.AVIATION...

MVFR/VFR FLIGHT CATEGORIES STILL PERSIST ACROSS MOST ARKLATEX TERMINALS
THIS EVENING...BUT A LINE OF THUNDERSTORMS IS TRYING TO DEVELOP IN
TEXAS AS THE DRY LINE BEGIN TO ADVANCE EASTWARD AGAIN. IF THIS LINE
DOES FILL IN... ARKLATEX TERMINALS WILL LIKELY EXPERIENCE TEMPO
IFR CONDITIONS AS TSRA ACTIVITY MOVES THROUGH. I WENT AHEAD AND
ADDED SOME TEMPO TSRA INTO THE TEXAS TERMINALS...BUT AMD WILL BE
COMMON IF WE HAVE TO ADJUST TIMING. TSRA IN LA AND AR TERMINALS
WILL LIKELY BE ADDED LATER AS STORMS MOVE INTO THE AREA.
