SYNOPSIS
High pressure will extend across the region this week. A trough of low pressure will impact the Southeast U.S coast Thursday into Friday.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
A narrow band of light showers continues to track westward across portions of SE GA and adjacent waters as seen on KCLX radar.
As we head into the night, the current showers are expected to dissipate before a second round of light showers arrive around sunrise. The KCHS 00Z sounding observed a strong inversion centered around 750 mb, beneath the inversion winds were E at 15 to 20 kt. Recent runs of HRRR indicated that low-level clouds will move westward over the coastal areas overnight. The strong observed inversion will likely trap moisture and will result in increasing cloud cover near the coastline. The forecast update included increasing cloud cover over portions of SE GA and the SC lowcountry. Also, slight adjustments were made to PoPs and weather.

The latest run of the HRRR forecast soundings indicate that the strong 750 mb inversion through tomorrow and will result to little to no deep instability. The forecast update also included removing the thunderstorm potential for tomorrow. This is in line with SPC's Day 2 Convective Outlook.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/
Wednesday and Thursday: The southern flanks of the expansive upper level anticyclone centered over the eastern United States will begin to buckle just a bit as a well defined TUTT located north of the Greater Antilles approaches the Southeast U.S. coast. The operational GFS is has finally come in line with the rest of the global guidance in keep any surface reflection of the TUTT as an open tropical wave/inverted trough as it moves onshore late Thursday night into the day Friday. Given a modest northeast low-level flow is expected to continue ahead of the approaching tropical wave, steering trajectories favor coastal Georgia for the best chances for measurable rainfall. Still not seeing a strong QPF signal in the various guidance for any concentrated areas of showers given the development of deep convection seems unlikely with the degree of subsidence noted aloft, but isolated to scattered low-topped showers with a few tstms appear likely. Pops 20-40% were maintained for mainly the coastal counties, highest along the Georgia coast. Highs will warm into the upper 80s/lower 90s away from the coast both days with lows Thursday morning dropping into mid-upper 60s well inland to the mid-upper 70s at the beaches. Breezy to locally windy conditions will also persist along the immediate coast and beaches.

Thursday Night and Friday: Rain chances will begin to ramp up late Thursday Night and especially Friday as the approaching tropical waves moves onshore. Shower coverage may lessen a bit Thursday evening as subsidence ahead of the tropical wave spread in from the east, but this will rapidly change as daybreak approaches Friday and the primary wave axis pushes inland. The wave will be accompanied by a ribbon of PWATS in excess of 2 inches. This coupled with some forcing with the weakening TUTT aloft and the convergent/east side of the westward propagating surface wave should be enough to support scattered if not numerous showers with a few tstms. Pops were trended up a bit to 40-60% (highest coast), but given the TUTT will likely be rapidly dampening as it approaches the expansive upper- level anticyclone, there is some hesitancy to go any higher with pops at this time. Further adjustments will likely be needed. Lows Thursday night will drop into the mid-upper 60s well inland to the mid-upper 70s at the beaches. Highs Friday will range from the upper 80s/lower 90s away from the coast with cooler conditions at the beaches.

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/
The tropical wave and associated TUTT aloft will quickly dissipate over the weekend with the region positioned along the eastern flanks of the large subtropical anticyclone. Despite the dissipation of the TUTT, a broad weakness looks to remain through early next week.
This coupled with sea breeze influences and lingering deep-layered moisture featuring PWATS in excess of 2 inches will support scattered showers/tstms each day. The heat will also begin to build through the weekend and especially Monday with highs warming into lower-mid 90s Saturday with the mid-upper 90s into early next week.
The warmest day looks to occur Monday where a few spots far inland could make a run for 100 before the onset of showers/tstms.
Dewpoints do not look to really mix out during this period with heat indices expected to peak 100-103 Saturday, 102-105 Sunday and 105- 110 Monday, highest across the inland portions of the coastal counties.
Heat Advisories could be needed at some point with Monday being the best day for reaching the Heat Advisory criteria of 108.

AVIATION /03Z WEDNESDAY THROUGH SUNDAY/
0Z TAFs: Terminals are forecast to remain VFR through the TAF period. The primary concern will be the timing of gusty east winds at each terminal. Based on MOS, gusts are forecast to return to 20-25kts by 14Z Wed. The gusty conditions are expected to remain through the rest of daylight hours on Wednesday.

Extended Aviation Outlook: Brief flight restrictions are possible in afternoon showers/thunderstorms Wednesday and Thursday, especially at KSAV. Chances of flight restrictions increase at KCHS/KJZI/KSAV terminals Friday and Saturday with lesser chances Sunday.

MARINE
Tonight: A large and strong ridge of high pressure will encompass the coastal waters, with a subtle inverted trough to form nearby.
The pattern will favor an enhanced pressure gradient across local waters through the night, with easterly winds gusting upwards to 20- 25 kt. Favorable long duration onshore fetch will also allow seas to build across local waters, eventually peaking between 4-6 ft across nearshore waters and 5-7 ft across offshore Georgia waters. Small Craft Advisories will therefore be in effect for all local waters outside the CHS Harbor tonight, but a brief lull in winds is possible this evening before 6 ft seas arrive across nearshore waters around midnight.

Wednesday through Saturday: Gusty northeast winds will persist into Friday as a tropical waves approaches from the east and a modest gradient persists over the coastal waters. Northeast winds will average 15-20 kt with gusts to 25 kt during this time. Seas will remain above 6 ft through Thursday night within 20 NM and into Friday evening for the waters 20-60 NM offshore. Small Craft Advisories are in effect for these waters. Seas look to peak 5-6 nearshore waters and 6-8 ft in the offshore waters, mainly on Thursday. Winds in the Charleston Harbor will be near advisory thresholds, but are expected to hold just sky. The need for an advisory there will be reevaluated Wednesday morning. Both winds and seas will begin to diminish Friday night into Monday.

Rip Currents/High Surf: Tybee Island Ocean Rescue is flying double red flags at all Tybee Island beaches where a number of very strong, dangerous rip currents have been observed. The waters have been closed here as a result. Expect the risk for strong and dangerous rip currents to spread into all beaches Wednesday which will persist into Thursday. A high risk for rip currents is being highlighted for all beaches for both days. NWPS breaking wave guidance shows breakers reaching 3-5 ft along the beaches on Wednesday and Thursday, highest in the Folly Beach area. Given only spotty instances of 5 ft breakers are being depicted, the situation for Wednesday looks to marginal for a High Surf Advisory at this time.

TIDES/COASTAL FLOODING
Surface high pressure will remain off the coast of New England with a tight pressure gradient and elevated winds across the South Carolina and Georgia coast. A full moon on 6/22 will also cause the astronomical tides to slowly build. There is a chance that minor coastal flood stage could be reach on the Wednesday and Thursday evening high tides for Charleston Harbor.

Tides at Fort Pulaski are forecast to remain below minor flood stage.
