SOUTH FLORIDA WILL ENJOY DRY AND SEASONABLY COOL WEATHER THROUGH
THE START OF THE WEEKEND THANKS IN PART TO A MID-LEVEL TROUGH
SET UP OVER MOST OF THE EASTERN SEABOARD. THE NORTHWEST MID-
LEVEL WINDS WILL BRING A VERY DRY (PWAT < 0.5") AND RELATIVELY
COOL AIRMASS DOWN ACROSS THE FL PENINSULA. EXPANSIVE SURFACE HIGH
PRESSURE BUILDING ACROSS MOST OF THE EASTERN US WILL ALSO KEEP
LOW-LEVEL WINDS NORTHERLY. THIS SETUP WILL KEEP RAIN CHANCES NEAR
ZERO THE NEXT FEW DAYS, AND LEAD TO MOSTLY CLEAR SKIES.
HIGH TEMPERATURES TODAY WILL REACH THE UPPER 70S TO LOW 80S. LOW
TEMPERATURES TONIGHT WILL DROP INTO THE MID 40S ACROSS THE
INTERIOR AND LAKE OKEECHOBEE REGION, WITH UPPER 40S TO LOW 50S
ALONG THE GULF COAST, AND LOW TO MID 50S ACROSS THE EAST COAST
METRO. THE LIGHT NORTHERLY WINDS WILL CREATE APPARENT TEMPERATURES
(WIND CHILL VALUES) THAT WILL BE A FEW DEGREES LOWER. TEMPERATURES
ON SATURDAY AFTERNOON WILL ONLY REACH THE MID TO UPPER 60S ACROSS
THE INTERIOR AND GULF COAST AREAS, WITH UPPER 60S TO LOW 70S OVER
THE EAST COAST METRO.
LONG TERM
(SATURDAY NIGHT THROUGH NEXT THURSDAY)
ISSUED AT 150 PM EST FRI DEC 20 2024
EXPANSIVE SURFACE HIGH PRESSURE WILL CENTER ITSELF OVER THE
NORTHEAST STATES FOR THE SECOND HALF OF THE WEEKEND AND EARLY NEXT
WEEK, ALLOWING FOR WINDS TO SHIFT TO AN EAST/EAST-NORTHEAST
DIRECTION IN SOUTH FLORIDA. THIS WILL KICK START A MODERATING
TEMPERATURE TREND AS THE COOLER TEMPERATURES GIVE WAY TO
INCREASING DAILY HIGHS BACK INTO THE UPPER 70S AND NEAR 80 ACROSS
MOST AREAS FOR THE MIDDLE OF NEXT WEEK. ADDITIONALLY, DURING THIS
SAME TIME FRAME EARLY NEXT WEEK, LONGWAVE TROUGHING WILL RE-
DEVELOP OVER THE SOUTH-CENTRAL CONUS AND CAUSE MID-LEVEL FLOW TO
START SHIFTING SOUTHWESTERLY, WHICH WILL BEGIN TO ADVECT SOME
LEVEL OF MOISTURE BACK INTO THE SOUTH FLORIDA REGION. PWATS WILL
BE ON THE RISE THROUGHOUT THE WEEK, POTENTIALLY BACK TO AROUND 1.5
INCHES. WITH THE ELONGATED TROUGHING PROVIDING SOME FORCING FOR
ASCENT AND A MORE MOIST AIR MASS RETURNING, LOW CHANCES FOR
ISOLATED TO SCATTERED SHOWERS WILL RETURN MOST DAYS THROUGH NEXT
WEEK. THESE SHOWERS WOULD BE SHALLOWER AND OF THE QUICK-HITTER
VARIETY WITH NO REAL THREAT FOR THUNDER. CONDITIONS ARE STILL
EXPECTED TO BE MOSTLY DRY EACH DAY EVEN WITH SLIGHT CHANCES FOR
SHOWERS.
