Roger Smith Posted September 15, 2021 Share Posted September 15, 2021 With regard to that listing of 80 degree seasons at NYC, here's a breakdown of the 30-year averages. This shows both 1871-1900 and 1869-1900 which have the same averages within 0.1 (A), then 1901-30 (B), 1931-60 (C), 1961-90 (D) and 1991-2020 (E). The overall average of 152 seasons is also shown in bold type (F). The calendar dates shown are for non leap years, go one day earlier to apply to leap years. I derived an actual average duration (of 80 and + seasons) for all leap years and found that it was almost five days shorter (duration) than the overall data, so one would expect the actual leap year data set to have narrower extremes. However the sample size may account for that kind of internal variation in the data. 80 and + seasons ________________________________________ >80 seasons ____________________ _____________ A ______ B ____ C ____ D ____ E ____ F ________ A _____ B _____ C _____ D _____ E _____ F start date _ May 3 _ Apr 30 _ Apr 30 _ Apr 21 _ Apr 20 _ Apr 27 <<>>May 6 _ May 4 __ Apr 30 _ Apr 22 _ Apr 23 _ Apr 29 end date __ Sep 24 _Sep 30 _Oct 10 _ Oct 5 _ Sep 30 _ Oct 2 <<..>>Sep 19 _ Sep 28 _ Oct 7 __ Oct 3 __ Sep 26 _ Sep 28 duration ___ 143 __ 153 ___ 162 ___ 166 __ 162 __ 157 <<....>> _135 __ 146 ___ 159 ___ 163 __ 154 __ 151 __________________ Some interesting trends emerge from this. The season was getting longer until around the 1960s, but while the onset continued to advance or at least remain static, the end of these seasons began to pull back towards the earlier termination dates seen around the second interval 1901-30. My guess is that it won't continue to do that for 2021-50, but the phenomenon of record warmth in late autumn seems to have peaked around the 1960s while that of early spring warmth has shown a tendency to be more evenly distributed since about 1930. The differential between 80 and + and the >80 seasons was smaller when they lasted longer, and I noticed while compiling the table a tendency for quite a few years to end with a much higher reading than 80, a few actually ended their 80+ or >80 seasons with a 90 degree reading. By the way, the longest 90 deg season was way back in 1927 (first date Apr 20, 90F and last Oct 2, 90F). That was a season of 164 days. The second longest was 1939 (first May 7, 92F and last Oct 10, 91F). That season was 155 days. 2010 went from Apr 7 to Sep 9 but had an 89 deg reading on Sep 26. 1 1 Link to comment Share on other sites More sharing options...

We know what is going to happen before it starts It took a couple of decades to say this, but this is your new September weather: a slightly cooler August We are no longer transitioning to a new climate…We are in a new climate in the NYC area Hard to argue, but it's also hard to believe a global increase of 2 degrees since the 1880's can have such a profound effect. I certainly am ignorant of the "accumulated heat" topic. I guess that may explain why such a seemingly small increase would result in extreme warmer temperatures in our area? 1 Link to comment Share on other sites More sharing options...

donsutherland1 Posted September 16, 2021 Share Posted September 16, 2021 A cold front will cross the region tonight with some showers and thundershowers. Its progression will slow resulting in a partly to mostly cloudy and cooler day tomorrow. Additional showers are possible in parts of the region. A warm September outcome remains on track. Despite a cooler than normal first 7-10 days (for example, the 9/1-7 anomaly was -2.5° in New York City and the 9/1-10 anomaly was -1.6° in New York City), September will likely feature near normal to somewhat warmer than normal temperatures in much of the region. The second half of the month could feature above to perhaps much above normal temperatures. As a result, 2021 is increasingly likely to become the 6th out of the last 7 years during which September has had a mean temperature of 70° or above in New York City. Prior to 2000, New York City saw such warmth on average once every five years. In short, September has become more an extension of summer than a gateway to autumn in the New York City area. 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". The ENSO Region 1+2 anomaly was -0.2°C and the Region 3.4 anomaly was -0.3°C for the week centered around September 8. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.22°C and the ENSO Region 3.4 anomaly has averaged -0.43°C. Neutral ENSO conditions will likely prevail through September. Afterward, La Niña conditions could begin to develop. The SOI was +10.34 today. The preliminary Arctic Oscillation (AO) figure was +0.141 today. On September 13 the MJO was in Phase 3 at an amplitude of 1.898 (RMM). The September 12-adjusted amplitude was 1.603 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied 76% probability that New York City will have a warmer than normal September (1991-2020 normal). September will likely finish with a mean temperature near 71.0° (1.8° above normal). 3 Link to comment Share on other sites More sharing options...

donsutherland1 Posted September 16, 2021 Share Posted September 16, 2021 Morning thoughts… Today will be mostly cloudy and cooler. Showers and perhaps thundershowers are possible in some areas. 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): 75° Newark: 79° Philadelphia: 80° Normals: New York City: 30-Year: 76.3°; 15-Year: 77.1° Newark: 30-Year: 77.8°; 15-Year: 78.6° Philadelphia: 30-Year: 79.0°; 15-Year: 79.7° Tomorrow will be partly to mostly cloudy. 1 Link to comment Share on other sites More sharing options...
CIK62 Posted September 16, 2021 Share Posted September 16, 2021 The next 8 days are averaging 75degs.(68/73), or +6. Month to date is 71.9[Normal] at its midpoint. Convienient. Could be 73.0[+2.1] by the 23rd. More likely 72.0[+1.1]. 74-78 today, e. wind, rain? late. EURO drops off by the 24th., but the GFS goes to the 29th, it seems. Reached 80 here yesterday. 72*(78%RH) here at 6am, some overcast. 77* by Noon. 77* at 3pm. 78* at 4pm. 76* at 6pm. Link to comment Share on other sites More sharing options...
