WINDS GENERALLY DRIVEN BY TERRAIN FLOWS. THIS RIDGE WILL ALSO
CONTINUE TO RESULT IN HOT TEMPERATURES AND LOW RELATIVE
HUMIDITIES...WITH GENERALLY POOR OVERNIGHT RECOVERY. SUFFICIENT
HIGH BASED MOISTURE REMAINS IN PLACE TO ALLOW FOR A FEW BUILDUPS
THROUGH EARLY THIS EVENING...HOWEVER THIS MOISTURE DOESNT APPEAR
TO BE ADEQUATE TO SUPPORT THUNDERSTORM ACTIVITY. BY SATURDAY
HOWEVER...THIS MOISTURE SHOULD BE SUFFICIENT TO SUPPORT ISOLATED

REMAIN IN PLACE THROUGH AT LEAST THE MIDDLE OF NEXT WEEK
BRINGING A CONTINUED THREAT FOR SHOWERS AND THUNDERSTORMS.
