donsutherland1 Posted September 1, 2020 Share Posted September 1, 2020 New York City's Central Park finished with a monthly mean temperature of 76.9° for August. Its summer mean temperature was also 76.9°, which tied summers 1949, 1983, and 1993 for the fourth warmest summer on record. Tomorrow will be mainly cloudy with showers and some periods of rain possible. Rainfall amounts will likely come to 0.25" or less for much of the region. Temperatures will be in the middle and upper 70s. Beyond midweek, temperatures will likely return to above normal levels. Afterward, a deep trough in Canada will move toward the Great Lakes Region and provide a period of cooler weather. Most of the colder air will stay west of the Appalachians. That trough may persist until near or just after mid-September. Nevertheless, the first half of September will likely wind up somewhat warmer than normal and September, as a whole, will likely finish warmer than normal (generally 1°-3° above normal). Parts of the Northeast and also Southwest recorded their warmest summer on record. At New York City's LaGuardia Airport, the summer mean temperature was 79.5°, which surpassed the prior record of 79.2° from 2010. Phoenix had, by far, its warmest summer on record. Phoenix concluded with a summer mean temperature of 96.7°. That smashed the previous record of 95.1°, which was set in summer 2013 and tied in summer 2015. August 2020 was surpassed July's record for the warmest month on record with a mean temperature of 99.0°. To date, Phoenix has smashed its record for most days with high temperatures of 110° or above (50), 115° or above (13), and low temperatures of 90° or above (28). More on Phoenix's historic summer can be found here: The ENSO Region 1+2 anomaly was -0.6°C and the Region 3.4 anomaly was -0.7°C for the week centered around August 26. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -1.02°C and the ENSO Region 3.4 anomaly has averaged -0.63°C. Neutral-cool conditions will likely evolve into La Niña conditions during the fall. The SOI was +21.36. Today, the preliminary Arctic Oscillation (AO) figure was -0.535. Daily MJO data remains unavailable. Since 1990, there have been 11 La Niña events, 6 of which followed an El Niño winter. 10/11 (91%) case saw warmer than normal September. All 6 following an El Niño winter were warmer than normal. September mean temperatures for New York City for those cases were: 11 cases: 69.9°; Subset of 6 cases: 70.8°; Entire 1990-2019 period: 69.0°. The September mean temperature for all La Niña and neutral-cool cases following an El Niño winter (1950-2019: n=13) was 69.9°. Overall, the evolution of ENSO, along with the observed ongoing monthly warming (1.6°/decade in NYC and 1.5°/decade in the Northeast Region during September 1990-2019), favors a warmer than normal September. 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. Finally, on August 30, Arctic sea ice extent was 3.995 million square kilometers (JAXA). 2020 will be the second consecutive year with a minimum figure below 4.000 million square kilometers and third time on record. The highest 25% bound is 3.768 million square kilometers. The lowest 25% bound is 3.589 million square kilometers. Link to comment Share on other sites More sharing options...

bluewave Posted September 1, 2020 Share Posted September 1, 2020 Several stations finished with August top 10 warmth. All our stations except Newark recorded a top 5 warmest summer. LGA established a new warmest summer on record. BDR tied for 1st with 2016 and ISP was a close 2nd to 2010. So numerous summers and summer months in the top 10 warmest just since 2010.

Don, odds that next summer NYC will have the kind of statistically anomalous summer that Phoenix had this summer? Link to comment Share on other sites More sharing options...
