From Meteorologist Ethan Emery:
Monday's cold forecast:
Bitter cold air is moving in after all of the snow from Friday through this morning. Amounts varied across the region with reports ranging from an inch or two to a 18" snow report near Usta, South Dakota! Impressive! Fortunately, the snow showers taper off this evening and skies will be mostly cloudy, but that won't stop the cold air from flowing in.
Winds will be from the north between 5-15 mph, with gusts as high as 25 mph in spots. That will aid in having wind chills as low as -30 in parts of the Black Hills, which as prompted a Wind Chill Advisory for the Northern Black Hills, Central Black Hills, & northeast Wyoming. This includes the cities of Lead, Deadwood, Hill City, Mt. Rushmore, Gillette, Wright, Moorcroft, Hulett, Four Corners, Sundance, Newcastle, and Upton. These conditions can cause frostbite to occur on exposed skin in as little as 30 minutes, so make sure you cover all exposed skin, wear at least 3 layers of clothing, and limit time outside when necessary. Don't forget to check on neighbors, relatives, and pets that may be affected by this brutally cold air tonight into Monday morning.
Speaking of the wind, blowing and drifting snow is still a concern for travel tonight into Monday, so be cautious with travel tonight and for the morning commute on Monday as visibility could be reduced. The winds do begin to die down by daybreak, so this won't be a prolonged issue for most of the Black Hills.
Monday will also be quiet under mostly cloudy skies, but cold. High temperatures will be in the single digits for most with a few exceptions of teens in the Black Hills. Monday, or George Washington's birthday, will be the coldest day of the 7 day forecast.
Improvements are on the way as Tuesday looks to rebound in the teens and low 20s under partly cloudy skies. An isolated snow shower is possible for our southern counties, but right now most look to be dry. More sunshine and highs in the 20s move in by the middle of the week, but by Friday, light snow showers are possible once again. Amounts are uncertain as the system is too far out, but as we get closer and gather more data, we will alert you first on the air, online, and on our mobile weather app.
The weekend shows some warmer signs, as Saturday will see 20s and Sunday could even see 30s! Long-range computer models do bring back cold air for the following week, so another reminder that winter isn't over quite yet in the Black Hills! To end on a good note, remember that spring is just around the corner as the Spring Equinox is on March 20 at 3:58 p.m. M.D.T. (Daylight saving time begins on March 10)!!
