IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...
MAIN QUESTION FOR TODAY IS CLOUD COVER AND RATE OF DISSIPATION
OF SAME. WE CURRENTLY EXPECT AN OVERCAST MORNING WITH BREAKS
BY ABOUT NOONTIME AND AT LEAST PARTLY CLOUDY BY IGNITION TIME
OR SHORTLY THEREAFTER. PROBLEM IS...IT'S NOT A VERY STRONG HIGH
SO THERE'S ALWAYS THE CHANCE CLOUDINESS WILL PERSIST LONGER. OF
COURSE THIS WILL INHIBIT DRYING...BUT THINK WE'RE OK WITH
MINIMA NEAR 40 PERCENT. WINDS DEFINITELY LIGHTER THAN YESTERDAY
SHOULD REMAIN BELOW 10 MPH BY THIS AFTERNOON.  WE'LL KEEP AN
EYE AND UPDATE IF NEEDED.
