QUAD CITIES, IA/IL- ***FIRST ALERT DAY THROUGH 6AM FRIDAY***

A First Alert Day is in effect for blowing snow and windy conditions. Rain has almost changed over to snow for most of the QCA at this point. The arctic front will arrive over the next few hours and this will cause flash freezing of any standing water and create easier blowing and drifting snow potential. Snowfall amounts have skewed a tiny bit higher, but aren’t the biggest impact from this system. In general, 2″-5″ will be seen along and north of I-80 and 1″-2″ south of I-80, the problem will be the long duration of near white out conditions as winds gust close to 40mph from the NNW.Snow will stop falling by 6PM, but ground blizzard conditions will last until early Friday morning, especially in open and rural areas. Temps will drop to the single digits tonight and arctic air will settle for a long duration. Over the weekend we will have a series of clippers bringing light snow chances to the region along with reinforcing shots of cold air. Many of us will be below zero each morning next week and wind chills may be as cold as -25º.

TODAY: Windy with rain changing to snow. High: 36º Wind: NW 15-25 mph.

TONIGHT: Blowing snow. Low: 10°. Wind: NW 10-20 mph.

TOMORROW: Cloudy and cold. High: 18º.
