High risk of a major tornado outbreak today; 13 dead from Leap Day outbreak

A powerful spring storm system is gathering strength over Missouri this morning, and will track northeastward into Southern Michigan tonight. The atmosphere in the storm's warm sector, south of the the warm front and east of the cold front, is very unstable, thanks to a flow of warm, moist air from the Gulf of Mexico at the surface, and very cold, dry air aloft. A powerful jet stream with winds winds aloft blowing at 150 mph will interact with this unstable air, and the strong change of wind speed and direction with height (wind shear) associated with this jet will impart a strong twisting motion to updrafts that from in this afternoon's thunderstorms along the cold front. These are ideal conditions for tornado formation, and a large tornado outbreak with damaging long-track tornadoes is likely late this afternoon in the Ohio and Tennessee Valleys. NOAA's Storm Prediction Center has placed Central Kentucky, Northern Tennessee, and a small portion of Southern Indiana in their "High Risk" area for severe weather Friday afternoon and evening, and is warning of the possibility of long-track significant tornadoes. While the conditions are not as dangerous as those we saw in 2011 during the May 21 - 25 Joplin, Missouri and late April Southeast U.S. tornado outbreaks, the potential exists for a punishing tornado assault with many more strong and violent tornadoes than occurred during the Leap Day outbreak. A number of severe thunderstorms with damaging winds have already formed this morning along the storm's warm front, in Missouri, Indiana, and Illinois. Consult our Severe Weather Page and Interactive Tornado Page to follow the storms.


Figure 1. NOAA's Storm Prediction Center has placed Central Kentucky, Northern Tennessee, and a small portion of Southern Indiana in their "High Risk" area for severe weather Friday afternoon. This is highest level of alert.


Figure 2. NOAA's Storm Prediction Center is calling for a 30% chance of tornadoes today within 25 miles of each point in the pink shaded area. Within the hatched area, there is a 10% or greater probability of strong EF-2 and EF-3 tornadoes, or violent EF-4 and EF-5 tornadoes within 25 miles of a point.

Leap Day tornado outbreak death toll hits 13
The cleanup continues today from the round of deadly tornadoes that pounded the Midwest on Leap Day, killing thirteen people. The outbreak began on February 28, when nine confirmed tornadoes touched down. A pair of EF-2 tornadoes hit Buffalo, Missouri and Harveyville, Kansas, with each twister causing one death. Also on that day, a weak EF-0 tornado moved over open fields near Gandy, Nebraska--the first February tornado in Nebraska since record keeping began in 1950. The outbreak continued on Leap Day, February 29, with 27 more confirmed tornadoes. Hardest hit was Harrisburg, Illinois, where a violent EF-4 tornado with 180 mph killed six, injured approximately 100, and damaged 200 homes and 25 businesses. The tornado cut a path 26.5 miles long and 275 yards wide across the town, according to the NWS damage survey. The only EF-3 tornado of the outbreak hit Asherville, Missouri that day, killing one person. The other deadly tornadoes of the outbreak included an EF-2 tornado that killed one person in Cassville, MO; an EF-2 that killed two in Monterey, Tennessee, and an EF-1 that killed one person in Smithville, Tennessee. An EF-2 tornado also plowed through downtown Branson, Missouri on Leap Day, injuring 33 people. An NWS storm survey found the tornado was 400 yards wide and carved a path 22 miles long. Overall, damage from the two-day tornado outbreak will run in the hundreds of millions, and could add up to the first billion-dollar weather disaster of 2012 in the U.S. The 36 confirmed tornadoes from the outbreak make it the second largest February tornado outbreak since record keeping began in 1950. The biggest February tornado outbreak occurred on February 5 - 6, 2008, when 92 tornadoes touched down.


Figure 3. Damage at the Branson, Missouri Hilton after the Leap Day tornado. The tornado blew out or cracked windows in 219 of the hotel rooms in the 12-story/295 room Hilton Branson Convention Center, and extensively damaged three of Branson’s 50 plus theatres--Americana Theater, Branson Variety Theater and Dick Clarks’ American Bandstand Theater.

There's still a lot of 65 to 70dbz cells in Mississippi and Alabama.

Quoting KeyWestSun:

If you're trying to tell me these things are as intense as earlier, I'd have to disagree. Plus, new outlook downgraded to Moderate Risk.

Storms die out as nightfall nears...generally.
That's because that area wasn't expected to be as strong as Kentucky storms. In fact, Moderate Risk expended in that area. High Risk was never issued there.

With 78 reported tornadoes, today is now the largest tornado outbreak since April 27.

I think that we have been all warned to expect more Extreme Weather, everywhere.
I hope this is another anomaly. But I kind of doubt it, somehow.

Very tragic situation.

Whites and pinks slowly fading away with the dark of night looming. Still very severe storms but slowly weakening.

I don't think so. These storms will remain extremely dangerous and will be capable of producing violent tornadoes for the next several hours.

Possible large tornado moving just south of Charleston, WV.



Maybe not much population in that immediate area, but once it nears the river, the population density will increase substantially...

Everyone out there stay safe.
Sleeping in the basement can be a very good thing tonight if you are in the path of these storms. If you have kids you can pretend that you are camping out, or something like that.
A friend's basement will work, too, if you don't have one yourself.

These cells look so much like the cells we had in April of last year here in NC. Separated so they are able to do their own thing. Started forming just east of Durham so missed out on the whole thing. Thank goodness.

I remembered tracking the storms that day. The cells were in line, and then splits. So many bad tornadoes that day. I was spared from 2 EF-3 that day (tornadoes passed 10 miles to north and 5 miles to south). My grandparents were spared from Sanford tornado by A MILE as well. I visited Sanford to see them and damage to Lowe's was just crazy.
