brooklynwx99 Posted Friday at 04:59 PM Share Posted Friday at 04:59 PM can't really ask for much more from a general synoptic perspective here. 2.5-3 sigma ridge in an ideal spot with a potent vort diving into the Plains. details will get ironed out but it's nice to see the models keying in more on the second wave 2 1 Link to comment Share on other sites More sharing options...

TIA. very strong ridging will encourage some kind of low pressure (potentially strong) somewhere over the E US. not sure how the first wave will impact the second as the ridge in the west builds, but models are beginning to key in one the second one more and weaken the first a bit. the pattern is favorable for some kind of coastal. the jury is out on how and where a storm forms (if one even does) 2 1 Link to comment Share on other sites More sharing options...
the_other_guy Posted Friday at 06:21 PM Share Posted Friday at 06:21 PM I don’t understand why guys keep laughing at the possible snowstorm. This is a weather forum. A possible snowstorm in December in New York. It’s not like talking about a hurricane hitting Iowa. I just don’t get the craziness with the disbelief at the possibility 6 Link to comment Share on other sites More sharing options...

Agree. One saving grace so far is that we do have cold air around so maybe sneak something in-last December was very warm overall so we were toast. 2 Link to comment Share on other sites More sharing options...

donsutherland1 Posted Friday at 10:14 PM Share Posted Friday at 10:14 PM A much colder air mass now covers the region. The cold will last through the weekend before milder air returns early next week. It could then turn unseasonably mild for a time. Additional rain is possible early next week. Following the rain, it will again turn somewhat colder before a much sharper shot of cold arrives for during or after the next weekend. Beyond that, the pattern will likely remain changeable through much of the rest of the month on account of a fast jet stream. The overall anomaly for the final week of the month is unusually uncertain with most of the ensemble guidance and the weekly guidance in disagreement. However, the probability of a mild end to the month and mild start to January has increased. The NAO fell to a preliminary -2.751 on September 24th (all-time September record: -2.371, September 12, 1971). That was the 9th lowest value on record. La Niña winters following September cases where the NAO fell to -1.900 or below featured a predominantly positive NAO. The most recent such winters were 2016-2017 and 2022-2023. The mean temperatures for those winters in New York City were 39.3° and 41.0° respectively. The 1991-2020 normal value is 36.2°. A warmer to much warmer than normal outcome is favored by the November run of the ECMWF for Winter 2024-2025. The ENSO Region 1+2 anomaly was +0.1°C and the Region 3.4 anomaly was -0.3°C for the week centered around December 4. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.12°C and the ENSO Region 3.4 anomaly has averaged -0.20°C. Neutral ENSO conditions may still evolve into a La Niña event during the winter. Uncertainty as to whether a La Niña will actually develop continues to increase. Currently, 47% of dynamical models and 22% of the statistical models forecast the development of a La Niña. The SOI was +5.66 today. The preliminary Arctic Oscillation (AO) was -1.050 today. Based on sensitivity analysis applied to the latest guidance, there is an implied 73% probability that New York City will have a colder than normal December (1991-2020 normal). December will likely finish with a mean temperature near 37.5° (1.6° below normal). Link to comment Share on other sites More sharing options...
