DISCUSSION
KEY MESSAGE 1: NEAR CRITICAL FIRE CONDITIONS LIKELY TODAY.
HIGH PRESSURE CURRENTLY OVER THE REGION SHIFTS OFFSHORE THROUGH THE
EARLY MORNING HOURS INTO THE DAY SUNDAY. AS IT DOES, WINDS SHIFT TO
MORE EASTERLY, BUT ARE EXPECTED TO BE WEAKER THAN SATURDAY DUE TO A
SLACKENING PRESSURE GRADIENT. HOWEVER, WINDS ARE STILL EXPECTED TO
TOP OUT AROUND 10-15 MPH WITH A FEW GUSTS AROUND 20 MPH. WITH THE
WINDS SHIFTING TO THE EAST, SOME MOISTURE RECOVERY IS EXPECTED BUT
STILL REMAIN NEAR CRITICAL LEVELS. THE LOWEST RH VALUES ARE FORECAST
TO BE NORTH AND WEST OF THE I-20 CORRIDOR. IN ADDITION, FUELS REMAIN
INCREDIBLY DRY. AS A RESULT, WE HAVE A FIRE DANGER STATEMENT IN
PLACE FOR THE DAY.
AS A REMINDER, IN CONJUNCTION WITH THE FIRE DANGER STATEMENT FOR
TODAY, SC AND GA HAVE BURN BANS IN EFFECT UNTIL FURTHER NOTICE.
KEY MESSAGE 2: A CHILLY MORNING, BUT THEN TEMPERATURES WARM
THROUGH THE WEEK WITH SLIGHT CHANCES FOR RAIN ENTERING THE
FORECAST.
HIGH PRESSURE OVER THE AREA IS LEADING TO CLEAR SKIES. IN ADDITION
TO THE CLEAR SKIES, VERY DRY AIR IS IN PLACE, ALLOWING FOR
TEMPERATURES TO DROP RATHER QUICKLY. TEMPS ARE DROPPING THE QUICKEST
IN AREAS WITH NO WIND. REGARDLESS, OVERNIGHT LOWS ARE EXPECTED TO BE
SEVERAL DEGREES BELOW AVERAGE ACROSS THE FORECAST AREA. IN THE
PEEDEE, A FEW AREAS OF FROST REMAIN POSSIBLE, SO A FROST ADVISORY IS
IN EFFECT THROUGH 9 AM. THERE IS SOME QUESTION OF HOW MUCH FROST
DOES DEVELOP DUE TO HOW DRY THE AIR IS.
AFTER THIS MORNING, BROAD RIDGING TO OUR WEST BEGINS TO MOVE OVER
THE AREA, EVENTUALLY GETTING TO THE 90-97.5TH PERCENTILE LATER THIS
WEEK LEADING TO WARMING TEMPERATURES THROUGH THE WEEK. GUIDANCE
SUGGESTS THE CENTER OF THIS RIDGE SLIDES OFFSHORE BY MIDWEEK.
MEANWHILE, THE SURFACE HIGH OVER US IS ALSO FORECAST TO MOVE
OFFSHORE. AS A RESULT, OVERALL FLOW TRANSITIONS TO SOUTHWESTERLY,
ALLOWING FOR AN INCREASE IN MOISTURE TO THE AREA. PWAT VALUES BEGIN
INCREASING TO ABOUT 150% OF NORMAL LATER THIS WEEK. WITH THE
MOISTURE IN PLACE AND WARM TEMPERATURES, THE POTENTIAL FOR SOME
DIURNAL SHOWERS OR STORMS ARRIVES AROUND MIDWEEK.
AVIATION /06Z SUNDAY THROUGH THURSDAY/
VFR CONDITIONS WILL CONTINUE THROUGH THE TAF PERIOD.
HIGH PRESSURE NORTH OF THE AREA WILL PUSH OFFSHORE THROUGH THE
DAYTIME HOURS. MAINLY CLEAR SKIES THROUGH SUNRISE, THEN SOME
INCREASING CLOUDINESS LATE MORNING INTO THE AFTERNOON AS SOME MID
LEVEL MOISTURE RETURNS INLAND ON THE BACKSIDE OF THE HIGH. BASES
WILL REMAIN VFR AT OR ABOVE 5KFT. WINDS WILL BECOME MORE EASTERLY
OVERNIGHT, THEN TURNING SOUTHEAST BY LATER IN THE DAY TODAY. SPEEDS
LIGHTER THAN PREVIOUS FEW DAYS, GENERALLY 5 KNOTS OVERNIGHT AND 10
KNOTS THROUGH THE DAYTIME HOURS. WITH DRY LOW-LEVELS AND AT LEAST
SOME LIGHT WINDS THROUGH SUNRISE, FOG SHOULD NOT BE AN ISSUE THIS
MORNING.
EXTENDED AVIATION OUTLOOK...VFR CONDITIONS LIKELY INTO EARLY
NEXT WEEK, THEN RAIN CHANCES RAMP UP BY MID WEEK.
