donsutherland1 Posted Monday at 02:07 PM Share Posted Monday at 02:07 PM As an extreme air mass is poised to set temperature records across the New York City Metro Area during July 1-3, it is again worth noting that the strong cooling effect of Central Park's overgrowth of trees will make it exceedingly difficult for Central Park to reach 100°. It is likely that JFK Airport, LaGuardia Airport, Newark, and possibly Bridgeport, Islip, and White Plains could all reach 100°. Much of the region will see the heat peak at 100°-105°. Last June, the New York City area experienced its highest June monthly temperatures on record. JFK Airport topped out at 102° (old record: 99°, 1952, 1959, and 1964). LaGuardia Airport reached 101°, tying the mark set in 1952 and tied in 2017). Newark reached 103° (tying the record set in 2021). Bridgeport reached 97° (tying the record set in 2008). Islip topped out at 101° (demolishing the old mark of 96° from 1966 and 1994). White Plains reached 98° (tying the record set in 1952 and tied in 1953). A shaded Central Park reached just 99°. Based on a statistical regression equation (coefficient of determination: 0.941), for the 30-year period preceding the excessive tree growth (1966-1995), Central Park actually hit 100° on two days. Its peak temperature would have been 102° on June 24th, also setting a new monthly record (old record: 101°, 1934 and 1966). For good reason, homogenization is applied to long-term records to account for changes such as the tree growth that has been permitted to dampen Central Park's summer high temperatures. IMO, homogenization should be applied on a daily basis, given the persistent lack of interest in addressing the documented problem (as noted on NOAA's climate site inventory). How has tree growth affected Central Park? Even as average high temperatures during Summer (June, July, and August) have increased at JFK Airport and LaGuardia Airport during 1961-1990 to 1991-2020, they have decreased at Central Park. June Mean High Temperatures: July Mean High Temperatures: August Mean High Temperatures: Through June 28th, Central Park's mean June temperature is running 0.5° below that of JFK Airport, even as JFK is affected by the sea breeze. Only 2015 (0.03° margin) had a warmer mean June high at JFK airport. To date, Central Park's highest monthly temperature is 91°. Here's how it compares with the other sites in the New York City area: Bridgeport: 91°; Islip: 94°; JFK Airport: 96°; LaGuardia Airport: 98°; Newark: 97°; and, White Plains: 92°. Based on the statistical assessment, Central Park's monthly high is likely 97° (June 11-12). In terms of 90° or above days, Central Park stands at 2 days in June. Here's how that compares with the other sites in the New York City area: Bridgeport: 1 day; Islip: 2 days; JFK Airport: 2 days; LaGuardia Airport: 6 days; Newark: 7 days; and, White Plains: 2 days. The statistical estimate suggests 4-6 days are likely to have occurred this month. 1 Link to comment Share on other sites More sharing options...

cannoliman42 Posted Monday at 04:23 PM Share Posted Monday at 04:23 PM 12z GFS not backing off the heat for Thursday and Friday. 104 in Central Park for Thursday, with some 106 readings near Newark, and 105 in Central Park on Friday, with some 106 readings in northern Manhattan/Hudson County. At least humidity will be minimal. 1 1 Link to comment Share on other sites More sharing options...

The prolonged drought and peak sun will help a lot too. I'd be surprised if at least a couple places don't hit 105+ 1 Link to comment Share on other sites More sharing options...

FPizz Posted Monday at 10:23 PM Share Posted Monday at 10:23 PM What did the surface map from 1966 look like for Thursday and Friday for the US for when the majority of record highs for those days occurred around here? You guys are good for finding that stuff. Link to comment Share on other sites More sharing options...

I remember water restrictions and people having wells dug in their back yards. I simple searched 1966 rainfall. For NYC, the summer was extremely dry. There may have been a tropical system involved in the September total, I just don’t recall. You need no correction, MANDA, about that summer. Stay well and hydrated.

bluewave Posted Tuesday at 11:18 AM Share Posted Tuesday at 11:18 AM The usual warm spots around the area have a shot at 104°-105° or warmer. Both the Euro and GFS have 850mb temperatures around +25 C Thursday and Friday. I believe July 2011 was the last time 850 mb temperatures reached this high. 2 Link to comment Share on other sites More sharing options...
