A complex storm system bearing down on the region for the weekend is expected to come in waves and bring a variety of precipitation.
The National Weather Service forecast office in Grand Forks has issued winter storm storm watch, which is in effect from Friday evening through late Saturday night. The further east and northeast you go, the more snow is expected to fall.
Crookston is on the southeastern edge of the watch box. As the system moves in and its track becomes even more defined, it's likely that the winter storm watch will either be upgraded to a warning or downgraded to something like a winter weather advisory.
Precipitation for the area is expected to start with a a mix of rain, freezing rain and sleet late Friday and continue through much of Saturday, before changing over to snow. Depending on precisely when the precipitation changes to snow, up to 4 inches could be possible by Sunday in and around Crookston, with road conditions becoming slippery because of any freezing precipitation that may have fallen early on. The potential will be there for 1/4 inch of freezing precipitation before the snow commences, and several inches of slush and sleet.
Winds are expected to be east to northeast at 15 to 25 mph Friday night into Saturday morning and will become north at 15 to 30 mph with higher gusts that will lead to falling temperatures.
Anyone traveling west this weekend, be aware that conditions could be worse as heavy snow, possibly up to 12 inches, will fall in a line from along and north of Devils Lake into extreme northern Minnesota. Winter storm warnings are already in effect for western North Dakota into the Devils Lake region, and a blizzard warning has been issued for eastern Montana, where accumulations could be up to 18 inches.
