A DENSE FOG ADVISORY will remain in effect until 10 am for portions of north-central, central, and south-central Montana.
After a picture-perfect Christmas weekend, widespread low clouds with areas of dense fog will take us through the morning for portions of north-central, central, and south-central Montana. By mid-morning, the fog will dissipate, and a ridge of high pressure will build to our west and will offer up partly to mostly sunny skies. The high temperatures for today will stay in the 20s and 30s. A flood advisory has also been issued for the Jefferson River near three forks due to an ice jam. If you happen to encounter any barricades in flooded roads, turn around and do not drown. Under clear skies, tonight's temperatures will fall to the single digits and teens.
Tomorrow mild temperatures will stick around. The highs will again trend in the 30s.
Wednesday, ridge of high pressure will begin to break down by a disturbance in the upper atmosphere. The clouds and the wind will increase, and as of now, the National Weather Service has not issued any high wind watches or warnings.
The passage of Wednesday's disturbance will kick off snow in the mountains along the Idaho border; if traveling across mountain passes, prepare for slick conditions.
Happy Holidays.
