Lotsa snow with that whole event though. 

Yeah for sure, but I hate to see it melt so quickly.

I would happily torch for the rest of the winter if it meant we could get another 12 day stretch like that.

Of course early January 1973 produced another nice arctic airmass.

The admin here is pretty biased and kind of a man child. No idea why I keep posting here, might just leave and go back to the comments of the weather blog.

I mean everyone gets cravings for weird foods sometimes, but Hannibal Lecter does and suddenly he’s the WORST PERSON EVER. Seems kind of biased to me Fred.

Those 10 day stretches at or below 32 degrees are a total waste and a dime a dozen.

I like the snow to remain on the ground for 2 months.

The new normal.

Hopefully the upcoming zonal flow will churn up those waters a bit and cool off the bathtub.

It look like the blob just explode and expand this year. Not too surprising with the ridge continuing to park offshore. A major shakeup is needed and perhaps the Pacific being in hyperdrive will change up the pattern.

RIP Phil Hartman

Died May 28, 1998.  Less than seven months later we had our coldest outbreak of the last 30 years!

Posted this morning about how SEA been stuck in a bubble where temps don’t move at all since at about 11am yesterday. temps just fluctuated between 48-51, but like to stay at 48-49 for most part.
 

Just here to report nothing has changed since and we are now to close to hour 36? It is expected to remain the same throughout the night tonight.  

[Brian_in_Leavenworth]

Forgot to post last night's 35 day GEFS, starting at day 17.  Not bad.

.55” so far on the day.

Interesting how the strat wave cycles are almost diametrically opposed to those last winter.

Probably means nothing but last winter did get off to a frigid start in Nov/early Dec with a pattern almost inverted from the present pattern, then torched the rest of the way.

That would be fine with me.  And yes, last winter did torch.  Got a lot of rain, especially after mid December.  That is torching by any definition.

Gutters fired back up.

Wow, that is freaky. Must be a weird coincidence.

Indeed. Ten lost days of highs in the fifties and mild rain.

[Meatyorologist]

Don't know if this was posted already, but some flakes in the air for Portland north mid next week on the GFS. Very brief and mixed with rain, but neat regardless.
