GILLETTE, Wyo. — Warmer air is moving into the region again today, and that will help boost temperatures into the 40s for the first half of the week.

The National Weather Service in Rapid City, South Dakota, forecasts a partly sunny Monday with a high near 41. With winds from the southwest 11 to 17 mph and gusts to 26 mph, early in the day wind chills may dip as low as 12 degrees. Tonight’s skies should be partly cloudy with a steady temperature around 38. A southwest wind 18 to 20 mph may gust to 30 mph.

Tuesday should be the warmest day of the week as a tightening pressure gradient moves the mercury up. Under increasing clouds, the high should reach 45 degrees. Winds will pick up from the southwest to 21 to 28 mph with gusts to 41 mph.

Winds in southern Campbell County on Tuesday may be strong enough for a high wind warning, meteorologists said in forecast discussion.

Winds for Tuesday night should subside a bit to 15 to 23 mph with gusts to 34 mph as the low falls to 31 degrees under a mostly cloudy sky.

“By Wednesday morning we see a pattern shift, as upper troughing digs into the western (continental U.S.), with a couple chances for
precipitation,” meteorologists wrote in forecast discussion.

For Campbell County, Wednesday carries a 30% chance for rain and snow, mainly after noon. Skies will be mostly cloudy as the high reaches 41. Winds will have died down substantially from Tuesday to 10 mph. Gusts could reach 17 mph after winds shift to come from the northwest after noon.

A 20% chance for snow is possible before midnight Wednesday night, the forecast states. Expect mostly cloudy skies and a low around 24.

High temps the rest of the week will hang just above freezing, with forecast highs of 34 degrees on Thursday and Friday. Lows each night will dip into the high teens.
