Special Weather Statement issued January 17 at 9:31AM CST by NWS Quad Cities IA IL

Effective: Sat January 17, 2026, 9:31 AM
Expires: Sat January 17, 2026, 6:00 PM

A band of light snow will continue to move southward today through the afternoon hours, with total snow accumulations of 1 to 2 inches possible for areas along and north of Highway 30. Northwesterly winds, gusting around 25 to 35 mph, will result in blowing snow, with reduced visibilities of a mile. Lower visibilities are possible in open, rural areas. Additionally, pavement temperatures in the teens should allow some partially snow-covered roads with slick spots. If planning to travel this morning through the afternoon hours, be ready for sharply reduced visibilities in blowing snow. Take it slow on the roadways, and allow plenty of following distance between you and the vehicle in front of you.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
