Updated 90 degree days by season 2010 - prsnt

The issue with central park is it being a mecca for the NYC region as a whole and the perception isnt truly representative of the urban/city metro areas. Head lines first 100 possible since 2012, first 90 degree day , hottest in years when many other sites have been hotter recently and have 90 degree days already this year. TTN seems to be running lower than prior years but i havent looked to deep into it.

Records: Highs: EWR: 100 (2024) NYC: 97 (1988) LGA: 98 (2012) JFK: 97 (2012) Lows: EWR: 46 (1940) NYC: 49 (1897) LGA: 53 (1940) JFK: 56 (1968) Historical: 1886: TA destructive hurricane hit the Apalachicola – Tallahassee area of Florida on the summer solstice. Extensive damage was done in Florida and throughout the southeast by this storm. Damage was due mainly to extremely high tides. (Ref. Wilson Wx. History) 1893 - On the first day of summer the temperature at Dodge City, KS, soared to 106 degrees during the midst of a blistering heat wave. The heat wave initiated a severe three year drought in the Central Plains Region. Ironically, at about the same time, heavy rains in the Mississippi Valley were causing the river to swell to its highest level of record at New Orleans, LA. (David Ludlum) (The Weather Channel) 1919 - Seven heavy coach cars of a moving train were picked up and thrown from the tracks by tornado winds. A baggage car was set down thirty feet away from the rest of the train. (The Weather Channel) 1923: The island of Nantucket off Cape Cod had its earliest 90 degree reading and the only one ever in June. (Ref. Wilson Wx. History) 1954 - A severe hailstorm struck Wichita KS and vicinity causing nine million dollars damage. (The Weather Channel) 1968: A line of severe thunderstorms raced across the state of South Dakota at 60 mph with winds that exceeded 100 mph in some areas with winds over 60 mph quite common. Many areas also received extensive hail damage with dime to golf ball size hail common and even a few areas were pounded with baseball size hail. At least, nine tornadoes and 11 separate funnel clouds were reported, although more likely occurred...they were probably obscured by darkness in the east and by blowing dust in the west. To that point in the state's history, the night's storms were likely the most damaging on record as they resulted in $10 to $15 million dollars in damage. (Ref. Wilson Wx. History) 1972 - Phoenix, AZ, was drenched with 1.64 inches of rain late on the 21st and early on the 22nd to easily surpass their previous June rainfall record of 0.95 inches. The total for the month was 1.70 inches. (The Weather Channel) 1972: When Hurricane Agnes dropped 16 inches of rain over central Virginia in 1972, the James River flooded Richmond. Flood waters in the river reached 6.5 feet higher than the historical 200-year-old record. Richmond, VA experienced its worst flood of record as rains from Hurricane Agnes pushed the water level at the city locks to a height of 36.5 feet, easily topping the previous record of thirty feet set in 1771. Thirteen years later, a multi-million dollar floodwall was erected to prevent the rising waters of the river from overflowing again. Agnes gave DC. 7.19 inches rain in 24 hrs. an all-time rec. 11 inches n. suburbs, 15.00 in Herndon, 16 in Chantilly, VA. 1987 - A tornado destroyed 57 mobile homes at the Chateam Estates trailer park northwest of Detroit, MI, killing one person and injuring six others. Total damage was estimated at 1.7 million dollars. Thunderstorms over Lower Michigan also drenched the Saginaw Valley with up to 4.5 inches of rain in less than six hours. (The National Weather Summary) (Storm Data) 1988 - The first full day of summer was a torrid one, with afternoon highs of 100 degrees or above reported from the Northern and Central Plains to the Ohio Valley. Sixty-nine cities in the north central U.S. reported record high temperatures for the date. The high of 110 degrees at Sioux Falls, SD, was an all-time record for that location. Highs of 103 degrees at Des Moines, IA, 102 degrees at Fort Wayne, IN, 109 degrees at Huron, SD, 108 degrees at Sioux City, IA, and 101 degrees at South Bend IN were records for June. (The National Weather Summary) 1989 - The first day of summer heralded snow in the northern and central Rockies. In Colorado, 15 inches of snow was reported at the summit of Mount Evans and, in Wyoming, 18 inches was reported at Dickensen Park, west of Lander. Heavy rain continued in the eastern U.S. Huntsville, AL, reported a record 11.65 inches for the month, compared to the 0.17 inch rainfall total in June 1988. (The National Weather Summary) (Storm Data) 2005 - A slow-moving thunderstorm dumped up to a foot of hail in southeastern portions of Colorado Springs, Colorado. Snowplows had to be used to clear a route through a major thoroughfare in the city. Heavy rainfall from the storm left up to 4 feet of water in city streets, trapping dozens of motorists (Associated Press).
