bluewave Posted September 25, 2021 Share Posted September 25, 2021 It looks like NYC may finally drop below 55° next week. HPN could also see the first 40s of the fall.

CIK62 Posted September 26, 2021 Share Posted September 26, 2021 What is going on here on the EURO? The area that is hanging back from SAM 'hangs on' for at least 72 hours of 40mph gusts{from N} near here, starting at 168hrs.(not shown) The GFS and CMC have this is in a minor way only. 1 Link to comment Share on other sites More sharing options...
donsutherland1 Posted September 26, 2021 Share Posted September 26, 2021 Tomorrow and Monday will be fair and pleasantly warm days. Afterward, a cold front could bring some showers or thundershowers to the region on Tuesday. The MJO had recently been locked in Phase 3 at a high amplitude, frequently in excess of 1.500. Only 2006 and 2009 saw the MJO in Phase 3 at an amplitude of 1.500 or above for 2 or more days during September 10-20. Both years saw September end with a cold shot that continued into the first days of October. Both days saw Central Park's temperature fall to 49° on September 30. The guidance has now come into better agreement concerning a cool shot to end the month. Afterward, in the MJO cases, a fairly sharp rebound in temperatures followed. October wound up wetter than normal with 7.07" rainfall in 2006 and 5.58" of rainfall in 2009. Normal rainfall (1991-2020) is 4.38". 2021 remains on course to become the 6th out of the last 7 years during which September has had a mean temperature of 70° or above in New York City. Prior to 2000, New York City saw such warmth on average once every five years. In short, September has become more an extension of summer than a gateway to autumn in the New York City area. There is increasing consensus on the long-range guidance that October will be an unseasonably warm month. The first half could feature much above normal readings in the Northern Plains into Central Canada. Fall 2021 will likely be wetter to much wetter than normal in the northern Middle Atlantic region. Since 1869, there have been 9 August cases where New York City picked up 20.00" or more rainfall during the summer. Two thirds of those cases (and 4/5 of those with summer mean temperatures of 73.0° or above) had 17.00" or more fall precipitation in New York City. 2011 is probably the closest match in terms of precipitation and a nearly identical summer mean temperature. Mean fall precipitation for those 9 cases was 14.86". The median was 17.35". The 1991-2020 normal value is 12.27". The ENSO Region 1+2 anomaly was +0.2°C and the Region 3.4 anomaly was -0.4°C for the week centered around September 15. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.03°C and the ENSO Region 3.4 anomaly has averaged -0.45°C. Neutral ENSO conditions will likely prevail through September. Afterward, La Niña conditions could begin to develop. The SOI was -15.92 today. The preliminary Arctic Oscillation (AO) figure was +0.142 today. On September 23 the MJO was in Phase 4 at an amplitude of 0.946 (RMM). The September 22-adjusted amplitude was 1.305 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied 89% probability that New York City will have a warmer than normal September (1991-2020 normal). September will likely finish with a mean temperature near 70.4° (1.2° above normal). 4 Link to comment Share on other sites More sharing options...

We'll see. Probably correct. I still think modeling is separating streams. I think by tomorrow morning we'll know if the dry quiet is correct. Right now, I'm unconvinced. 1 Link to comment Share on other sites More sharing options...

donsutherland1 Posted September 26, 2021 Share Posted September 26, 2021 Morning thoughts… Today will be mostly sunny and pleasantly warm. High temperatures will likely reach the lower and middle 70s in most of the region. Likely high temperatures around the region include: New York City (Central Park): 73° Newark: 77° Philadelphia: 75° Normals: New York City: 30-Year: 72.3°; 15-Year: 73.5° Newark: 30-Year: 73.8°; 15-Year: 75.2° Philadelphia: 30-Year: 75.1°; 15-Year: 76.3° Tomorrow will be a very warm day.

SACRUS Posted September 26, 2021 Share Posted September 26, 2021 52 last night after a high of 80 yesterday. On the way to mid/upper 70s. Mon (9/27) and Tue (9/28) look like the warmest for potentially (the year) with highs 80/ low 80s in the warmer spots. Not to say it wont warm up which it looks likely by Oct 6, but dont think we exceed Mon/Tue maxes till spring. Front come sthrough Tue later so clouds could spoil the warmest readings on Tuesday. ECM / GFS cutt ULL ville 9/29 and on but keep the brunt of the rain north of the area. Cooler shot by Thu (9/30) - Sun (10/3) as ULL pulls down N/NNW flow. Once we clear the ULL towards the first full week of Oct, ridging looks to rebuild into the east and warm things up. GFS would have California style weather (overall) the next 10 days but I suspect we see clouds and rain chances with the ULL and stalled up pattern evolve.

donsutherland1 Posted September 26, 2021 Share Posted September 26, 2021 Tomorrow will be mostly sunny and unseasonably warm. Temperatures will likely reach the upper 70s and lower 80s. Tuesday will also be warm, but a cold front will push across the region overnight bringing some showers and perhaps thundershowers to parts of the region.
