Rain-To-Snow Switch Tuesday Could Snarl Twin Cities Commutes: MN Weather

MINNEAPOLIS, MN — A storm system will bring rain, snow, and strong winds to Minnesota beginning Tuesday, according to the National Weather Service.

Forecasters predict that rain will arrive early Tuesday, transitioning to snow by late afternoon and evening as colder air moves in.

A Winter Storm Watch is in effect for much of central Minnesota, including areas north of Morris and Mora, where the highest potential exists for several inches of accumulation. The NWS says snow rates could exceed half an inch per hour at times, creating quick travel impacts.

The heaviest totals remain focused from Douglas County through Morrison, Mille Lacs, Kanabec, Stearns, and Todd counties.

The official forecast shows three to seven inches possible near Alexandria, with Brainerd and Fergus Falls in the three to eight inch range.

Farther south, totals drop off sharply, with one to three inches possible around the Twin Cities and lighter accumulations toward Mankato, Rochester, and Marshall.

Forecasters also warn that strong northwest winds, gusting between 35 and 40 mph, may produce blowing snow and reduced visibility late Tuesday into Wednesday. Roads may become slick, and both the Tuesday evening and Wednesday morning commutes could be affected.

Probabilistic forecasts reinforce the north–south split. Brainerd has a 91 percent chance of at least two inches and a 73 percent chance of four inches. Alexandria has a 79 percent chance of two inches and a 61 percent chance of four inches.

The Twin Cities has a 34 percent chance of two inches and only an 8 percent chance of four inches.

Locations south of Interstate 90 have very low probabilities of meaningful accumulation.
