.DISCUSSION...
EAST TO NORTHEAST WINDS OF 10 MPH... WITH GUSTS AROUND 15 TO 20
MPH... WILL DECREASE SLOWLY THIS AFTERNOON. WINDS WILL ALSO TURN
SLOWLY FROM NORTHEAST... TO EAST... AND FINALLY TO SOUTHEAST THIS
EVENING. THERE IS SOME CONCERN THAT OUR FORECAST TEMPERATURES MAY
BE A FEW DEGREES TOO WARM... AND THEREFORE HUMIDITIES ABOUT 5 TO
15 PERCENT TOO LOW... IF THE LOW CLOUDS FAIL TO BREAK UP AS
CURRENTLY FORECAST.  SIMILARLY... IF THE LOW CLOUDS REMAIN... THE
MIXING HEIGHT WILL BE SOMEWHAT LOWER... AND TRANSPORT WINDS LESS
STRONG.  WINDS AND MOISTURE WILL INCREASE ON SATURDAY...
AND PERSIST INTO SUNDAY. MUCH DRIER AIR IS EXPECTED TO ARRIVE
SUNDAY EVENING.
