A DEVELOPING LOW PRESSURE SYSTEM OVER TEXAS AND OKLAHOMA IS EXPECTED TO SPREAD RAIN AND THUNDERSTORMS ACROSS ALABAMA TONIGHT AND TUESDAY. MOISTURE HAS BEEN INCREASING ACROSS ALABAMA THIS AFTERNOON. BUT TONIGHT AND TUESDAY THE AIR OVER THE STATE IS EXPECTED TO BECOME SUFFICIENTLY MOIST AND UNSTABLE SUCH THAT SOME THUNDERSTORMS COULD POSSIBLY BECOME SEVERE. AT 320 PM THIS AFTERNOON...SCATTERED STRONG THUNDERSTORMS...SOME SEVERE...HAD ALREADY MOVED INTO NORTHWEST ALABAMA. THUNDERSTORMS WILL INCREASE AS THE WEATHER SYSTEM BECOMES BETTER ORGANIZED TONIGHT AND TUESDAY AND MOVES EASTWARD INTO ALABAMA.
