WEEK, INCLUDING HIGH SURF AND A HIGH RIP CURRENT RISK. SLOW

DISCUSSION
ISSUED AT 350 PM EST MON DEC 16 2024
UPPER LEVEL RIDGE REMAINS OVER THE EASTERN SEABOARD PERSISTS
THROUGH EARLY ON TUESDAY BEFORE IT STARTS SLIDING EAST. THIS
SUPPORTS ONSHORE WINDS PUSHING MOISTURE ALONG WITH PERIODS OF
SHOWERS AND ISOLATED STORMS ACROSS THE CWA EACH AFTERNOON. AMPLE
CLOUD COVERAGE WILL KEEP TEMPERATURES AROUND 80 DEGREES WITH
OVERNIGHT LOWS IN THE MID 60S DURING THIS TIME. ADDITIONALLY,
ONSHORE WINDS WILL BRING HAZARDOUS MARINE CONDITIONS WITH LARGE
BREAKING WAVES 5-8FT. RESIDENTS AND VISITORS SHOULD REMAIN
CAUTIOUS WITH HIGH RISK FOR RIP CURRENTS CONTINUING INTO THIS
EVENING.
LATER ON TUESDAY INTO WEDNESDAY, MOISTURE WILL CONTINUE TO INCREASE
AS AN UPPER LEVEL DISTURBANCE THAT BRINGS HIGHER RAIN CHANCES
MAINLY OVER THE WATER. THIS FEATURE QUICKLY MOVES AWAY AS
SHORTWAVE DIPS DOWN ACROSS THE PENINSULA THROUGH THURSDAY. IT WILL
BE FOLLOWED BY A BROAD UPPER LEVEL TROUGH PUSHING INTO THE
NORTHEAST INTO FRIDAY. AS A RESULT, DRY AND COLD AIR PUSHES BEHIND
IT AND RAIN CHANCES ALONG WITH TEMPERATURES DROP GOING INTO THE
WEEKEND. OVERNIGHT LOWS GO DOWN INTO THE 40S WITH AFTERNOON HIGHS
WILL RANGE FROM THE LOW 60S TO AROUND 70 DEGREES.
MARINE
ISSUED AT 350 PM EST MON DEC 16 2024
AREA OF HIGH PRESSURE REMAINS IN PLACE KEEPING HAZARDOUS BOATING
CONDITIONS ACROSS THE OPEN ATLANTIC THROUGH AT LEAST TUESDAY
MORNING BEFORE SOME STEADY IMPROVEMENTS FOR THE MIDDLE OF THE
WEEK. LENGTHY SWELL PERIODS INTO TOMORROW FURTHER INCREASE THESE
HAZARDS NEAR OUR INLETS. EASTERLY ONSHORE WINDS HAVE PEAKED, BUT
THEY WILL REMAIN MODERATE THROUGH AT LEAST WEDNESDAY. SEAS 7-12 FT
TODAY, SUBSIDING TO 5-8 FT ON TUESDAY AND 4-6 FT BY WEDNESDAY.
INTRACOASTAL AND INSHORE BOATING WILL BEGIN TO IMPROVE AS WELL,
BUT AT LEAST A MODERATE CHOP WILL PERSIST. SCATTERED TO NUMEROUS
SHOWERS ARE LIKELY THROUGH WEDNESDAY ALONG WITH A LOW CHANCE FOR
LIGHTNING ACTIVITY.
HIGH PRESSURE MOVES OFF INTO THE ATLANTIC THIS WEEK, AND A PAIR OF
COLD FRONTS ARE FORECAST TO APPROACH THE LOCAL WATERS BY THURSDAY
AND FRIDAY. WINDS WILL TURN NORTH-NORTHWEST LATE THIS WEEK AS
SHOWERS BECOME MORE ISOLATED.
