CIK62 Posted October 20, 2020 Share Posted October 20, 2020 Made it to 70* here by 4pm. GFS says 9 more of these, EURO says 6 more and the GEM 5 more. Model shortcomings will be appearing all winter because there will only be a few times when all forces are pulling in the same direction at the same time. Each model will latch on to a different operative and then exchange rolls with another model or even one of its own runs. Only experienced mets with a lot of luck are going to beat the models, despite the dismal track record that they will likely be accruing for themselves. This period was frustrating with a snow bearing TS that never formed, turning into a 70 Degree Day. Near the 26th, that is. Gonna look like the gaming floor in Las Vegas rather than NWS Headquarters. Excitement/Frustration awaits. 1 Link to comment Share on other sites More sharing options...

Not impossible for high terrain ice in the Catskills but that would be a really really really long shot, at this point. 1 Link to comment Share on other sites More sharing options...

Not really luck, it’s a pattern that sticks the trough in the west which occurs all the time in Ninas. 1 Link to comment Share on other sites More sharing options...
donsutherland1 Posted October 20, 2020 Share Posted October 20, 2020 This morning, the temperature fell to 10° at International Falls, which broke the previous daily record low figure of 12° from 1952. Toward the end of the week, another near-record to record cold air mass will likely be overspreading the Northern Plains. However, much of this cold air will likely remain confined well west of the region through much of the remainder of this month. Temperatures will likely remain mainly above normal through the remainder of the week in the Middle Atlantic and southern New England areas. One or more days could see much above normal temperatures. A brief shot of cooler air could arrive during the weekend. Toward the end of the month, cooler air could begin to spill into the region. 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 -1.48. Today, the preliminary Arctic Oscillation (AO) figure was -0.739. On October 19 the MJO was in Phase 5 at an amplitude of 2.391 (RMM). The October 18-adjusted amplitude was 2.407. 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. In addition, from the larger pool of La Niña winters following El Niño winters, there were four cases where October saw the MJO in Phases 4-6 for 20 days or more: 1983-84, 1988-89, 1998-99, and 2016-17. All four cases featured an EPO+/AO+ winter. Three cases saw the MJO in Phases 4-6 for less than 20 days: 1995-96: 12 days, 2007-08: 6 days, and 2010-11: 6 days. Both 1995-96 and 2010-11 featured a predominantly negative AO. The latest ensemble guidance favors October 2020 falling into the former pool. Moreover, among the former pool, both 1988-89 and 1998-99 saw the MJO in Phase 5 with an amplitude of 2.000 or above as has occurred this year. Both those winters featured below to much below normal snowfall in the Middle Atlantic and southern New England areas. Select snowfall seasonal snowfall totals were: 1988-89: Boston: 15.5" New York City: 8.1" Philadelphia: 11.2" 1998-99: Boston: 36.4" New York City: 12.7" Philadelphia: 12.5" None of this is cast in stone. However, this is a plausible scenario should things evolve toward an EPO+/AO+ winter as is suggested on some of the current seasonal guidance. Based on sensitivity analysis applied to the latest guidance, there is an implied 88% probability that New York City will have a warmer than normal October. October will likely finish with a mean temperature near 58.8°. 1 Link to comment Share on other sites More sharing options...

In 7 of the prior 10 cases when 2” or more snow fell on any day in October, Minneapolis wound up with normal or above normal snowfall.

For the most part, average or above. However, in the cases with the larger amounts, the East wound up with below normal snowfall. The sample size is too small to draw conclusions about the East, especially when one considers ENSO. Link to comment Share on other sites More sharing options...

donsutherland1 Posted October 21, 2020 Share Posted October 21, 2020 Morning thoughts... Clouds, fog and mist will give way to at least partial sunshine. It will be another mild day with readings mainly near or just above 70° in much of the region. Likely high temperatures around the region include: New York City (Central Park): 71° Newark: 74° Philadelphia: 75° Overall, warmer than normal conditions should prevail into the start of the weekend.
