DISCUSSION
KEY MESSAGE 1: BEHIND A DEPARTING COLD FRONT, INCREASED FIRE WEATHER
CONCERNS PERSIST AND COOLER WEATHER WILL OCCUR THROUGH MIDWEEK
BEFORE THE NEXT WARM UP.
THE PREVIOUSLY DISCUSSED COLD FRONT HAS NOW TRAVERSED MOST OF THE
FORECAST AREA EARLY THIS AFTERNOON WITH LITTLE TO NO PRECIPITATION
MAKING IT TO THE GROUND. A COOLER AND DRIER AIRMASS CONTINUES TO
FILTER IN FROM THE NORTHWEST, WITH DEWPOINTS FALLING THROUGH THE
30S. NORTHWEST WINDS ALSO CONTINUE TO BE A BIT GUSTY, WITH SPEEDS
AROUND 15 MPH AND GUSTS BETWEEN 20 AND 30 MPH. GIVEN OUR ONGOING
DROUGHT, THIS MAY CREATE SOME SPOTTY FIRE WEATHER CONCERNS, BUT RH
VALUES AREN'T FALLING FAST ENOUGH TO JUSTIFY THE ISSUANCE OF ANY
HEADLINES OUTSIDE OF THE SC FORESTRY BURN BAN WHICH REMAINS IN
EFFECT UNTIL FURTHER NOTICE. WINDS SHOULD DECREASE OVERNIGHT AND
OVERNIGHT LOWS SHOULD FALL INTO THE 40S WHICH IS MUCH COOLER THAN
WE'VE SEEN OVER THE PAST SEVERAL DAYS. DRY HIGH PRESSURE OVERSPREADS
THE AREA AND SHOULD REMAIN IN PLACE MUCH OF THE UPCOMING WEEK. AFTER
A FEW DAYS OF NEAR NORMAL TEMPERATURES, VALUES WILL AGAIN PUSH ABOVE
NORMAL INTO THE MID 80S WEDNESDAY AND UPPER 80S POSSIBLE THURSDAY
AND FRIDAY. WE MAINTAIN AN ELEVATED FIRE WEATHER RISK THIS WEEK
DESPITE WEAK WINDS OVERALL. MIN RH VALUES WILL BE NEAR CRITICAL
VALUES EACH DAY, GENERALLY IN THE LOW TO MID 20S. NOT TO GET TOO
EXCITED JUST YET, BUT THERE REMAINS A SIGNAL FOR A WETTER PATTERN
BEGINNING AT THE VERY END OF THIS PERIOD AND TOWARDS THE BEGINNING
OF MAY.
AVIATION /18Z SUNDAY THROUGH FRIDAY/
BREEZY AT TIMES THIS AFTERNOON BUT STILL VFR CONDITIONS....
WHAT LITTLE RAIN WAS ASSOCIATED WITH THE COLD FRONT HAS NOW
PASSED EAST OF ALL TERMINALS. WINDS HAVE MAINLY SHIFTED TO THE
NORTHWEST, THOUGH THEY HAVE PERIODICALLY TURNED MORE NORTHERLY.
EXPECT GUSTY NORTHWEST TO NORTH WINDS TO CONTINUE THIS
AFTERNOON, DIMINISHING THIS EVENING INTO TONIGHT AS THE PRESSURE
GRADIENT WEAKENS. LOW CLOUDS SHOULD MOVE EAST OF ALL TERMINALS
DURING THE NEXT HOUR FOLLOWED BY HIGH CLOUDS CLEARING OUT THIS
EVENING. CLEAR SKIES AND LIGHT WINDS ARE EXPECTED ON MONDAY
MORNING.
