Historical:

 

1928: A violent, estimated F4 tornado, with winds of 200 mph, tore across Rockford, Illinois. The tornado first touched down 8 miles south-southwest of Rockford and moved across the southeast part of the city. The tornado was on the ground for 25 miles with a width varying from 200 to 500 feet. A total of 14 people were killed, with around 100 injuries reported in Rockford alone. Two hundred buildings were damaged or destroyed. 

1937 - The mercury soared to 92 degrees at Seattle, WA, a record for September. (The Weather Channel)

1944 - A very destructive hurricane swept across Cape Hatteras and Chesapeake Bay, side swiped New Jersey and Long Island, and crossed southeastern Massachusetts. The hurricane killed more than four hundred persons, mainly at sea. The hurricane destroyed the Atlantic City NJ boardwalk. (David Ludlum) (The Weather Channel)

1970 - The temperature at Fremont, OR, dipped to 2 above zero to equal the state record for September set on the 24th in 1926. (The Weather Channel)

 

1977: Severe thunderstorms produced several tornadoes in eastern Arkansas, killing one.

1987 - Barrow, AK, received 5.1 inches of snow, a record for September. (Sandra and TI Richard Sanders - 1987)

1987 - Thunderstorms developing along a cold front produced severe weather from Minnesota to Texas. Thunderstorms in Iowa produced baseball size hail at Laporte City, and 80 mph winds at Laurens. Hail caused more than ten million dollars damage to crops in Iowa. Thunderstorms in Missouri produced wind gusts to 75 mph at Missouri City and Kansas City. A thunderstorm in Texas deluged the town of Fairlie with two inches of rain in just two hours. (Storm Data) (The National Weather Summary)

1988 - Hurricane Gilbert made the first of its two landfalls on Mexico, producing 170 mph winds at Cozumel. (The Weather Channel)

1988 - Thunderstorms produced severe weather over the Texas panhandle during the evening hours. One thunderstorm spawned a strong (F-2) tornado in the southwest part of Amarillo, and deluged the area with five inches of rain. The heavy rain left roads under as much as five feet of water, and left Lawrence Lake a mile out of its banks. Hurricane Gilbert lost some of its punch crossing the Yucatan Peninsula of Mexico. Its maximum winds diminished to 120 mph. (The National Weather Summary) (Storm Data)

1989 - Unseasonably cool weather prevailed across the south central U.S. Eight cities reported record low temperatures for the date, including Raton NM with a reading of 30 degrees. The afternoon high of 59 degrees at Topeka KS marked their third straight record cool maximum temperature. Unseasonably warm weather continued in the Pacific Northwest. Seattle WA reported a record eight days in a row of 80 degree weather in September. (Storm Data) (The National Weather Summary)

 

2005: Hurricane Ophelia caused some damage and beach erosion along the United States coastline from Florida to North Carolina. The closest approach occurred on September 14 and 15 with its western eyewall crossing land and the eye remaining just offshore in the Carolinas.

 

2008: Hurricane Ike became extratropical on this day. The St. Louis Metropolitan Area experienced hurricane conditions, with Ike's remnants inflicting severe damage to homes. Several areas in Illinois and Indiana, already flooded by the frontal boundary to the north, saw significant additional rainfall. Due to flooding in Chicago, a state of emergency was declared for Cook County due to flooding of the Des Plaines River. Hurricane-force wind gusts were reported to the east of the center across parts of Kentucky, Indiana, Ohio, and Pennsylvania with significant wind damage including structural damage to buildings and trees.

High of 75F here this afternoon, great day to be outdoors. Headed north to the Berkshires this afternoon for a long weekend.

Tonight could be the coolest night so far in many areas in the northern Mid-Atlantic area. Readings in New York City could dip below 60° for the first time this fall. Temperatures in the suburbs will fall into the lower and middle 50s. Some of the more distant or colder suburbs could see temperatures drop into the 40s.

Tomorrow will then be fair but unseasonably cool. Much of the region will likely see temperatures top out in the upper 60s and lower 70s.

Hurricane Lee will streadily move toward North American landfall. The guidance favors landfall in New Brunswick, but landfall along the Maine or Nova Scotia coast cannot be ruled out. Eastern Long Island and eastern New England could some periods of heavy rain and gusty winds as Lee passes offshore.

The ENSO Region 1+2 anomaly was +2.9°C and the Region 3.4 anomaly was +1.6°C for the week centered around September 6. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +3.20°C and the ENSO Region 3.4 anomaly has averaged +1.38°C. El Niño conditions will likely continue to strengthen into the fall with the current East-based event transitioning to a basinwide El Niño for the upcoming winter.

The SOI was -13.37 today.

The preliminary Arctic Oscillation (AO) was +0.113 today.

On September 12 the MJO was not available. The September 11-adjusted amplitude was 2.188 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 81% probability that New York City will have a warmer than normal September (1991-2020 normal). September will likely finish with a mean temperature near 71.6° (2.4° above normal).

Beautiful outside with dewpoints down to the low 50s, and heading down into the high 40s this afternoon. They'll stay in the 40s the next 2 days. Just a brief minor humidity spike sunday night into monday (dewpoints near 60) with a couple showers possible, and then back to spectacular weather tuesday and wednesday with dewpoints falling back down to the low 50s. So overall a nice low humidity stretch over the next week, as you would hope for in mid September. 

Long range looks warm as bluewave talked about, but in late September that type of pattern would result in some days with high temps in the low 80s and dewpoints around 60. Nice extended summer weather. 

Yeah, looks like 80s will return on the warmer days but the higher minimums may drive the departures with high pressure shifting east of New England and onshore flow.

Outer cloud shield from Lee over Long Island this morning.

Most of the bronx down into the middle and upper 50s.

[ForestHillWx]

52 now. Slight beeze out of the NW.

I’ve seen people wearing parkas this morning; I’m sticking with shorts/t-shirt until October. 

[Rjay]

Low of 50

[Snowlover11]

got down to 53

Quick review on Sept 7-14 rainfall:  Was 1-2" lower than long range guidance anticipated with max amounts in our NYC subforum 6-7.5" (not all data probably in CoCoRaHs but enough to demo the FF near AVP, PHL, Ocean County, CT/MA).  Were there any 10's in our subforum..probably NOT.  Our home here in Wantage NJ was a paltry 1.41. 

Here's the always subdued multisensor smoothed data from the NWS, and CoCoRaHs. Click for clarity.

Lee and its scraper impacts coming to coastal New England as well modeled - well in advance. 

Nothing else excites me about extremes the rest of September around our NYC subforum. 

 

[steve392]

Some impressive rainfall numbers!

[WestBabylonWeather]

Funny. This same day a few years ago is when we first hit the 50s

Fall is in the air now

Come to where I am on the northern edge of the pine barrens and get your fill of wasps and European Hornets. They’re all over my property, was stung by a Paper wasp last week.
