12/2 Forecast Discussion: I can’t see!

Fog is reducing visibility in much of the Black Hills region, slippery roads and cold temps part of the story

CAUTION (12/2): Fog is lingering around much of the Black Hills, especially the northern foothills, where visibilities have dropped to below one mile. Temperatures as of 1 p.m. are also below freezing, so any moisture on road surfaces may become icy, especially toward evening.

Reported visibility across the region at about 1 p.m. Sunday.

TODAY: As yesterday’s storm exits the region, an area of high pressure is building in behind in. A convergence zone (where two rivers of air moving in different directions meet) has set up over the Black Hills, resulting in the cloudiness and fog in the region. The northerly component of these rivers of air, combined with the clouds will keep our temperatures mostly below 32 degrees Fahrenheit today. Roads may become slippery this afternoon and evening, as many road surfaces are wet.

TONIGHT: Continued mostly cloudy, and fog will persist in much of the area, especially in Spearfish-Sturgis-Rapid City corridor. Winds will be light. Overnight temperatures will be seasonable, in the teens.

Teens overnight are cold, but close to normal for early December.

TOMORROW: Cloudy with areas of fog in the morning, then the sun will make a valiant effort to reappear. Continued chilly with highs around 30.

TUESDAY AND BEYOND: No rain or snow is expected for the remainder of the week. However, keep those winter coats nearby! Highs all week will only be around 30 degrees…about 5 to 10 degrees below normal.
