.SYNOPSIS...
As an upper level troughing deepens, high pressure will prevail
at the surface into the weekend.
&&
.NEAR TERM /THROUGH TONIGHT/...
Tonight: Dry high pressure will continue to prevail across the
region through the overnight. The forecast remains dry and
temperatures aren`t expected to be quite as cool as they were in
some locations last night. The forecast is for mostly low to
mid 60s for lows, with a few upper 50s possible inland and in
the typical cool spots.
&&
.SHORT TERM /THURSDAY THROUGH SATURDAY/...
As upper-lvl troughing deepens across the eastern CONUS,
surface high pressure situates itself nearby. This will allow
for drier air to creep into the region through the weekend. This
drier air will keep precipitation chances almost to zero,
however it is noteworthy to add that daily chances of showers
across the offshore waters will be possible through the weekend.
Temperatures will be around normal for this time of year as
highs reach into the mid to upper 80s through the weekend, with
overnight lows in the low to mid 60s inland and upper 60s along
the coastline.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
This upper-level troughing will continue through early next
week as the surface high pressure sticks around overhead. Expect
these dry and quiet conditions to persist. Temperatures will
gradually warm back up the upper 80s to low 90s with this
pattern.
&&
.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
The 18z TAF period begins with lingering MVFR stratus at KCHS
and KJZI, while KSAV is seeing mostly scattered MVFR-level
cumulus develop. The stratus at KCHS and KJZI has been slowly
lifting over the last few hours, and satellite imagery suggests
it will scatter out through mid afternoon. We have extended the
mention of MVFR at KCHS and KJZI through 20z. Otherwise, VFR
conditions should prevail through 18z Thursday. Late tonight
model guidance suggests that stratus will develop to the north
and northeast across the Pee Dee region and the Grand Strand,
but current thinking is that it will remain north of KCHS and
KJZI.
Extended Aviation Outlook: Expect mostly VFR through the week,
except for some brief periods of restricted ceilings due to late
night/early morning stratus.
&&
.MARINE...
Through tonight: The pressure gradient continues to relax and
winds continue to diminish. This trend should continue overnight
with winds dropping off to around 10 knots late this evening. A
modest increase back into the 10-15 knot range is expected late
tonight. Seas will continue to diminish as well, dropping to
around 3 feet across the nearshore waters and 3-4 feet in the
outer waters by sunrise Thursday.
Thursday through Monday: Northeasterly winds will persist
through the local waters through the weekend, and expected to
become rather gusty (w/ gusts up to 25 kts possible) over the
weekend as the surface pressure gradient tightens. Seas will be
3 to 4 ft Thursday and then become 5 to 6 ft on Friday night.
Therefore, Small Craft Advisories might be needed over the
weekend into early next week for increased winds and seas.
Rip Currents: The combination of persistent northeast winds,
astronomical factors, and elevated swell will yield a Moderate
Risk of rip currents at all beaches through this evening and
Thursday.
&&
.TIDES/COASTAL FLOODING...
Astronomical tide levels will remain elevated through the rest
of the week due to the recent full moon and today`s lunar
perigee (9/10). Also, total water levels will remain high from
large tidal departures due to the pinched pressure gradient and
elevated northeast winds. As a result, Coastal Flood Advisories
will likely be needed for saltwater flooding across coastal
zones of SE SC and SE GA during the mid-late morning high tide
cycles through late week.
