Interesting. WPa has historically been pretty big a winner with SSW's

Good signs hopefully, with the possible SSW taking place.

Not looking like it will materialize as hoped.

What does a strong El Niño mean for Pittsburgh snow?

Historically it has meant less snow and a warmer winter. Across the nine winters NOAA's index classes as strong or very strong El Niño events, Pittsburgh averaged 31.2 inches of snow against a long-term mean of 42.9 inches. Eight of those nine finished below normal.

Here is every one of them, with the airport's own measured total. The ONI peak is the highest three-month value the event reached, which is how NOAA classifies event strength.

Winter	ONI peak	Class	Pittsburgh snowfall	vs 44.1" normal	Dec-Feb temp
1957-58	+1.81	Strong	37.0"	Below	28.5°F
1965-66	+1.98	Strong	48.0"	Above	30.3°F
1972-73	+2.12	Strong	26.3"	Below	31.9°F
1982-83	+2.23	Very strong	30.1"	Below	34.1°F
1987-88	+1.70	Strong	35.1"	Below	30.2°F
1991-92	+1.71	Strong	33.9"	Below	33.4°F
1997-98	+2.40	Very strong	24.2"	Below	36.3°F
2015-16	+2.75	Very strong	29.6"	Below	34.9°F
2023-24	+2.06	Strong	16.3"	Below	38.4°F
