On Thursday morning, July 12, 2012 the low temperature at Death Valley, California dropped to just 107°F (41.7°C), after hitting a high of 128° (53.3°C) the previous day. Not only does the morning low temperature tie a record for the world's warmest low temperature ever recorded, the average temperature of 117.5°F is the world's warmest 24-hour temperature on record. According to weather records researcher Maximiliano Herrera, the only other place in the world to record a 107°F low temperature was Khasab Airport in the desert nation of Oman on June 27, 2012. The previous U.S. record high minimum temperature may be a 103°F (39.4°C) observed in Death Valley, California in 1970. The NWS lists a July 5, 1918 low temperature of 110°F as the official highest minimum temperature recorded in Death Valley. This temperature is disputed by Mr. Herrera, who says the temperature that night was not monitored and passed from 60°F to 110°F then to 60°F again.

Wednesday's high of 128°F (53.3°C) was the 10th hottest temperature in U.S. history, and the hottest temperature measured in the U.S. since July 18, 2009, when Death Valley recorded another 128° reading. The only hotter temperatures in U.S. history were all measured at Death Valley, the most recent one being the 129° measured on July 6, 2007. The all-time high for Death Valley is the 134° reading of July 10, 1913.

Temperatures have cooled considerably at Death Valley over the weekend, and the forecast for Monday calls for for a downright chilly high of just 110°. That's sure to be a disappointment for the ultramarathoners in the grueling Badwater Ultramarathon, which begins Monday in Death Valley. Covering 135 miles (217km) non-stop from Death Valley to Mt. Whitney, CA, it is the most demanding and extreme running race offered anywhere on the planet. I'm sure they would have liked to have had the distinction of running their race last Wednesday and Thursday, during the hottest 24-hour period ever recorded on the planet!

If I get this right, I probably wont. But, with all the talk about the cooling in the Pacific means the hurricane season in the Atlantic is gonna be suppressed,right? Otherwise it's gonna be a quite year for us. Have I got this right or am I totally wrong. I've been reading what everyone says and it just sound like it's gonna be very very quite. I know I promise it only takes one to mess everything up. If someone answers me Thank you in advanced.

HURRICANE FABIO DISCUSSION NUMBER 19
NWS NATIONAL HURRICANE CENTER MIAMI FL EP062012
800 AM PDT MON JUL 16 2012

THE EYE OF FABIO REMAINS EVIDENT IN INFRARED SATELLITE IMAGES...
ALTHOUGH IT HAS BECOME LESS DISTINCT AND CLOUD FILLED IN EARLY
MORNING VISIBLE IMAGERY THIS MORNING. DEEP CONVECTION AROUND THE
EYE IS GRADUALLY DECREASING IN COVERAGE AND INTENSITY AS THE
CYCLONE MOVES OVER SEA SURFACE TEMPERATURES OF 23 TO 24 DEGREES
CELSIUS. THE INITIAL INTENSITY IS LOWERED TO 65 KT...WHICH IS A
BLEND OF THE DVORAK T- AND CI-NUMBERS FROM SAB AND TAFB. THE RATE
OF WEAKENING IS EXPECTED TO HASTEN AS FABIO MOVES OVER EVEN COOLER
WATERS DURING THE NEXT DAY OR SO. INCREASING SOUTHWESTERLY SHEAR
ON TUESDAY SHOULD ALSO ASSIST IN THE RAPID DEMISE OF THE
CYCLONE...AND FABIO IS FORECAST TO BECOME A REMANT LOW IN 48
HOURS...IF NOT SOONER.

IT APPEARS THAT THE ANTICIPATED NORTHWESTWARD TURN HAS OCCURRED AS
THE INITIAL MOTION ESTIMATE IS NOW 320 DEGREES AT 7 KT. A WEAKNESS
IN THE SUBTROPICAL RIDGE PRODUCED BY A LARGE MID-LATITUDE TROUGH
ALONG THE WEST COAST OF CALIFORNIA SHOULD CAUSE FABIO TO TURN
NORTHWARD WITHIN THE NEXT 24 HOURS. AFTER THAT TIME...FABIO IS
EXPECTED TO SLOW DOWN AND TURN NORTHEASTWARD AS IT BECOME A
SHALLOW SYSTEM.

SOME MID- TO UPPER-LEVEL MOISTURE ASSOCIATED WITH THE REMNANTS OF
FABIO IS EXPECTED TO SPREAD OVER PORTIONS OF SOUTHERN CALIFORNIA
DURING THE NEXT FEW DAYS.

There is specific definition of severe weather, and the Storm Prediction Center does not have FL in that kind of zone right now. You mean some heavy rain and thunder, which likely won't be severe.

Well, I live here, and although cool summers are common in the UK, this summer has seen unprecedented rain and floods, due to an unusually southerly jet stream.

Wildlife is affected. There aren't enough flying insects for the swallows, martins and swifts to feed their young.


Yes it's called Natural Selection, only the fittest will survive this year, but one poor summer won't proberbly wipe out anything. If it did, tough. Animals are wrongly given Human characteristics by the likes of Disney, but in reality, it can be a grim fight on the edge of survival for each individual and a species as a whole. Just ask the Dodo..... what could be more grim than sitting around, as sailors bonked you on the head, cooked and ate you......

Given that evolutionary adaptation is a long-term process, if the environment changes more rapidly than a particular species can adapt to it, that species will suffer. And that's happening all over the globe right now, not just in the UK.


Not always, some species can adapt, but some can't.

Good Morning. The AussieMet bi-weekly Enso analysis will be out tomorrow morning at it is good at detailing recent trends since their last outlook. Here is their weekly observation from their July 3rd outlook so the one tomorrow morning should detail the past two weeks through this past weekend.

Issued on Tuesday 3 July
Next update expected by 17 July 2012

Weekly sea surface temperatures:

Warm sea-surface temperature (SST) anomalies in the eastern tropical Pacific have increased when compared to two weeks ago. The SST anomaly map for the week ending 1 July shows warm anomalies extend along the equator in a broad band between the South American coast and about 160°W. Tropical SSTs in the western Pacific are near average for this time of the year.

Index Previous Current Temperature change
(2 weeks)
NINO3 +0.7 +1.0 0.3 °C warmer
NINO3.4 +0.4 +0.7 0.3 °C warmer
NINO4 +0.1 +0.2 0.1 °C warmer

SOI is very tough to predict... This recent uptick is a bit more than noise, however, as today marks the 9th straight day of positive daily values with an 8.49.


if it crashes, youll end up not noticing the uptick.
but if you can predict the weather patterns between THTI and DRWN, which i assume have maybe a 7 day forecast, you might be able to see things like this coming.

Quoting MahFL:


Thats a load of bull. Cool summers are not a rare thing in the UK, the wildlife has evolved there to cope with the weather. It's survival of the fittest, those that do survive will make the species stronger in the long run, and if a species does dissappear, then obviously it's not evolved to live there.


Well, I live here, and although cool summers are common in the UK, this summer has seen unprecedented rain and floods, due to an unusually southerly jet stream.

Wildlife is affected. There aren't enough flying insects for the swallows, martins and swifts to feed their young. Perpetually swollen and muddy rivers means that the small water birds, such as kingfishers and dippers, can't catch food, either. And I can't remember when I last saw a butterfly.

In today's Telegraph, there's a prediction that the jet stream may be about to take up its more usual position, between the UK and Iceland.


"Optimistic forecasters hope the heavy rain and floods will improve at the weekend, with sunshine and warm weather finally arriving.

Thunder storms and drizzle could give way to bright sunshine and temperatures in the pleasant early 20s going into next week.

The summer weather is predicted to arrive just as Britain’s schoolchildren begin their holidays, and a few days prior to the Olympics opening ceremony.

The change is understood to be the result of the Atlantic jet stream which acts to separate weather conditions, with sunnier, more settled conditions to the south.

So far, it has been positioned unusually far south for this time of year, explaining why Britain has experienced some of the wettest and coldest conditions on record.

It is now hoped it will move further north this weekend, with more typical summer weather forecast to return to at least the southernmost parts of the country"

new GFS looks like the trough bens back to a cutoff low and then one low comes out dominant, like the ECMWF had.

And i swear this is the longest omega block pattern i can remember. Weve had it since early June if i remeber correctly.

Good morning!

Well, I have to say that the Kingfish Tournament was a little bit of hell for everyone yesterday. That tropical wave rolled in on us about 6:00 a.m. and turned the seas from 3-4 ft. to 10-12 in a number of minutes. Although I did catch a nice-sized barracuda (one of the competition fish), it wasn't enough to win anything. Still, a good time had by all.

Other than that, the sky has cleared up this morning with a nice breeze.

Have a great day, all!

Didn't really take the time to read the article? They have had their wettest April & June on record. Didn't sound like the puffins, birds, bats & butterflies have evolved to make babies in the sort of winds & rain they are having this year. Another bad year for the bees too, they go & most of us go, or we all spend our days pollinating our own food. There is winners there this year..mostly the bane of the garden..slugs, snails, nettles & brambles.

The puffins have tried to evolve & survive in the few areas we have let them be. People nearly whipped them out in the 1800 & early 1900s clubbing them for meat & eating their eggs.
