The crest of the extreme heat wave of July 2011 has passed, although temperatures are still going to be dangerously hot in the Mid-Atlantic and Northeast today. New York City (Central Park) will reach 100° again, as well as Philadelphia and possibly Washington Dulles. Heat index values could surpass the 110° mark today, and excessive heat warnings are in effect from New York City to South Carolina, as well as a large portion of the Central United States. Yesterday, the heat index soared past 120° in Wilmington, DE (124), Easton, MD (125), Annapolis, MD (120) and Atlantic City, NJ (122), among others. A more complete list of Friday's heat index extremes can be found here.

Numerous records fell yesterday as far north as Maine. There were plenty of daily records to talk about, but here are some of the noteworthy all-time record high temperatures:

Newark, NJ: 108° (old record was 105° set in 2001)
Washington Dulles, DC: 105° (old record was 104° on multiple dates)
Bridgeport, CT: 103° (ties the old record set in 1957)
Hartford, CT: 103° (old record was 102° set on multiple dates)
New Haven, CT: 102° (old record was 101° set in 1926)

Baltimore hit 106°, one degree shy of their all-time high record which was set in 1936. New York City (Central Park) set a daily record of 104°, which was 2 degrees shy of their 106° all-time high record, which was also set in 1936. More on the record-setting year of 1936 in yesterday's blog from Jeff. Two notable all-time record high minimums were also set yesterday: 84° in New York (Central Park) and 86° in Newark, NJ.

Our weather historian, Christopher C. Burt, keeps track of 303 select stations in the U.S. with long standing record histories. So far this summer, seven of these have broken or tied their all-time maximum temperature records. Some of these were long-standing:

• Amarillo, TX 111° (1892)
• Dodge City, KS 110° (1874 tied)
• Newark, NJ 108° (1893)
• D.C. Dulles 105° (1962)
• Tallahassee, Fl 105° (1883)
• Hartford, CT 103° (1885)
• New Haven, CT 102° (1780)

The last summer to have more all-time high records than this year was 2002, which set 9. Christopher C. Burt estimates that yesterday probably rates in the top five hottest days on record for the mid-Atlantic states (Washington D.C. to Boston).

Invest 90L


Satellite imagery of NHC Invest 90L this morning.

Invest 90L is looking ragged on satellite as it makes its way across the Caribbean islands. While this wave looked ripe for eventual development earlier this week, it has really taken a turn for the worse as it moved across the Main Development Region of the North Atlantic. Today, low level circulation is could favorably be described as less than moderate, and almost nonexistent at higher levels. Today, not one of the global models I've looked at (ECMWF, NOGAPS, CMC, UKMET, or GFS) develop 90L, but they are coming into better agreement that the wave's track will be across the Caribbean islands and into the Gulf of Mexico, rather than up the east coast of Florida. This could be one of the reasons the models are not suggesting development—too much land interaction, not enough time over open warm waters. However, its hard to say that this wave will not show some signs of improvement when it reaches the Gulf. Water will be toasty, moisture will be relatively high, and wind shear will remain incredibly low. Today the National Hurricane Center is giving this wave a 20% chance of development over the next 48 hours. My forecast has been the same for the past two days, right around 20% chance of development over the lifetime of the wave.

Thanks to our weather historian Christopher C. Burt for some useful information on heat waves and yesterday's records. I'll have another blog on Monday.

Well, I hope we do a bit better... lol

On the JFV conversation, I'm suggesting if u have a problem with a blogger, use the post related buttons. I'm about ready to start [-] everybody who keeps talking about JFV again. It's a really unnecessary distraction...

I thought JFV was JrWeathermanFL?
I don't know how he is doing it but I think he is coming on using different names and whoever it is that thinks he hasn't been on for about a year need to rethink that one. He is on just about every day.

You seem to lose power a lot. Is the power grid there that unstable?



More so in the summer, when we end up "load-shedding" because everybody turns on their a/c... however it's been worse than usual recently because the current administration here took a laisse fairez attitude towards upgrades, and then the recession hit us too. So stuff that should have been done 3 years ago is still not working...


Ah, that sucks.

If 90L were to develop in the Gulf, I would think that the current ridge of high pressure over the Gulf (see link below) would take it off to the West towards Mexico or Texas but that is pure speculation on my part at this early juncture.

Who is that renamed JFV?

The thing is that every time that JFV comes around, the blog gets affected..


In the "Barrio", Brooking NY, JFV was "Jaimito Fuma Veneno", a drug addict that everybody knew and helped by giving him food. He was killed in 1988..

Look Ladies and Guys,
I just donot think we need to write off 90L just yet...
I'm thinking when it gets to the Gulf its going to explode... Yes as of right now it is a Tropical Wave but how many of these types of storms just go crazy after looking like this.... "A Bunch"

So keep your eys on this one because he is not done yet....


Taco :o)


I don't think it'll explode per se, since its circulation is very diffuse. However, I do think it is most prudent to keep an eye on it.

but so far only one small shower earlier today.

You guys got the dry side... lol... we're starting to get squally wx now... dunno how long it will last, though. This is one weird wave...

So then is that the end of 90L. Or does this thing have a chance of resurfacing?


Personally, I think that it has a chance of re-surfacing

I would prefer SAL inhibiting TS formation, than a SAL contaminated atmosphere in the Atlantic..
It can give you alegies, but you have the means to lower the impact; but a Hurricane can kill you or your loved ones, destroy your belongings, destroy your business, get you unemployed, make you broke etc....

The wave has held together incredibly well in spite of the land issues and I would not count it out if it is able to re-fire convection as it starts to exit Cuba but I have not checked the longer-term models today on the wave.


It definitely still has a chance.

Dude are you nuts? The lack of SAL has actually partially ruined my summer because there is more humidity, so more rain showers, so less beach days. >:\

90L or whatever is left of it, has moved way to far ahead of schedule, this thing is nearing Jamaica, this thing will be in Gulf by Tuesday, which is way ahead of what models were saying last week. My opinon, not a damn thing is gonna happen.

Good evening folks. Noticed when I signed on The WU page took down 90L, but noticed Keep posted a revised position and image for the invest. I guess it is still holding on.

JP, please do not complain, cause lack of SAL is a very good thing, my friend. Keep in mind that SAL retards TC formation and growth!

Correct. Any development will be slow.

Getting our first showers from 90L here... some light wind gusts blowing the rain around.

If I suddenly "disappear", you can guess I lost power... lol

I think that 90L could have developed by now but for the location (land interaction) which has prevented significant organization. Even now, sheer is relatively low ahead of it per the latest CIMSS chart for time being but that geographical window happens to be located right over Hispanola and Cuba where the wave is headed.......As such, I agree with the current call by NHC.

are you crazy... we dont want tropical storms we want to have a record season... record low that is


I beg to differ, actually. I'd love to have a very active season, provided the storms stay out to sea. Last year was excellent in that regard.

If I ever have to experience a season like 1914, where only one storm develops, I think I'll die. :(
