I’ll give this a try. would love to track storms tracking near cape cod. Would screw the interior but be great for the coast. Ala Juno
 

 

 

It all depends on where one is. And those who live in Ohio would love to see storms tracking to over interior NY State. I suspect the season is going to be hyperactive and storms are going to track all over the place. Very few people likely to be disappointed. I just hope we we some cold air to work with.

A storm brought a soaking rain to the region late yesterday and today. Rainfall totals included:

Bridgeport: 1.19"
Islip: 1.32"
New Haven: 0.93"
New York City: 1.57"
Newark: 1.35"
Philadelphia: 1.11"
Poughkeepsie: 2.08"

Dry weather will prevail through the remainder of the week. Temperatures will generally top out in the middle 70s in much of the region.

Another storm could bring a significant rainfall to the region Saturday night into Sunday.

In the medium and longer range, a warmer than normal pattern could develop in eastern North America as September concludes.

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 -19.79 today.

The preliminary Arctic Oscillation (AO) was -0.331 today.

On September 16 the MJO was in Phase 3 at an amplitude of 1.591 (RMM). The September 15-adjusted amplitude was 1.474 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 83% probability that New York City will have a warmer than normal September (1991-2020 normal). September will likely finish with a mean temperature near 71.3° (2.1° above normal).

The 0z guidance is 3 to 1 in favor of a wet tropical moisture weekend. The Euro, CMC, and UKMET are wet. While the GFS took its turn as a drier model. The CMC will pull off a big win if we get a decent shot of moisture since it has been the most steady model from run to run showing this.

If all the past analogs of 5” or less snowfall seasons for NYC work out, then NYC should at least double the 2.3” from last season.

23-24……?

19-20….4.8

20-21….38.6

63/55 and bright sunshine.  Sunset is 6:59 for most the area for those who like the waning daylight.  Noe stretch of weather the next 96 hours , mid / upper 70s and onshore flow keeping mins up a bit especially once to Thu/ Fri (9/22).  9/23 - 9/26 southerly flow and deep moisture feed keeps it humid, warm and potentially very wet.  Atlantic ridge acts as a block to keep the east in flow and any low that develops will aid in more rain.  Beyond there a bit of a stalled out strung out upper flow with cut off and stagnant flow should keep it overall warm/wet into Oct.  Enjoy the sunshine these next days as it may be very cloudy and west the next week starting Saturday.

1947 - The eye of a hurricane passed directly over New Orleans, and the barometric pressure dipped to 28.61 inches. The hurricane killed fifty-one persons, and caused 110 million dollars damage. It produced wind gusts to 155 mph while making landfall over Fort Lauderdale FL two days earlier. (David Ludlum) (The Weather Channel)

 

1947: A hurricane made landfall near the Chandeleur Islands, LA on this day.  Wind gusts of 112 mph and a central pressure of 967 mb were measured at Moisant International Airport. A storm surge of 9.8 feet reached Shell Beach, Lake Borgne. Moisant Airport field was flooded by two ft. of water while Jefferson Parish was flooded to depths of 3.28 ft. New Orleans suffered $100 million in damages. Total loss of life was 51 people. As a result of this storm, hurricane protection levees were built along the south shore of Lake Pontchartrain to protect Orleans and Jefferson Parishes from future storm surges.  Moisant Airport flooded after the September 19th, 1947 hurricane. The image is courtesy of the US Army Corps of Engineers.
 

1967 - Hurricane Beulah deluged Brownsville, TX, with 12.19 inches of rain in 24 hours, to establish a record for that location. Hurricane Beulah made landfall on the 20th near the mouth of the Rio Grande River, where a wind gust to 135 mph was reported by a ship in the port. (19th-20th) (The Weather Channel)

1987 - Cool autumn-like weather invaded the Central Rockies. Temperatures dipped into the 30s and 40s, with readings in the teens and 20s reported in the higher elevations. Gunnison CO was the cold spot in the nation with a morning low of 15 degrees. (The National Weather Summary)

1988 - Thunderstorms developing along a fast moving cold front produced severe weather in Wisconsin, Illinois, Indiana and Michigan. Eight tornadoes were reported, including five in Indiana. Thunderstorm winds gusted to 74 mph at Wabash IND. Winds associated with the cold front itself gusted to 69 mph at Kenosha WI. (The National Weather Summary) (Storm Data)

1989 - Showers and thunderstorms produced heavy rain in the Middle and Northern Atlantic Coast Region. Cape Hatteras NC was deluged with nearly 3.50 inches of rain in three hours. Syracuse NY reported 1.77 inches of rain, a record for the date, and Chatham NJ reported an all-time record of 3.45 inches in one day. Hurricane Hugo headed for the Bahamas, and Tropical Storm Iris, following close on its heels, strengthened to near hurricane force. (The National Weather Summary)
