Tropical-Like Showers & T-Storms Likely Again Today

A moist, tropical airmass is in place across much of central and east Texas again this morning. This instability, combined with energy from a middle and upper-level low pressure system over the Arklatex region will result in pretty solid coverage of showers and thunderstorms. The most likely time for development is after 11am and will continue through late afternoon/early evening. The most likely area for more widespread coverage is in an area from Austin northward through the Dallas/Ft. Worth Metroplex, and on East toward the Arkansas/Louisiana borders. This activity is expected to diminish rapidly after 6pm.

Very heavy rainfall along the I-35 corridor.

Very heavy rainfall has developed along the I-35 corridor from San Antonio to Austin. Locally heavy rains of 1 to 2 inches per hour can be expected through at least 2pm across this area. Flooding of small creeks, streams and other low lying areas can be expected, as well as widespread street flooding.

Much Needed Rains on Tap for Central & South Texas

A slow moving cool front will combine with copious amounts of low level moisture, as well as several upper-level disturbances, to produce widespread rainfall today across central and south Texas. Some of the storms will produce locally heavy rainfall that may accumulate several inches in one location. Activity will continue to develop & increase through midday and become widespread this afternoon & evening.

Big, Severe Storms Pound Oklahoma

Severe storms continue to pound central through northeast Oklahoma this evening. A large, high precipitation (lots of rain and hail), supercell thunderstorm is currently tracking East/Southeast at 25 to 30 mph to the West of Oklahoma City. This storm is producing hail up to the size of baseballs and we continue to monitor the Southwest portion of the storm for tornado development. Radar and spotters on the ground continue to indicate occasional rotation and a lowering "wall cloud" with this very dangerous storm.

Severe Storms Develop Along Cold Front

UPDATE 6:35 PM: Severe storms have developed along the front. Individual storms are moving East at 30 mph, while the front/line is moving Southeast at 15 to 20 mph. Large hail of 1 to 1.5 inches has been the most common report so far, but we are watching the southwestern most storm as it is slowly developing signs of rotation. Severe thundestorm watches are in effect along and ahead of the front until 11pm this evening...

Severe Weather Season Ramping Up

The 2009 severe weather season is well underway, with yet another risk of significant severe storms and flooding in the central Plains and Midwest again today. As of the time of this writing, we are expecting severe storms to develop along a slow moving cold front from east-central and southeast Kansas into Oklahoma, and quickly become severe this evening. Large hail and damaging winds are the primary severe weather threats, however isolated tornadoes are also possible, particularly across western and central Oklahoma. We'll post an update later this evening and a full recap of the evenings events tomorrow...
