CIK62 Posted September 30, 2020 Share Posted September 30, 2020 The last day of September is averaging 69degs. Making it 66degs., or +1.5. [[The first 7 days of October are averaging 65degs, making it 60degs., or -3.0]] Month to date is +0.7[68.9]. September should end at +0.8[68.8]. Remember my 1968 Almanac had a 30-Year Normal of 68.5 back then---it caught the Dirty 30's---in that. September has LOST 0.5 degree because of global warming?! 63*(97%RH) here at 6am, streets wet, mean looking overcast with breaks. 61*(91%RH) by 9am, breezy and clearing up. 67*(RH62%). by 2pm. 71*(53%) by 4pm.

donsutherland1 Posted September 30, 2020 Share Posted September 30, 2020 Morning thoughts... A storm that moved along an advancing cold front brought a soaking rain to much of the region into early this morning. Rainfall totals through 8 am included: Allentown: 1.49" Bridgeport: 0.85" Islip: 0.39" New York City: 1.61" Newark: 1.48" Philadelphia: 2.13" Poughkeepsie: 2.54" Scranton: 1.37" White Plains: 1.55" As the storm pulls away, clouds will give way to sunshine. Temperatures will likely reach the upper 60s and lower 70s across the region. Likely afternoon high temperatures around the region include: New York City (Central Park): 69° Newark: 71° Philadelphia: 70° The first week of October will likely be cooler than normal.

donsutherland1 Posted September 30, 2020 Share Posted September 30, 2020 New York City is concluding September with a monthly mean temperature of 68.8° (0.8° above normal). A somewhat warmer than normal October lies ahead, with the second half of the month likely to be warmer relative to normal than the first half. Phoenix recorded just its 13th September on record with a mean temperature of 90° or above with a monthly mean temperature of 91.5°. That made September 2020 the 3rd warmest September on record. Phoenix also registered its hottest June-September period on record with a four-month mean temperature of 95.4°. The previous record was 93.9°, which was set in 2011. The June-September 2020 figure also exceeded the previous summer (June-August) record of 95.1°, which was set in 2013 and tied in 2015. Climate change contributed to this most recent heat event. Climate change has increased the frequency, magnitude, and duration of extreme heat events in the United States and worldwide. Further increases are likely in coming decades as the world's climate continues to warm (for more information, refer to the links in the note below this discussion). The opening week of October will see generally cooler than normal conditions. No exceptional cold is likely. Warmer readings could return during the following week, though a renewed push of cool air remains possible. The latest EPS weeklies favor the development of a sustained warmer than normal pattern for the second half of October. The development of this warmth also shows up on the 63-ensemble MME subseasonal guidance and latest weekly CFSv2 guidance. Overall, October will likely be somewhat warmer than normal in much of the region with temperatures generally 0.5° - 1.5° above normal. October could also be wetter than September in and around the New York City area. Since 1950, 10 of the 12 (83%) of the La Niña cases that followed an El Niño winter saw October receive more precipitation than September, including 7 of the 8 (88%) cases since 1980. October 1954 and October 1998 were the exceptions. The largest increase in precipitation occurred in 2005. September 2005 saw just 0.48" precipitation in New York City. October 2005 received 16.73" precipitation. The ENSO Region 1+2 anomaly was -0.8°C and the Region 3.4 anomaly was -1.0°C for the week centered around September 23. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.92°C and the ENSO Region 3.4 anomaly has averaged -0.87°C. La Niña conditions will likely prevail into at least the start of winter. The SOI was +16.11. Today, the preliminary Arctic Oscillation (AO) figure was -1.039. On September 29 the MJO was in Phase 5 at an amplitude of 1.555 (RMM). The September 28-adjusted amplitude was 1.498. 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.

bluewave Posted October 1, 2020 Share Posted October 1, 2020 Steadily rising September temperatures brought the recent 10 year period to a 70.3° average in NYC. September has shown the fastest monthly temperature rise for much of the East. So expect a significant monthly average temperature increase when the new 30 year climate normals come out.
