First 80 degree dew point at Shirley today since at least 1999.

You know it's a hot and humid pattern for late August into early September when we can only get 2 days of cooling behind a backdoor.

First time since 1973 that LGA reached 97 degrees on or after 8/28. The 2010 late season heatwave only made it to 96.

The 95 at LGA is getting closer to the record. 99...1948 98...1953 97...1973 96...1993 95...2018...through 1 pm.

The 80 degree dew point at Shirley gives a 104 heat index. Shirley FAIR 88 80 77 S6 30.06S HX 104

The heat index should top 100 degrees later this morning into the afternoon. Newark/Liberty FAIR 83 75 77 SW6 30.05F HX 90 LaGuardia Arpt FAIR 85 72 65 NW3 30.05S HX 91 Shirley FAIR 82 78 88 SW6 30.05F FOG HX 91

The windows were fogged up again here this morning. JFK upped the record to 32 days with a maximum dew point of 75 degrees or higher.

High humidity and August being the warmest month of summer has been our new pattern since 2015. LGA warmest month of summer since 2010: 2010...Jul 2011...Jul 2012...Jul 2013...Jul 2014...Jul 2015...Aug 2016...Aug 2017...Jul 2018...Aug

The 90 at LGA makes the 31st day so far this year. That is the 5th highest number of days on record. #1...48 days....2010 #2...35 days....2002 #3...34 days....1991 #4...32 days....2016 #5...31 days....2018...1983

Filtered sunshine today through a layer of smoke.

Euro and GFS slowed down the frontal passage so the heatwave extends into Thursday.

The NAM has near record heat index values for the last week of August.

Several local stations already close to the warmest August on record before the big heat this week. Local August heat rankings through 8/25: EWR....#8....78.5 LGA.....#3.....80.3 JFK......#10...76.9 ISP......#4......76.3 BDR.....#2......77.5 HPN.....#3......75.3

Interesting pattern since meteorological winter of the last month of each season having the warmest departure. LGA Dec...-2.0 Jan...-1.5 Feb...+7.1 Mar....-1.4 Apr.....-3.3 May..+4.9 Jun...+0.7 Jul....+2.4 Aug..+3.6 so far

Someone shot a great video of the derecho from a Brooklyn marina.

Still stands as the most intense derecho to sweep across Long Island. I would rank it as the #1 severe thunderstorm event out here. It was the only time that I experienced severe wind and hail with a nearby tornado. Never saw it get as dark so fast between 2 and 3 in the afternoon before.

Hard to believe that it has been 20 years. An intense line of severe thunderstorms oriented from north to south developed during Labor Day afternoon ahead of a strong approaching cold front. As the storms moved east at 40 to 50 mph, they produced high winds, large hail, and an isolated tornado. Wind gusts from 60 to 80 mph downed many trees and power lines throughout the area. The cost estimates of damage included above are preliminary figures submitted by the Nassau County Office of Emergency Management. In Richmond County, the following peak wind gusts were reported: 80 mph at Great Kills, the Verranzano Bridge, and in Richmond. High winds downed trees and caused a building to collapse in Richmond. One tree fell on and injured a man in Richmond. In New York County (Manhattan), high winds caused a building to collapse. In the Bronx, high winds downed a tree that fell on 3 people resulting in 1 death and 2 injuries in the courtyard of the Edenwald Houses at 1135 East 229th Street. In Kings County (Brooklyn), high winds downed and uprooted several large trees. One tree fell on and injured a person at East 229th Street. Five to 6-foot diameter trees were uprooted east of Coney Island in the Gerritsen Beach Section, where 3 funnel clouds were also sighted and a firefighter was injured from large hail. Large trees also fell on and damaged cars in Bensonhurst. In Queens County, a peak wind gust of 62 mph was measured at both LaGuardia Airport and at JFK Airport. In Nassau County, the following peak wind gusts were reported: 75 mph in Farmingdale, 60 mph in Port Washington and Mineola and 58 mph at Farmingdale Republic Airport. High winds downed large tree limbs at Rockville Center, Baldwin, and Oceanside and downed trees in Long Beach, Massapequa, and Valley Stream. One-inch diameter hail dented cars and covered the ground in Farmingdale. In Suffolk County, high winds overturned many boats in the Great South Bay, downed large trees in West Babylon and Rocky Point and downed large tree limbs in Wading River. One person died when a thunderstorm wind gust capsized a 19 foot sail boat in Great South Bay near Copiague. A Centerport woman, 36, and her daughter, 3, were injured when a tree fell on them in the parking lot of the Ground Round Restaurant and CVS on Fort Salonga Road. The following peak wind gusts were reported: 72 mph in Babylon and 65 mph in Fire Island. Event Narrative The NWS confirmed that an F2 tornado was responsible for significant damage that occurred in Lynbrook. Most of the village received damage from straight line winds up to 80 mph, that was associated with a severe squall line. Downed trees covered the village with some structural damage where the F2 tornado touched down. The major path of damage was from the northwest section of Lynbrook east-southeast to the southeast section of the village. Funnel clouds were observed from near the intersection of Marshall Ave. and Burtis Street and to the southeast. A tornado was first sighted by two eyewitnesses on Hampton Place. It rose and touched down several times: Second, near Winter Street and across Glover Circle; Third, along Peninsula Blvd. between Earle and Benton Avenues; and Fourth, as a weak F2 near the intersection of Rocklyn Ave. and Merrick Road. It moved across the Long Island Railroad Tracks and Sunrise Highway before it finally dissipated. More than three hundred trees were blown over, many on houses and cars. Six people received minor injuries. Four of these were in "The Fun Zone" on Rocklyn Avenue. One woman was slightly injured by a tree that fell on her car. One police officer was also injured.

You know it's going to get hot this week when both the Euro and GFS MOS have mid to upper 90's. The heat index will go over 100 with the dew points in the 70's. Closer to normal temperatures expected for next Thursday through Saturday behind the backdoor cold front.

This would disqualify the NYC ASOS. The NWS needs your help documenting the record breaking rainfall event. We are having trouble finding a rain gauge that captured the event located in a good location, away from bldgs and trees. Anybody know a friend that measured 12+" of rain the other night? #DCFloods#wiwx View details · The general rule of thumb is that the gauge should be twice as far from an object as that object is tall. We are looking for locations from Middleton and West Madison to Cross Plains. Please help us document a new state 24-hour rainfall record. #DCFloods #wiwx #swiwx 5:11 PM - 23 Aug 2018

Enjoy it. That is a great beach to miss the weekend crowds. Today was our one big radiational cooling morning for the whole month.

In addition to top 10 August warmth, several of our stations are in the top 10 warmest of all summers on record through 8/22. 6/1-8/22 rankings LGA....#5....77.6 BDR...#5....74.1 ISP....#5....73.4 8/1-8/22 rankings LGA....#5....80.9 BDR...#2....78.3 ISP....#3....77.3 HPN...#4...76.2 EWR...#9..79.2 JFK.....#9...77.6

June-July 2009 and February 2015 were the rare extreme cold outliers over the last 10 years.

The tropical pattern this summer was tough on businesses at the shore. Constant rain playing havoc with local summer businesses. @clarkfourakerreports cbsloc.al/2Mprhgw 1:34 PM - 19 Aug 2018 Constant Rain Playing Havoc With Local Summer Businesses Most weekends this summer have been punctuated with precipitation, vast amounts of rain that have ruined plans. It has also dampened profits for business that rely on the summer rush.

The near to record WAR/SST couplet continues until further notice.
