frd Posted January 28, 2024 Share Posted January 28, 2024 DT update 3:57 PM · Jan 28, 2024 · 9,047 Views WORKING HYPOTHESIS so if we accept the idea that the northern Jet Stream is overdone then the southern LOW is not along the Gulf Coast on FEB 4-5 . It will be back in the Tennessee Valley and the big snowstorm threat is still alive. IMAGE 2 shows the individual 30 members of the 12z GFS Ensemble . Of the 30 members ….13 of them show a significant surface LOW that would bring significant snowfall to the Middle Atlantic region. some of these Solutions also include the northern Mid-Atlantic and New England. Some do not. Given the GFS propensity to overdo the northern branch and suppress southern systems 13 out of 30 is almost 50% which is not bad. 2 Link to comment Share on other sites More sharing options...

ncforecaster89 Posted January 29, 2024 Share Posted January 29, 2024 Hi everyone! Thought I’d simply share some of the statistical research I’ve been conducting most recently…examining the correlation between El Niño and seasonal snowfall in the Eastern U.S. Here’s the link to the post showing how each of the 5 selected Mid-Atlantic cities all saw a VERY significant decrease in seasonal snowfall during strong El Niño episodes. https://x.com/tbrite89/status/1751700478864265580?s=20 On the flip side, a few of the largest snowstorms occurred during a strong El Niño season such as 2016 and 1983. In essence, strong El Niño seasons are generally boom or bust and highly reliant on a KU event to achieve the climatological average. 1 Link to comment Share on other sites More sharing options...

I'm surprised Philly's mod Nino average (52.2") is a lot higher than Baltimore's (35.6").

Expand No doubt I’m going to have to go back through each individual year to verify the accuracy of the data I compiled. Thank you so much for catching those inaccuracies. I shouldn’t have relied on second-hand sources. Simply trusted the data…as they had already compiled the yearly totals for virtually every observing site in the nation. Thereby, saving myself a tremendous amount of time. I verified their totals for my home city (Wilmington, NC) and they matched perfectly. With that, I wrongly assumed the rest of the data for the other respective cities were entirely accurate as well. Link to comment Share on other sites More sharing options...
