The National Weather Service forecast office in Grand Forks has upgraded the winter storm watch it had previously issued for the northern Red River Valley and northwest Minnesota to a winter storm warning, in effect from 1 a.m. Thursday to 1 a.m. Friday.
Six to 10 inches of heavy, wet snow, heavy enough to snap tree branches or power lines, is possible. Even though the ground is still relatively warm, the NWS states that the snow will be heavy enough to accumulate instead of simply melt on contact.
As the system moves in Wednesday night, the precipitation will be in the form of rain. But as northerly winds bring in the colder air, the precipitation is expected to change to snow. On Thursday, the north winds will pick up more, with gusts in the 30 miles per hour range. It could lead to zero visibility at times.
On average, Crookston doesn't receive it's first measurable snow of an inch or more until Nov. 11.
