Tornado warnings in Oklahoma

Multiple tornado warnings have been issued for Oklahoma City and its suburbs this afternoon, and forecasters warn that tornadoes are possible after dark tonight in Kansas counties south of Wichita.

The storm threat will grow as more moisture pours into the Sunflower State, National Weather Service meteorologist Brad Ketcham said. The greatest tornado threat will likely be in Sumner, Harper and Cowley counties, he said.

That fits, considering the Storm Prediction Center of the National Oceanic and Atmospheric Administration has shifted the moderate risk’s northern boundary to the Kansas/Oklahoma border. The severe thunderstorm warning for Butler, Chase and Marion counties demonstrates that moisture and instability have established themselves in the region.

Walk around outside in the Wichita area, and you’ll feel a mix of cold and warmth in the atmosphere that reflects the clash of air masses typically associated with strong thunderstorms. While it doesn’t have that textbook sticky, unsettled sensation that has been prevalent on such major tornado outbreak days as April 26, 1991, or May 3, 1999, I’m not surprised at all that storms are firing today.

‘Major tornado outbreak’ expected today…

…..in the southern Plains, multiple sources tell me. The Storm Prediction Center has placed most of Arkansas and portions of Oklahoma, Texas and Louisiana under a moderate risk for severe weather today. Several surrounding states, including the eastern half of Kansas – and the Wichita metropolitan area – face a slight risk of severe weather.

“This will be the first big severe weather episode of 2009,” Greg Carbin, warning coordination meteorologist for the SPC, told me. “Stay tuned.”

The Storm Prediction Center’s warning states, “A significant severe weather outbreak – including supercells with strong tornadoes – is expected this afternoon into tonight for eastern Oklahoma, northeast Texas into western/central Arkansas and northwestern Louisiana.”

The threat for Wichita isn’t as substantial, though local forecasters are nonetheless urging residents to be prepared. A hazardous weather outlook issued by the Natoinal Weather Service cautions that large hail, damaging winds and tornadoes are possible tonight in the Wichita area.

KSNW meteorologist Mark Bogner is calling today “the first major tornado outbreak of 2009.”
