The general tendency is -H5 near the Poles, with +H5 in the mid-latitudes, but it's a pretty weak correlation (0.10-0.15) that far out. I've run several individual cities record breaking warm patterns out at different times, and that's what the constant theme is (warm mid-latitudes, -h5 near the Pole +several months time).

^For the last 3 years (23-25), RONI has been -0.533c the value of ONI month-by-month (0.0 ONI is -0.53 RONI). Staying the same.

0z GEFS look much stronger with -WPO in the medium range. I'm going to have to learn that the EPS has much better accuracy than GEFS.

Sorry to dwell on the Winter West Coast ridge again, but this really stands out to me as an extreme anomaly Most extreme West Coast DJF ridge analogs The news is, the ridge really sticks around +time in analog cases.. this is the following year: March (not included in my visual analog picks.. yet almost as strong of an anomaly!) April (+60dm over the SW, US is extreme!) May Summer (June-August) Following Winter (26-27 analog) ^75% of the N. Hemisphere is +H5 in the following Winter, which fits a warming sequence possibly associated with El Nino. The main point is just the skew warm-general +time. This is the mid-latitudes the following Winter (26-27 analog) Winter PNA DJF 25-26 was negative, so interesting that they got a #1 record warm Winter on the West coast. Monthly PNA: -1.41 2026 0.79 -0.56

0z GFS with a 80F sounding for DC March 11. NWS has it anyway Tuesday Sunny, with a high near 80. Tuesday Night Partly cloudy, with a low around 64. Wednesday Partly sunny, with a high near 79

It doesn't look that impressive on the H5. Ongoing +NAO looks just as impressive. +NAO/-WPO if we get a frozen storm, it's more likely to be ice than snow.

Has there ever been a snowstorm in mid-March with a +2std NAO? I know 1993 had +nao, but don't think it was a strong as +2

All the roll-forward stuff from the Winter was suggesting March would be near normal to below in the eastern 1/3 of the US.. seems to be beating the Euro weeklies in the long range

Models have really come around to a better looking Pacific..

Yeah, but this is the 500mb pattern, super unfavorable on large scale as a sustained thing, it's taking a few days to change the surface.

Thank you donsutherland for Phoenix, AZ statistics.. this was their warmest Winter on record by a lot. The difference between 1 and 2 is almost the same as 2 and 20. Climate analog point - the pattern that follows April-June of the analogs is below, notice the -H5 up north and -PNA in the Pacific. I've seen this when DC hits a record Winter high temperature or some other US city, the Polar area gets negative anomaly, and there is more ridging at the mid-latitudes +months forward: April US Temps (+2-4 months, some progression east)

29F. I'm surprised Winter is holding on this strong, to be honest. And our last few temperature dips have coincided with precip, it's usually the other way around.

24.5" total. I was always saying Winter average here is close to 30", but it's probably 25" now.

Records just keep dropping in PHX, does it have the greatest rate of warming in the world, of major cities?

This is a little bit of a misconception. Does a Super La Nina mean brutal cold?
