AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
655 PM EDT WED APR 30 2025
SYNOPSIS
HIGH PRESSURE OFF THE COAST WILL BRING UNUSUALLY WARM TEMPERATURES
THROUGH THE REST OF THE WEEK. THE HIGH WILL SLIP FURTHER
OFFSHORE TOWARDS THE WEEKEND AS A COLD FRONT APPROACHES, WITH SHOWER
AND THUNDERSTORM CHANCES INCREASING FROM THE WEST. THIS FRONT
MAY LINGER NEAR THE AREA NEXT WEEK, KEEPING CLOUDINESS AND
SHOWERS AROUND.
UPDATE
NO MAJOR CHANGES MADE TO THE PUBLIC/MARINE FORECASTS. NEW
AVIATION DISCUSSION FOR 00Z TAFS BELOW.
NEAR TERM /THROUGH THURSDAY/
THE MID LEVEL RIDGE THAT HAS BEEN OVERHEAD WILL PROGRESS EASTWARD
THROUGH THE NEAR TERM PERIOD, BECOMING BETTER ALIGNED WITH THE
SURFACE REFLECTION. SOMETIMES THIS CAN CLEAR THE WAY FOR SOME
VORTICITY CENTERS AND RAIN CHANCES BUT MODELS CONTINUE TO SHOW WARM
AND RAIN-FREE WEATHER. GIVEN THAT PW VALUES ARE FORECAST TO FALL
BELOW 1.0" THIS SEEMS MORE THAN PLAUSIBLE. TEMPERATURES WILL COOL TO
NEAR DEWPOINTS TONIGHT BUT THERE IS JUST ENOUGH OF A SOUTHERLY
BREEZE TO PRECLUDE FOG IN ALL GUIDANCE. TOMORROW'S UNSEASONABLY WARM
HIGHS WILL BE SIMILAR TO TODAY'S.
SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/
DRY CONDITIONS COME TO AN END AS THE AXIS OF MOISTURE FROM THE SW
MOVES OVERHEAD THURSDAY NIGHT. A SHORTWAVE WILL PASS TO OUR NORTH
LATE FRIDAY INTO FRIDAY NIGHT WITH A PULSE OF LIFT AND MOISTURE,
SUPPORTING LOW SHOWER AND STORM CHANCES PRIMARILY INLAND. ANY
RAINFALL WILL BE LIGHT. HIGHS IN THE MID TO UPPER 80S AWAY FROM THE
IMMEDIATE COAST. LOWS IN THE LOWER TO MID 60S.
LONG TERM /SATURDAY THROUGH WEDNESDAY/
THE COLD FRONT CONTINUES TO SLOW DOWN, THOUGH LOCALIZED LOW PRESSURE
ALONG IT WILL CONTINUE TO SUPPORT SHOWER AND STORM CHANCES HEADED
INTO THE WEEKEND. THIS LOW PRESSURE WILL DECREASE CONFIDENCE INTO
EARLY NEXT WEEK AS IT COULD INTERACT WITH AND STALL THE FRONT IN OUR
AREA. HIGHEST CHANCES FOR SHOWERS/STORMS WILL BE DURING THE
AFTERNOONS/EVENINGS. ONCE THE FRONT CLEARS THE AREA TEMPERATURES
WILL BECOME MORE NEAR NORMAL.
