I wouldn’t necessarily call one 18z run a trend. We shall see at 00z how it goes

Interestingly, if you break that down by storm type, that uptick actually has a lot to do with ice storms!

Could someone briefly explain what he means? Thanks in advance ?
You’re awesome Eric! I really appreciate your dedication to continue working on NC Climatology despite having left the state. I hope that this bring great use to me and my ERA-5 research plots.
I think this person is excited because this graphic has the MJO favored over the Western Hemisphere (ph. 8 and 1).
This is great Webb. Would be interesting to plot graphs of each decade or certain time period to compare it to the graph above
Don’t worry. It will change in 6 hours.
Probably not enough data to do that. You’d just see one giant spike at certain areas unless it was smoothed like crazy.
Decades would probably work, like we hear a lot that the 80s were a snowy decade, this would be a good graphical way to show it.

Thanks Nicky. Definitely recommend giving that big excel sheet a look, lots of cool stuff in there! I’ll progressively be expanding that, I want to add NOAA 20CR SLP based daily indices of the nao, ao, pna, etc and pair those with the maps I’ve already completed back to 1895, when COOP observers started regularly reporting snow to see if that additional 50 ish years of data changes anything.

Yeah the data is unfortunately too noisy for this to see any real trend :/. I already smoothed that plot earlier in the thread with a 15 day running mean filter. Maybe if you lump together several decades you may see something?! What I did notice tho is that ice storms seem to have a slightly earlier climo peak (by about a week) vs snow storms.
Eh I don’t know, I’ve gotten to use to rug pulls ?
ICON is a complete fail and was about to dump out west 
Actually, that trough off the NW coast was going to retrograde back toward the Aleutians and pump up the western ridge. We good.
I've already begun to play around with the file that Webber provided. Here is the MJO phase 6 correlation in December.
I think that piece would eventually cut off unlike in the GFS though.
