Tornadoes rip Oklahoma, killing 5; oil spill headed towards Texas
Oklahoma residents are picking up the pieces and surveying the damage after a devastating tornado outbreak that left at least five people dead, dozens injured, and hundreds of millions in damage. Our severe weather expert, Dr. Rob Carver, has some amazing images and videos of the tornadoes in his blog. One solace Oklahomans can take in the disaster is that the data taken by scientists during the tornado outbreak may help forecasters issue better tornado warnings in the future. Usually, a proven way to reduce the incidence of dangerous weather phenomena is to schedule a multi-million dollar field experiment to study the phenomena. This is what happened last year, when the largest tornado field study ever conducted, Vortex2, kicked off. The $10 million study deployed an armada of over 100 storm chasing vehicles across the Great Plains, and were disappointed by one of the quietest tornado seasons in history. But it's pretty tough to have two consecutive record quiet tornado seasons in a row, so the Vortex2 program scheduled the study to run this year as well, beginning on May 1. Unfortunately for the residents of Oklahoma, the atmosphere unleashed one of its classic tornado outbreaks yesterday, in a region NOAA's Storm Prediction Center had outlined at "High Risk" for severe weather. The Vortex2 team was ideally positioned to intercept the tornadoes, according to the team of University of Michigan students that has been writing our featured Vortex2 blog, and I am told that they successfully collected what is probably the best data set even taken of a tornado outbreak. This was no mean feat, since yesterday's storms were moving 60 mph, making it extremely difficult to position the chase vehicles to capture the storm's secrets.

Oil spill may approach Texas early next week
The Deepwater Horizon oil spill has pushed steadily westward along the Louisiana coast, and is expected to reach central Louisiana near Atchafalaya Bay by Thursday, according to the latest trajectory forecasts from NOAA. Winds over the Gulf of Mexico this week will blow from the southeast at 15 - 20 knots, threatening to bring oil to large portions of the Louisiana coast. The Mississippi and Alabama coasts will also be at risk, but the risk to the Florida Panhandle is lower. It appears quite unlikely that oil will get into the Loop Current anytime over the next two weeks, and spread to the Florida Keys and beyond. However, the strong southeast winds are expected to shift more easterly late this week, and drive a westward-moving ocean surface current with a speed of 1 - 2 mph along the west coast of Louisiana late this week (Figure 2). This current may be capable of transporting oil all the way to the Louisiana/Texas border by Monday. However, the concentrations of oil in the water will be much less than what is present close to the blowout, and it is unclear what the potential danger is for the western Louisiana and eastern Texas coasts. The greatest danger is to the Eastern Louisiana coast.

Note that a strong ocean current near 1 m/s (about 2 mph) is forecast to set up along the Western Louisiana coast, which could take oil close to the Texas offshore waters by Monday.

I'm in Tucson for the American Meteorological Society's 29th Conference on Hurricanes and Tropical Meteorology. I'll be posting Wednesday morning on some of the latest findings presented at the conference, or discussing yesterday's tornado outbreak.

It's taken a while to cool down this autumn in the southeast, so today's frosty morning must have come as a shock to many.
Much of Victoria, Tasmania, South Australia and southern NSW were five 10 degrees colder than the previous morning as temperatures plummeted to near freezing.
Residents of Narrandera in southern NSW had to cope with the biggest change, a drop of 12 degrees from 13 to just 1 degree this morning.
Just over the Victorian border Rutherglen had its coldest morning since last July with a minimum of minus three degrees.
Quite a few centres over a large area had their coldest May morning in four years, including the Alps where snow fell to about 1000 metres above sea level.
Others which had their coldest May morning in four years were:
- Horsham (Victoria) -2 (28.4F)
- Longerenong (Vic), -2 (28.4F)
- Hopetoun (Vic), -3 (26.6F)
- Young (NSW), -4 (24.8F)
- Nurioootpa (SA), 1 (33.8F)
- Kadina (SA), 3 (37.4F)
This cold snap has been brought about by the strongest cold front of the season bulldozing its way across the region. The front is now crossing the Tasman Sea.
The next few mornings will be similarly cold, even colder for some places as skies clear and winds ease.

Definitely possible to see some tropical activity in late May. The Farmers Almanac is predicting the possibility of a storm around the 23rd to impact the SE. It said MAYBE tropical
Good evening. The ENSO Wrap-Up update came out this morning and proclaimed El Nino dead.

It wasn't a dust storm. It was smoke from a back burning operation in the Blue Mountains
You don't usually get subtropical storms in the Caribbean in May. The system on the GFS is of fully tropical origin. The front coming down from the north is a separate entity and would only serve to pull the system north or northeastward, as is typical with early-season tropical cyclones.
You always seem to beat me to it, but it's cool. Yes El Nino is dead.
