Bingo! It could always be worse, even for the fine folk on LI. Could be up in Maine where this recent type of weather usually lasts until June and only 2 months later starts to get cool again, at least at night, in September. 1 Link to comment Share on other sites More sharing options...

dWave Posted May 16, 2019 Share Posted May 16, 2019 Unlike many previous warm days today held on to the warmth all day into the evening. It's not 10 degrees below the high temp by 5pm and falling for once. 1 Link to comment Share on other sites More sharing options...

I have been there on Memorial Day and been able to swim in a lake ( albeit a bit cold ) and I have been there when it was downright frigid.....2012 or 13 was like that, and in snowed in upstate NYC IIRC, or somewhere up there...

donsutherland1 Posted May 17, 2019 Share Posted May 17, 2019 Tomorrow through Monday, temperatures will likely be above normal across the Middle Atlantic and southern New England regions. Sunday and Monday could see the mercury approach or reach 90° as far north as Washington, DC. The ENSO Region 1+2 anomaly was 0.1°C and the Region 3.4 anomaly was +0.5°C for the week centered around May 8. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.12°C and the ENSO Region 3.4 anomaly has averaged +0.82°C. Conditions consistent with El Niño appear likely to persist through May in Region 3.4. However, some fluctuation to warm neutral conditions is possible for at least some time. The SOI was +2.78 today. Today's preliminary value of the Arctic Oscillation (AO) was -1.669. Periods when the AO has been at or below -1.500 during the first 10 days of May have typically coincided with readings that are 1.0°-2.5° below normal during the May 11-20 period. The average temperature during the May 11-20, 1981-2010 period was 62.3°. Previously, the modeled figure was as low as 57.3°, which was below what is typical during such patterns and implied a sharper rebound in temperatures toward the end of the period than shown on the guidance. Since then, the guidance has shifted in that direction. It continues to show temperatures reaching the upper 70s as far north as the northern Mid-Atlantic region in the latter part of the May 11-20 period. The possibility of an 80° or above temperature in the northern Mid-Atlantic and possibly southern New England during the latter part of this period has increased on the guidance. On May 15, the MJO was in Phase 8 at an amplitude of 1.769 (RMM). The amplitude was somewhat lower than the May 14-adjusted figure of 1.813. During the May 5-15 period, the MJO reached Phase 7 with an amplitude of 2.000 or above on two days. Since 1974, three years saw the MJO in Phase 7 with an amplitude of 2.000 or above during that same timeframe. The mean May 21-31 temperature was 67.9°. The warmest was 2011 with a mean temperature of 71.2°. However, the ENSO Region 1+2 anomaly averaged +0.62°C during May. The coldest was 1996 with a mean temperature of 64.5°. Then, the ENSO Region 1+2 anomaly averaged -1.31°C. During the last 6 weeks, the ENSO Region 1+2 anomaly has averaged +0.12°C. Therefore, the kind of chill that was seen in 1996 appears unlikely. At present, the guidance suggests a mean temperature of 68.2° for the May 21-31 timeframe, but that could be low. In addition, all three cases saw monthly high temperatures in the upper 80s or above in the northern Middle Atlantic region and middle and upper 80s or above in southern New England. The core of the warm anomalies during the May 21-31 period could be focused over the Southeast. Already, Atlanta has a mean temperature of 71.9° through the first 16 days this month. That ties 2019 with 1952 and 2012 as Atlanta's 19th warmest May 1-16 period on record. Atlanta could approach or exceed the all-time monthly record high mean temperature of 74.8°, which was set in 1996 and tied in 2018. Overall, the sensitivity analysis applied to the latest guidance suggests that the implied probability of a warmer than normal May in New York City is now 55%.

The Southeast and portions of the Mid-Atlantic will make a run on their warmest May. One of the strongest battles between the SE Ridge and 50/50 vortex on record for May. Atlanta stands a pretty good chance at surpassing its warmest May on record. Next week could see several days where Atlanta challenges or even sets new daily record high temperatures.

Slightly ot but I wonder if temperate rainforest is what our region is transitioning to with our climate becoming warmer/wetter over the long-term.

donsutherland1 Posted May 17, 2019 Share Posted May 17, 2019 The 80° isotherm came just south of New York City today. High temperatures just south of the City included: Atlantic City: 83°; Newark: 80°; and, Philadelphia: 82°. Temperatures will likely be above normal across the Middle Atlantic and southern New England regions during the weekend and into early next week. Sunday and Monday could see the mercury approach or reach 90° as far north as Washington, DC. Readings could reach the 80s even into New York City and its suburbs on Monday. The ENSO Region 1+2 anomaly was 0.1°C and the Region 3.4 anomaly was +0.5°C for the week centered around May 8. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.12°C and the ENSO Region 3.4 anomaly has averaged +0.82°C. Conditions consistent with El Niño appear likely to persist through May in Region 3.4. However, some fluctuation to warm neutral conditions is possible for at least some time.

The implied probability of May 2019's setting a new record high mean temperature for May is 52%. Select Statistics for Atlanta: Mean Temperature (May 1-17): 72.2° (16th warmest) Estimated Final May 2019 Average: 75.0° Warmest May on Record: 74.8°, 1996 and 2018 Finally, the sensitivity analysis applied to the latest guidance suggests that the implied probability of a warmer than normal May in New York City is now 51%. 1 Link to comment Share on other sites More sharing options...
uncle W Posted May 18, 2019 Share Posted May 18, 2019 I heard some people talking about how we go from winter to Summer with no Spring now...I think it's because of short memories...tomorrows highest temperatures came a week after some cold May days... record max... 90 in 1906...on 5/10 the max was 52 and the min 44... 90 in 1936...on 5/15 the min was 44...it was in the 90's before that earlier in the month... 89 in 1962...on 5/8 the max was 49 and the min 43...42 on 5/9... 88 in 1877...0n 5/11 it was 42 on 5/11...50/43 on 5/10... 88 in 1977...on 5/9 the max/min was 44/36 with wet snow and rain... 1 Link to comment Share on other sites More sharing options...
