Trio of storm systems could have devastating impact on U.S.
Knight Ridder Newspapers
WASHINGTON - Moisture-laden storms from the north, west and south are likely to converge on much of America over the next several days in what could be a once-in-a-generation onslaught, meteorologists forecast Tuesday.
If the gloomy computer models at the U.S. Climate Prediction Center are right, we'll see this terrible trio:
All three are likely to meet somewhere in the nation's midsection and cause even more problems, sparing only areas east of the Appalachian Mountains.
"You're talking a two- or three-times-a-century type of thing," said prediction center senior meteorologist James Wagner, who's been forecasting storms since 1965. "It's a pattern that has a little bit of everything."
While the predicted onslaught is nothing compared with the tsunami that ravaged South Asia last week, the combo storms could damage property and cause a few deaths.
The exact time and place of the predicted one-two-three punch changes slightly with every new forecast. But in its weekly "hazards assessment," the National Weather Service alerted meteorologists and disaster specialists Tuesday that flooding and frigid weather could start as early as Friday and stretch into early next week, if not longer.
"It's a situation that looks pretty potent," Ed O'Lenic, the Climate Prediction Center's operations chief, told Knight Ridder. "A large part of North America looks like it's going to be affected."
Kelly Redmond, the deputy director of the Western Regional Climate Center at the Desert Research Institute in Reno, Nev., where an unusual 18 inches of snow is on the ground already, said the expected heavy Western rains could cause avalanches. Since Oct. 1, Southern California and western Arizona have had three to four times the normal precipitation for the area.
"Somebody is in for something pretty darn interesting," Redmond said.
The last time a similar situation seemed to be brewing - especially in the West - was in January 1950, O'Lenic said. That month, 21 inches of snow hit Seattle, killing 13 people in an extended freeze, and Sunnyvale, Calif., got an unusual tornado.
The same scenario played out in 1937, when there was record flooding in the Ohio River Valley, said Wagner, of the prediction center.
Meteorologists caution that their predictions are only as good as their computer models. And forecasts get less accurate the farther into the future they attempt to predict.
"The models tend to overdo the formation of these really exciting weather formations for us," said Mike Wallace, a University of Washington atmospheric scientist.
Yet the more Wallace studied the models the more he became convinced that something wicked was coming this way.
"It all fits together nicely," Wallace said. "There's going to be weather in the headlines this weekend, that's for sure."
Wagner was worried about the Ohio and Tennessee River valleys as the places where the three nasty storm systems could meet, probably with snow, thunderstorms, severe ice storms and flooding. Some of those areas already are flooded.
The converging storms are being steered by high-pressure ridges off Alaska and Florida and are part of a temporary change in world climate conditions, O'Lenic said.
Over equatorial Indonesia, east of where the tsunami hit, meteorologists have identified a weather-making phenomenon called the Madden-Julian Oscillation. It's producing extra-stormy weather to its east. Similar oscillations in the north Atlantic and north Pacific are changing global weather patterns. Add to the strange mix this year's mild El Nino - a warming of the equatorial Pacific - which is unusually far west, Redmond said.
There's also another, more playful explanation: The nation's weathermen are about to converge on Southern California, and they bring bad weather with them.
The American Meteorological Society will meet next week in usually tranquil San Diego, which should be hit with the predicted storms and accompanying flooding in time for the group's gathering.
In 1987,when the meteorologists met in San Antonio for their convention, the city had ice storms. In 1993, when they gathered in Anaheim, Calif., it rained for 4.5 out of five days and triggered mudslides. Atlanta got rare snow during the meteorologists' 1996 convention. And in 2003 in Long Beach, Calif., heavy rain greeted them.
Ron McPherson, the group's recently retired executive director, said: "It always rains on the weatherman's parade."

Don't worry, I'm sure the UN will muster up some relief aid for us.
(/sarcasm off)
LOL!
I said the other day we shouldn't be giving away all our money!
Here in Indiana we are expecting an ice storm. Flash Flood Warnings have been issued for much of the state.
So, if I am to understand these scientists correctly, they are saying that some nasty rainstorms will differ in significant ways from an earthquake and subsequent tsunamis?
I wonder why they didn't let us know if the rain storms will be different than a forest fire, which has exactly as much in common with rainstorms as earthquakes do.
Sounds like a routine winter weekend in coastal New England. A couple of feet of snow, some heavy rain as the Noreaster blows through and then 0 degree temps as the Canadian air is sucked down. Such is life.
I think we should "name" this warm, moist storm system from the Gulf. C'mon FReepers, I'm sure we can come up with something!
Northern New Mexico has had rain for a couple of days. Temperatures are much above normal (compared with Christmans's -5.)
Bring it on! In AZ we are in a huge 9 year drought, we need water lots and lots of it!
Indianapolis has had unusually warm weather since just before New Years Day. It will drop to the teens later this week when this cold front comes through, then back into the 50's early next week.
It's flooded here (SE Ohio Valley) since it's been raining for two days...and the really big storm hasn't hit yet.
Wonerful...
I sit on a ledge in a big forest overlooking a small creek, except now it's a raging river. This is big time to us. We will likely lose power and be unable to leave (or enter) our homes. These floods are new to us since they began in 1998, but not before. A 100-year flood has occurred four times this summer. Another, the fifth this year, one is occurring as I type. By tomorrow morning I will not be able to leave this place---except by heliocopter.
Hotlips.

How about "Wet Willie"?
Here in NC Iowa...
...WINTER STORM WARNING REMAINS IN EFFECT UNTIL 6 AM CST THURSDAY...
SNOW IS EXPECTED TO CONTINUE OVERNIGHT...THROUGH MUCH OF
WEDNESDAY...AND EVEN INTO WEDNESDAY NIGHT BEFORE DIMINISHING OR
ENDING EARLY THURSDAY MORNING. THIS PROLONGED PERIOD OF MAINLY
MODERATE SNOW...WHICH COULD ALSO BE HEAVY LATE WEDNESDAY AFTERNOON
AND EVENING...WILL PRODUCE TOTAL ACCUMULATIONS FROM 8 TO 12
INCHES...WITH A FEW SPOTS POSSIBLY EXCEEDING A FOOT. THE HEAVIEST
ACCUMULATIONS SHOULD BE ACROSS CENTRAL IOWA...WITH LESSER AMOUNTS FAR
NORTH AND SOUTH. NORTH TO NORTHEAST WINDS OF 10 TO 20 MPH WILL ALSO
PRODUCE BLOWING AND DRIFTING...ESPECIALLY ALONG EAST TO WEST ROADS IN
RURAL AREAS. SLICK SNOW COVERED ROADS AND REDUCED VISIBILITIES WILL
MAKE TRAVEL DIFFICULT FOR AN EXTENDED PERIOD.
Well since he'll get blamed for it anyway, we might as well name it George.
LOL!
