WEATHER DISCUSSION: Warm and dry conditions continued across the area today as upper-level high pressure remained overhead. The highs reached into the lower to upper 50’s with lows in the 30’s later tonight. Clouds will gradually build in from the south and west with some incoming and much needed precipitation on the way.
A quick moving weather system will break the trend of warm and dry days as it moves in overnight tonight and through Saturday. As this system pushes through, expect winds to sharply increase with most areas seeing wind gusts to 40-50 mph along and behind this cold front as colder air works in. Expect temperatures to dip into the 30’s for the weekend with overnight lows in the teens for the most part. In addition to the gusty winds and cooler temperatures, this system will also bring along some mostly mountain snowfall along with it. This has prompted the issuance of several Winter Weather Advisories in portions of western and southwestern Montana. These Advisories will end in varying times Saturday and Sunday with 2 to 8 inches of snow fall expected and more accumulation in high elevations. Especially as you make your Christmas travel through the weekend, watch for possible slippery conditions as lows dip below freezing and blowing snow.
While the colder temperatures will linger for the day on Sunday, the cooler weather will not last long. Upper-level ridging looks to build back in quickly bringing back high temperatures in the 40’s and 50’s and lighter winds. This pattern will likely hold through the end of 2023, keeping us warm and dry to close out the 2023 year.
