Colder weather moves in next week

It’s been warm this fall and November is no exception. Our average temperature is 1.3 degrees above average and we are set to have the 6th driest November on record. This dry, mild weather pattern will continue through the upcoming weekend as temperatures remain above average.

Although December will start mild, by the 6th a colder weather pattern will start to set in. The jet stream which is a river of fast moving air aloft will start to buckle as a ridge of high pressure develops on the west coast. Upper level winds will ride over the top of this ridge into northern Canada and dive south into the United States.

The first surge of cold air arrives Tuesday, December 6th as a surface cold front moves through. Temperatures will fall into the 40s during the day and into the upper 20s at night. This will be followed by another surge of Arctic air later in the week that looks like it will hang around through the weekend. Medium range forecast models indicate that this pattern will persist through the middle of December.
