The first week of February is proving itself to be typical of Missouri winter after a mild day in the 50s today, with more rain and much cooler temperatures on the way by tomorrow.
By the weekend, we'll be tracking arctic air and a fast moving Alberta Clipper system that will bring a chance of snow on Saturday, along with frigid air as a portion of the polar vortex slides south over the upper Midwest.
Snow chances increase from northwest to southeast as the disturbance slides over the area early Saturday into Saturday night. Since this system will be moving somewhat quickly and lacking a large amount of moisture, snow amounts will be on the lower side, but we could end up with a dusting to a few inches of snowfall. Amounts will be easier to nail down as we get within 48 hours to determine how much moisture content we're working with. We could see slick roads late Saturday morning into the afternoon if snow starts to accumulate with temperatures below freezing all day.
Strong winds are expected over the weekend as gusts get up to 25 mph out of the northwest. Wind gusts will send wind chills on Saturday into the low to mid-teens. Air temperatures on Sunday morning fall into the low single digits, with wind chills settling below zero through late morning.
A Weather Alert Day has been issued for Saturday night through Monday morning for subzero wind chills. Conditions will be dangerous to be outdoors for longer than 10 minutes at a time if proper cold weather gear is not worn.
