July 22, 2011: A day of records
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.

Interesting. Would love to have a geologist or someone educated in the field weigh in on this.
From Wiki:
Pisgah Crater, or Pisgah Volcano, is a young volcanic cinder cone rising above a lava plain in the Mojave Desert, between Barstow and Needles, California in San Bernardino County, California. The volcanic peak is around 2.5 miles (4.0 km) south of historic U.S. Route 66-National Old Trails Highway and of Interstate 40, and southeast the town of Ludlow.

dont make me turn this care a round
High Pressure to the NE will drive 90L on W-WNW course! Just my opinion of course!
agree it looks like its heading for the bahammas and might get relocated abit north imo whatever it is its becoming larger size
If you have a system with a closed low at the surface, you have a real heat engine. Without this, you have a collection of thunderstorms.
Not sure specifically, but recent SST changes (warming, despite regular upwelling) in the California area have resulted from the partial blocking of the California Current by a warm anomaly near the Pacific Northwest.
For unconfirmed result of a scientific study linking phytoplankton chlorophyll-a blooms to upwelling potentially preceding earthquake activity, see link: Plankton blooms linked to quakes
Also, to me it doesn't really look like a volcanic eruption. Think that guy may be full of it. Couldn't see it on Sat imagery either.
It's past 90's bedtime, he needs his beauty rest. He'll wake up at around, say noon tomorrow, have some coffee and we'll repeat today tomorrow.
Don't believe I've every spent more hours on a wave.
Well, cliffhanger pre-Don needs his DMAX beauty rest (!) and so do I. Nice having a system on your own circadian time, instead of opposite!
DMIN and DMAX apply to almost any form of oceanic convection, with the exception of mature tropical cyclones.
Clutter, wildfire, or stationary precipitation?
If they do, I highly doubt it will be toward your general direction.
The user asked a question in regards to a video he saw. I get your gig on the blog with all the humor and doom etc, but you come off as a ....(insert own word) with comments like that.
I think it's just clutter. Doesn't appear to be originating from a particular source.
Don't think this would support precip.
Daggett-Barstow, CA
Temperature
102 °F
Dew Point 33 °F
Hard to tell. Could be wildfire. And there's a lot of military training in that general area, Twentynine Palms and Fort Irwin being the largest.
I get that sometimes certain entities will hide things for different reasons. But sometimes an absence of news is simply an absence of news. You know?
Surface pressure near the area of strongest 850 mb vorticity is close to1016 mbs . There is little chance of 90L developing any time soon.
whats the chs are that 90L will this fall apart
Ah, okay. I agree in that case. But I wasn't saying that storms could not rapidly intensify in the area that the other poster specified. I was merely saying that as of now, conditions are not supportive of rapid intensification.
I also noticed the military bases when looking around in google earth. BTW neo here is another one you can add to your list of all time temps being broke with this heat wave, this one dating back to 1926. ~7 mies from my house if you missed it earlier.
103 degrees: Record high in Merrimack Valley
It reached 103 degrees at Lawrence Municipal Airport yesterday, breaking the previous record high temperature for the Merrimack Valley by one degree.
The previous record of 102 was set on the same date in 1926, according to Haverhill native Matt Noyes, a New England Cable News meteorologist.
"As best I can tell, this does go down as the hottest temperature of all time — on record — at the Lawrence airport," Noyes said.
Evening kman. Agree strongly. No development until it reaches the western Caribbean or Gulf of Mexico.
I think he meant more along the lines of making it difficult to track. After all, if it doesn't show up well in the global model fields (such as was the case with Bret), then it becomes harder to forecast.
Divergence associated with an upper low over the western Caribbean. Divergence is an excellent source of convection, but it is hardly the determining factor.
Testing...radial velocity.
(perspicacious individual?) (pan-dimensional being of liquid helium metabolism?) Who is going to put buffoon in parentheses in regards to themselves, taking in to account the comment to which you object? I find it humorous that the video implies a conspiratorial "blocking of feeds," as it were. If there is a lack of continuity in supporting evidence for a geological- specifically volcanic- event, I would take that as substantial evidence that it is not in fact a serious, if even actual, event. The USGS would be all over it. USGS Volcano Alerts. As you can see, they are not; there is no event.
Before the update I gave 90L 10%. That was the number the NHC gave it.
The rotation at the 5000 foot level has not translated down to the surface but might do so in time IF the wave axis can avoid Hispaniola. I never look for development of weak waves in the Caribbean until they pass 75W. With this one I think the odds for development in the Caribbean are low. If it can stay close to or South of Jamaica then perhaps it might stand a chance in the NW Caribbean.
For now, the cloud tops in the convection are warming which is a sign of weakening. There may be flare ups over time, like early tomorrow morning, but I do not see this feature as a short term threat.
I agree. Surface observations across the islands supported a developing low this time yesterday.
Also noticed on the vorticity map someone posted earlier that the NWly portion of the wave's vorticity seems to have faded somewhat while the SE area seems to have increased in vorticity. I have a feeling if 90L ever pulls that vanguard of vorticity and Tstorms into a centre, we'll finally see development.
Right now, looking like Inagua and the TCI will get some rain starting later tonight...
Curious for sure:
