Dangerous Cold Today, Snow Tomorrow | Weather
Dangerous cold has overspread the area overnight. Temperatures are ranging from -9 to 0° area wide this morning. A wind from the NW at 20 mph is bringing wind chills down to near -30°. At these conditions, frostbite can form on exposed skin in a matter of 15 to 20 minutes so it is pertinent to dress warmly today. Remember extra blankets or clothes in the vehicle could be life saving should you become stranded and unable to seek help. Have your winter road kit ready.
Air temperatures today struggle to make it above the zero mark. Winds ease as the day progresses providing slight relief but the cold has a foothold on the area for the next three days.
Snow moves in early Friday and lasts into the evening. The picture below is a look at my prediction. Heaviest totals will come in from north central Iowa along US 18 where some places could see as much as 7" with isolated higher amounts. Areawide I expect to see a lot of 3-6" reports. Overall...
NC IA: 5-7"
SE MN: 3-5"
Along and just north of US 14: ~3"
Twin Cities: 1-2"
Des Moines: 1-2"
This isn't your typical Minnesota/Iowa blizzard. We're looking at lighter winds with this one. Along with temperatures near 10°, those two factors will let this system produce totals a little bit higher than what we might see with slightly warmer and winder conditions. A light (airy) fluffy snow is the result. A few spots may see snow fall rates approach 1" per hour which will make it all the more difficult to clear. Please, if you have plans to travel, do so with care. Also have that winter road kit handy.
