Uneventful storm.  Looked promising.

Some stations in NJ just set their May monthly maximum high temperature when they reached 100°. In early July multiple stations were within a few degrees of their monthly max for July and all-time high.

Last June Baiting Hollow on Eastern LI reached 103° far from any urbanization and may have been the highest all-time temperature for that area. So all stations regardless of how urbanized they have been experiencing record heat. 

The drier pattern from the 1940s to early 2000s produced monthly maxes in August and September which haven’t been matched. Probably related to the early extreme summer heat in recent years turning wetter as we move into August and September. 

You will notice we had all-time record October heat as recently at 2019 in the mid 90s. That was the result of a flash drought which developed later in the season. 

February 2018 was probably our most extreme monthly max of any month reaching 80° for the first time at the areas away from the cooler ocean influence. A summer extreme of that magnitude would give the usual warm spots a reading in the 110° to 112° range.

 

I've started questioning the accuracy of stations on weather underground, even stations that were formerly reliable seem to have become less so. There's a Davis Vantage Pro 2 in Valley Stream, NY that has been in operation since the 1990s and has closely matched JFKs temperatures but in the last couple of years I've noticed an increasing variance with higher temperatures. In July 2011 it peaked at 102.0 which is fairly close to JFKs peak of 103. Last year in June it peaked at 104.6 when JFK hit 102 on consecutive days. This year it somehow reached 106.8 on one day, 104.7 on another day and 103.2 on the third day when JFKs highs were 102, 100 and 100. Although JFK had three straight days of triple digits to match the record from 1966 I didn't see the peak as being anywhere near as extreme as what 1966 was or even what happened in 2011 or last year for that matter. The Valley Stream weather station even recorded a high of 101.1 on that smoked filled day of July 15th when JFK hit 98. Without the smoke JFK would surely have hit 100 for an unprecedented fourth time but the smoke stopped that from happening and I think the Valley Stream Weather Station was off by a few degrees too. I wonder if these sensors get less accurate with time?

As far as records in October and February go it's definitely much easier to set monthly records at that time than it is to do it in July and August. I'm really not sure if a monthly max of 110 to 112 is possible in our area at the first order sites like EWR and LGA. Those records of 108 and 107 will likely stand for a long time, especially LGAs 107 from 1966. There's nothing even close to that there and EWRs 108 from 2011 also stands apart from the rest. I think the planet sets a natural ceiling for how high the extremes can be even as the averages keep going up, the difference between the min and max just becomes less as those values become compressed.

The was the massive Atlantic ridge >594 DM parked off the Atlantic all of last week a bit to east to bring the persistent mid 90s + and strong heat has been capped since the 14th of July in the area.  

Yes that was a massive ridge Tony but I wouldn't call that a heat dome. Based on past experience for a high to be a heat dome it has to be centered over land. A high centered over water becomes a humidity pump. It's why our hottest temperatures come from the west.

It looks like isolated storms tomorrow afternoon. I would think that SPC should upgrade us to a marginal risk for tomorrow.

agreed - I also think SPC issued that Severe Watch Monday into NJ just to be safe rather than sorry . Looking further down the road if that Bermuda HP sticks around and gets into a favorable position for east coast tropical trouble - the ingredients are showing up in the Atlantic

I think some or many of these WU stations are not installed in favorable areas of a property to get accurate readings for some attached individual instruments . I would not buy one because the only favorable area on my property is on top of my roof - and my roof climbing days ended years ago. Used to have a station there for 20 plus years until Labor Day 1998 - the day the Tornado ripped it off my roof along with my Chimney.

That’s  actually a NWS COOP station out in Baiting Hollow which gets included in the weather roundups across the area. It could be the warmest temperature ever recorded on Eastern Long Island. 

The big story this summer is how much warmer it is than past developing super El Niño summers. Some stations approached all-time highs back in early July. But the smoke prevented more 100° readings back in mid-July.

Poor installation locations and who knows what the accuracy/quality of the station Is to begin with. Add to that the lack of maintenance on the stations and you get many questionable readings.

1928: At 24th & M DC - Washington set a record of 7.31 inches of rain in 24 hours. East Coast Storms (Ref. AccWeather Weather History)

1933: The shade temperature reached 136.4° at San Luis, Mexico, to unofficially share the world record with Aziziyah, Lybia. (Ref. Wilson Wx. History)

1936: The warmest August temperature ever recorded in both Oklahoma City and Wichita Falls occurred on this date. The morning low in Oklahoma City was a warm 82°, before both cities warmed up to a very hot 113°. The old August record in Oklahoma City was 112, which was set the day before. In Wichita Falls, this record was tied on 8/6/1964. (Ref. Wilson Wx. History)
 

1940 - A Category 2 hurricane struck the Georgia and South Carolina coast. A 13-foot storm tide was measured along the South Carolina coast, while over 15 inches of rain fell across northern North Carolina. Significant flooding, the worst since 1607, and landslides struck Georgia, North Carolina, Tennessee, and Virginia during the system's slow trek as a weakening tropical storm, and then as an extratropical cyclone, through the Southeast. The landslides which struck North Carolina were considered a once in a century event. Damages relating to the storm totaled $13 million (1940 USD), and 50 people perished.

1944 - The temperature at Burlington, VT, soared to an all-time record high of 101 degrees. (The Weather Channel) The Dog Days officially come to an end on this date, having begun the third day in July. Superstition has it that dogs tend to become mad during that time of the year. (The Weather Channel)

 

1968: A young girl in a lake was injured when a dust devil near Bristol, CT carried a 150 pound roof covering a picnic area into a lake.  (Ref. AccWeather Weather History)

1974: Illinois--Lightning struck and killed a boy who was hunting in Jersey County. (Ref. Lightning-The Underrated Killer.pdf)

1975: A line of heavy thunderstorms moved rapidly across portions of eastern South Dakota and into Iowa. In Canton, winds were estimated at 70 mph while the National Weather Service in Sioux Falls was belted with a 69 mph gust. The high winds leveled many trees and also destroyed some older buildings in Miner County while the Sioux Falls area had only tree damage and minor building damage. The storms maintained their strength as they moved into northwest Iowa. An uncompleted trucking terminal and several trucks received around $10,000 dollars in damage in Sac County while a grain storage bin was flattened and boat house destroyed near Storm Lake. (Ref. Wilson Wx. History)

1979: The mercury was plummeting over portions of the Arrowhead of Minnesota. The temperature at Embarrass, MN fell to 28°, accompanied by a hard freeze. (Ref. AccWeather Weather History)

 

1980 - Clouds and moisture from Hurricane Allen provided a brief break from the torrid Texas heatwave, with daily highs mostly in the 70s to lower 90s. (The Weather Channel)

1984: Dulles Airport records 11 inches of rain in 24 hrs. (Ref. Dulles Weather Records) (Ref. AccWeather Weather History) Miami, FL set a record high for the date with 96°. Then a thunderstorm cools things off to 70°, which set a record low for the date. (Ref. Wilson Wx. History)

1986: Atlanta, GA saw its streak of 38 consecutive days with 90 degrees or hotter finally come to an end with a reading of 89 °F. (Ref. AccWeather Weather History)

1987 - An early evening thunderstorm in Wyoming produced hail up to two inches in diameter from Alva to Hulett. Snow plows had to be used to clear Highway 24 south of Hulett, where hail formed drifts two feet deep. (The National Weather Summary)

1988 - Moisture from what remained of Tropical Storm Beryl resulted in torrential rains across eastern Texas. Twelve and a half inches of rain deluged Enterprise TX, which was more than the amount received there during the previous eight months. Philadelphia PA reported a record forty-four days of 90 degree weather for the year. Baltimore MD and Newark NJ reported a record fourteen straight days of 90 degree heat. (The National Weather Summary)

1989 - One of the most severe convective outbreaks of record came to a climax in southern California after four days. Thunderstorms deluged Benton CA with six inches of rain two days in a row, and the flooding which resulted caused more than a million dollars damage to homes and highways. Thunderstorms around Yellowstone Park WY produced four inches of rain in twenty minutes resulting in fifteen mudslides. Thunderstorms over Long Island NY drenched Suffolk County with 8 to 10 inches of rain. Twenty-three cities in the southeastern U.S. reported record low temperatures for the date. It was, for some cities, the fourth straight morning of record cold temperatures. (The National Weather Summary) (Storm Data)

1993: Ashley National Forest, Utah: A tornado strikes in the Uinta Mountains, 20 miles northeast of Roosevelt, Utah. It demolishes 1,000 acres of trees in the Ashley National Forest at 10,800 feet above sea level. (Ref. WxDoctor)

 

1999 - An F2 tornado touched down in the metropolitan area of Salt Lake City. The tornado lasted ten minutes and killed one person, injured more than 80 people, and caused more than $170 million in damages. It was the most destructive tornado in Utah's history and awakened the entire state's population to the fact that the Beehive State does experience tornadoes.

2001: A woman was struck and killed by lightning while on a boat in the Chesapeake Bay near the Oceanview section of Norfolk, VA. An Amherst, VA woman was struck by lightning and received minor injuries. (Ref. Lightning - Virginia Weather History)

2002: The National Weather Service at North Platte, NE reported huge 7 inch hail three miles east of Halsey, NE. (Ref. Wilson Wx. History)

2004: Wisconsin: A cold air mass descends over Wisconsin. Ten cities report maximum temperatures that are among the coldest ever for the month. Three break old records, two tie records and five record second lowest maximum temperature. High temperatures range from 52°F in the north to 59°F in southern part of the state. (Ref. WxDoctor)


2007: Dutch Harbor, AK set their all-time high temperature with a reading of 81°. (Ref. Wilson Wx. History)

 

2016: August 9-16. Weak low pressure combined with abundant Gulf moisture produced phenomenal rainfall and flooding across central Louisiana, inundating entire neighborhoods and towns, especially around Lafayette and Baton Rouge. Rainfall totals exceeded 20 inches in as little as two days. Thirteen people died and economic costs ranged from $10 to $15 billion.

Maybe it could reduce the highs on the days with more smoke by 1-2° from the model forecasts. Just glad that it’s significantly further away from our area than the record wildfires in Ontario back in mid-July. The smoke was so thick during that period that it resulted in 5-6° cooler high temperatures than model forecasts.

I wonder if August is going to complete the trifecta of positive temperature departures during the first half of the month and negative temperature departures during the second half of the month for this summer, or if August will end up being the most consistently warm month.
