The end of 2018 will see more frosty mornings and mild afternoons. It will be breezy at times especially Monday, New Years's Eve as a dry cold front passes overhead.
The New Year will ring in more cold dry weather both for the valley and the mountains, with no threat of precipitation except for some isolated snow flurries in the mountains late Sunday and into early Monday. Expect temperatures to be in the 30's at night and mostly in the fifties during the day in the valley and teens and 20's at night in the mountains with day time highs in the 30's and 40's.
The weather looks to remain dry until around Saturday January 6th when a pattern change will bring wet weather with rain and snow back to the region.
