A line of thunderstorms developed along and ahead of a cold front across extreme Northwest Louisiana and deep East Central Texas during the early evening hours of February 6th. This activity developed in a stable surface airmass but decreasing temperatures aloft resulted in strong lapse rates aloft which allowed for increasing lift along the frontal boundary.

The episode as NWS SHV wrote it up.
A line of thunderstorms developed along and ahead of a cold front across extreme Northwest Louisiana and deep East Central Texas during the early evening hours of February 6th. This activity developed in a stable surface airmass but decreasing temperatures aloft resulted in strong lapse rates aloft which allowed for increasing lift along the frontal boundary. As a result...the storms moved into North Central Louisiana but not before producing some isolated hail reports along with some wind damage.
