The reanalysis site has revised the data for October and it ended up at 4.90 which means it blew away 1961 for the highest October NPS.  November ended up at +0.7 which makes the combined value one of the highest on record since 1948.  The highest years for Oct and Nov combined were...

 

1948

1956

1961

1971

1978

1985

1990

2013

 

Al of these winters had major cold and many of them were among the coldest winters on record.  None of this grouped failed to deliver major Arctic blasts to the NW.  Pretty compelling stuff. 

 

That 1990 arctic airmass penetrated well into California and was the first time I recorded a freezing temp/ ice formed on the pool where I lived. Great memories.

Snow Wizard, any thoughts or update? Certainly some unbelievable blocking setting up, but too far east (over us). I think things will change eventually, hopefully before our window for real winter is over.

Jim has a tendency to short-change January 1959. I've noticed it over the years.  :lol:

 

That cold wave produced -55 in Montana and -35 in NE Oregon (at Minam). Also I believe some all-time record lows on the Colorado plains. 

 

Interesting, I've never really looked into that cold wave here. 1951, 1962, and 1963 were the big January cold events from that era I was aware of. I do see that DEN had a high of -1 one day with that event.

 

Yeah, I know I saw some all-time records from Jan 1959. They were either in SE Colorado or nearby areas of KS/OK/NM/TX. Pueblo was close....hit -28 on the 4th. Only -31 on 2/1/1951 and -29 on 1/28/1948 were colder. 

 

FYI if you're interested...Boise City, in the OK panhandle, set its all-time record low of -24 on 1/4/1959. Just ran across that reading while looking up numbers for a different post.

I have a lot of faith in this index when it's high in October and / or November.  I'm betting we score big somewhere in the late Dec to late Jan period.

I'm from Oklahoma and didn't know this one. Thank you.

Willing to bet this will all flip over to the proper sweet spot with the Kona low of your dreams come March/April and we will all be asking what would've happened if this came in December/January?

What do you generally regard as the greatest Oklahoma cold wave of all time? Obviously there was the state record in February 2011, but the one that really stands out to me is the December 1983 blast. A max of 5 at Tulsa and sub-zero at Ponca City. Pretty amazing.

Isn't it 1899? -17 at OKC is pretty good.

Up to this point this winter has featured extreme blocking, even if not in the right place. All of that looks to change next week with cold air pouring into the west.

Something good had better come soon! Socal has been almost completely rainless this entire fall and has been one of the driest falls on record down here and a horrible fire season for Ventura and Santa Barbara counties.
