.DISCUSSION...

A WEATHER SYSTEM ACROSS THE REGION WILL KEEP SOME LOW CLOUDS IN
THROUGH THE MORNING HOURS...BUT WE ANTICIPATE BREAKUP BY EARLY
AFTERNOON. THIS ALSO MEANS THE SOUTHEAST WINDS THIS MORNING WILL
ALSO SHIFT TO SOUTHWEST BY MID DAY WITH BETTER MIXING. SAME GOES
FOR DEWPOINTS/HUMIDITY. IF CLOUDS FAIL TO BREAK UP...THIS WILL
DELAY THAT TRANSITION. THUNDERSTORMS ARE FORECAST TO DEVELOP BY
MID/LATE AFTERNOON OVER THE AREA AND TRANSITION EAST.
