355 PM EDT Mon Aug 1 2022
.SYNOPSIS...
Hot with isolated storms each afternoon through Wednesday.
Humidity increases late this week and into the weekend with
typical afternoon storm chances as temperatures return to near-
normal. Warmer next week and slightly drier.
&&
.NEAR TERM /THROUGH TUESDAY/...
Latest radar reflectivity loop shows widely scattered showers
and isolated thunderstorms moving across the SC Midlands and
Upstate, and western NC. This activity has moved into parts of
the SC Pee Dee region and northern portions of the NC coastal
plain over the last hour or so. Isolated to widely scattered
convection should continue through this afternoon, mostly for
inland areas, before leveling off by this evening. Lows tonight
in the mid-to-upper 70s.
Tuesday, a trough aloft slowly starts to lift to the northeast.
Meanwhile, Bermuda high offshore maintains precipitable water
values at or above 2.00 inches. A wave of slightly drier air
traverses through from the northwest Tuesday afternoon as the
trough lifts. It'll be hard for convection to take off, but with
moisture present and the usual Piedmont trough and seabreeze in
play, cannot rule out a slight chance for an afternoon shower
or storm. A hot day ahead, with highs in the mid-to-upper 90s
inland, lower 90s at the coast. Daytime mixing should lower the
dewpoints enough where a Heat Advisory is not necessary. But
regardless, it'll be a hot one. Keep up the fluids!
&&
.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/...
A weak trough approaches the area on Tuesday night with a large
scale trough over the northeastern US. Showers on Tuesday will
be few and far between due to dry air throughout, but the
approaching convergence zone with the dissipating trough will
allow a few showers to develop or persist into Wednesday
morning.
Wednesday will act as a transition period with the weak trough
weakening and moving offshore and weak ridging building into the
area. Full sunshine will bring temperatures into the mid and
upper 90s and should allow for isolated to scattered afternoon
convection. Given the overall synoptic setup, afternoon storm
chances will resemble a typical summer afternoon with near-shore
chances surrounding the sea breeze and eastward moving storms
along the inland thermal trough. The best chance for showers and
storms appears to be in northeastern SC.
Diurnal convection comes to an end around sunset and deep-
layer south or southwest flow redevelops on Wednesday night.
Humidity begins to increase with the surface high offshore and
southerly flow. Overnight lows in the mid 70s inland and upper
70s along the coast.
&&
.LONG TERM /THURSDAY THROUGH MONDAY/...
Ridge to the west and to the east will leave an area of
weakness between the two over Alabama, Georgia, and the western
Carolinas on Thursday. The bulk of the rain chances will remain
west of the forecast area on Thursday afternoon, but isolated
showers will remain possible in a Bermuda high southerly flow
regime.
The strongest of these two ridges will continue to build over
the southern Plains late Thursday and Friday. This could bring
the weakness between the ridges into our area over the weekend.
Alternatively, the ridge offshore (Bermuda high) may build
westward and limit shower chances. Still quite a bit of
uncertainty in the forecast, but there does not appear to be
enough negative forcing to limit the potential for an afternoon
storm or shower. Will maintain isolated storm chances for Friday
with a better chance inland, but have trended wetter for
Saturday.
Bermuda ridge appears to build into the region on Sunday and
Monday which should limit shower chances overall as we trend
toward a warmer forecast and another round of above normal
temperatures. The forecast will carry a slight chance to chance
of storms given the uncertainty in the pattern over the weekend.
How this evolves will likely influence the ability of the mid-
level ridge to build southward toward the SC/GA coast.
&&
.AVIATION /20Z MONDAY THROUGH SATURDAY/...
Mostly VFR ceilings for the 18Z TAF period. Possible exceptions
include some rain currently in parts of upstate SC and western
NC. As these widely scattered showers and isolated storms move
east, they could affect KFLO or KLBT. The nature of this
activity is so spotty that there's only confidence in VCSH.
Future amendments might be needed within the next few hours to
address SHRA or TSRA.
Elsewhere, WSW winds continue, occasionally gusting to
20-23kts. Gusts should calm by sunset. Another cumulus deck in
the 4000-6000ft range should show up towards the end of the
period.
Extended Outlook...Low chance for patchy MVFR/IFR low stratus
and/or ground fog mainly inland terminals around sunrise each
morning. Periodic MVFR/IFR expected with isolated to scattered
showers and thunderstorms each afternoon and evening through the
upcoming week.
&&
.MARINE...
Through Tuesday... Southwesterly continue at 15-18kts with
gusts up to 20-22 kts at times. SSE swell remains consistent at
2-4ft, with a combination of medium and long periods.
Tuesday Night through Saturday... Bermuda high maintains
southerly flow 10-15 knots through Wednesday. As a weak trough
approaches the area, gusts up to 20 knots will also be possible
by Wednesday night. Bermuda high will build into the area over
the next several days and the gradient will weaken. Winds become
around 10 knots with gusts to 15-20. Wind waves generally
between 2 and 3 feet through Thursday, becoming around 2 feet
later this week and into the weekend. Southeast Bermuda swell
around 2 feet at 9 seconds.
