DISCUSSION
MOSTLY CLOUDY SKY CONDITIONS ARE EXPECTED TO PREVAIL THROUGH SATURDAY
MORNING, WITH SHALLOW MOISTURE LEADING TO A CHANCE (20-40%) OF LIGHT
SNOW SHOWERS AT ANY TIME OF DAY THROUGH SUNRISE SATURDAY. WINDS TODAY
WILL BE LIGHT, GENERALLY FAVORING A NORTHWEST COMPONENT WITH 20-FT
SPEEDS REMAINING BELOW 10 MPH. COMBINED WITH THE CLOUD COVER, THIS
WILL LIKELY IMPACT SMOKE DISPERSAL, KEEPING CONDITIONS WITHIN THE FAIR
CATEGORY TODAY.
WEST WINDS WILL INCREASE SATURDAY WHEN GUSTS 20-30 MPH CAN BE EXPECTED.
SKIES WILL GRADUALLY CLEAR THROUGH THE DAY, AND SMOKE DISPERSAL
CONDITIONS SHOULD BE NOTABLY MORE FAVORABLE.
