.DISCUSSION...
MONSOONAL MOISTURE AND THE CONTINUED MOVEMENT OF A COLD FRONT WILL
KEEP ISOLATED SHOWERS AND THUNDERSTORMS OVER THE FIRE THIS
EVENING. A WIND SHIFT TO THE NORTH IS EXPECTED TO OCCUR BY 1800 THIS
EVENING OVER THE FIRE...THOUGH WINDS WILL SHIFT BACK TO THE WEST
BY THE LATE EVENING HOURS. INSTABILITY WILL LESSEN WITH THE LOSS OF
DAYLIGHT...ALLOWING ONLY ISOLATED RAIN SHOWERS TO CONTINUE
OVERNIGHT. A COLD FRONT IS THEN SLATED TO MOVE THROUGH THE AREA
BETWEEN 0600 AND 0900 TUESDAY MORNING. WITH THE PASSAGE OF THE
COLD FRONT...EXPECT COOLER TEMPERATURES OVER THE FIRE
TUESDAY...WITH SLIGHTLY ELEVATED HUMIDITY. ASIDE FROM WIND
SHIFTS...WIND SPEEDS WILL REMAIN GENERALLY LIGHT THROUGH THE
PERIOD. AS THE SYSTEM EXITS THE AREA EARLY TUESDAY MORNING...A
MORE STABLE AIRMASS WILL MOVE OVER THE FIRE. THIS WILL BRING DRY
CONDITIONS FOR THE NEXT FEW DAYS.
