we've had an inch+ at our place in twisp in the last 24 hours. That on top of 3 feet of snow on the ground.....trouble

we just had 1.5" on rain on top of our 4' snow pack with another 1-3' of heavy wet snow coming in tomorrow. If the predicted break in the weather for late next week does not materialize I will need to get on the roof and shovel at some point.

Back home now, we were there December 28 through January 7.

Yeah it’s interesting. We took a trip to the east side of the island at one point (town called Hofn) which is more affected by the Gulf Stream than the Greenland current, and there was much less snow at sea level. That area apparently gets tons of rain though which translates to huge glaciers in the higher elevations. Vatnajokull is on that side of the island, which is the largest continental ice sheet in Europe outside of the Russian arctic. Kind of reminded me of a colder version of an Olympic Peninsula climate over there, minus any trees at all.

Vatnajokull is also known for producing massive outburst floods when the volcano under it called Grimsvotn erupts. Such a dynamic place.

My wife stayed in Mt. Shasta, CA last night, looks like they have some snow on the ground, not a bad climate. They are headed down to Sacramento for a wedding this evening. Was supposed to go with them, but didn't actually take the day off and then had some meetings get scheduled for today at the last minute.

They've already had over 9" of precip there this month.

It seems like the Portland area has been torching less than the Seattle area in this pattern. My warmest day is 57/46 and I’ve had four 55+ highs this month. Looks like I may reach or even break that 57 on Saturday. I’ll be in Leavenworth during that time though.

The Gorge has really helped mitigate the torching for the Portland metro. Pretty devastating to see both EUG and SLE with 60+ temps on the books for the year already. Especially considering both spots already hit that mark the last week of December as well. At least there was about a two month stretch with no 60s for the Willamette Valley before that, which is about the best you can hope for these days.

Haven’t been above 55 at our particular location since November 4th, which is one of the longest stretches in years without major cold season torching. Would have to go back to 2016-17 to find a similarly “cool” 2+ month stretch but it would be later in the winter season than this one. November 2016 was balmy.

Yeah, we drove the ring road right through that area, around the base of the volcano. Sounds like jokellhaups (glacial floods) have devastated towns and farmland in that area many times over the centuries.

Some pics from the area and a cool informative sign.

One silver lining in how awful January has been is that despite the extreme torching, or what has seemed like extreme torching, PDX and SLE are only 3.0F above normal. It's not unreasonable to think January still could end up near average. 

SEA will be around +4.5 for January after today.

Just noticed that last January finished at -1.8

Looking at the anomalies though, there is not really an difference between PDX and the rest of the valley, likely due to colder low temps further south.

I remember that being trumpeted by some of the Puget Sound cold fans. A little colder at the beginning of the month up there and a little bit stronger inversion later in the month if I recall correctly.

It was only -0.1F here as well. It was kinda chilly to start but then ended up back to the normal January stuff later on.

Yeah, then as the years go by you become a degenerate model rider like me, hanging on every July 18z CFS run.

Summer is that way for me... I always want to be outside.    I have no problem focusing on work in the winter though.

And BLI will be at +5.6 for January after today (and a shocking +7.2 for the average high!). Today is the third day this month they've recorded a 60+ high which ties the record from '92, '86, and '81. The only thing that has saved this month from being a complete torch at BLI is it seems to keep sneaking in freezes. It dropped to freezing on both Tuesday and Wednesday while it didn't even get below 40 here.

Here, my average low temperature for this January (43F) is currently approaching my normal average high for the month (46F).

Should mention a strong front comes through Wednesday. Could enough for convective showers to mix with snow post frontal. Also, this marks the end of the torch. 1674097200-UC74wRnLs9M.png1674054000-AxuGKyJhjs8.png

Not quite... ECMWF shows 850mb temps warm up pretty fast after that Wednesday trough.
