DISCUSSION
WE'LL BE UNDER MOSTLY THE SAME DRY AIRMASS TOMORROW, SO RELATIVE
HUMIDITY VALUES WILL AT LEAST FALL TO THE UPPER 20S BY AFTERNOON,
AND THERE IS THE POTENTIAL TO FALL BELOW 20% AGAIN DEPENDING ON
CLOUD COVER. ADDITIONALLY, NORTHWEST WINDS WILL BE STRONGER
TOMORROW AFTERNOON, INCREASING FROM THE NORTHWEST TO SUSTAINED
15-20 MPH AT 20 FT, WITH GUSTS TO 30 MPH. THERE IS A SLIGHT CHANCE
FOR SHOWERS TOMORROW NIGHT AS A FRONT COMES THROUGH, AND THERE IS
A CHANCE (40%) TO SEE AT LEAST 0.10" FROM IT, ALTHOUGH IT WILL BE
LUCK OF THE DRAW DUE TO THE MORE SCATTERED NATURE OF SHOWERS.
