This is a continuation of the misalignment discussion. Niño-like ridge near Hudson Bay and Niña-like ridge NE of Hawaii. Almost a combination of the 97-98 and 11-12 patterns at 500 mb to close out January. -

This looks like the first time since 2010 that the NYC January minimum temperature finishes warmer than December.

Historic event for that part of Canada. https://weather.gc.ca/warnings/weathersummaries_e.html#NL Weather summary for Newfoundland issued by Environment Canada at 3:00 p.m. NST Sunday 19 January 2020. Discussion. A powerful January storm brought intense winds and record-breaking snowfall to parts of Newfoundland on Friday into Friday night. A new all-time daily snowfall record was established at St. John's International Airport. New record: 76.2 cm (January 17, 2020). Previous daily record: 68.4 cm (April 5, 1999). Records began in 1942. The above total is applicable for the January 17 climatological day, which is a 24 hour period ending at 2:30 A.M. NST on January 18. An additional 2.0 cm was recorded after 2:30 A.M. The area of low pressure responsible for the snow and wind emerged from the northeastern United States early Thursday and began to rapidly intensify as it moved over the Gulf of Maine. The system deepened into a powerful storm as it tracked southeast of the Avalon Peninsula on Friday, before departing into the North Atlantic early Saturday. The storm battered the eastern half of the island with heavy snowfall, extremely high winds and damaging coastal storm surge. The following is a summary of information received by Environment and Climate Change Canada as of 2:30 P.M. NST Sunday. Total snowfall (in centimetres): Mount Pearl: 93 Paradise: 91 St. John's East: 82 St. John's International Airport: 78 Mount Carmel: 61 Lethbridge: 48 Gander International Airport: 35 Gander West: 35 St. Lawrence: 31 Grand Falls-Windsor: 10 Maximum wind gusts (in kilometres per hour): Green Island, Fortune Bay: 171 Bonavista: 164 Grates Cove: 156 Heart's Delight-Islington: 156 Cape Pine: 146 Green Island, Trinity Bay: 145 Twillingate: 140 St. John's - Doheney Place: 134 St. John's - East White Hills: 132 St-Pierre: 130 St. John's - Dockyard: 129 Pass Island: 126 Allan's Island: 116 Holyrood: 114 Bishop's Cove: 113 Ramea: 109 St. Lawrence: 106 Burgeo: 105 St. John's West: 105 Deer Park: 101 North Harbour: 101 Gander: 97 At St. John's International Airport the official wind sensor malfunctioned during the storm. Reported winds were estimated to be between 65 and 85 knots (120 to 157 km/h). However, it will likely not be possible to provide a verified maximum gust. The wind sensor at Gander International Airport also briefly malfunctioned. The highest gust at the nearby Gander climate station was measured as reaching 97 km/h. The following area set a daily minimum temperature record on January 18, 2020: Winterland Area (Winterland Branch Hill) New record of -17.9 Old record of -17.8 set in 2001 Records in this area have been kept since 1970 Note: the temperature record reported here has been derived from a selection of historical stations in this geographic area that were active during the period of record. Please note that this summary may contain preliminary or unofficial information and does not constitute a complete or final report. End/NLWO

Yeah, we need extreme -EPO or -NAO blocking to get a colder than average winter here. Otherwise, the default pattern has been warmer than normal winters. We got the record -NAO blocking in 09-10 and 10-11. This was followed by the record -EPO blocking in 13-14 and 14-15.

Funny how March was the snowiest month of the season for 4 out of the 5 last years in NYC. This is more typical for the Rockies and Plains than NYC. Will February be able to score a victory over March this year? Maybe the extra day in February this year can grab some snow away from what would have normally been March 1st.

Thanks. The good news is we still never had a season that was a complete shoutout. Even in the seasons with the most challenging patterns, we have always found a way to get at least some snow. You wonder how bad the pattern would have to be for NYC to finish with just a T or 0. I think Philly came close in 72-73 with a T. But NYC always had at least some accumulation. -

While all the models struggled with the EPO forecast, at least the Euro and EPS were closer to reality. Always be weary of long range model forecasts that go against the seasonal background state. That’s why there’s no harm in waiting for an actual pattern change to show up in the short term. -

Great post, Tom. Misalignment has been a common theme recently. Last winter we saw the the Niña-like warmth in the WPAC result in the uncoupled El Niño. So we had the Niña-like ridge axis stuck north of Hawaii. This year we have experienced a continuation of that persistent ridge axis north of Hawaii. Now we are getting the amplification of the ridge in SE Canada with the Niño-like +AAM spike. But a piece of that ridge north of Hawaii holds on into the 6-10 day forecast. https://www.climate.gov/news-features/blogs/enso/csi-enso-case-missing-central-pacific-rainfall -
