It’s been a messy Saturday in parts of the Midwest as an area of low pressure tracks east-northeast across Missouri.
Warmer air and moisture surging north ahead of this system caused some snow and freezing rain/drizzle in parts of the Upper Midwest today, with the most significant ice accumulations reported in parts of Iowa, where we’ve seen anywhere from 0.20 inches to 0.40 inches of ice accumulation.
The precipitation that occurred in parts of the Northland today has been on the light side, but there’s been enough snow to cause some slippery road conditions. Note: 0.2 inches of snow so far today in Duluth (NWS location).
Also of note, we’ve seen a few severe thunderstorms develop late this afternoon over central Missouri, with a risk of large hail and damaging wind gusts.
