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.

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.

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.

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)

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.

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.

I recall that the Dog Days of Summer were referred to as such from ancient astronomers because the appearance of the Dog star Sirius during Summer was erroneously thought to have added heat to the Earth. Never heard the mad dog claims though.

I really damn hope the dew points start crashing once we flip the calendar.

Parts of the region could see a shower or thundershower this evening and tonight. Above normal temperatures will persist through tomorrow or Thursday. Highs will generally top out in the middle and upper 80s. 

Cooler air will move into the region to close of the week. As a result, Friday through Sunday could see highs mainly in the upper lower 80s.

The ENSO Region 1+2 anomaly was +4.1°C and the Region 3.4 anomaly was +2.6°C for the week centered around August 6. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +3.72°C and the ENSO Region 3.4 anomaly has averaged +2.15°C. The ongoing strong El Niño, which has reached super El Niño threshold, will continue to strengthen through the summer.

The SOI was +6.86 today. 

The preliminary Arctic Oscillation (AO) was -0.346 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 53% probability that New York City will have a warmer than normal August (1991-2020 normal). August will likely finish with a mean temperature near 76.3° (0.2° above normal). 

Supplemental Information: The projected mean would be 1.0° above the 1981-2010 normal monthly value.
