Below is a map of snowfall that occurred across the region March 11-12, 2018.

It should be noted that the highest snowfall report received was 10", but the range goes up to 12" on the legend. Please keep in mind that snowfall was hit or miss in some spots and this is and interpolated map. It could be slightly off in your area. You'll also find a second map that shows snow depth observed at 7 AM. Some snow was lost to compaction and melting by this time, and it may differ slightly from the snowfall totals.
