GILLETTE, Wyo. — Gillette can expect a brief flirtation with winter weather this morning, followed by a midweek warmup before a significant plunge into arctic temperatures this weekend.
Today, there’s a 40% chance of light snow, primarily before 9 a.m., with accumulations of less than an inch possible, according to the National Weather Service in Rapid City, South Dakota. Cloudy skies will gradually clear throughout the morning, leading to a high near 29 degrees. However, brisk northwest winds with gusts of up to 25 mph will make it feel much colder, with windchill values dipping to 16 degrees.
Drivers are advised to use caution as area roads remain slick with snowfall, per the Wyoming Department of Transportation.

The chill will continue tonight with partly cloudy skies and a low around 15. West winds will persist, bringing windchills as low as 5 degrees.
Wednesday promises a welcome respite with sunny skies and a high near 35. Although windchill values will still be low, reaching 12 degrees, the sunshine will offer a break from the recent cold snap. This warmer trend continues into Thursday, with sunny skies and a high near 38.
However, the warmup will be short-lived. By Friday, a strong arctic front will push into the region, bringing a 60% chance of snow, mainly after 11 a.m., and a significant drop in temperatures.
The weekend forecast is downright frigid. Saturday will see a high near 9 degrees with a chance of snow lingering into the morning. By Saturday night, temperatures will plummet to around minus 14 degrees. Sunday and Monday will remain bitterly cold, with highs struggling to reach minus 1 and 4 degrees, respectively, and overnight lows plunging to minus 20.
