.DISCUSSION...
IT WILL BE ANOTHER DRY AND WARM DAY AT THE BURN SITE WITH NORTHERLY
RIDGETOP WINDS CONTINUING. HUMIDITY RECOVERY WAS POOR AT THE SITE
OVERNIGHT AND EXPECT LOWER HUMIDITY TODAY THAN PREVIOUS DAYS.
WINDS WILL LIKELY BE UPSLOPISH AND A BIT STRONGER THAN THURSDAY
WITH SOME AFTERNOON GUSTS AT 20 FOOT LEVEL REACHING 20 MPH. EXPECT
DOWNSLOPE WINDS TO DEVELOP BY EARLY EVENING BUT HUMIDITY RECOVERY
WILL ONLY BE MODERATE WITH WARMER OVERNIGHT TEMPERATURES. SATURDAY
WILL BE VERY WARM AND UNSTABLE WITH EVEN STRONGER UPSLOPE WINDS
AND A BETTER CHANCE FOR UPVALLEY FLOW BY THE AFTERNOON. AFTERNOON
HUMIDITY WILL FALL SOLIDLY INTO THE TEENS WITH RIDGETOP WINDS
BECOMING NORTHWESTERLY. THESE RIDGETOP WINDS WILL STRENGTHEN SATURDAY
NIGHT AS A COLD FRONT APPROACHES THE AREA. SUNDAY WILL SEE BREEZY
NORTHWEST WINDS BUT COOLER TEMPERATURES AND HIGHER HUMIDITY.
