.DISCUSSION...
A STRONG UPPER-LEVEL RIDGE OF HIGH PRESSURE WILL DOMINATE THE
REGION THROUGH FRIDAY. LOOK FOR LIGHT TERRAIN DRIVEN WINDS AND
MOSTLY CLEAR SKIES. EXPECT POOR RH RECOVERIES THURSDAY NIGHT.
NIGHTTIME RH RECOVERIES WILL IMPROVE OVER THE WEEKEND AS A WEATHER
DISTURBANCE PUSHES ONSHORE. THIS DISTURBANCE WILL BRING A SMALL
CHANCE FOR ISOLATED DRY THUNDERSTORMS OVER THE FIRE LATE SATURDAY
AFTERNOON INTO SATURDAY NIGHT. THIS FEATURE LOOKS TO COOL
TEMPERATURES A BIT WITH INCREASING RH VALUES EXPECTED FRIDAY
THROUGH THE WEEKEND. A COLD FRONT PASSAGE IS EXPECTED EARLY NEXT
WEEK THAT MAY PICK UP WINDS OUT OF THE WEST...BUT WILL CONTINUE A
COOLING AND MOISTENING TREND INTO MID WEEK.
