A potent storm system is expected to quickly move into our region Tuesday and possibly make headlines by producing the first shovelable snowfall in our viewing area by Wednesday morning. A Winter Storm Watch has been posted for the counties north and northwest of Rochester and west of Albert Lea where early season snowfall may warrant the use of a shovel, and in some cases, a snow plow. The biggest concern right now appears to be the morning commute Wednesday with the potential of a fresh coating of a couple of inches of snow on the ground, possibly working to slow things down and make surfaces rather slippery. Right now it looks like the watch will turn into an advisory when the snowfall looks more imminent as totals will be less than the six-inch threshold that would be cause for the issuance of a Winter Storm Warning. Locally, totals will be an inch or two in our north and northwest counties with the outside chances of seeing a few three-inch totals in some spots. The Twin Cities look to receive three or four inches of snow by early Wednesday while Rochester, which is outside the Winter Storm Watch, will likely end up with less than half an inch of grassy accumulation ending sometime before the mid morning.
