OTHER SHOWERS ALSO SHOWING UP IN NORTHWEST ALABAMA CLOSER TO THE 5H LOW CENTER. MAIN FORECAST PROBLEM IS WHETHER TO EXTEND FFA FOR TODAY. LOW FFG...MOIST AIR MASS AND DIVERGENCE ALOFT TO THE EAST OF THE UPPER LOW WOULD SUPPORT CONTG WATCH FOR TODAY FROM WHERE THE RAIN IS NOW OCCURRING TO THE NORTH AND WEST. HOWEVER...MODELS IN GEN AGREEMENT THAT WARMER AIR ALOFT WILL BE WORKING SOUTHWARD INTO THIS AREA TODAY...WITH THE MORE UNSTABLE AIR MASS AND BETTER LOW LEVEL CONVERGENCE SHIFTING TO THE SOUTH AND EAST. ADDITIONALLY...AIR MASS IN THE NORTH AND WEST SECTIONS HAS BEEN WORKED OVER PRETTY WELL BY THE PREVIOUS TWO DAYS CONVECTION AND CLOUDS OVER THIS AREA SHOULD HELP TO LIMIT INSOLATION TODAY. THIS WOULD SUGGEST THAT HEAVIER RAINFALL TODAY SHOULD SHIFT TO THE SOUTHEAST OF WHERE PCPN IS CURRENTLY OCCURRING...AND QPF PROGS FROM HPC SUPPORT THIS. SO...ATTM DO NOT PLAN ON EXTENDING FFA FOR TODAY... BUT WL PROBABLY MENTION LOCALLY HEAVY RAINFALL POSSIBLE FOR PORTIONS OF THE AREA.
