@wxindy @TDSwx That’s JFM, here’s DJF using the SFS hindcast climo.

@wxindy @TDSwx AI is very bad at visually analyzing and interpreting anomalies

[Dr. Jonathan Wall @wallcloud]

@TDSwx My map. The SFS is by far the snowiest solution out there. Probably very incorrect.

@akrherz several iembot accounts look to be posting live now https://t.co/MWdYgLpcKQ

@WxCustomize Tried my best! Any other suggestions or feedback I’d love to hear it George!

North Carolina measurable snow occurrence during El Nino winters based on teleconnection phase (-/+)

These maps are available for 48 states on Snow Signal.

@webberweather Someone is going to get absolutely pasted in February though

@mattlanza @amarkowitzWX Unless your account is solely for informing people, like an official NWS account, sharing maps for engagement is what X is for.

If you have a name of a specific statistical test I’ll run it on my data. I’ve done most. Unfortunately the closest stat sig p values are with -AO which is probably the most obvious anyway without even doing the tests. And I’ve tested 16 other parterns, MJO, TNH, nothing I’ve found so far is worth displaying but the teleconnections listed on the site. The most obvious background states are the ones driving the snow usually.

[Dr. Jonathan Wall @wallcloud]

@thealepalombo Sooo best climate but you only map temperature and no rain, excluding humidity, clouds, wind and lows?

[Dr. Jonathan Wall @wallcloud]

@WxCustomize We would probably need a bigger sample size, this is only 27 Niño winters back to 1950. And honestly I wouldn’t want to go back to the 1800s because then you’re getting into an entirely different climatology and it probably wouldn’t survive any kind of sig tests

[Dr. Jonathan Wall @wallcloud]

@WxRiskGrains Yeah I think so

[Dr. Jonathan Wall @wallcloud]

@TrackerSacker Driven by El Niño winters, the opposite signal is shown for La Niña.

@quagmirewx The, if you want a shareable map, click download png.

[Dr. Jonathan Wall @wallcloud]

@quagmirewx Pick your CWA from the main page, click “map” in the top menu, then state map tab. Be sure to change what you intend to map.
