SIOUX CITY | Snowfall before Halloween doesn't happen every year in Siouxland, but some snow was spitting out of squalls in the Sioux City metro and east of the city along U.S. Highway 20 early Friday.

The snow lasted only in short bursts, and none had accumulated in Sioux City by 7 a.m.

The National Weather Service in Sioux Falls set a forecast for Sioux City with a slight chance of snow before noon, then a chance of flurries between noon and  2 p.m. Friday.

The Sioux County (Iowa) Sheriff's Office in a Facebook post at 6:45 a.m. reported that "due to weather, road conditions for Sioux Co. are becoming slick, especially around Highway 60 area."

On Thursday afternoon, the weather service issued a Winter Weather Advisory for Osceola, Dickinson, Clay and Emmet counties in Iowa into late Friday. By Friday morning, that had been dropped, although there is a Wind Advisory for all tri-state Siouxland counties Friday to 7 p.m.

The forecast is for winds of 30-40 mph, with gusts to 45. That makes for two windy days in a row, as winds buffeted the region Thursday.

The forecast high temperature for Friday in Sioux City is 39 degrees.

The compilation of historic data shows Sioux City on average gets 0.7 inches of snow in the month of October.
