Special Weather Statement issued February 1 at 6:17PM CST by NWS Quad Cities IA IL

Effective: Sun February 1, 2026, 6:17 PM
Expires: Mon February 2, 2026, 12:00 AM

As snow moves east through the area, it will transition to freezing drizzle. The freezing drizzle will gradually come to an end later this evening. The impact of the freezing drizzle and any ice glazing will be greatest for roads that are not covered in snow already or have treatments down for melting. Be careful if moving about this this evening as conditions may be more slippery due to the combination of snow and freezing drizzle.

At 445 PM...radar indicated that the snow would be ending along the Mississippi river between 5 and 6 pm. In southeast Minnesota and northeast Iowa where the snow has ended, freezing drizzle has been reported, heaviest in Minnesota. This has caused a slight increase in accidents, according to law enforcement, in southeast Minnesota. In Wisconsin, as the snow comes to an end over the next hours, expect the same period of freezing drizzle to occur, causing slick roads to persist. The freezing drizzle will gradually come to an end this evening. The impact of the freezing drizzle and any ice glazing will be greatest for roads that are not covered in snow already or have treatments down for melting. Also, the drizzle will be more steady in southeast Minnesota into west-central Wisconsin. Be careful if moving about this this evening as conditions may be more slippery due to the combination of snow and freezing drizzle.

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.
