Area Forecast Discussion
National Weather Service Wilmington NC
324 PM EDT Sat Aug 3 2024
.SYNOPSIS...
Periods of showers and thunderstorms may bring heavy rain to the
area this weekend. Tropical Depression Four should become a
tropical storm before landfall on the Florida Gulf Coast Monday.
Moisture from this system may bring additional heavy rainfall
and flooding across the eastern Carolinas through the middle
portions of next week.
&&
.NEAR TERM /THROUGH SUNDAY/...
Convection in the very near term will wane towards evening as it
has for the last few days due to loss of instability. With a
healthy-by-August standards trough digging though showers could
either persist or return during the overnight hours. Radar
echoes should continue on and off all day Sunday according to
most guidance. The early initiation and added cloud cover will
keep Sunday's high close to climo.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH WEDNESDAY NIGHT/...
The upper level trough that is helping to enhance our weekend
rainfall totals should trickle east and off the Mid Atlantic coast
Sunday night. In "normal" conditions this would lead to a reduction
in convection as deeper moisture and synoptic support departs,
however the approach of Tropical Depression Four (more likely a
tropical storm by this point) will begin to spread deep tropical
moisture in from the south and southeast on Monday. A modest 250 mb
jet streak off the Mid Atlantic coast could serve double duty as an
outflow jet for the tropical storm through Monday.
Tropical storm position forecasts have shifted slower and farther
west in the Monday night through Wednesday night timeframe. While
this has delayed the potential onset of any tropical storm force
winds beyond this portion of the forecast, this has affected
forecast rainfall totals by a lesser degree, particularly across
South Carolina where deep tropical moisture should stream onshore
yielding multiple waves of showers and thunderstorms with heavy
rainfall. WPC has placed a "moderate" Excessive Rainfall Outlook
contour across the Grand Strand area for Monday into Monday night.
Forecast PoPs are obviously quite high through the period: 60-90
percent each period Monday through Wednesday. Forecast diurnal
ranges from highs to lows are only 10-12 degrees due clouds,
widespread precipitation, and an onshore wind direction.
&&
.LONG TERM /THURSDAY THROUGH SATURDAY/...
NHC's 11 AM update tweaked the track of our tropical storm slower
and farther inland for Thursday into Thursday night. The 12z suite
of models have all come in farther west still, potentially
necessitating additional track adjustments with time. The culprit
appears to be the strength of the Bermuda High offshore: watch the
rapid westward movement of the 5880m height contour at 500 mb
between 12z Wednesday and 00z Friday as the ridge strengthens
offshore. The upper ridge axis is forecast to build westward across
the Mid Atlantic states, potentially cutting off the storm's path
out to the northeast and forcing slow movement and potentially a
westward drift with time.
Our forecast continues to show a good potential (50 to 60 percent)
for showers and thunderstorms Thursday into Friday as the storm
should still be located somewhere relatively close by. By Friday
night into Saturday a trough developing across the Great Lakes may
begin to erode the ridge enough to allow the storm and its moisture
to exit to the northeast. Assuming this were to occur on-time,
slightly cooler and drier air could begin to spread southward across
the area behind a weak cold front. This portion of the forecast
continues to have larger than normal uncertainty.
&&
.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
VFR for the remainder of the day only to be interrupted by
thunderstorms. Inland terminals LBT and FLO likely see the best
coverage and have earned a TEMPO early in the period. With the loss
of instability there should be a downswing in coverage and intensity
of storms that will reverse towards daybreak but generally with more
shallow convection.
Extended Outlook... Afternoon/evening MVFR/IFR possible from
storms with the potential increasing through this weekend as a
cold front approaches and stalls over the area. Future tropical
cyclone Debby could bring very heavy rain towards the end of the
period.
&&
.MARINE...
Through Sunday...The Bermuda High will continue to be the
dominant player in the production of winds and seas. Five second
wind waves and a lesser 8 second SE swell will continue, though
the latter does weaken as Sunday progresses according to
spectral wave data.
Sunday night through Thursday...Tropical Depression Four should be a
tropical storm by the time it makes it its Florida Gulf Coast
landfall Monday morning. The anticipated motion of the of the storm
has slowed considerably since yesterday and its forecast track has
shifted westward. This could prevent the core of the storm from
reaching our coastal waters, instead taking a track inland across
South Carolina by Thursday.
South winds 10-15 knots and increasing coverage of showers and
thunderstorms are expected Sunday night, Monday, and Monday night.
By Tuesday wind speeds may begin to increase toward 20 knots south
of Myrtle Beach as the center of the storm reaches eastern Georgia.
The forecast continues to have low certainty for Wednesday and
Thursday largely dependent on the motion of the storm, but there is
a risk for stronger southeast winds potentially reaching or
exceeding Tropical Storm force (34 knots) by Thursday. There is
still plenty of time to monitor this evolving threat which could
include large seas and widespread low visibility in heavy rain.
&&
.TIDES/COASTAL FLOODING...
Other - Rip Currents: There is a high risk of rip currents for
all beaches from north of Myrtle Beach, SC up through Pender
County/Surf City (and further north into MHX forecast area).
Moderate risk of rip current today for Myrtle Beach south to
Georgetown County. Decent south swell will contribute to rip
risk for south-facing beaches, while adding a strong south to
north longshore current for east-facing beaches. Strengthening
southeast swell is responsible for east-southeast facing high
rip risk, along with afternoon high tide and new moon Sunday.
Similar rip risk is expected tomorrow. Moderate to high rip
current risk likely through middle of next week, dependent on
the track of Tropical Depression 4. High Surf Advisory may be
needed by mid-week.
