Dangerous tornado outbreak expected Saturday; Gulf of Mexico SSTs warmest on record

A dangerous tornado outbreak is expected on Saturday over the Plains, says NOAA's Storm Prediction Center (SPC). Warm, moist air flowing northwards from a Gulf of Mexico that has record-warm waters will collide with cold air funneling down from Canada, creating a highly unstable air mass capable of creating strong thunderstorm updrafts. An impressive upper-level low, accompanied by a jet stream with 105 - 125 mph winds at middle levels of the atmosphere, will create plenty of wind shear, giving the air the spin it needs to form tornadoes. SPC has has issued their highest level of alert, a "High Risk," for much of Oklahoma, Kansas, and Nebraska for Saturday. Included in the "High Risk" area are the cities of Wichita, Oklahoma City, and Lincoln. This is the second time SPC has issued a "High Risk" forecast this year; the first "High Risk" forecast came for the March 2 tornado outbreak, which killed 41 people and did $1.5 - $2 billion in damage. It is very unusual for SPC to issue a "High Risk" forecast more than a day in advance of a suspected tornado outbreak; according to Wikipedia, today's "High Risk" forecast is only the second time SPC has ever done this. The other instance was for the April 6 - 8, 2006 tornado outbreak focused over Tennessee, which generated 73 tornadoes that killed 13 and did $1.5 billion in damage. People living in the threatened area need to pay close attention on Saturday to this dangerous severe weather situation.

Gulf of Mexico water temperatures the warmest on record
Temperatures in the states bordering the Gulf of Mexico were the 3rd - 7th warmest on record during the first three months of 2012, according to NOAA's National Climatic Data Center. This allowed Sea Surface Temperatures (SSTs) in the Gulf of Mexico (25 - 30°N, 85 - 90°W) to climb to 1.4°C (2.5°F) above average during March 2012, according to a wunderground analysis of the Hadley Centre SST data set. This is the warmest March value on record for the Gulf of Mexico, going back over a century of record keeping. During the first two weeks of April, Gulf of Mexico waters remained about 1.5°C above average, putting April on pace to have the warmest April water temperatures on record. Only one year in the past century has had April water temperatures in the Gulf of Mexico more than 1.1°C above average; that year was 2002 (1.4°C above average.) All that record-warm water is capable of putting record amounts of water vapor into the air, since evaporation increases when water is warmer. Because moist air is less dense than dry air, this warm, moist air flowing northwards from the Gulf of Mexico into the developing storm system over the Plains will be highly unstable once it encounters cold, dry air aloft. The record-warm waters of the Gulf of Mexico are a key reason for the high risk of severe weather over the Plains this weekend.

April Storms (llpj04)
this storm greeted me as I came out of the grocery store, chased me home and got to my driveway the same time I did.

Last night we had a pretty spectacular lightning storm. I put the camera on the tripod in time-lapse mode and laid on my back on the hillside above the pond taking in an amazing show. When it got more exciting than I was comfortable with, I ran for the house.

May be hard to get good damage estimates since thankfully it didn't go over many structures.

Quoting RTSplayer:

Well, we saw it live on the chaser's live stream.

Horizontal vortices and a few attempts to put down vertical satellite vortices.

It was easily EF3 and maybe EF4 or 5...
Very violent and very debris filled too.
Good thing was it wasn't hitting much at the time.

It was in very rural areas. It could easily get rated EF1-2. Maybe a different story if it had hit a town. We'll know in the coming days.

Looks like the supercell near Salina is going through a lull right now. If it can just keep this up for another 10 minutes or so without recycling a new RFD, Salina will likely live to see another day.
Probably will get a good bit of hail nonetheless, but yes they may luck out! Perfect time to end a cycle.

...THUNDERSTORMS WILL PRODUCE BRIEF AND INTENSE HEAVY RAINFALL...

IN ADDITION TO THE SEVERE WEATHER THREAT THIS EVENING...THE
THUNDERSTORMS HAVE A HISTORY OF PRODUCING BRIEF...AND INTENSE...HEAVY
RAINFALL. IN THE MOST EXTREME CASES...TWO TO TWO AND HALF INCHES
OF RAIN HAS FALLEN IN LESS THAN ONE HOUR.

THROUGH THE REMAINDER OF THE EVENING...THE THUNDERSTORMS WILL BE
CAPABLE OF PRODUCE ADDITIONAL INTENSE AND BRIEF HEAVY RAIN.

THE HEAVY RAIN WILL LIKELY PRODUCE LOCAL URBAN AND SMALL STREAM
FLOODING. THE URBAN FLOODING WILL CAUSE LOCAL TRAVEL PROBLEMS.

IF THE STORMS TEND TO TRAIN OVER THE SAME AREA...FLASH FLOODING
WILL BE POSSIBLE AND WARNINGS WILL NEED TO BE ISSUED. THIS IS
POSSIBLE...BUT NOT LIKELY.

NEVER DRIVE TO FLOODED ROADS.

Yeah, reports is saying it's a funnel now. Also, the velocity radar on NWS Wichita is showing the rotation breaking up. Recycling is my guess.

CBS Newstream says tornado now 7 miles south of Brookville, headed NE towards Salina. However, it just added that it appears to have lifted. Could be encouraging news, maybe it's dissipating.

Though if I was in Salina right now I obviously wouldn't be gambling on it.

Honestly, I haven't been that impressed thus far from this outbreak (which is a very good thing). Seems like most of the tornado reports were very brief touchdowns. Now that doesn't mean it can't get worse, but were are approaching the traditional diurnal peak for tornado formation.

Couple dozen miles usually.

though once in a while you get one goes a lot more than that, like last year's Tuscaloosa cell, or a few others, the so-called "tri-state" tornado, etc.
Tuscaloosa cell was dropping and lifting up tornadoes for about couple of hundred miles from Mississippi to North Carolina. Tri-State was about 200 miles from Missouri to Indiana, but unlike Tuscaloosa cell, that was a single tornado (although it's still debated).

My folks are terrified of these things so for Mother's day Mom is getting one of those NOAA radio thingy's. Wonder if I can get one directly from the NOAA website.


Coming out of my usual lurking status to comment on buying a weather radio.

I called my local NWS office to ask which weather radio they recommended for the rural North Dakota area we lived in at the time. They suggested the Midland WR-300 (it's available at Amazon). We've since moved to the Bismarck, ND area and it's still working well.

One feature that I wouldn't do without, but didn't think about before buying, is battery back up. This radio has it. When we loose power from a storm, or take shelter, we unplug it and take it with us to keep getting updates.
