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.

Portlight disaster relief charity responds to the Harrisburg, Illinois tornado
Portlight has a seasoned veteran from last year's tornado recovery efforts in Harrisburg, IL, and is looking for more people to volunteer their time. They are teaming with another disaster recovery charity, Team Rubicon, in the effort. As usual, they will be focusing efforts on the unserved, under served and forgotten. Please visit the Portlight Disaster Relief blog to learn more. Donations are always welcome!

Quoting Neapolitan:
generally speaking, if there's a lull of six hours or more, it's considered a separate outbreak. It should, however, be considered part of a single outbreak sequence.


Which seems to be a concept that some have a tough time with. Many many articles on wikipedia report outbreak sequences as outbreaks, then compare them as if they are similar. One that bugs me in particular is the comparison of the 1974 super outbreak to the one of last year, even though wikipedia uses like 3-4 days for last year's "outbreak."

You guys are doing a good job today. I will say that the warning we got below although it said Hamilton County in the text, did not list anywhere in Hamilton county as being in the warning area. Neither did the geometry show the warning to be listed for us.

I know the Blue Cross in Downtown Chattanooga had everyone get to the basements as soon as this warning went out.

The next warning at 12:16 that went out did seem to include Chatt and the surrounding areas in the 'affected areas' and definitely was appropriate. We (at Covenant Transport) took cover after that warning. It may be something to check into....tomorrow...

Probably something you'll have to inquire with the MRX NWS office about.

Although I know a decent amount about severe weather and radar detection and have been through warning training, I actually work at a regional river forecast center. We cover a good chunk of the south central US, mostly tributaries going into the Lower Miss River. That's why I know the terrain up in those parts pretty well, as it is important to runoff/flooding processes :)

Quoting ScottLincoln:


That area is in our forecast responsibility area, so I'm aware. Terrain can do weird things to circulations like that. Sometimes it doesn't do anything, but sometimes terrain seems to help trigger circulations to become tighter, other times there might be disruptions. But I think the bigger factor is the actual mesoscale conditions becoming less favorable for those storms to be supercellular.

Tight circulation has now developed just northwest of the Evansville, IN, metro. Getting good resolution of the circulation from the NEXRAD nearby. Tight hook, 120-130kts of shear ~800ft. That amount of shear at that elevation is very likely a tornado already on the ground.

The Darmstadt, Inglefield, and Highland areas of north metro Evansville are at highest danger from this potential tornado in the next 15 minutes.

Tornado Safety Tips
Look & Listen for
...large hail, heavy rain, strong winds, frequent intense lightning ...bulge with a rotary motion at the base of the thunderstorm cloud ...loud roar like the sound of a jet or train.
Seek Safe Shelter

A basement is best. Otherwise choose ground-floor center rooms surrounded by other rooms. Never choose upstairs locations because tornadic wind speeds increase with height above the ground.

Choose rooms on the north and east sides of your shelter if no interior rooms are available. Stay near the innermost walls. Avoid rooms on the south and west, because tornados usually travel from southwest to northeast.

Choose a small closet or bathroom, because small rooms are less susceptible to collapse. Take shelter within the bathtub if there are no glass tub enclosures or large mirrors nearby.
How to Protect Yourself and Your Family

Stay calm.
Seek shelter IMMEDIATELY!
Keep a portable TV/radio and flashlight in your shelter.
Wear shoes to protect your feet from broken glass and other debris left by the storm.
Protect head and chest- crouch, face to floor, hands behind head.
Cover yourself with blankets, pillows or coats.
Hide under sturdy furniture.
Avoid candles, gas lanterns and oil lamps.
In schools and offices: seek designated shelter in interior rooms or hallway's on ground floor, or lowest floor possible. Avoid auditoriums and gymnasiums.
In shopping malls, seek the smaller interior shops on the ground floor.
In shopping centers, avoid large open rooms as well as the south and west walls.
Evacuate mobile homes and vehicles! Seek shelter in substantial structure, ditch or culvert.
Staying Safe in a Tornado

Ohio averages 16 tornadoes per year. Are you prepared?

Staying safe in a tornado's path:
As the skies darkened and the winds began to gather speed, the people of Xenia, Ohio had no idea that just minutes later, their town would be devastated by one of the worst tornadoes in Ohio history. That was 1974. And 25 years later, the people of the small Ohio town remember vividly the act of Mother Nature that took 32 lives.
Since then, towns throughout the U.S. have been hit by deadly tornadoes.

What is a tornado?
A tornado is the most violent atmospheric storm. A tornado is defined as a violently rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of 250 mph or more. Damage paths can be in excess of one mile wide and 50 miles long. Once a tornado in Broken Bow, Oklahoma, carried a motel sign 30 miles and dropped it in Arkansas.
According to the National Weather Service, although tornadoes occur in many parts of the world, these destructive forces of nature are found most frequently in the United States east of the Rocky Mountains during the spring and summer months.
In an average year, 800 tornadoes are reported nationwide, resulting in 80 deaths and more than 1,500 injuries.

Safe places you can go:
According to the National Oceanic and Atmospheric Administration, basements and interior rooms are the safest places to be during a tornado.
A good rule of thumb is to put as many walls and floors as possible between you and the tornado. Once you find a safe place, take shelter underneath a sturdy bench, table, or the stairwell. Crouch down and place your head between your knees, using your arms to cover your head.
On the other hand, the least safe place to be is in a car. If you are in a car, abandon it immediately and find a ditch to lie in. Most tornado deaths occur in cars. And never try to outrun a tornado; it may be moving faster than you think!
If you do find yourself in a tornado's path, go to the basement. If there is no basement, go to an interior room on the lowest floor, such as a bathroom or closet. If possible, cover yourself with a blanket or mattress to protect yourself from flying debris.
Remember to stay away from exterior walls or glass-enclosed places and windows.

A warning versus a watch:
A tornado watch is issued when conditions are favorable for producing a tornado. When a tornado watch is issued, keep an eye on the weather and go over the tornado safety plan with your family. If weather conditions worsen, seek shelter.
A tornado warning is issued when a tornado has been spotted. In the case of a tornado warning, seek shelter immediately.

Tornado danger signs:
When a tornado is approaching, a dark, often greenish sky, a wall cloud and large hail may appear.
A loud roar similar to that of a freight train may be heard. An approaching cloud of debris can mark the location of a tornado even if a funnel is not visible.
Before a tornado hits, the wind may die down and the air may become very still. This is the calm before the storm.
Tornadoes generally occur near the trailing edge of a thunderstorm and it is not uncommon to see clear, sunlit skies behind a tornado.

Be prepared before the storm hits:
By the time a tornado is heading toward you, it is usually too late to make a plan. According to the Federal Emergency Management Agency, you should:
· Conduct tornado drills each tornado season.
· Designate an area in the home as a shelter, and practice having everyone in the family go there in response to a tornado threat.
· Ask an out-of-state relative or friend to serve as the "family contact." After a disaster, it's often easier to call long distance. Make sure everyone in the family knows the name, address, and phone number of the contact person. This will help should the family be separated during the storm.

Preparing a tornado safety kit:
The American Red Cross suggests that you assemble a "disaster supplies kit" that you keep in your shelter area. The kit should contain:

1. A first aid kit with essential medication in addition to the usual items
2. A battery powered radio, flashlight, and extra batteries
3. Canned and other non-perishable foods and a hand-operated can opener
4. Bottled water
5. Candles and matches
6. Sturdy shoes and work gloves
7. Cash and credit cards
8. Written instructions on how to turn off your homes utilities

After a tornado:
1. Help injured or trapped people.
2. Give first aid when appropriate.
3. Don't try to move the seriously injured unless they are in immediate danger of further injury.
4. Call for help.
5. Turn on a radio or television to get the latest emergency information.
6. Stay out of damaged buildings.
7. Return home only when authorities say it is safe.
8. Use the telephone only for emergency calls.
9. Clean up spilled medicines, bleaches, or gasoline or other flammable liquids immediately. Leave the building if you smell gas or chemical fumes.
10. Take pictures of the damage, both to the house and its contents, for insurance purposes.
11. Remember to help your neighbors who may require special assistance--infants, the elderly, and people with disabilities.

Quoting zawxdsk:


The mountains also disrupt the inflow. If you're looking for elevations of them, they are about 1400ft above the valley floors - but they are straight cliffs.


That area is in our forecast responsibility area, so I'm aware. Terrain can do weird things to circulations like that. Sometimes it doesn't do anything, but sometimes terrain seems to help trigger circulations to become tighter, other times there might be disruptions. But I think the bigger factor is the actual mesoscale conditions becoming less favorable for those storms to be supercellular.
