That area has been the heavy rainfall magnet this summer.

You can classify it as a backdoor since the high is to our NE with a predominant easterly flow. Typical continental cold fronts have mostly NW to N flow behind them without the present marine layer across the region.

Backdoors are usually dry for us with the best moisture convergence to our south.

Several of our stations will finish August near the warmest on record. There were also a number of local stations with a top 5 and 10 warmest summer(JJA). But the high humidity was even more impressive than the temperatures. JFK is at 34 days of a 75 or higher maximum dew point. This is 10 more days than the previous record. It is also a new extreme for 3 consecutive years with so many days. through 8/30: ............AUG....JJA EWR.....#5 LGA......#2......#3 JFK......#5 HPN.....#2......#8 BDR....#2........#3 ISP.....#4........#5

It looks like the winds out there were too light to cause upwelling. NY Harb Entrance 2050 83 77 CALM / 2 1016.2 2/ 6 20 S Fire Island 2050 81 80 250/ 4/ 4 1016.6 2/ 6

Following the brief -NAO/-AO start warming interval, the NAO swung back to record positive levels. Remarkable shift from record negative Jun 2009-Mar 2013.

Amazing record WAR/SST couplet continues. This is what happens when we get a 588 dm ridge with 80 degree temperatures in February. The WAR just keeps reloading.

This is the first winter, spring, and summer with such high temperature departures on the last month of each season. LGA Feb....+7.1....#2...... warmest on record May....+4.9...#2.......warmest on record Aug....+4.5....#2......warmest on record through the 29th

All our stations are in the top 10 warmest Augusts. LGA, HPN, and BDR are currently ranked 2nd with 2 days to go. EWR....#6...79.1 NYC......#9...78.1...blocked sensor artificial cooling issues LGA......#2...80.9 JFK.......#7...77.3 ISP.......#4...76.6 HPN......#2...75.8 BDR......#2...77.9

This has to be the hottest feeling day on the South Shore that I can remember with a SSW flow. Wantagh is 89/77/101. Days here in the past with a HX over 100 usually had more of an offshore flow. This is like a Miami sea breeze directly off the Gulf Stream.

Long range models including the EPS continue to underestimate the strength of the WAR. Notice how the ridge is getting stronger for next week the closer in we get. old run new run

If BDR can hold its 78 minimum through midnight, then it will have the 3rd warmest also. #1...80...2013...2002 #2...79...2006 #3...78...2018...1995...1975

3rd highest minimum temperature on record for LGA at 84 degrees. This is the first time that a minimum this high occurred this late in the season. Warmest minimum temperatures on record for LGA: #1...86...2013...2006...1999 #2...85...2011 #3...84...2018...2016...2010...1966...1952

The 98 at LGA was the highest temperature of 2018 so far. Wonder when the last time was that LGA had a yearly max so late? MAXIMUM 98 225 PM 99 1948

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
