North and West Posted November 28 Share Posted November 28 The storm responsible for today's rain is now moving away from the region. In its wake, noticeably colder air will begin to move into the region. Below normal temperatures are likely for the remainder of November. On account of successive waves of cold, the first two weeks of December will likely feature mainly below normal temperatures. The long-range guidance remains in good agreement for a cold first half of December. Significant lake effect snow is likely. At least through much of the first week of December, precipitation will likely be below to much below normal in the region. 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 +0.8°C and the Region 3.4 anomaly was -0.1°C for the week centered around November 20. For the past six weeks, the ENSO Region 1+2 anomaly has averaged 0.00°C and the ENSO Region 3.4 anomaly has averaged -0.23°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. The SOI was +19.91 today. The preliminary Arctic Oscillation (AO) was -1.196 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 100% probability that New York City will have a warmer than normal November (1991-2020 normal). November will likely finish with a mean temperature near 51.4° (3.4° above normal). November 2024 will be the third November since 2020 with a monthly mean temperature of 50° or above. These are always super interesting even when I don’t understand half the things you mention. Do you automatically run these reports and gauges every day? Just interested in the process.. 1 Link to comment Share on other sites More sharing options...

Still usually we’re good for some flurries in November We had about an hour of wet snow after midnight that day last week. Link to comment Share on other sites More sharing options...

SACRUS Posted November 29 Share Posted November 29 43 / 30 clear and chilly. Mid - upper 40s today then colder the next 7 - 10 days. Opening of Dec coldest in a while, perhaps since 2010. WC large ridge with deep trough into the east, likely reinforced in the Dec 6 - 8 period. Cold first half of Dec all but guaranteed. Will there be some trackable events to coincide - to be determined. Peak cold looks next weekend. 2 Link to comment Share on other sites More sharing options...

(The National Weather Summary) (Storm Data) 1991:A tornado struck southeast Springfield, Missouri, causing F4 damage. Shortly after touchdown, the tornado reached F3 intensity, approximately 3 miles north of the town of Nixa.

We should see highs only in the 30s Friday into next weekend, which is well below normal. I just hope we get a little snow out of this cold pattern eventually. 1 Link to comment Share on other sites More sharing options...
