Heat without storms is boring. Same with cold without snow. 

You have to remember, unless you want a sticky insane Florida like climate, you cant have storms every day.  Record heat for 2 weeks followed by a big storm outbreak is the best of both worlds.  Storms every 2 weeks is fine as long as it's 100 degrees in between.

These record ridges have ushered in an era of over the top heatwaves. Notice how the warmest departures this month have been NW and NE of the Long Island South Shore. Boston is in track for its warmest June on record. Last summer areas from LGA to New England had there warmest summer on record with a similar pattern in 2018. So even though places like JFK miss the top heat with more southerly flow, the real feel with the record dew points makes it feel as hot or hotter than the hottest summer days in the 100s.

I still find it amazing that LGA was hotter last summer than in 2010 even though they had nearly twice as many 90 degree highs in 2010.  I wonder when we'll have 50-60 90 degree days.

I think you and Don said that within 30 years the excessive heat will overcome the southerly flow and we'll all be hitting 100 multiple times even with a southerly wind?

The average high temperature last summer at LGA just edged ahead of 2010 by a few tenths of a degree.  LGA did better in 95°and 88° days than 2010. So it was able  to overcome the 90° day deficit.

Thats amazing because I look back at last summer as fairly bland.  We didn't have a real historic stretch of heat like the 3 days out of 4 over 100 in July 2010.  I also remember using the a/c far more in 2010.

Do you think we'll get enough climate warming to eventually overcome southerly flow and hit 100 consistently across the area regardless of wind direction?

Season of the Western Atlantic Ridge commencing.  The heat is on and humidity.  Florida weather for the next 5 days Sun (6/27) - Thu (7/1).  Pop showers and rain could out some heavy amounts scattered around the area over  the next 5 days.  Look for sun showers too.  But while sunny temps low to mid 90s and perhaps upper 90s in the warmer spots.  Dewpoints in the low 70s or higher should yield lows in the upper 70s and 80s in LGA, NYC, JFK potentialluy.  Winds will be mainly S-SW. 

GFS and ECM now a bit more aligned as the W Atlantic Ridge pushes east with subsequent front in the 7/2 - 7/4 period.  Right now both clear the area by late on  Saturday (7/3) and allow for a mainly dry warm/nice Jul 4th.

 

Beynond there heights resume to build as ridging builds back into the East coast and we may be soaring again with heat and humidity by the 8th.  Overall warm to hot but plenty of precip mixed in between.

Hopefully last night's Euro was correct with the idea of drying us out even in time for saturday the 3rd. After the lousy Memorial Day weekend, hopefully we can have a dry July 4th weekend. Obviously it's still early and very questionable though.

July 2020 at LGA doubled the number of 95 degree days that they had in 2010. Only July 2011 had more 95° days at Newark. Our airport stations are right in the water. So they are prone to local sea breezes. The dominant westerly flow in 2011shut down the Newark bay breeze so they set a record of 13 days above 95° that July. The ASOS at LGA is right on the water which gets cooling breezes with W to NW dry heat flow. Last summer was the opposite. Newark had SSE bay breezes while LGA got more hot S to SSW flow. Since LGA is North Shore location, it was much warmer than JFK which had cooling southerly sea breezes. That S to SW flow really heats up at LGA as it comes across Brooklyn and Queens and slightly downslopes off the moraine.

One could argue that westerly flow causes our biggest heat outbreaks and that the onshore flow happens because there are weaknesses in the ridge.  I've seen when the high is really strong it overcomes sea breezes which is when we get our best heat.

Do you actually rank 2020 higher than 2010 though?  2010 was basically our 1995-96 of summers for the most heat across the entire region (we are after all a coastal region) and was also the hottest summer on record by summer average.

I'm not sure how representative LGA is of our area because of its cramped congested location, I'd rather use an average of all the airports.  And if you judge summers by peak heat, I dont see any 102-103 temps like we had in 2010 and 2011, which is a true indication of how dominant a ridge is. 2010 is like MJ and 2020 is like Lebron.  Sure Lebron had a longer career but at his best MJ was a better player.  

I actually think EWR is more representative of our area than LGA, because the years in the EWR list are more of what I remember as being extremely hot.  All the summers prior in the EWR list are what I would call extremely hot.

The average of all the airports and COOPs in the NY Coastal Climate division came in at 2nd place behind 2010.

Heal fast and thorough, RE. You have plenty of fine posts ahead of you. As always ……

Thank you I had my belly button hernia done and it’s not an easy surgery but it’s done now and I’m happy I did it. Though I wish I did it during spring or fall. But my job didn’t let me do that so here I am. Outside again very nice under the shade with a bit of a breeze. Currently 88 degrees!

So the summary today,for our subforum is GFS/EC bust,  HRRR/RGEM rainfree being correct.

 

No other changes to the outlook through July 5.  12z GFS iso 7" nr Long Branch NJ and EC up to around 3+. in parts of the forum. 

Let's see what happens...  iso max 3.5?  or more like max 4.5"+?
