October 2020 Weather Observations for the PNW


Recommended Posts

The Euro still goes for highs in the mid 40s on Friday for this area.  That is going to feel downright cold.  Still looking like mid 20 to low 30s Saturday night.

Good inversion pattern.  It's quite interesting how this looks nothing like last nights run.

Funny he posts this just before a significant cold snap.  It kind of undermines the whole premise.

.... And the very exciting Day 10

I want this over a flatter mild / wet pattern.  At least the ridge will bring an inversion so late in the season.  I have no complaints.

Another thing...it's October.  I'm thankful for the cold wave that is coming.  The big longer lasting stuff will come later.

I have a feeling this winter will be blocky. Blocky is a good thing.

Indeed.  In the winter a big cold wave followed by a ridge right over us is pure gold if there is snow on the ground.

It looks like a dense fog pattern.

Not what it shows... and the ECMWF is pretty good at inversions.     500mb pattern will probably change of course.

We often struggle in Spokane. From late October until early to mid February. We'll get socked in with low clouds and fog. I always welcome the sunshine if I can get it.

Might have been overlooked... but the current pattern is also very blocky.

Of course this is a terrible pattern for the Seattle area with a persistent c-zone.     Can't wait until things start moving again regardless of what that means.

People think eastern WA is so sunny in the winter compared to the west side... but that is often not the case.

For what it's worth (just about nothing...), the 06z NAM is markedly improved over the 00z, though blocking is further east, so it could just be a flukey run. Still got another 36 hours before the Aleutian low begins taking form. Go GFS...?

And Sunday has a chance for SEA to see their earliest 30 degree low since 1949.  Pretty intriguing.

To add to the intrigue... Billings October record snowfall is from 1949 with 23.1". They are already at 11.9" and will likely shatter the record by this weekend.

Thanks for this post. I saw how much they got the other day and then what is to come this week and thought, "that cannot be normal."

12z NAM - Already at Day 1 I can see the block and more notably the base of the block is a notch or two west, the contours in AB/BC to just off the BC coast is a few notches further west, and the block is a bit stronger as well. That may not look like much, but if these notches and small incremental changes are evident for several runs it can end up making a significant difference as I have documented many times in the past.

Past 3 runs (Improvements noted since 00z NAM run)
