Severe Weather Survey

| 4:25 pm February 26, 2015

WeatherBrains Panelist Rick Smith, who is the outstanding Warnings Coordination Meteorologist at the National Weather Service in Norman, Oklahoma, has been working with a couple of very bright OU senior met students on their Capstone project, which involves learning how people process and respond to severe weather information.

They developed a quick survey and are collecting responses for the next week or so.

Please take a moment to participate in the survey.

And Now… A Tornado Watch!

The low pressure system in the Gulf of Mexico (1004 mb) is pushing a warm front into the Florida Panhandle. The SPC has issued a Tornado Watch for the Florida Big Bend area and extreme southern Georgia, including Panama City, Tallahassee and Valdosta. The tornado watch is shown in purple on the graphic.

Sorta reminiscent of the March 1993 Superstorm, just 30 millibars weaker!

Strong radar indications of damaging winds in the bow echo crossing the Alabama border into Sumter County have prompted a severe thunderstorm warning for Sumter and for downstream Greene County tonight.

The storm is just east of Geiger and will move east northeast toward Gainesville, Union, Clinton and Knoxville. There have been several reports of damaging winds across Mississippi from this storm, mainly downed trees.

The storms will move into southern Tuscaloosa County, mainly remaining south of I-59, but should gradually weaken as it outruns its instability.

Strong Storms Will Make it Into Alabama

| 6:13 pm February 1, 2015

2015-02-01_18-11-30

As expected, storms have intensified late this afternoon over Central and southwestern Mississippi ahead of a strong cold front, triggering severe thunderstorm warnings.

At 5:22 p.m., winds gusted to 68 mph at Jackson’s Hawkins Field. Winds have gusted to 48 mph at Jackson International Airport. Trees have been reported downed in Edwards and Raymond as well.

Half inch hail was reported at Fairhaven in Madison County north of Jackson.

A tree was reported down in Vicksburg at 4:35 p.m.

There is not much instability (less than 500 j/kg) and low level lapse rates are weak, but there is quite a bit of wind shear and the updrafts that the atmosphere is managing to send up are bringing it to the surface in spots.

There is a strong indication of damaging winds over Leake County as a bowing structure moves toward Neshoba County and Philadelphia. There is probably some small hail in that storm as well.

The storms will weaken as they move into Alabama, but could remain strong into parts of Lamar, Fayette, Tuscaloosa, Greene, Hale, Bibb and Sumter Counties and points south, generally south of a line from Fayette to Brent to Selma. We probably will see a couple of warnings in this area.

The storms will reach West Alabama on the following time schedule:
…Pickens County before 7 p.m.
…Sumter County before 7:30 p.m.

They will reach Tuscaloosa by 9 p.m. and Birmingham by 10 p.m.

North and North Central Alabama groundhogs may not see their shadow in the morning, but they might be so terrified by snow flurries that they scurry back into their comfy dens. Snow flurries will be possible before 6 a.m. in places north of US-82 and west of I-65 and before 9 a.m. in places east of I-65 and north of I-20.

Storms Weakening, Still Packing a Punch

Our line of strong storms is weakening now. It extends from Pell City to Harpersville to Columbiana.

Winds gusted to 31 mph at the Shelby County Airport in Calera.

More severe thunderstorm warnings will not be issued unless the storms re-intensify.
