Weather Extremes Wither and Fry LA, Drown Texas*

LOS ANGELES (AP) -- Barring a surprise arrival of the kind of gully
washers Texas is getting these days, Los Angeles' driest year in 130
years of record-keeping will go into the books this weekend.
The nation's second-largest city is missing nearly a foot of rain for
the year counted from July 1 to June 30. Just 3.21 inches have fallen
downtown in those 12 months, closer to Death Valley's numbers than the
normal average of 15.14 inches.
And it's much the same all over the West, from the measly snow pack and
fire-scarred Lake Tahoe in the Sierra Nevada to Arizona's shrinking Lake
Powell and the withering Colorado River watershed.
The weather that's withering Los Angeles and drowning Texas are
connected, said Bill Patzert, a Jet Propulsion Laboratory scientist who
researches the ocean's role in climate variations and has watched a
Western drought grow for seven years.
Stationary high pressure has pushed the moisture-bringing jet stream to
the north, which has also allowed moist air to linger over Texas, he said.
"This last year it's definitely like the nail in the coffin," Patzert
said of California's drought. "This is where the pain really comes home.
One of these droughts - you kind of creep into it slowly - and it then
takes a long time to get out of it."
Los Angeles has already called for a voluntary 10 percent cut in water
use, and in recent months its Fire Department has faced wildfires more
typical of fall, including one that left its vast Griffith Park glowing
like a giant barbecue in the middle of the city.
In suburban Pasadena, firefighters recently sprayed fire retardant in
brushy areas around the Rose Bowl, which hosts an annual Fourth of July
fireworks show.
"At this point I don't know why every city in Southern California is not
banning fireworks for the Fourth of July, because we have never been
this dry this early," Patzert said.
Los Angeles could escape the record if sometime in the last hours of
Saturday it gets a dose of Texas weather.
The Lone Star state has had one of its wettest springs after
back-to-back years of record drought. As of Friday morning, 10.97 inches
of rain had fallen for the month at Dallas-Fort Worth International
Airport. That's only a half-inch short of what fell in June 1928, the
rainiest month on record.
The weather extremes have a common thread, Patzert said: the jet stream.
"Although we had a lot of storms in the Gulf of Alaska this winter, we
had just a big, stationary high-pressure system either offshore or to
the east of us, and really what it did was it just drove that
rain-delivery jet stream into the Pacific Northwest and just totally
bypassed us," he said.
The circulation of high pressure also tends to cause Southern
California's Santa Anas, the dry, warm winds that descend out of the
high desert north of Los Angeles and are often linked to terrible fires
in fall and winter. In the past year there have been three times the
normal number of Santa Ana days, Patzert said, and a "more or less
continuous fire season."
"The devil winds gave us the diva of drought," he said.
The shift in the jet stream to the north has also kept rain over Texas,
he said.
"Usually the jet stream tends to move these things along," he said.
Last year was Texas' driest ever, with more than $4.1 billion in crop
and livestock losses and deadly wildfires that ravaged a record 2
million acres. But many praying for rain a year ago now are screaming,
"Enough!"
The central Texas cities of Austin and San Antonio have received nearly
twice as much rain as usual for June. And earlier this week, about 18
inches of rain fell overnight near Marble Falls, about 40 miles
northwest of Austin. Boats and helicopters rescued people who scrambled
atop buildings and vehicles.
Even typically parched west Texas is getting drenched. So far this year,
Lubbock had received 17.39 inches of rain - just over an inch shy of the
amount it usually gets during the entire year.
"It's pretty rare to see that much rainfall in a half year, but it's
been happening across Texas." Mark Conder, a meteorologist with the
National Weather Service in Lubbock.
The Jet Propulsion Laboratory's Patzert, who is best known for
explaining the ocean warming and cooling phenomena known as El Nino and
La Nina, said such deluges do little to recharge aquifers because the
water runs off too quickly, compared with the slow melting of snow packs.
In California, he said, the drought situation resembles the 1950s and
'60s rather than the unusually wet '80s and '90s, and it's not going away.
"I think last year, unfortunately, people should plan on that as a
preview of coming attractions, because there are no big patterns in the
Pacific that are rainmakers," he said. "There's no El Nino galloping
over the horizon to save us here."
