The Fort Worth radar is showing a clear tornado debris signature in the long lived supercell in southwestern Johnson County west southwest of Rio Vista, heading in the general direction of that town. It will pass near Covington and near Grandview on I-35, just north of the split south of Dallas/Fort Worth.

The Andover Tornado of 1991

| 4:10 pm April 26, 2015

On this day 24 years ago, an F5 tornado devastated the community of Andover, Kansas, in a violent tornado outbreak over the plains of Kansas, Oklahoma and Nebraska. On April 26, 1991, a total of 55 tornadoes developed, 30 of which were rated an F2 or greater. At one point during the storm, three separate F4 or F5 tornadoes – Andover, Red Rock, and Arkansas City – were simultaneously on the ground. 21 people died as a direct result of the April 26, 1991 severe weather – 17 from one storm alone.

While the April 26, 1991 storm is most known for the destruction of the Andover community, this same twister also hit parts of Wichita, McConnell Air Force Base and other parts of South Central Kansas. The following devastating tornadoes occurred primarily during the afternoon and evening hours across northern Oklahoma and southern Kansas.

The Andover tornado initially exhibited multiple vortices, producing F3 damage. As it veered north, it bore down on Haysville, Kansas, just south of Wichita. It passed through the southeastern part of Wichita, passing just a mile south of the South Wichita interchange on the Kansas Turnpike. McConnell Air Force Base was next on the tornado’s agenda. The twister crossed the Base’s runways and missed a billion dollar line of B-1B bombers by less than one thousand feet. The southern part of the Base received F2-F3 damage. The Officer’s Club, Base Hospital and base housing were heavily damaged. But the tornado was growing in size and intensity.

A subdivision near the Sedgwick County/Butler County line was nearly completely leveled as the tornado grew to its highest intensity. As the tornado turned into an F5 monster, it set its sights on the Golden Spur Mobile Home Park in Andover about 6:45 p.m. Warnings mentioning Andover specifically were issued seven minutes before the tornado arrived; however, the sirens in Andover were not working. A police cruiser drove through the park sounding its sirens as a warning. Many of the residents had heard about the approaching tornado from local television coverage and headed to the park’s storm shelter. Others said they would not take shelter until the funnel was visible. Fortunately, the tornado was slow moving and highly visible, and many made it to shelter in time. Over 200 people were huddled in the shelter when the twister struck, annihilating 233 of the 241 homes. The tornado obliterated the mobile home community, killing thirteen people. Twisted frames were the only remains of many of the mobile homes.

The tornado thankfully moved into more rural territory northeast of Andover, crossing the Kansas Turnpike. Near El Dorado, the tornado literally bounced a huge oil tank over a half mile. When the tornado finally lifted about five miles north of El Dorado, it had been on the ground for forty five miles. A total of seventeen people in the Andover community lost their lives. Right after the Andover tornado lifted, the same storm produced another tornado that was captured on news video as it passed near on overpass on the Kansas Turnpike, which enforced the false belief that overpasses could provide safe shelter during tornadoes.

Is the Severe Weather Over for Central Alabama? Yes!

| 6:35 pm April 25, 2015

2015-04-25_18-52-08

Yes!

The severe thunderstorm watch for East Central Alabama has been canceled as the last storms have moved into Georgia and no addiitonal storms are expected overnight.

We had one shot at severe weather this afternoon and evening across Central Alabama and it is done.

The ingredients that were in place over the area are diminishing now. The speed shear is diminishing as the upper level wind max departs to the north. Instabilities are slowly coming down as clouds cover the area. The convection near the Gulf Coast has effectively cut off additional moisture inflow into the area and drier air is moving in.

There should not be any more convection initiating tonight. There could be a few light showers as the cold front approaches from the north during the pre-dawn hours, but there won’t be any thunder.

A passing disturbance and conditionally unstable air caused by cold air aloft tomorrow could trigger a few light afternoon showers as well, but they will be a nuisance at worst, not heavy and not lasting very long at all.

@auburnwde reported destruction of a barn in northern Coosa County caused by strong winds in the severe thunderstorm at 5:18 pm, four miles west of Stewartville on County Road 35. The damage is impressive and could have been caused by a tornado or straight line winds, hard to tell until the Weather Service surveys the damage. There were definitely strong winds, over 65 mph near the surface, shown on doplar radar.
