High Impact Winter Storm This Weekend

A high impact winter storm is expected Saturday night through Monday morning which could bring heavy snow, freezing rain, and blizzard conditions. Monitor the forecast for the latest updates and make appropriate preparations! Read More >

A high impact winter storm will bring snow and a wintry mix of rain, freezing rain, and sleet this evening and continuing into Monday morning. Confidence is high that there will be a band of heavy snow somewhere north of I-90, but exactly where this band sets up is still somewhat uncertain. There will also be a sharp cutoff in snow amounts on the south side of this band where that wintry mix occurs instead of snow this evening to early Sunday afternoon. Regardless of snow amounts, strong winds on the backside of the storm Sunday afternoon into Monday morning will likely lead to blizzard conditions in open areas. Monitor the latest forecast for updates as the track of the storm is better pinned down. Expect difficult to impossible travel conditions where the heavy snow band and icing ultimately occur.
Trends are now favoring a wintry mix of rain, freezing rain, and sleet to lifting north toward the Interstate 90 corridor as the winter storm gets underway this evening through early Sunday afternoon. Sleet and freezing rain are likely (60-80% chance) during this timeframe before precipitation eventually changes over to just snow for Sunday evening into Monday. Up to 1/4 inch of ice is expected.
Here is a rough timeframe of expected timing of various precipitation types and intensities for this weekend's winter storm.
With a major winter storm starting this evening, wrap up preparations today. Check your food, gas, and other emergency supplies and be prepared for poor to impossible travel conditions Sunday into Monday morning.
