I may be taking a trip to Las Vegas this weekend.. and guess what's in the forecast?
SNOW!
i've been to Vegas 5 times, and 3 of them its been pouring rain. Now if the computer models are correct i will have snow as well. The bad news is the drive out will NOT be pretty.
oh man i cant believe someone brought up the tunnels again. and now cyclonebuster has taken to cackling like a mad scientist!
and according to theory any probe sent into a black hole would be crushed long before it entered.. still definitely a worthwhile mission if we could pull it off but once its beyond the 'event horizon' radio waves, etc, can't escape the black hole anyway, so even if the probe survived, we'd never know
Inyo, everything we know about black holes is theory!!!!
Who knows what will happen if the probe was sent????
I think it would be a HUGE scientific experiment even if the hole swallows the probe. Think of the data that would come from this. Also you never know..... there just "might"
be another side or dimension inside a black hole!!!!!!!!!
My husband cashed in on the Miller Lite Karina specials... so much so, I haven't seen him touch it since.
Waiting for a front here in LA but looks like it stalled out over Ventura County.. we may not get much more than drizzle out of this one.
NASA satellites feel budget crunch
Budget cuts and poor management may be jeopardizing the future of our eyes in orbit -- America's fleet of environmental satellites, vital tools for forecasting hurricanes, protecting water supplies and predicting global warming.
The dryness is moving north. The Drought Monitor lists abnormal dryness or moderate to severe drought for all of Kansas; most of Nebraska, Iowa, Missouri and Illinois; and much of South Dakota and eastern Colorado. The monitor also reports soil moisture in Nebraska is so low that farmers have begun irrigating months ahead of normal. Most of the Texas Panhandle winter wheat crop is in peril.
Texas and Oklahoma suffered fierce winter grassfires that scorched thousands of acres, destroyed about 500 homes and killed at least five people. More fires broke out last week.
The Arizona Game and Fish Department has begun hauling water to wildlife herds as winter has failed to replenish remote watering holes. With no moisture to keep the dust down, air quality in Phoenix has worsened to unprecedented winter levels: 24 pollution alerts since Nov. 1. One or two is normal.

Dr Masters~ I notice you all offer stock as a benefit. I assume that's WU stock. If so what symbol does it trade under?
wunderground.com is privately held, so there is no public stock available.

who knows...mother nature doesnt want to be predicted it seems
The current patterns of SST annomolys, percipitation & atmosphereic winds are consistant with La Nina.
Most model forecasts predict weak La Nina to persist April-June 2006.
Current conditions & latest forecasts support the continuation of La Nina conditions during the next 3 months.
Vampire Vortices Suck Each Other's Energy
By Kimberly Krieger
ScienceNOW Daily News
2 March 2006
From the humble swirling of bathwater down the drain to the violent storm on Jupiter, vortices thrive by sucking the energy from smaller ones, report researchers. Such vortex cannibalism contradicts the common view that vortices grow via benevolent mergers. But it confirms a famous hypothesis and could help explain how energy moves through the atmosphere and the oceans.
In the 1970s, Robert Kraichnan proved mathematically that, in two-dimensional situations, energy should flow from smaller vortices to larger ones. But just because the math said so didn't mean anyone knew how it occurred. (Indeed, in three dimensions, energy flows from larger to smaller vortices.) The 2-D conjecture was considered extremely important because lots of weather is essentially two-dimensional; the enormous width and breadth of a hurricane makes its thickness negligible, for example. Because the 2-D case is so important to weather prediction, researchers have puzzled for 30 years over how energy actually flows between vortices in two-dimensions.
In the 3 March issue of Physical Review Letters, Gregory Eyink, a physicist at Johns Hopkins University in Baltimore, Maryland, and colleagues report that Kraichnan had it right. The group set up a pool of salt water about 1 meter square, laid it on a bed of magnets, and ran an electrical current through the water horizontally. When the magnetic field crossed the electrical field, the disturbance gave birth to hundreds of tiny vortices in the salt water. Then larger vortices took over.
The team took a step beyond Kraichnan's paper and proposed an idea of what's going on. A computer simulation showed that the larger vortices were stretching the smaller ones. Imagine a small vortex as a bunch of concentric circles. As it stretches, the path of a water molecule looping around one circle would stretch out, and the molecule would slow down, indicating that the small vortex is losing energy. This lost energy, the researchers found, is flowing to the larger vortex nearby. Energy transfer in the atmosphere should work the same way: not via mergers but rather through hostile takeovers, they conclude.
"This paper gives a very novel and plausible mechanism," for the energy flow between vortices in two dimensions, says Philip Marcus, a computational physicist at the University of California, Berkeley. Having that mechanism cleared up should be useful for improving weather models, he says.
I would not be at all suprised to see a pre-season storm.
In theory, the vortices approach would work with any intense low pressure system, wouldn't it?
I know La Nina correlates with drought in much of the southern United States. Also... i notice that the Nino 1 +2 is still rather warm... but i did read somewhere that its not unusual for that to happen in La Nina
