Winter Storm Warnings Expanded

*Another significant winter weather event is on tap for the Black Hills… the biggest threats will be slick roads and a dangerously cold New Year’s Eve!*

Winter Storm Warnings have been expanded to include Pennington and Meade counties, as well as much of the Black Hills.

Sunday afternoon radar shows snow in the Hills, rain elsewhere.

TONIGHT: Temperatures will drop quickly, causing any rain to change to snow. Any moisture on the road surfaces will turn to ice. Slippery roads will be a primary hazard. Blowing snow also a problem to contend with. Temperatures will drop to about 7°F overnight, with snow developing. Winds will increase to 20-30 mph gusting to over 50 mph. Wind chills will be around -20°F by daybreak. About 2″-4″ of snow is possible in the Rapid City area.

Snow becomes widespread on Monday morning.

TOMORROW: Snowy and very cold. Highs will only be about 8°F, with winds gusting to 45 mph. Wind chills as low as -25°F. Another 2″-3″ of snow possible before the storm exits the region.

Bone-chilling winds for New Year’s Eve.

Yep, a significant snowfall for New Year’s. The Black Hills, Rapid City, and the east central plains seem to get the worst.

NEW YEAR’S EVE: Bundle up! The snow will end, but it will be dangerously cold, with overnight temperatures dropping to about -5°F and wind chills near -25°F. Mostly cloudy skies.

Mild after New Year’s.

NEW YEAR’S DAY and BEYOND: After a wild transition from 2018 into 2019, the rest of the week looks quiet, with partly cloudy skies, and temperatures in the 40s and 50s through next weekend.
