The one good thing we can say about the guidance from 7 days out was it saw the coastal storm signal. But the slower evolution and cutting off allowed heights to rise too much in advance of the storm. So their won’t be much cold available when the storm arrives. New run Old run

The 5 year snowfall average is under 20” at several locations since 2018-2019. The WPAC warm pool preventing the El Niño from coupling in 2018-2019 began this period. So a persistent La Niña background state has dominated most years. While long term averages at places like NYC are still in the 20s, these 5 year averages can be useful at detecting change points. If the current 5 year average represents a shift, then NYC 30 year average snowfall may eventually dip under 20” in the long range. https://www.climate.gov/news-features/blogs/enso/csi-enso-case-missing-central-pacific-rainfall Monthly Total Snowfall for NY CITY CENTRAL PARK, NY Click column heading to sort ascending, click again to sort descending.

A seasonal forecaster wouldn’t have had any misses since 2000 if they simply said the snowfall range at Islip would be outside 18-30”. But the real trick is knowing whether it would have been over 30” or under 18” before the seasons started. Getting some type of extreme has been a sure bet to make before the seasons began.

Every season since 1994 has been all or nothing on Long Island. More in the middle seasons before 1994. So our snowfall cycle has become more amplified or extreme with higher highs and lower lows. The 18-30” season used to be common with 1999 being the last one. Time Series Summary for ISLIP-LI MACARTHUR AP, NY Click column heading to sort ascending, click again to sort descending.

Main difference between now and 2018 is we have much less seasonal snowfall before this one. So the background pattern has been less conducive for snow than 17-18 through early February. SSWs following less snowy periods like 2001, 2009, and 2019 didn’t produce as much snow. So the seasonal pattern before the SSW can be just as important. Just look at the list below. So a SSW can’t reorder the whole seasonal pattern. But it may be our best chance for accumulating snow. https://csl.noaa.gov/groups/csl8/sswcompendium/majorevents.html

The 12z Euro and NAM from yesterday came the closest to the 3° low in NYC. The HRRR was too cold while the GFS and CMC were too warm. The Euro usually corrects its longer range cold bias in these situations beyond 120 hrs once within a few days.

It was their warmest also. So the -10 in February is a big mismatch. They got down to -10 in February 1918 also. But -3 that January instead of just 23°.
