Sydney Sweeney says hold my beer

Pleasantly surprised this evening with 0.30" after a brief deluge followed by some steadier rain.
Several good flashes of lightening and some thunder, enough to send the dog scurrying into one of her hiding spots.

[steve392]

Getting lightning detections in my area. Maybe we'll actually get something. 

[anthonymm]

Extraordinarily warm overnight lows next few days. 70 overnight low in central park tonight? Gotta be one of the latest lows above 70 F in history right?

No. The record is October 10, 2018.

Fujiwhara type reaction. Very unique. Not sure what sort of impacts, if any, there would be. 

[donsutherland1]

The early guidance on Invest 94 now shows a cluster of solutions indicating that the system could be approaching North Carolina in five days. Much can still change, as five day forecasts are subject to large errors. A near miss or out-to-sea solution remains viable.

[bluewave]

This looks like our best rainfall potential in a while. Good signal from the CAMs for a widespread 1.5”+ with pockets of 3”+ possible. Just had brief heavy downpour here.

Some rumbles here as well with a paltry .08".

[lee59]

.23 inch of rain here over night.

[SACRUS]

70 / 69 cloudy.   Cloudy / warm - humid - Storms / shower , rain later into Thu late AM with 1 - 3 inches locally.   Clearing out later Thu and a warm Friday - back into the 80s for most.   The weekend looks dry Sat and most of Sunday but clouds could be sticking around both days.  Watch the tropics 9/30 - 10/2.  Overall warm with ridge 10/2 and beyond.

Historical:

 

 

1869: Heavy rain dumps nearly 10 inches on the White Earth Reservation, MN. (Ref. AccWeather Weather History)

1888: The earliest frost of record hit the southern states, covering South Carolina, Georgia and, northern Florida. (Ref. AccWeather Weather History)

1926 - The temperature at Yellowstone Park dipped to nine degrees below zero. It was the coldest reading of record in the U.S. during September. Severe freezes were widespread over the northwestern U.S. causing great crop destruction. In Washington State, Spokane County experienced their earliest snow of record. Harney Branch Experiment Station in Oregon reported a temperature of 2 degrees above zero to establish a state record for the month of September. (David Ludlum) (The Weather Channel)
 

1926: The temperature at Yellowstone Park drops to 9 degrees below zero, making it the coldest September reading ever recorded in the US.

1939: A thunderstorm on this day dropped 6.45 inches in six hours at Indio, CA. This rainfall preceded “El Cordonazo” or “The Lash of St. Francis”, an actual tropical storm. For the entire storm, which started on this day and ended on the 26th, four inches of rain fell across the deserts and mountains as a dying tropical cyclone moved across Baja California into southwestern Arizona. This storm was the second tropical cyclone to impact California during this month. A strong El Niño may have contributed to the activity. The tropical storm produced 50 mph winds over the ocean and estimated seas of 40 feet. September rain records were set in Los Angeles with 5.66 inches and 11.6 inches at Mt. Wilson. 45 people died from sinking boats, and harbors were damaged. Total damage was estimated at $2 million. Californians were unprepared and were alerted to their vulnerability to tropical storms. In response, the weather bureau established a forecast office for Southern California, which began operations in February of 1940.

1950 - A smoke pall from western Canada forest fires covered much of the eastern U.S. Daylight was reduced to nighttime darkness in parts of the Northeast. The color of the sun varied from pink to purple, blue, or lavendar. Yellow to grey-tan was common. (24th-30th) (The Weather Channel)

1956: Hurricane Flossy made landfall near Destin, Florida as a Category 1 storm. 

1972 - Lightning struck a man near Waldport, OR, a young man who it so happens was carrying thirty-five pieces of dynamite. (The Weather Channel)

1975: Remnants of Hurricane Eloise merge with a frontal system over Northeast, resulting in tremendous flooding. (Ref. AccWeather Weather History)

1984: Behind a strong cold front, Bismarck, ND had a record early season snowfall of 5 inches, their heaviest September snowfall. Along with the snow came record cold temperatures across parts of the northern Rockies. Billings, MT recorded their coldest September temperature of 22° followed by an afternoon high of just 31°. Other daily record lows included: Sheridan, WY: 13° and Casper, WY: 22°. Ahead of the front, along with dramatically warmer temperatures, by as much as 40 degrees plus, upper level dynamics were in place for severe weather. Crawford and Vernon Counties in Wisconsin reported baseball sized hail and 3 inch diameter hail was reported in La Crosse County, Wisconsin with this same cluster of storms. (Ref. Wilson Wx. History)

1986: An F2 tornado, unusually strong for one in California, touched down just southeast of Vina on this day and traveled two miles through an agricultural area. A mobile home was destroyed, injuring a 22-year-old occupant. Eleven other buildings were damaged or demolished, and 50 acres of walnut orchards were flattened.

1987 - The first full day of autumn proved to be a pleasant one for much of the nation, with sunny skies and mild temperatures. Thunderstorms again formed over Florida and the southwestern deserts, and also formed along a cold front in the northeastern U.S. A storm spotter at Earp CA sighted a couple of funnel clouds, one on the California side of the state line, and the other on the Arizona side. (The National Weather Summary) (Storm Data)

1988 - Thunderstorms developing along a stationary front produced large hail and damaging winds in the southeastern U.S., with reports of severe weather most numerous in North Carolina. Golf ball size hail was reported at Tick Creek and a number of other locations in North Carolina. (National Weather Summary) (Storm Data)

1989 - Forty-seven cities between the Rockies and the Appalachians reported record low temperatures for the date. Lows of 38 degrees at Abilene TX, 34 degrees at Jackson KY, and 36 degrees at Midland TX established records for the month of September. The low of 36 degrees at Midland smashed their previous record for the date by thirteen degrees. Fayetteville AR and Springfield MO reported their earliest freeze of record. Thunderstorms produced torrential rains in northeastern Florida. Jacksonville was deluged with 11.40 inches of rain, and flash flooding resulted in two deaths. (The National Weather Summary) (Storm Data)

2001: A weak, F0 tornado passed in the sight of the Washington Monument. Soon after, an F3 tornado struck College Park, Maryland.

 

2001: It was just 13 days after the 9/11 terrorist attack when the Emergency Action Notification System sounded in Washington, DC. Many people immediately thought the alert was for another attack, but it was actually for a tornado warning. The dramatic severe weather statement from the National Weather Service at Sterling, VA was that a tornado had been sighted near the Pentagon. (Ref. Wilson Wx. History)

2005 - Early in the morning, major Hurricane Rita came ashore near the Texas/Louisiana border

 

2005: Early on the morning of September 24, 2005, Major Hurricane Rita came ashore near the Texas/Louisiana border.

Continuing review for a possible thread 6PM today for 22z/24-12z/26.Pprior posts by Bluewave have it right. 1-3 iso 5 possible. 

Getting complex.

The closed low OH Valley will happen and looking like we get something addition from it 18z Sat-18z Sun.  

Thereafter, uncertainty greater but as noted previously, tropics get involved with the east coast trough-W Atcl ridge.  At a minimum, I would not be fishing in the coastal waters next Tue-Wed. Even if the tropics peel east-shunted s, the large cool high settling into New England sets up the potential for an early season modest gale on the CW s of LI and e of NJ, assisted by the larger BL temp lapse rate. 

Offline most of the day. 0.24 here in this part of nw NJ last evening.

I can't find prior storm events before 2010 on Upton's site. Apparently text takes up a huge amount of storage space and so they can't spare it. It's been this way for years.

 

 

I don't get it, lol.  I save so much text on my hard drives, they should easily be able to store everything going all the way back to 1869 when records began.

It's like that silly video limit on here.

I always wondered what caused 1989-1990 to be as extreme as it was, from extreme cold and widespread severe weather and Thanksgiving snow and December arctic cold to record warmth January thru March.

What I remember the most though is how early all the fall foliage dropped from the trees thanks to the early extreme cold and very windy weather.  ALL the leaves were off the trees here before Halloween!  That has not happened before nor since.

Clean sweep for 2017 and everyone was within one degree of each other, that must be VERY rare (I wonder if there's ever been an instance of the same record high temperature at all 4 locations at the same time?)
