I believe that was one of the earliest snowfalls on record for Spokane.

The airport picked up some decent snow in late September last year. We didn't get much in town or out in the valley. This was the first big one for most of the city. It was still pretty impressive.

Looks like probably a 50% chance we will at least get brushed by Canadian air next week.  Decent shot at our first lows in the 30s.

Meanwhile a ridiculous trade wind burst is about to commence in the tropics.  It appears this will be one of the premier strong first year La Ninas on record.  Past similar instances show seasons like this can be slow starters, but usually deliver big time later on.

The sun has now had a 50 day stretch where only two days had spots.  If this keeps up we may top the Dalton minimum.

At face value I would say that run delivers some frost to the Western Lowlands with seasonable sunny days.  Pretty delightful if that were to verify.  I like that it shows the surface gradients remaining northerly so we won't have to deal with down sloping.

October 2010 wasn’t nearly this warm and ridgy.

Doesn’t have to be perfect. The large scale wave trains are (relatively) close matches.

Big league 1st year niñas/+QBOs like 1988 and 2010 both had relatively ridgy early/mid autumns out there.

The 500mb was a pretty ugly +PNA though.

This reminds me of 1988 very much for observed weather.  Another year that was kind of similar was 1942.  Slow starter and then we got hammered.

Much of autumn 2018 was ridgy out there too, and that winter was kick a**.

2/3 of that winter (December and January) were absolute garbage.

Of course observed weather in the fall seems to mean very little as to how the winter goes. I like cool fall weather on its own merit. The entire year isn’t just one big winter setup. Although much of this forum seems to view it that way.

Pretty sure we had a nice Christmas Eve surprise, the PS had a legitimate White Christmas along with a nice run of cold highs.  Hard to throw that in the absolute garbage category...

I just did. Didn’t seem that hard...

I think you are thinking of December 2017 btw.
