TO DEVELOP AND THESE STORMS COULD BE HIGH BASED AND PRODUCE GUSTY
WINDS. WINDS WILL BE VARIABLE EARLY THIS AFTERNOON BECOMING
SOUTH/UPSLOPE BY LATE AFTERNOON BUT GENERALLY LESS THAN 15 MPH
UNLESS A THUNDERSTORM APPROACHES THE SITE. EXPECT TEMPERATURES TO
WARM TO NEAR 90 WITH HUMIDITY FALLING TO NEAR 20%. EXPECT WINDS TO
BECOME WESTERLY AND A LITTLE STRONGER THIS EVENING AS THUNDERSTORMS
DECREASE. WEAK UPPER LEVEL HIGH PRESSURE MOVING INTO THE REGION ON

WESTERLY WINDS.
