Weather Eye: Overnight lows will dip below freezing next week

Wednesday was a nice day to dry out before the next Pacific weather system was knocking at our door. We have rain and showers today before another weather system rolls in later on Friday. That will bring steady rain and showers over the weekend. There will be plenty of good snow in the Cascades and that will include the mountain passes, with snow falling pretty much non-stop Friday night through Sunday.

Then we enjoy perhaps all of next week with sunny skies. It will feel more like December weather with highs in the mid-40s and lows at or below freezing. For those of you that haven’t had a good freeze yet, mainly in the inner city of Vancouver, you will next week. So those summer flowers still showing life in outdoor pots may finally succumb to their end of life.

Gusty east winds will blow, adding to the wind chill. This will not be a cold air mass as temperatures in the upper elevations will be in the 40s and 50s. Think inversion. The coldest overnight lows will be, of course, in outlying calm regions of the county.

Central and Eastern Washington will get colder each day as warm air aloft traps the colder air near the surface and low clouds will form and bank up against the Cascades. So next week will see plenty of sunshine on the west side, but have that holiday nip in the air, allowing everyone a good chance to be outside without freezing snow and ice.

It will be curious to see what nature has up its sleeve later in December as far as a threat of lowland snow. At least we get off to a much better start to December than last year, when it rained almost every day the first week. Overall December 2016 was much colder than normal, with the average mean temperature of 36.8 degrees, nearly 4 degrees below average.

Get through the next four days and then we have it made for a while. Hopefully the ski areas will get enough snow before it clears off to reopen. See you on Sunday!
