.DISCUSSION...
AFTER A COUPLE OF WINDY DAYS ACROSS THE AREA...LOOK FOR A MUCH
CALMER YET STILL MILD DAY FOR THE BURN AREA AS AN UPPER LEVEL
RIDGE OF HIGH PRESSURE BUILDS INTO THE REGION. INITIALLY FOR THIS
MORNING...LIGHT WINDS WILL TURN TO THE SOUTH AND INCREASE TO
AROUND 10 TO 12 MPH BY NOON. DURING THE AFTERNOON...DEEP THERMAL
MIXING WILL ALLOW TEMPERATURES TO CLIMB INTO THE 80S WITH HUMIDITY
LEVELS LOWERING BACK INTO A 20 TO 30 PERCENT RANGE. LATER
TONIGHT...A WEAK UPPER DISTURBANCE SLIDING THROUGH THE REGION WILL
BRING A FEW ISOLATED THUNDERSTORMS TO THE BURN AREA ALTHOUGH THE
OVERALL COVERAGE WILL BE LOW. DRY AND MILD CONDITIONS WILL
CONTINUE INTO THURSDAY WITH HUMIDITY LEVELS EXPECTED TO LOWER INTO
A 20 TO 30 PERCENT RANGE ONCE AGAIN. HOWEVER...UNLIKE
TODAY...SOUTH WINDS WILL BE ON THE GUSTY SIDE ONCE AGAIN WITH
SUSTAINED SPEEDS BETWEEN 15 TO 20 MPH WHILE GUSTS UP TO 25 TO 30
MPH WILL BE POSSIBLE.
