    There are three notable exceptions for the New York City area where 100° heat returned: 1949, 1953, and 1955.

    A short but severe heatwave will continue to scorch the region into the start of the weekend. Through 5 pm, highs included: Albany: 95° Allentown: 101° Atlantic City: 103° (old record: 100°, 1966) Baltimore: 101° Bangor: 93° (tied record set in 1941) Boston: 101° (old record: 98°, 1963) Bridgeport: 98° Burlington: 96° Caribou: 91° (tied record set in 2014) Concord: 97° Harrisburg: 102° Hartford: 100° (old record: 99°, 1966) Islip: 96° Manchester: 97° (old record: 95°, 1968) New Brunswick: 104° New York City-Central Park: 100° (tied record set in 1966) New York City-JFK Airport: 102° (old record: 101°, 1966) New York City-LaGuardia Airport: 104° (old record: 101°, 2016) Newark: 105° (old record: 103°, 1901) Philadelphia: 103° (tied record set in 1901) Portland: 96° Poughkeepsie: 103° (old record: 97°, 1966) Providence: 99° (old record: 98°, 1941) Raleigh: 98° Reading: 102° (tied record set in 1966) Richmond: 96° Scranton: 98° (tied record set in 1901 and tied in 1966) Sterling: 98° (tied record set in 1966) Trenton: 101° (tied record set in 1901) Washington, DC: 102° (old record: 101°, 1898) White Plains: 98° (old record: 97°, 1968) Wilmington, DE: 103° (old record: 98°, 1941 and 1966) Worcester: 94° Tomorrow will be another brutally hot day with the temperature peaking in the 100°-105° range. Some locally hotter temperatures are possible. Saturday will be a few degrees cooler, but still very hot. Some showers or thunderstorms are possible, especially late in the day. Sunday will turn a bit cooler with readings returning to near normal levels. Somewhat below normal readings with highs in the lower 80s are likely early next week. The ENSO Region 1+2 anomaly was +3.1°C and the Region 3.4 anomaly was +1.8°C for the week centered around June 24. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.60°C and the ENSO Region 3.4 anomaly has averaged +1.37°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -1.91 today. The preliminary Arctic Oscillation (AO) was +1.539 today.

    Both LaGuardia Airport and Newark hit 104° today.

    Newark has hit 104 while JFK topped out at 102.
  6. donsutherland1
    Newark: 104° (old record: 103°, 1901)
  7. donsutherland1
    Yes, the reading is from the Airport where it peaked at 103°.
  8. donsutherland1
    It did. Good catch.

    100°+ Highs as of 1:30 PM:
  10. donsutherland1
    As of 1 pm, the following areas have set new records: Atlantic City (101°); Poughkeepsie (99°), and Wilmington, DE (101°). The following locations have tied records: Manchester (95°) and Providence (98°). The following locations have also hit 100° and are approaching records: Harrisburg (100°), New York City-JFK Airport (100°), Newark (102°), and Philadelphia (100°). Central Park has reported a high of 98° so far. The statistical model (r2=0.941) based on the pre-tree overgrowth period has an implied 101° reading there.
  11. donsutherland1
    Atlantic City has recently reached 100°. That ties its daily record from 1966.
  12. donsutherland1
    Wilmington, DE has reached 98°. That ties the daily record that was set in 1941 and tied in 1966.
  13. donsutherland1
    Such ridges are uncommon in the Eastern U.S. No disagreement on the location of such a ridge.

    Unfortunately, that sensor is too close to the building. It's probably just 15-20 feet from the building. In general, its distance should be 4X the building's height.
  15. donsutherland1
    It reached 100° at 11 am, on July 22, 2011. Here are the hourly readings up to the 108° all-time mark:

    Select record high minimum temperatures (if they hold up through 1 am EDT):

    For the U.S., one hasn't typically seen such heat domes during summers preceding strong/super El Niño events. Such events have been far more common in Europe and Asia. However, during 2015 (Pacific Northwest) and 2023 (July-August in the Southwest/South Central) such domes appeared. Whether these recent events suggest that things are changing in the warming climate (especially more expansive marine heatwaves) remains to be seen. A sample size of two is too small to draw firm conclusions.
  18. donsutherland1
    Yes it did. It was a very impressive start to the heatwave there.
  19. donsutherland1
    Select records from today. The heatwave will intensify tomorrow.

    A short but severe heatwave will engulf the region into the start of the weekend. Already, parts of the region have experienced temperatures in the 90s. Through 5 pm, highs included: Albany: 94° Allentown: 97° Baltimore: 97° Boston: 92° Burlington: 93° Cleveland: 97° (old record: 95°, 1941 and 2002) Concord: 95° Detroit: 97° Harrisburg: 99° Hartford: 95° New York City: 93° Newark: 99° Philadelphia: 96° Poughkeepsie: 98° Reading: 99° Sterling: 97° (old record: 96°, 2012) Toledo: 99° (old record: 98°, 1931) Toronto: 97° Washington, DC: 96° White Plains: 93° Wilmington, DE: 96° At its height, the heat could rival that of early July 1966. Much of the region will likely experience its highest temperatures so this summer with maximum temperatures peaking in the 100°-105° range. Some locally hotter temperatures are possible. Most of the Mid-Atlantic and southern New England areas will see temperatures reach 100° or above during the height of the heatwave. Boston, Burlington, Philadelphia and Washington, DC could challenge their all-time records. The ENSO Region 1+2 anomaly was +3.1°C and the Region 3.4 anomaly was +1.8°C for the week centered around June 24. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.60°C and the ENSO Region 3.4 anomaly has averaged +1.37°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was +1.11 today. The preliminary Arctic Oscillation (AO) was +1.312 today.

    Dulles Airport has reached 96°. That ties its daily record from 2012. Many more records will fall in coming days in the Mid-Atlantic region.

    Given NCEI's and the Central Park Conservatory's choice to permit tree overgrowth to persist at Central Park's ASOS, I've run the statistical model to see what Central Park's highest annual temperatures might have been had the statistical relationships to the 30-year period preceding the tree growth persisted (proxy for pre-tree readings). The estimated 102° reading in June 2025 would have set a new monthly mark. During 2015-2026, Central Park would likely have seen four to as many seven 100° readings. 2021 and 2025 had the highest likelihood that Central Park would have recorded one or more 100° or above readings. In an increasing number of cases, Central Park's reported highest temperature falls more than 1 standard deviation below the statistical estimate.

    June 2026 ended with a monthly mean temperature of 73.4° in New York City. That was 1.4° above normal. Additional Notes: 1) Central Park's highest temperature was likely 97° on June 11-12 based on a statistical regression equation to compensate for tree overgrowth. 2) JFK Airport had an average high of 81.7° compared to Central Park's 81.4°. This is the largest margin by which JFK Airport's average June high was greater than Central Park's. The previous record and only such occurrence was in 2015 when JFK Airport's average high temperature was 0.03° higher than Central Park's mean high.

    I'm glad he's on his way to recovering. What a shock, especially at his age.
