DISCUSSION
THERE IS AN AREA OF LIGHT RAIN JUST TO THE NORTH OF THE BURN
AREA. BUT, THE BURN AREA IS LOCATED WITHIN A SMALL POCKET OF
CLEARING. THIS CLEARING HAS ALLOWED FOR LOCALLY ENHANCED SUNSHINE
LEADING TO RELATIVE HUMIDITY VALUES THAT ARE AT LEAST 10 PERCENT
LOWER THAN AREAS NEARBY. AS A RESULT, RELATIVE HUMIDITY VALUES
ARE FORECASTED TO REMAIN IN THE LOW TO MID 20S UNTIL OVERCAST
CLOUD COVER MOVES BACK INTO THE BURN AREA WITHIN THE NEXT FEW
HOURS. FOR THE BURN AREA, THE BIGGEST IMPACT THIS AFTERNOON AND
EVENING WILL BE THE INCREASING CLOUD COVER THAT MAY WORK TO RAISE
RELATIVE HUMIDITY VALUES SLIGHTLY TO NEAR 30 PERCENT BEFORE THEY
RISE QUICKLY INTO THE 50S AFTER SUNSET. SURFACE WINDS WILL BE
LIGHT AND SOUTHERLY THIS AFTERNOON BEFORE A COLD FRONT ARRIVES
OVERNIGHT LEADING TO NORTHERLY WINDS FOR TOMORROW. BRIEF CLEARING
SHOULD OCCUR OVERNIGHT BEFORE MORE CLOUDS MOVE IN AHEAD OF THE
NEXT SYSTEM THAT WILL BRING A ROUND OF PRECIPITATION BEGINNING
LATE SUNDAY EVENING.
