Historical:

1775: The Independence Hurricane This savage hurricane raged from North Carolina to Newfoundland. Heavy rains began to fall across the colony on the 29th of August and slowly increased with time. The coast was ravaged from Currituck to Chincoteague. Wharves and storehouses on the waterfront of Norfolk were devastated. Bridges were carried away by the raging waters. At Williamsburg, mill dams broke and corn stalks were blown flat. Winds blew furiously until 10:00 p.m. Many ships were damaged as they were thrown ashore at Norfolk, Hampton, and York. Around twenty-five vessels were run ashore, or "irrecoverable gone." The gun ship H.M.S. Mercury was driven hard aground on Portsmouth Point at 5:00 p.m. on the 2nd. It was stranded in two feet of water for eight days (Shomette). The Liberty became "hopelessly stranded" in Back River, near Hampton. A number of locals boarded her, captured the crew, secured her goods, and set the ship afire in the first outright act of war. A full blockade of Hampton Roads thereafter brought shipping to a halt for three months. At least twenty-five died due to shipwreck.(Ref. The Independence Hurricane)

1882: Possibly the first photograph of a lightning strike was taken on this day by William Jennings in Philadelphia, Pennsylvania. 

1887: The U.S. Army Signal Service station in Greenville, SC reported a minimum temperature of 50°F. This observation at Greenville still stands as the record low for the day. Additional stations across the state recorded low temps in the low 50's.

1935 - Perhaps the most intense hurricane ever to hit the U.S. struck the Florida Keys with 200 mph winds. The hurricane produced a fifteen foot tide and waves thirty feet high. 400 persons perished in the storm on that Labor Day. The barometric pressure at Matecumbe Bay FL hits a record low for the U.S. of 26.35 inches. (David Ludlum)

1950 - The temperature at Mecca, CA, soared to 126 degrees to establish a U.S. record for the month of September. The low that morning was 89 degrees. (The Weather Channel)

1950: The temperature at Mecca, CA soared to 126 degrees to establish a U.S. record for the month of September. The low that morning was 89 degrees. (The Weather Channel) (Ref. WxDoctor) (Ref. AccWeather Weather History)

1953: Boston, Massachusetts had 100 °F for the second time ever in September. Chicago, IL hit 101° for the second day in a row and the tenth of 11 consecutive days with a high temperature at 90° or higher. (Ref. NOAA Boston Weather Events)

1961: Denver, CO picked up 4.2 inches of snow, the earliest measurable snow for the Mile High City. (Ref. AccWeather Weather History)

1982: A wind gust of 121 mph was reported at the Chautauqua County Airport near Jamestown, NY causing an estimated half million dollars in damages to the terminal building, planes, cars and landing instruments. Rainfall totals exceeded two inches in places. (Ref. Wilson Wx. History)

1985

1985 - After teasing residents along the Gulf of Mexico for two days, Hurricane Elena finally came ashore at Biloxi MS. The hurricane, packing winds of 127 mph, caused more than a billion dollars damage. (The Weather Channel)

1987 - Late evening thunderstorms in the Northern Plains Region produced wind gusts to 75 mph at Jordan MT, and a ""hot flash"" at Redig SD. The temperature at Redig rose from 66 degrees at 10 PM to 86 degrees at 11 PM as thunderstorm winds gusted to 36 mph. Nine cities in the Upper Ohio Valley, the Tennessee Valley and the Central Gulf Coast States reported record low temperatures for the date, including Elkins WV with a reading of 38 degrees. (The National Weather Summary) (Storm Data)

1988 - Unseasonably hot weather prevailed in the northwestern U.S. Afternoon highs of 98 degrees at Olympia WA, 98 degrees at Seattle WA, 105 degrees at Portland OR, and 110 degrees at Medford OR, established records for the month of September. Quillayute WA equalled their September record with an afternoon high of 97 degrees. (The National Weather Summary)

1989 - Eight cities in the Gulf Coast Region reported record high temperatures for the date as readings soared into the upper 90s. Houston TX and Port Arthur TX hit 99 degrees. Late evening thunderstorms, developing ahead of a cold front, produced wind gusts to 63 mph at Dickinson ND, and golf ball size hail in North Dakota and Nebraska. Winds along the cold front itself gusted to 62 mph at Buffalo SD. (The National Weather Summary) (Storm Data)


1996: After teasing the entire Atlantic coast with winds as high as 140 mph, Hurricane Edouard skirted New England without making landfall. Hurricane force winds were recorded on Nantucket and Cape Cod, but wind damage was relatively minor.   

 

1996: Large swells from Hurricane Fran knocked five people out of an 18-foot fishing boat in Jupiter Inlet, FL. The Coast Guard rescued all five people. (Ref. Wilson Wx. History)

2002: An F3 tornado roared into downtown Ladysmith, WI at mid-afternoon, heavily damaging 64 blocks of the business district. Fortunately, it was Labor Day, and most of the stores were closed for the holiday or the toll would have been much worse. The National Weather Service came under fire for not issuing a tornado warning before the storm struck.
(Ref. Wilson Wx. History)

2003: Indianapolis, IN was drenched with 7.20 inches of rain on this date for its greatest single day rainfall on record. (Ref. WxDoctor)

2006: Tropical Storm Ernesto dumped 8.93 inches of rain on Norfolk, VA for the city's greatest single day rainfall on record. (Ref. Wilson Wx. History) (Sep. 1st-2nd) Heavy rains from the remnants of Tropical Storm Ernesto fell on SE PA. In Schwenksville, a man jumped into an overflowing retention basin to try to rescue his dog. The dog was sucked into and through the outflow pipe and survived; his master drowned.
(Ref. Weather Guide Calendar with Phenomenal Weather Events 2011 Accord Pub. 2010, USA)

2008: Northeastern Illinois: In Chicago the thermometer at O'Hare IAP hits 94°F (34.4°C), and Midway tops out at 95°F (35°C), the first such high there in 761 days, and the warmest day of the year Kankakee, New Lennox, Plainfield and Palatine (my home town hit 97°F. (Ref. WxDoctor)

2002: An F3 tornado destroyed much of the downtown area of Ladysmith, Wisconsin. Overall damage was estimated at $20 million, but there were no fatalities.

I have no confidence in any met forecast anymore..seems to change every 12 hours and now seeing showers for Friday

[winterwarlock]

Are these long range forecasts of long stretch of dry sunny weather after Friday believable?

[Cfa]

Sun poking out near ISP.

I’m not expecting anything to happen out here, although more often than not, the best storms I’ve seen out here have come by “surprise”.

What a historic week and day in 1953 we had! Much better than the crop soggy weather we have now. I dont like either my weather or my food to be soggy.

Rather no rain and no clouds and no fog and pump all this moisture to Mars where they really need it. Hot sunny and clean blue skies and dry weather are the best.

This is exactly why we will never break the records from years like 1936, 1953 and 1966. Mark my words Chris it will NEVER happen. We will have plenty of very hot summers, I fully expect next summer to be like 1983 and 2010, and get to the 100-102 range maybe three or more times, but the high end heat of 1936 (106 at Central Park) 1953 (102 in September, a mega heat wave of 2 weeks length), 1966 (107 at LGA, 104 at JFK) that will never happen again, at least not in our lifetimes. Obviously other regions will break their all time records because climate change means different things to different parts of the world and in different times of the year. Our springs haven't become hotter either. 1991 a pre el nino year had a spring much hotter than this year and the summer was hotter too.

We are locked in with fog here and have been for hours in the Poconos. Edit- we just had a brief shower, no thunder thank goodness.

 

I still haven't been able to figure out my exact elevation Google Gemini gave me some ridiculous numbers, 1666 feet at the front of my property (facing the lake) and 1692 feet at the back of my property (facing an open field). And something about that open field behind my property rising to 1740 feet haha. I think I will stick with the average of my apps and the barometer altimeter conversion process that says it's between 1530 and 1580 feet.

 

Those numbers from Gemini might not be any more accurate than those inflated temperatures on weather underground we talked about before. I dont think anyone does it intentionally, I just think the properties there are too close to each other for proper siting and like you said no one wants to climb a roof to plant an Anemometer lol. And many of these weather units are all in one which makes it even more difficult.  A wind instrument needs to be at 33 feet while the thermo hydro sensor belongs at 6 feet while the rain gage needs to be on a flat surface twice the distance away from the height of any near by trees, roofs, etc. I think I finally got the thermo hydro part right as my temperature measurements are within 1 to 2 degrees of MPO on all my sensors placing them on the North side of my house under the eave of a deck. The rainfall and wind measurements are off though. I would need to put the Anemometer on my balcony but I can't because the entire unit would have to go there and that area is very sun exposed so the temperature would be inflated. I see these modern units have offsets you can input to account for that but I don't find that to be scientific (the offset would need to be different for different times of the year as the sun angle and sun path in the sky changes) and I'd worry about intense heat damaging the equipment anyway, I remember in May there was one day it hit 118 degrees on my balcony when the actual outside temperature was more like 91 lol.
