DISCUSSION
A RIDGE OF HIGH PRESSURE EXTENDING FROM THE SOUTHWESTERN NORTH
ATLANTIC INTO THE GULF COAST STATES WILL REMAIN IN PLACE THROUGH
FRIDAY, WITH LITTLE TO NO OPPORTUNITY FOR RAINFALL THROUGH AT
LEAST FRIDAY MORNING. HOWEVER, AS THE RIDGE BEGINS TO WEAKEN AND
LOW-LEVEL WINDS SHIFT TO THE SOUTH, GRADUAL LOW-LEVEL MOISTURE
RETURN WILL SUPPORT AFTERNOON RH VALUES RISING FROM THE 25-30%
RANGE (TODAY) INTO THE 35-45% RANGE (BY FRIDAY). SMOKE DISPERSION
INDICES WILL BE IN THE VERY GOOD CATEGORY BOTH THURSDAY AND
FRIDAY, DUE TO TRANSPORT WINDS OF 10-15 MPH AND MIXING HEIGHTS OF
7-9 KFT. IT STILL APPEARS AS IF MUCH NEEDED RAINFALL (IN THE FORM
OF SHOWERS AND THUNDERSTORMS) WILL RETURN ON FRIDAY EVENING, WITH
WIDESPREAD WETTING RAINFALL EXPECTED FROM LATE FRIDAY NIGHT INTO
SATURDAY MORNING. THIS WILL BE FOLLOWED BY ANOTHER OPPORTUNITY FOR
SHOWERS AND THUNDERSTORMS ON MONDAY AND MONDAY NIGHT.
FOG POTENTIAL OVER THE NEXT FEW DAYS: PATCHY FOG MAY BRIEFLY
DEVELOP IN NORMALLY FOG-PRONE LOCATIONS DURING THE EARLY MORNING
HOURS ON THURSDAY AND FRIDAY.
POTENTIAL FOR RED FLAG CONDITIONS: GENERALLY LIGHT WINDS WILL
NEGATE THE NEED FOR A RED FLAG WARNING AS AFTERNOON RH VALUES
SLOWLY RISE THROUGH FRIDAY. HOWEVER, FUELS WILL REMAIN DRY THROUGH
THE END OF THE WEEK, RESULTING IN AN ELEVATED FIRE RISK.
