.DISCUSSION...AN UNSEASONABLY MOIST SOUTHERLY FLOW WILL CONTINUE
OVER THE AREA THROUGH THE REST OF THE WEEK AS LOW PRESSURE OFF THE
BAJA COAST SLOWLY MOVES EAST. THIS WILL INCREASE THE CHANCE OF
SHOWERS AND THUNDERSTORMS WITH THE BEST CHANCES OCCURRING ON
WEDNESDAY AND THURSDAY.

FOR LATER TODAY AND TONIGHT...A WEAK DISTURBANCE ALOFT SOUTH OF THE
INTERNATIONAL BORDER WILL MOVE NORTH INTO COCHISE COUNTY. THIS
FEATURE WILL BRING A BETTER CHANCE OF THUNDERSTORMS TO THE BURN AREA
LATER THIS AFTERNOON INTO THIS EVENING. IF A THUNDERSTORM IMPACTS
THE BURN AREA...IT WILL BE CAPABLE OF PRODUCING STRONG GUSTY WINDS
WHICH BE RATHER ERRACTIC.
