From Meteorologist Ethan Emery:
Sunday's cold forecast:
We are tracking more snow for tonight and Sunday across the South Dakota plains. This has prompted Winter Storm Warnings and Winter Weather Advisories to be in effect through part of Sunday. Areas in Winter Storm Warnings include Buffalo, Belle Fourche, Bison, Dupree, Faith, Lemmon, and Philip which will see an additional 1"-3" between tonight and Sunday with locally higher amounts possible. Areas in the Winter Weather Advisories include Wall, Lead, Deadwood, Spearfish, Sturgis, Union Center, Gillette, Moorcroft, Hulett, Four Corners, Sundance, and Colony, which will see an additional Dusting-2" between tonight and Sunday with locally higher amounts possible.
Areas from the central Black Hills and south will see less than an inch, including Rapid City. This does not excuse anyone from avoiding the winter conditions across the area between now through the end of the week as snow from Friday is still on most roadways and has caused slick spots. Winds on Sunday will be between 10-25 mph throughout the day, so areas of drifting and blowing snow are likely, so it is advised to drive cautiously. With these winds, wind chills will also be between -10 and -20 for most during the day, so wearing 2-4 layers of clothing is recommended. Cover up all exposed skin to prevent frostbite!!
Sunday will see snow showers begin to die down and move toward the east, though many will still see light snow flurries and snow showers during the day. High temperatures will be in the single digits to low teens for all locations in the area. Sunday night will be quiet as we see mostly cloudy skies, but colder conditions as lows fall below zero for most. Wind chills could go down as low as -20 in spots.
Monday, or George Washington's birthday, will be the coldest day of the 7 day forecast. High temperatures will be in the single digits for most while some parts of the Black Hills could experience the teens. 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. Teens and 20s look to hold in the forecast for daytime highs in Rapid City, but this is still well below average for this time of the year, and will continue through the end of the month and beginning of March. 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)!!
