Seeing as one of those January days had a low of -2...yep, sounds like it, lol Ya had only 4 days the entire month get to 40 degrees! Snowfall, on the other hand...was 8.5"...and we only measured a trace for the rest of the season. Oof...and seeing as the next year was a Niño, I wonder if 1976-77 was indeed a dying nina like this one seems to be. Rather paltry results in the snowfall department...and February torched as you'd expect, lol

Anybody got what they indices (AO/NAO/PNA) were that winter?

0z AIGFS has 2 snow threats. One starting at 210hrs:

The other threat starting at 288hrs:

Unfortunately, neither Tropical Tidbits nor Pivotal have pretty surface maps showing snow, only precip. But if you use those TT links and look at Pivotal 850, 925 and surface temps, it's snow, or rain to snow depending on exact location.
