Enhanced Risk of Severe Weather Today 1/21/2016

Our own Scott Peake is chasing today in Louisiana -stay tuned for pictures & video!
As of writing this, there is already a tornado-warned storm near Farrsville, TX, and storms by Lake Charles, LA are already showing signs of rotation.


Severe weather setups are actually quite common in the Southeastern United States during the winter months. Currently, there is a low centered over the Texas/Louisiana border with storms ongoing in its center. There is a warm front in southern Louisiana, and high dew points (mid to upper 60 degree dews) in the warm sector of this low.

Typically in the Southeast, we get severe weather in ‘high shear, low CAPE’ environments. Today however, there is also high CAPE (Convective Available Potential Energy) or instability. Current surface-based CAPE analysis is showing values of 2500J/KG of CAPE in southern Louisiana and extreme SE Texas.

These higher CAPE values increase the likelihood for large hail. The 2500 J/KG CAPE combined with high shear and good storm relative helicity are key ingredients for severe weather. Strong to severe supercells are already on-going and tornadoes are likely.


Currently there is a Tornado Watch until 7:00pm CDT – in this Tornado Watch
“A FEW TORNADOES LIKELY
SCATTERED LARGE HAIL AND ISOLATED VERY LARGE HAIL EVENTS TO 2 INCHES IN DIAMETER POSSIBLE
SCATTERED DAMAGING WIND GUSTS TO 70 MPH POSSIBLE”
If you live in the the risk of severe weather today, please stay tuned to local TV/News and NOAA Weather Radio / phone alerts for tornado warnings & seek shelter if you happen to be in one!
