DISCUSSION
HIGH CLOUDS ARE EXPECTED TO INCREASE LATE THIS MORNING WITH SKIES
BECOMING PARTLY TO MOSTLY CLOUDY BY EARLY AFTERNOON. SHOWER ACTIVITY
(20% CHANCE) THIS AFTERNOON WILL BE ISOLATED IN NATURE, AND THE
CHANCE FOR WETTING RAIN (>0.10 IN) IS NEAR ZERO. AFTERNOON
HUMIDITIES ARE EXPECTED TO BE IN THE 20-30% RANGE. PREVAILING WINDS
SHOULD BE LIGHT (<10 MPH) EAST/SOUTHEAST DURING THE AFTERNOON.
HOWEVER, HIGH-BASED SHOWERS WILL BE ABLE TO PRODUCE ERRATIC WIND
GUSTS UP TO 35 MPH. SMOKE DISPERSAL WILL BE FAIR FOR A FEW HOURS
THIS AFTERNOON.
THERE IS NOT A LOT OF VARIATION IN CONDITIONS FOR WEDNESDAY AND
THURSDAY. SHOWER CHANCES ON WEDNESDAY LOOK TO BE VERY SIMILAR TO
TODAY'S, ISOLATED IN NATURE WITH LITTLE OR NO RAIN REACHING THE
GROUND. HOWEVER, SMOKE DISPERSAL WILL BE VERY GOOD WEDNESDAY
AFTERNOON. LITTLE TO NO CLOUD COVER IS EXPECTED ON THURSDAY AND
SHOWER CHANCES WILL DECREASE TO 10-20%. WINDS WILL FOLLOW A DIURNAL
PATTERN EACH DAY, STARTING OUT NW/DOWNSLOPING IN THE MORNINGS BEFORE
BECOMING E-SE IN THE AFTERNOONS.
