Today’s a good day to have committed to NC State. Elite 8! 🐺

My computer died, and I lost most of my programming files. So, I took that as an opportunity to download the updated ERA-5 data back to 1940. I think most of us along the East Coast would be satisfied to see a March 1960 repeat - because I'm a weenie.

Once again, I decided to have a little fun in Python 🐍 today & created some Dec-Jan-Feb-Mar CONUS surface temp & 500mb height anomaly probability + mean composites for El Niños since 1855 using NOAA's 20th Century Reanalysis! Unlike the previous set of composites I showed in…

I've been experimenting with creating various ERA5 climatologies recently. To make sure the results look as expected, I plotted the daily change in average 2m temperature, nicely showing the contrast between land & water, as well as the change in seasons and monsoon/ITCZ:

I finally found enough time today to analyze this past Christmas's cold wave in North Carolina. Widespread sub zero lows occurred in the mountains, w/ 0s & 10s in much of the piedmont + coastal plain Mt Mitchell was the cold spot, getting down to -21°F 🥶 #ncwx #wncwx #scwx

Here is the other Blizzard of '78 across the Ohio Valley and Great Lakes.

Okay, I just downloaded the Euro Runs for December 2010. Let's see what kind of analysis I come up with. Here's a run from 6 days out.

On the topic of ECMWF datasets, I discovered the CERA-20C, which goes back to 1901, and seems to be more reliable than ERA20C. I plotted the March 1927 Snowstorm. @webberweather you may appreciate this

A lot of weenies don't wanna hear this, but next week's pattern doesn't support big snow on the coast Nice deep trough over the OH Valley & -NAO yes, but there's no trough near Atlantic Canada & the ridge off the West Coast is too far west >> Interior NE US & Great Lakes favored

Decided to correlation DC snowfall with 500mb heights for December and January. Interestingly, high-latitude blocking (-AO, -NAO) heavily correlates to Dec snow, while a Western US ridge (+PNA) is much more important for Jan snow. Additionally, a +EPO is favored for both months.

At the request of @webberweather, I also ran a +/- lag composite of major -EPO events (<=-2.5). Interesting regression from the Western US to the Bering Sea.

You can definitely see the evolution from a Scandanavian ridge to a Greenland ridge with this view of the strong -NAO composite.

With the upcoming potential major -NAO, a lot of people were interested in the lag composite for major -NAO events. I know @burgwx plotted this with CFSR, but here is the map with ERA-5.
