SYNOPSIS
High pressure will extend across the Southeast U.S. through the week and into the upcoming weekend.
NEAR TERM /THROUGH TONIGHT/
Today: Broad high pressure will extend across the region today as a zonal flow dominates aloft. Dry conditions will prevail under sunny skies. 1000-850 hPa thickness schemes support highs in the lower-mid 70s away from the beaches with cooler conditions closer to the coast where a modest sea breeze will push inland by mid-afternoon.
Tonight: A zonal flow will remain in tact aloft. High pressure will shift offshore of the Southeast U.S. coast tonight as a westerly flow atop the Southern Appalachians induces weak lee- side troughing over the South Carolina Upstate into the North Carolina Foothills. The tightest pressure gradient between these two features looks to hold to the north, so expect another night of fairly light winds under clear skies. The risk for a full decoupling of the boundary layer looks highest south of I-16. Lows will range from the mid-upper 40s well inland the upper 50s/near 60 at the beaches and Downtown Charleston.
Similar to this morning, tight thermal gradients will occur near bodies of water where water temperatures are running in the upper 60s to lower 70s.
SHORT TERM /WEDNESDAY THROUGH FRIDAY/
High pressure will persist through Wednesday, before a weak front sinks into the region and possibly stalls in the vicinity Wednesday night into Thursday. Impacts with the front look minimal. A stray shower or two is not out of the question, but probabilities remain too low to include in the forecast at this time. Highs both days near normal in the upper 70s to lower 80s.
Lows mainly in the mid to upper 50s Wednesday night will be a touch more mild in the upper 50s to lower 60s on Thursday night.
High pressure extends south into the region on Friday, although a weak inverted trough could pass through. Another day with slim chances for rain, just perhaps a few brief pop-up showers. PoPs are capped below 15%. Temperatures peak in the upper 70s to around 80.
LONG TERM /FRIDAY NIGHT THROUGH MONDAY/
No weather concerns through the long term period. The center of surface high pressure initially off the Northeast coast will sink south through the weekend and into Monday, remaining the primary feature in control of the local weather. Aloft, ridging will extend over the Southeast. This pattern will support a rain- free forecast and warming temperatures.
AVIATION /06Z TUESDAY THROUGH SATURDAY/
23/06z TAF Discussion: KCHS/KJZI/KSAV: VFR through 24/06z Wednesday.
Extended Aviation Outlook: Prevailing VFR.
MARINE
Today: Northeast winds will veer to the east and southeast this afternoon as a sea breeze develops along the coast. Some sea breeze enhancement is likely near the land/sea interface and Charleston Harbor as the circulation propagates inland. Overall, winds will generally remain less than 10 kt across the entire marine area, possibly as high as 10-15 kt for a few hours in the Charleston Harbor with the sea breeze. Seas this morning will average 2-4 ft nearshore waters out 20 NM with 4-6 ft over the Georgia offshore waters out 20-60 NM where a Small Craft Advisory continues through early afternoon. Seas will subside to 2-3 ft nearshore waters and 4-5 ft over the Georgia offshore waters later this afternoon.
Tonight: South winds will veer to the southwest overnight as high pressure shifts offshore of the Southeast U.S. coast. Winds will average 10 kt for so for most areas, except as high as 10-15 kt for the South Santee-Edisto Beach out 20 NM leg where a slightly tighter pressure gradient will be found. Seas will subside to 2-3 ft nearshore waters and 3-4 ft over the Georgia offshore waters.
Wednesday through Sunday: No marine concerns through the period.
Southerly flow Wednesday becomes northeast then easterly through late week as a weak front sinks into the region. High pressure returns thereafter. Aside from a brief period on Wednesday when winds reach the 15-20 knot range over the Charleston County waters, winds speeds should generally average 15 knots or less and seas 2-4 feet.
Rip Currents: There is a moderate risk for rip currents at area beaches today due to a combination of lunar influences, onshore winds and 2 ft, 10 sec swell. Lingering 9 to 10 second swell and proximity to the full moon will keep an elevated risk of rip currents at all beaches on Wednesday.
EQUIPMENT
The KCLX radar will undergo maintenance today through April 26th. Critical electrical work is planned at the radar site which will require the radar to be offline until the work is completed. Once the radar is taken down, it will remain offline until all electrical work is finalized. The radar is tentatively scheduled to return to service by April 26.
CHS WATCHES/WARNINGS/ADVISORIES
GA...None.
SC...None.
MARINE...Small Craft Advisory until 2 PM EDT this afternoon for AMZ374.
