SYNOPSIS
High pressure will persist through the end of the week. A cold front is then forecast to impact our area this weekend.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/
KCLX radar showed a nice inland progression of the sea breeze earlier before the onset of the strengthening nocturnal inversion. What is left of the sea breeze circulation will gradually unwind over the next few hours. A south to southwest low-level flow will remain in place tonight under clear skies. A few thin cirrus may pass through on occasion, but will not amount to much of anything. Lows will range from the mid-upper 50s well inland to the lower-mid 60s at the beaches and Downtown Charleston.

SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/
Ridging will prevail aloft on Tuesday, slowly transitioning to zonal flow on Wednesday as a mid-level trough traverses the Mid-Atlantic states. Broad ridging will then return on Thursday. At the surface high pressure will dominate, centered over the adjacent Atlantic waters. Wednesday night into Thursday a weak cold front will approach the local forecast area. The high pressure in place will likely prevent the weak front from progressing too far into the local area. There is a very low chance some shower activity could occur Wednesday night, especially inland. However, it is highly unlikely that these showers would reach the surface to produce measurable rainfall. A dry forecast has been maintained.

Temperatures through the period will remain above normal through the short term period, with highs in the mid to upper 80s inland and mid to upper 70s directly at the beaches. Overnight lows will also be above normal, only dipping into the mid to upper 60s.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/
Broad ridging aloft and high pressure at the surface will prevail into the weekend. This weekend a short wave trough is forecast to ripple across the southeastern states, with a cold front at the surface pushing through the local forecast area. PoPs remain in the 20-40% range through the weekend, associated with the frontal passage. Temperatures will remain above normal through Saturday.
Sunday's temperature forecast will be dependent on how far southward the cold front is able to work. The current forecast has above normal temperatures across southeastern GA and near normal temperatures across southeastern SC.

AVIATION /01Z TUESDAY THROUGH SATURDAY/
16/00z TAF Discussion: KCHS/KJZI/KSAV: VFR through 17/00z Wednesday.

Extended Aviation Outlook: Prevailing VFR.

MARINE
Overnight: Sea breeze enhancements in the Charleston Habor are steadily waning. South to southwest winds 10-15 kt will prevail for much of the night with seas averaging 2-3 ft.

Tuesday through Saturday: Conditions through the period are expected to remain below Small Craft Advisory criteria. High pressure will dominate over the local marine waters into the weekend, with SW winds generally 10 to 15 knots. Seas are forecast to average 2 to 3 ft through the period. A sea breeze is expected to form each afternoon along the coast, with the Charleston Harbor gusting to around 20 knots.
