.DISCUSSION...EXPECT TIMES OF SUN AND CLOUDS TODAY AFTER A COLD
FRONT MOVED THROUGH THE AREA LAST NIGHT. INSTABILITY WILL REMAIN
OVER THE BURN SITE AS COLD AIR ALOFT MOVES OVER THE BURN SITE.
THIS WILL ALLOW GOOD MIXING AS SOUTHWEST WINDS REACH FROM 12 TO 15
MPH AT THE SURFACE. HIGH PRESSURE WILL START BUILDING IN TODAY SO
CAN EXPECT CLEARING INDICES TO LOWER SOMEWHAT DAY BY DAY. THE NEXT
CHANCE FOR ANY PRECIPITATION LOOKS TO BE SUNDAY INTO MONDAY.
