Death Valley's 113°: hottest April temperature on record in U.S.
An unprecedented April heat wave brought a second day of sizzling temperatures to the Western U.S. yesterday, where temperatures ranging 20 - 30 degrees above normal have toppled numerous all-time April heat records. Nearly every weather station in the Inter-mountain West has broken, tied, or come within 1 - 2 °F of their all-time record April heat record since Sunday. Most notably, the 113°F measured at Furnace Creek in Death Valley, California on Sunday, April 22 was tied for the hottest April temperature ever recorded in the U.S. According to wunderground weather historian Christopher C. Burt, the hottest reliable April temperature ever measured in the U.S. was 113°F in Parker, Arizona in 1898. A 113°F reading was also taken at Catarina, Texas in April 1984, and at Greenland Ranch in Death Valley on April 24, 1946. A hotter 118°F reading measured at Volcano Springs, CA in April 1898 is considered unreliable, since we don't know much about the exposure conditions or if the thermometers were even in shelters at remote California desert stations back in the 1880s and 1890s. The previous hottest April day in Death Valley was 111°F. Yesterday, the high temperature in Death Valley "cooled off" to 110°F, merely the fourth highest April temperature ever measured there. The heat wave peaked Sunday and Monday, and temperatures will be closer to normal for the remainder of the week.

As is often the case when a major Nor'easter is affecting the Eastern U.S., the record-breaking heat is due to a contortion of the jet stream that has created a strong ridge of high pressure over the Western U.S. Wunderground's extremes page lists 56 stations in the West in the past four days that have tied or broken all-time heat records for the month of April, including:
Phoenix, Arizona: 105°F (previous 105° April temperatures occurred on 4/20/1989 and 4/29/1992)
Las Vegas, Nevada: 99°F (tying old record set 4/30/1981)
Reno, NV: 90° (old record 89° 4/30/1981)
Elko, NV: 87° (old record 86° 4/30/1981). This also beat the previous so-warm-so-early-in-the-season record by 4°
Ely, NV: 84° (old record 82° 4/28/1992)
Winnemucca, NV: 90° (tying old record set 4/30/1981)
Grand Junction, CO: 89° (tying all-time April record also set on 4/29 and 4/30, 1992)
Boise, ID (91°) and Salt Lake City (88°) both came within 1°F of their record April max.

Late-season Nor'easter winding down
The powerful late-season Nor'easter that brought snow, high winds, and heavy rains to the Northeast yesterday is winding down as it moves northwestwards into Canada. The storm brought an unusual amount of snow for so late in the season to western Pennsylvania, western New York, and the higher elevations in West Virginia. An earlier report posted by the NWS of 23.7” at Laurel Summit, Pennsylvania (elevation 2,770’) has now been scaled back to just 13.7”, according to the latest NWS Storm Summary. Many other higher-elevation locations saw snowfall amounts in the 6 - 12 inch range. Snow amounts were considerably lower in the major cities of the region; Buffalo, New York got 0.9", Rochester, New York, 2.8", and Erie, Pennsylvania, 0.5". The wet, heavy snow fell on regions where trees had already come into leaf, thanks to the surprise "Summer in March" heat wave that brought 80° temperatures to the Northeast over a month ago. High winds that accompanied the heavy snow caused extensive tree damage and power outages to at least 75,000 people in the region. However, the storm may have done more good than harm--widespread rainfall amounts of 2 - 4 inches occurred across Massachusetts, Rhode Island, New Jersey, Connecticut, and Southeast New York, which is under moderate to severe drought. Rainfall deficits in the region were generally 5 - 10 inches, so the Nor'easter's rains will make a significant dent in the drought. Wunderground's weather historian Christopher C. Burt has updated his post on Record Late Season Snowfalls with information from this storm.

The house is located at the north or south pole.
How do you walk south from the south pole?
I liked my answers better :)
Night all
Considering the north pole is ice? I guess south
I feel dumb

I'll save it for Hurricane season.
Somebody giving us something to play with. Cool.....
Hey Nigel....

Storm Relative 1km Geostationary Visible Imagery
whats up pedley?
Just kicking back waiting for something to happen.
I see that we may get a western pacific storm
That's no moon...
Yes, we need something for amusement.
How are you aspectre?
Agreed...have you seen TWC predictions for the hurricane season?
Sounds more like a path to integrate along using line integration techniques to me.
I saw the ones they mentioned earlier. I am thinking 12/6/2 for Atlantic
and 16/10/6 for EPAC
Reasonable numbers for the atlantic if we get an el nino, but I think we would also have more storms in the pacific
Yup, that one is probably under. These are my first attempts at a prediction.
What storm is that on your Avatar?
If el nino is non-existent or occurs late in the hurricane season, then those numbers for the pacific maybe spot on
That's hurricane Ivan
Says who?
What's up Keeper...can you share the link to these images?
*2 Years Later* Professor: Microbes in Gulf attacking things other than oil? Very large increase in crab and lobster with appendages falling off — High incidence of eyeless shrimp… More (VIDEO)
Published: April 23rd, 2012
Title: Gulf Oil Spill: BP Execs Escape Punishment as Fallout from Disaster Continues to Impact Sea Life
Source: Democracy Now
Date: Apr. 23, 2012
AMY GOODMAN: [...] The impact of the disaster continues to unfold for the area’s residents and wildlife. Scientists say shrimp, fish and crabs in the Gulf of Mexico have been deformed by chemicals released during the spill. One commercial fisherperson told Al Jazeera that half of shrimp caught during the last white shrimp season were eyeless.
SCOTT EUSTIS: We have some evidence of deformed shrimp, which is another developmental impact, so that shrimp’s grandmother was exposed to oil while the mother was developing, but it’s the grandchild of the shrimp that was exposed grows up with no eyes.
[...]
DAHR JAMAIL: We have recently come across very, very disturbing information from Gulf region scientists. You know, the first person I came across was Dr. Jim Cowan with Louisiana State University, and he’s been working on a project, getting his funding from the state of Louisiana Department of Wildlife and Fisheries. And he’s been, actually, for many decades, sampling red snapper, which is a very popular fish in the industry. And he’s been finding that before the BP disaster in April 2010, that of all the red snapper he was sampling, he was finding point-one-tenth [0.1] of 1 percent snapper coming up with lesions and other types of problems. Post-spill, that has gone to between 2 and 5 percent of all samples. That means an increase of between 2,000 and 5,000 percent, and in some areas as much as 20 percent [a 20,000% increase], he said, in other areas who have extreme impact, where the oil and dispersants came in nearby the shore, of as many as 50 percent [a 50,000% increase] of fish sampled. Very, very disturbing information there.
And then, another doctor that I spoke with, Dr. Darryl Felder with University of Louisiana-Lafayette, he also has before-and-after samples. He was working out around the Macondo wellhead area on the sea floor with a grant from the National Science Foundation, that they wanted him to investigate just overall drilling impact on species in the area. And so, he had deep sea crab, deep sea lobster, deep sea shrimp, from before the spill, and then many, many sampling trips after the spill. And what he found was obviously a very, very large increase of finding crab and lobster, etc., that had black gills, that had appendages falling off, again similar stains on their shells, and again similar to findings not too different from Dr. Jim Cowan’s, in that when the oil, that much unnatural oil introduced into the environment, coupled with the dispersants, that it’s causing these lesions that are burrowing into the carapace and the shells and eating into the wax of the shells, causing an increase in the microbes that do eat oil. Not only are they not eating just oil, but eating into the shells, and then parasites and diseases and other illnesses are being formed.
And then, lastly and I think most disturbingly, as you already touched upon, the eyeless shrimp. We’re seeing very, very large incidence of eyeless shrimp now popping up not just in Louisiana, but in Alabama and Mississippi, not just inshore, but further far ashore—offshore. And some of the shrimp that we’re seeing, they came from a shrimper in Louisiana that was caught—caught 400 pounds of white shrimp in one catch in last September, just off the outskirts of Barataria Bay. And that was—of the 400 pounds of shrimp, the shrimpers told us that all of them were eyeless. So, very, very disturbing findings. And unfortunately, we’re expecting more to continue.
[...]
[BP claims administrator Ken] Feinberg is on his way out, because so many people across the region are incensed at the way he’s handled most of the claims. [...]
I talked to Ryan Lambert, who heads one of the largest charter fishing businesses in the entire Southeast, and he said, “Hey, we’re going to court. They have destroyed my business. It’s not coming back. I haven’t seen one single speckled trout in three months. It’s the first time I’ve ever experienced that in my life. That’s 90 percent of the fish that we catch. So of course I’m going to go to court, because what they offered me, frankly, was insulting.”
