Historical:


 

1787 - Tornadoes were reported in Connecticut, Rhode Island, Massachusetts, and New Hampshire. Wethersfield CT was hard hit by the tornado outbreak. (David Ludlum)

1886: This tornado was estimated to be an F3 and moved northeast from 5 miles southwest of Newark, SD through town and into North Dakota. Only three buildings were reportedly undamaged at Newark, and a bartender at a saloon was killed. Three people died in two homes on adjoining farms two miles southwest of town. A saddle from a Newark stable was carried for a half mile. In North Dakota, homes and barns was damaged along the Wild River. (Ref. Wilson Wx. History)

1946 - Saint Louis, MO, was deluged with a record 8.78 inches of rain in 24 hours. (The Weather Channel)

1950: In 45 years of Hawaiian meteorological records, a hurricane had never affected the islands. On this date, Hurricane Hiki was moving north of the islands. Residents held their breath when the storm turned southwestward. Fortunately, the storm resumed its westward course and missed the islands. The highest wind speed recorded was at Kilauea Lighthouse, Kauai at 68 mph. (Ref. Wilson Wx. History)

1967 - The sundance fire in northern Idaho was started by lightning. Winds of 50 mph carried firebrands as much as ten miles in advance to ignite new fires, and as a result, the forest fire spread twenty miles across the Selkirk Mountains in just twelve hours, burning 56,000 acres. The heat of the fire produced whirlwinds of flame with winds up to 300 mph which flung giant trees about like matchsticks. (David Ludlum)

1969: Camille became a hurricane south of Cuba and entered the Gulf of Mexico as a major hurricane with winds of 115 mph. (Ref. AccWeather Weather History)

1971: Some of the worst flooding that ever occurred in western north Texas happened on this date. Heavy rain began on the 14th, but the worst of the rain and most of the flooding was on this date. On that day, rainfall amounted 4 to 11 inches. The Wichita River, on the northwest side of Wichita Falls, TX crested at its highest level in 30 years. At least 10 families were forced to evacuate their homes along the river as the waters rapidly rose. The river also rose so high that its swift-flowing waters undercut several streets, causing them to collapse. The official rainfall at the National Weather Service Office in Wichita Falls was 4.52 inches, making this the wettest August day ever observed in the city. (Ref. Wilson Wx. History)

1977: Lightning struck a cement well covering near Mankato, MN, causing shattered pieces of concrete to be blown over 30 feet, damaging cars.
(Ref. AccWeather Weather History)  Hurricane Doreen tracked north-northwest along the west coast of Baja California, dissipating over the coastal waters. Areas of southern California received at least two inches of rain with up to 8 inches in the mountains on this date through the 17th. Debris flows and flooding from Henderson Canyon into the Borrego Springs De Anza area damaged 100 homes. Mud flows grew to five feet deep. Flooded roads resulted in desert areas. Four people died and damage was set at $25 million dollars. (Ref. Wilson Wx. History)

1979: Early season chill across the Midwest and East produced record low temperatures for the date including: International Falls, MN: 33°, Grand Forks, ND: 36°, Madison, WI: 37°, St. Cloud, MN: 39°, Fargo, ND: 43°, La Crosse, WI: 43°, Dubuque, IA: 45°, Peoria, IL: 45°, Indianapolis, IN: 45°, Mansfield, OH: 46°-Tied, Moline, IL: 47°-Tied, Akron, OH: 47°- Tied, Youngstown, OH: 47°-Tied and Cincinnati, OH: 49°. (Ref. Wilson Wx. History)

1983 - Hurricane Alicia formed on this day and was the costliest tropical cyclone in the Atlantic since Hurricane Agnes in 1972. It struck Galveston and Houston, Texas directly, causing $2.6 billion (1983 USD) in damage and killing 21 people. This storm was the worst Texas hurricane since Hurricane Carla in 1961. Also, Alicia was the first billion-dollar tropical cyclone in Texas history.

1987 - Thunderstorms developing ahead of a sharp cold front produced severe weather in the Upper Midwest during the afternoon and evening hours, with Minnesota and eastern South Dakota hardest hit. A thunderstorm in west central Minnesota spawned a tornado at Eagle Lake which killed one person and injured eight others. A thunder- storm in eastern South Dakota produced softball size hail at Warner. (The National Weather Summary) (Storm Data)

1988 - Thirty five cities in twenty states in the north central and northeastern U.S. reported record high temperatures for the date, including Lamoni IA and Baltimore MD, where the mercury hit 105 degrees. Temperatures 100 degrees or above were reported in twenty-two states. Pierre SD was the hot spot in the nation with a high of 114 degrees. Bluefield WV reported eight straight days of record heat. (The National Weather Summary)

1989 - Evening thunderstorms in eastern New Mexico produced wind gusts to 66 mph at Clovis. Evening thunderstorms in West Texas produced baseball size hail around Hereford, Dimmitt, Ware and Dalhart. (The National Weather Summary) (Storm Data)

1993: Slow moving thunderstorms produced torrential rain across Mower County, MN. Rainfall exceeded 4.00" over most of the county with the highest total of 10.25" at Adams, MN. Significant flooding occurred within the city of Austin, MN, where 1,000 homes suffered water damage. The Cedar River in Austin rose rapidly out of its banks through the day. It crested at 21.3 feet, 6.3 feet above flood stage. (Ref. Wilson Wx. History)

1994: Tropical Storm Beryl formed in the northeast Gulf of Mexico and moved slowly east northeast, crossing the Florida panhandle coastline near Panama City. Beryl greatly added to the woes of people who were still recovering from Tropical Storm Alberto in July. At landfall the maximum sustained wind was estimated at 60 mph. The greatest rainfall total of 10.69 inches were observed at Apalachicola, but higher values likely occurred to the east of this location. Beryl weakened to a tropical depression as it moved northeast into extreme southwest Georgia at early on the 16th. There were no deaths and only 1 injury directly attributable to Beryl and damage was estimated at $5.9 million dollars. (Ref. Wilson Wx. History)

2004: Severe flooding in Death Valley National Park in California caused extensive flooding. The flooding completely washed away several miles of roadway and caused damage to several rest areas. Two people traveling along Highway 190 were caught in the flooding and killed. Damage was estimated at $20 million dollars and took 3 months to completely repair the damage. (Ref. Wilson Wx.

Temperatures will top out in the lower to perhaps middle 80s in a few warm spots to start the weekend. Clouds will increase on Sunday holding the temperature to the upper 70s or lower 80s.

Showers and thundershowers are likely Sunday night into Monday. A few locations could see heavy downpours.

Following the frontal passage, Monday through Wednesday should feature temperatures in the lower 80s, along wth partly to mostly sunny skies. 

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 -22.03 today. 

The preliminary Arctic Oscillation (AO) was -0.810 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 56% probability that New York City will have a warmer than normal August (1991-2020 normal). August will likely finish with a mean temperature near 76.5° (0.4° above normal). 

Supplemental Information: The projected mean would be 1.3° above the 1981-2010 normal monthly value. 

 

Thoughts on late august and sept? Do you think summer sticks around till October or do we get an early start to fall?

Late August/early September: Probably near normal with perhaps a cool period. Remainder of September: generally above normal. October: I am really uncertain.
