A Messy Saturday Across The Region
Forecast loop from 6 PM Friday to 6 AM Sunday.
We continue to watch a very messy Spring storm moving in as we head through Friday Night into Saturday. We'll watch two waves of moisture. The first move in Friday Night, bringing some freezing rain and rain along with it. Some precipitation will remain as we head into Saturday morning, but many areas might actually get a break for a little bit. The second batch starts to move in during the late morning hours, bringing showers and storms from the metro southeastward and freezing rain/snow to the northwest. As we head into Saturday Night, rain here in the metro will change over to freezing rain, then snow, ending as we head toward Sunday morning.
Overall liquid amounts (rain or melted wintry precipitation) will be around or over an inch from parts of eastern Minnesota into Wisconsin.
Mainly off to the northwest of the metro - from areas like Canby to Little Falls to the North Shore - have the best chance of seeing a band of at least 2-5" of snow. We will also watch the icing potential across the region, with over a tenth of an inch possible in these same areas.
Across the region with this storm we have Winter Weather Advisories stretching from southwest Minnesota to the Arrowhead, Winter Storm Warnings around Duluth due to heavier snow and ice accumulations, and Ice Storm Warnings in Wisconsin and the U.P. of Michigan due to the potential of a quarter-inch or more of ice.
In the warm sector, we will also be watching the potential for severe weather. A Slight Risk of severe weather now nudges north into southeastern Minnesota on Saturday, including the Rochester area. Large hail, damaging winds, and a few tornadoes are possible. Note the earliest tornadoes on record for the state came on March 6th, 2017.
Again here in the metro, we will mainly be tracking rain during the daytime hours and even the potential of a few storms. Rain is expected to be light to moderate throughout the day. Highs will climb into the mid-40s.
Storm chances will continue through the evening hours before we start to see it change over with the dropping temperatures to a mix and eventually snow. Precipitation should mostly be done by daybreak Sunday, but I don't think I can rule out a flurry or two still around Sunday morning.
