Then temperatures quickly warm across the US to start November. 3-4" of rain on Friday? (any wind potential there?) and then mid 30s for lows over the weekend, followed by a big warm up next week? Are we looking at 70s with sunshine? Link to comment Share on other sites More sharing options...

Timing-merger of the northern and southern streams late this week is imo, pretty uncertain, with vastly different storm tracking-precip shields. No action on my part for a topic, prior to 6PM tonight at the earliest. Just need a little more consensus. Walt, is it actually the remnants of Zeta that will cause the snow N/W of the city? And any wind potential with that? Also, I have been hearing there is more TC potential after Zeta? Link to comment Share on other sites More sharing options...

Car thermometer got up to 75, which was the highest temp reading between Long Island and southern Virginia. Lowest was 66 just north of Richmond, temp shot up to 73 in the UHI. Fall foliage in Central Jersey and even swaths of South Jersey and Delaware is further along than in NYC and Long Island, shockingly. Maryland outside of Baltimore and DC looked like NYC/LI. That sounds about right to me. NYC usually lags behind, then the foilage starts to really ramp up headed to Halloween, peaking in early Nov. The UHI ends up with shorter window to see real fall colors 1 Link to comment Share on other sites More sharing options...
donsutherland1 Posted October 26, 2020 Share Posted October 26, 2020 Temperatures rose only into the lower 50s today in much of the region. Overnight and tomorrow, it will be mainly cloudy with some showers. Readings should return to the upper 50s to perhaps the lower 60s. The remainder of the closing week of October will likely see temperatures average below normal courtesy of a cold close to the month. Out West, select low temperatures through 8 pm EDT included: Billings: 5° (old record: 18°, 1997) Casper: 5° (old record: 13°, 1997) Cheyenne: 5° (tied record set in 1873) Cut Bank, MT: -10° Denver: 11° Great Falls: 0° Helena: 3° Missoula, MT: -7° (old record: 10°, 1919) ***New Monthly Record*** Rapid City: 11° A storm will likely bring a significant snowfall to parts of Colorado, New Mexico, Oklahoma, Wyoming, and perhaps even portions of the Texas Panhandle tomorrow into Tuesday. As that storm heads eastward, Zeta will very likely make landfall along the U.S. Gulf Coast by midweek. As a result, late Thursday through Friday could see a potentially significant precipitation event in the region. The potential exists that cold air from eastern Canada could be drawn southward to produce at least some snowfall in an area running from northern Pennsylvania, across central New York State, and into central New England. Behind the storm, the coldest air of the season will briefly push into the region. November could commence on a cool note. A prolonged period of above normal temperatures could develop during the second week of November. The ENSO Region 1+2 anomaly was -1.2°C and the Region 3.4 anomaly was -1.4°C for the week centered around October 14. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.85°C and the ENSO Region 3.4 anomaly has averaged -1.10°C. La Niña conditions will likely prevail at least into mid-winter. The SOI was -6.71. Today, the preliminary Arctic Oscillation (AO) figure was +0.752. On October 24 the MJO was in Phase 5 at an amplitude of 2.028 (RMM). The October 23-adjusted amplitude was 2.274. Since 1950, there have been five cases where a La Niña developed during June-July-August or afterward following an El Niño winter. 4/5 (80%) of those cases saw a predominant EPO+/AO+ winter pattern. The most recent such case was 2016-17. 9/10 (90%) of the La Niña winters that followed an El Niño winter featured a predominantly positive EPO. A predominant EPO+/AO+ pattern is likely for winter 2020-21. In response, it is likely that the Middle Atlantic and southern New England areas will see a warmer than normal winter with potentially below normal snowfall. Based on sensitivity analysis applied to the latest guidance, there is an implied 87% probability that New York City will have a warmer than normal October. October will likely finish with a mean temperature near 58.2°. Link to comment Share on other sites More sharing options...
CIK62 Posted October 26, 2020 Share Posted October 26, 2020 The GFS, after much deliberation with itself, has settled on 10 straight AN days to start November. The uncorrected average is 58degs., for the period. There is almost no precipitation for the period being indicated for us. November itself is looking AN everywhere in the US 48, with mostly linear flow from west to east. A dip in the flow over southeast Canada, making for AN Trough, might keep us closer to Normal than the rest of country. Another boring '30' to endure?

CIK62 Posted October 26, 2020 Share Posted October 26, 2020 The last 6 days of October are averaging 53degs. Making it 49degs., or about -3.0. Month to date is: 59.9[+2.1]. October should end near 57.8degs., or about +1.0. 53*(93%RH) here at 6am, streets wet, foggy look, about 1mile. 59*(95%RH) by Noon. EURO/GFS have about 2" through next Monday. GEM has 3" and some sub-freezing lows here to end month. btw: In two short runs of the GFS, it has gone from 10 straight days in the 60's (as I noted late yesterday) to start November, to only 3. Tropics: 18.6N 84.3W., 56.2N 38.5W--stretched out--headed for Europe. 1 Link to comment Share on other sites More sharing options...

donsutherland1 Posted October 26, 2020 Share Posted October 26, 2020 Morning thoughts... Today mostly cloudy with some drizzle and scattered showers. It will be milder than yesterday. Temperatures will likely reach the upper 50s and lower 60s across the region. Likely high temperatures around the region include: New York City (Central Park): 59° Newark: 61° Philadelphia: 65° A significant precipitation event followed by a brief shot of sharply colder air is likely toward the end of the week. Out West, winterlike weather prevailed. Cheyenne picked up 14.0" snow. That broke the daily record of 5.7", which was set in 2011 and the October daily record of 8.9", which was set on October 22, 1906. Record cold also prevailed in numerous locations including: Bozeman, MT: -18° (old record: 11°, 2002) Butte, MT: -18° (old record: 9°, 2002) Casper: -7° (old record: 12°, 2002) Cody, WY: -7° (old record: 5°, 1919) Missoula, MT: -3° (old record: 15°, 2002) Salt Lake City: 20° (old record: 22°, 1878) Sheridan, WY: -10° (old record: 5°, 1913) Link to comment Share on other sites More sharing options...

LibertyBell Posted October 26, 2020 Share Posted October 26, 2020 I cant remember the last time before May 2020 that we had a T of snow in May. And if we do get a T of snow in October, that'll be the first time since 2011 I think? 2014-15 feels like an underrated winter, because that was excellent for both snow and cold in the second half. March 2018 was a lot better at ISP than it was in NYC (and western Nassau for that matter). Wow, ISP had 16" of snow in the April 1982 blizzard- or was that a combo of two storms? If it was just from the blizzard, they doubled our totals on Western Long Island- I wonder why? Everyone was cold enough for a lot of snow.

The remainder of the closing week of October will likely see temperatures average below normal courtesy of a cold close to the month. Out west, numerous daily record low temperatures were set.
