The winter storm watch issued by the National Weather Service Friday, has now been upgraded to a warning for Richfield and much of the metro area.

The warning is in effect from midnight Sunday through 6 a.m. Monday for most of the Twin Cities region, as the storm now being called "Orko" sweeps across Minnesota.

Snow accumulations of four to eight inches are possible in locations across Hennepin, Anoka, Ramsey and Washington counties, as well as western Wisconsin, with accumulations increasing from south to north.

A wintry mix of snow, freezing rain and sleet should start falling late Saturday night, transitioning to a mix of rain and snow during Sunday, then switching to heavy snow at some point Sunday afternoon. Strong winds on Sunday night will blow the snow around, creating hazardous travel conditions.

Because temperatures on Sunday will hover right around the freezing point, the National Weather Service says “there is still uncertainty” about just how much snow may stick. What is certain right now: Monday morning’s commute is likely to be a sloppy mess.

Richfield Patch will update readers if new information on the storm becomes available.
