higher end of that range. Current guidance is suggesting some areas west of Hwy-52 are on the lighter end of that 4-8″ range.
