It’s shaping up to be a frightful forecast for Halloween across much of Minnesota as rain is likely to change over to snow — possibly heavy at times — from the Twin Cities north to Duluth.

The transition from rain to snow was underway before sunrise in southwest Minnesota, where Minnesota Department of Transportation traffic cameras showed some accumulation on grassy areas. Roads appeared to be mainly wet, as pavement temperatures remain above freezing.

The changeover will spread north and east. Winter weather advisories go into effect Thursday morning from McLeod, Sibley and Le Sueur counties northeast through most of the Twin Cities metro area and along the Interstate 35 corridor to Pine City, Cloquet and the Twin Ports. Those advisories run through the afternoon.

The National Weather Service said the advisory areas could see 2 to 4 inches of snow with locally higher amounts.

Snowfall rates of 1 inch per hour are possible in some areas. A few embedded thunderstorms are also possible, which could “enhance snow rates further,” the weather service said.

Northwest Wisconsin is also under a winter weather advisory from Thursday morning through Thursday evening.

The rain and snow will be accompanied by gusty winds and falling temperatures. The precipitation is expected to largely end before trick-or-treaters head out Thursday evening.
