There's some agreement for possible colder than average temps after the new year. Can't help but already look for snow signals lol1671883200-GAUrdfLQBkggrb2.png

Bonner's Ferry area? You all tend to do pretty well there. Always nice to have Idaho posters too since you're part of the region too.

Even with the long dry period this summer and fall, SEA looks to end the year just barely wetter than the yearly average. They will also likely end December wetter than average. They are still short on the water year but will be close to being above average after next week. Was surprised with how dry it has been in general in the northwest this year. NW Washington has been spared for the most part when it comes to lack of precip. 

This is why averages don't always make me feel good except for just data. 

Our forests don't necessarily care if the average precipitation was good because we had a really wet spring and somewhat wet winter with a really dry summer and fall. Our plants aren't acclimated to big bursts of water and then long droughts the way they are in other parts of the country. When it rains matters. Smaller bits of precipitation over more days vs a huge bit of precipitation in a short period of time and then dry weather (looking at you, June), may end up looking similar in the data but has a world of difference for flora and fauna.

Like Tyler said, if this had been the system coming Into the cold some areas would of had a once in a generation ice storm. We really got lucky. 

In my area... it seems like we went right up to the edge of disaster and then it warmed up just above freezing.

19F with freezing drizzle here. Pretty shallow cold layer. Up from 14F at 8am and 7F yesterday evening. Will probably touch freezing overnight tonight and be plain jane rain by tomorrow morning.

Until then, a total winter wonderland remains.

Weather will be pleasant up there with temps around 30 during afternoon and 20-25 at night. Would of been neat to be up there during the cold spell but it looks like it will be a very snowy week up there at that is hard to do during this period for the most part. I go up there every year after Christmas and it normally is dry. Even up there we might have 24 hrs or so will wet snow or mix. 3500 ft though so that should be right on the line for the warmest period Monday and Tuesday.  Or the arctic air will just hang around, very hard to remove it up there once it is entrenched.

It so cool seeing the contrast between the low level stratus and the eroding Arctic cold pool, and the very AR-like warm mid and high level clouds drifting in aloft from the SW. Also the advection fog in the lower 1000' as moisture mixes down into this cold air. Lots of meteorology going on.

Large batch of precip coming in from the west on the Spokane KOTX radar. Correlation coefficients suggest some snow making it to the surface in the heaver blobs due to wet bulb cooling.

Otherwise, a pretty impactful freezing rain event may be underway this afternoon into overnight. Just in time for my family's Christmas Eve party. 🤦‍♂️

Looks like you're just south of Greenwood, BC. We used to go up that way every year on the way to Christina Lake to visit my grandparents. I remember the smaller pass near Greenwood having a surprising amount of snow in the winter considering how dry some of the surrounding areas were.

We will probably hit or get close to average here. Will probably be the biggest rainmakers of the season so far in the next few days hasn’t been much in terms of big rains.

All in all I'm betting on the next two weeks being chillier than progged with the exception of the next few days.  Just the way things have gone this season.  It keeps finding ways to get cold since late October.

Wow, the melt here was incredibly dramatic. BLI rose from 33 to 48 in twelve minutes around 6 AM this morning. Almost all the snow is gone now save for the piles and a bit on the grass.

I actually like that it ended so suddenly, it makes the event more memorable. It's kind of like we were teleported to Minneapolis for a week and then back to the mild, rainy PNW. BLI eked out a high of 31 yesterday as the cold air held on in the lower levels, so that makes five sub-freezing highs in a row, along with four highs of 17-22 in a row, 8-12 inches of snow, and about a half-inch of ice. The snow came at the perfect time to be able to enjoy it for three very cold days and one more cold day with a regional ice event that would have been much more destructive without the sleet. Definitely one of my favorite weather events of all time!

Climbed as high as 34.3F earlier, back down to 33.2F. Slushy mess outside. That offshore flow not going down without a fight in the PDX metro. 

Don't know what the situation is like east metro but I can imagine the Gorge may be looking bad about now-- heavy moisture and still in the mid 20s.
