The problem is we have seen ultra persistent patterns in recent years. The question is how long this can hold. It’s not what we want to see. It really does feel like summer tonight! Just one of those early September nights! I 100% agree about this 3 month pattern persistence. It’s something we have been stuck in for years now. I remember last November it was 70 degrees to start the month. It was great for the late season stripe bass fishing. I’m completely okay with it being warm currently! I don’t want a ideal pattern for snow until mid December 1 Link to comment Share on other sites More sharing options...

This time the Pacific is very unfavorable. The -NAO blocking is also pressing pretty far south near New England. The source region continues to be from the pac with any trough we do get. Until that changes are cool downs will be brief and around normal 1 Link to comment Share on other sites More sharing options...

wdrag Posted October 20, 2021 Share Posted October 20, 2021 Not wintry but definitely signs that one of these troughs crossing the mid Atlantic coast between the 25th-30th is going to create an ocean nor'easter of 40-50kt... whether its' grazing Delmarva or LI? and with only a few 40 kt gusts or more vigorous on our coasts? Tides are not abnormally high so that is good. The previously posted 500MB height departures from normal show the blocking. 2 Link to comment Share on other sites More sharing options...
donsutherland1 Posted October 21, 2021 Share Posted October 21, 2021 Under bright sunshine, the temperature surged into the middle and upper 70s across much of the region. High temperatures included: Bridgeport: 77° (old record: 75°, 1953) Islip: 75° (old record: 74°, 1969, 1979, and 1984) New Haven: 77° (old record: 73°, 1953 and 2017) New York City-JFK: 79° New York City-LGA: 80° (old record: 79°, 1953 and 1984) New York City-NYC: 75° Newark: 80° (tied record set in 1947 and tied in 1969) Philadelphia: 76° White Plains: 74° Newark reached 70° for the 172nd time this year. As a result, 2021 is now has the 2nd most days on record. Today was also Newark's 116th 80° day, which ranks 2nd on the all-time list. Tomorrow and Friday will be unseasonably warm. Another cool shot is likely for the weekend. The MJO has now completed its passage through Phase 5 at a very high amplitude. During the 1991-2020 period, there were 6 cases with passage through Phase 5 with at least three days at an amplitude of 1.500 or above: 1998, 2000, 2004, 2010, 2017, and 2020. There was a strong signal for the second half of October to wind up warmer than normal (83%) cases in the New York City area. However, that signal broke down to a 50-50 split for the first 10 days of November. That hints at possible timing for a pattern transition depending on the pattern evolution and changes in the teleconnections. 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". Following very wet July-September periods, winter (December-February) precipitation has typically been near or below normal. The most recent exception was winter 2018-19. The ENSO Region 1+2 anomaly was -0.2°C and the Region 3.4 anomaly was -0.8°C for the week centered around October 13. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.15°C and the ENSO Region 3.4 anomaly has averaged -0.43°C. La Niña conditions will likely persist through at least mid-winter. The SOI was +6.70 today. The preliminary Arctic Oscillation (AO) figure was +0.151 today. On October 18 the MJO was in Phase 2 at an amplitude of 0.315 (RMM). The October 17-adjusted amplitude was 0.375 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied 98% probability that New York City will have a warmer than normal October (1991-2020 normal). October will likely finish with a mean temperature near 61.7° (3.8° above normal). Link to comment Share on other sites More sharing options...

LibertyBell Posted October 21, 2021 Share Posted October 21, 2021 8 hours ago, bluewave said: In the new era of stuck and stagnant weather patterns it has happened twice. The 13-14 ridiculously resilient ridge pattern started in October and continued into the winter. Fall 2016 featured the trough locking in near Seattle during September and running through the winter. Even though 16-17 had record winter warmth near 40°, we still had close to 40” of snow in spots for a 40/40 winter. The SE Ridge and Pacific Jet relaxed just enough at times for the -NAO /-AO intervals to produce. Even though it was in the 60s the day before the February blizzard. you only need the pattern to change for a few days to get a snowstorm.....so we had 40/40 both in 2015-16 and 2016-17? How close was 2005-06 to that? Link to comment Share on other sites More sharing options...

Rtd208 Posted October 21, 2021 Share Posted October 21, 2021 Mt. Holly's current take on next week. I would lean more towards the GFS Op but we'll see. .LONG TERM /SATURDAY THROUGH WEDNESDAY/... An upper level low will remain quasi-stationary near the Hudson Bay Saturday into Sunday before getting ejected east over the Canadian Maritimes. Mostly dry conditions are forecast Saturday into Sunday with highs in the low to mid 60s. The aforementioned wave in the short term discussion will cross the zones early Saturday, which may induce some shower development but chances look low here. Have kept chances of precipitation capped at slight chance. Either way, cloud cover will likely be more robust Saturday and Sunday. Late Sunday into Monday another wave crosses the Central Plains with surface cyclogenesis occurring over KS. The wave will then head east along the tightening baroclinic zone with chances of precipitation increasing from west to east Monday morning. Chances of precipitation will then continue into Tuesday as a psuedo Miller-B pattern tries to setup. The pattern here remains low predictability though as the GFS indicates wave breaking occurring with a deep vertically stacked area of low pressure developing by Wednesday. The ECMWF shows a much more progressive pattern. Taking a look at the latest EPS and GEFS runs, would indicate that the deterministic GFS deepens the low pressure far to much. The deterministic ECMWF solution appears to fit the overall ensemble envelope much more. && Link to comment Share on other sites More sharing options...

wdrag Posted October 21, 2021 Share Posted October 21, 2021 As per several prior notes from others: 00z/21 cycle modeling continues the risk of a pretty decent storm in the northeast next week (or two storms?). Additionally, should something get going along the w Mexican coast and approach the Gulf of CA ~26th, some of its moisture may get involved in the northeast USA storminess ~ the 30th. Something to keep an eye on. Not wintry but definitely signs that one of these troughs crossing the mid Atlantic coast between the 25th-30th is going to create an ocean nor'easter of 40-50kt... whether its' grazing Delmarva or LI? and with only a few 40 kt gusts or more vigorous on our coasts?

donsutherland1 Posted October 21, 2021 Share Posted October 21, 2021 Morning thoughts… It will partly to mostly sunny and unseasonably warm. High temperatures will likely reach the middle and upper 70s in most of the region. Likely high temperatures around the region include: New York City (Central Park): 74° Newark: 79° Philadelphia: 77° Normals: New York City: 30-Year: 62.6°; 15-Year: 63.2° Newark: 30-Year: 64.1°; 15-Year: 65.0° Philadelphia: 30-Year: 65.3°; 15-Year: 65.7° The warm weather will continue through tomorrow, but a cooler weekend lies ahead.

There is a high wind signal for parts of the area sometime next week and possibly svr as well. No thread yet but if these trends continue another day, will probably start one for damaging wind and spotty 4+ inches of rain in our subforum. Definitely will be active as compared to this week. 4 Link to comment Share on other sites More sharing options...
