Area Forecast Discussion National Weather Service Charleston SC 325 PM EDT Tue Apr 16 2024

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

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
Tonight: The forecast area will remain under the influence of dry high pressure centered over the western Atlantic. An area of thicker cirrus will shift offshore this evening and should leave us under clear skies for much of the overnight. Cirrus will then increase from the west as sunrise Wednesday approaches. Overnight lows will be warmer than the previous night, with upper 50s and low 60s expected.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/
Larger scale pattern flattens/becomes a bit more progressive across the CONUS for the latter half of the week as a deeper closed low settles into south-central Canada and the Northern Plains region. Surface high pressure centered near Bermuda and extending into the southeast coast will remain the dominant player (fair weather) through the middle of the week although there will be increased higher based cloud cover spreading into the region from the west as the upper level heights flatten and the southern stream jet axis lays out across the Gulf and southeast CONUS region. By Friday, the southern tail of a weakening boundary will press into and potentially stall across the southeast region with modest moisture pooling along and south of the boundary. This will become the focus for lower end precip chances later Friday and heading into the weekend (see below) although impacts are looking minimal at this juncture.

Otherwise, well above normal temperatures will persist (middle 80s to near 90) through the balance of the week with daytime highs a good 10+ degrees above normal.

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/
Overall zonal flow pattern is looking to remain in place across the CONUS through the weekend with a trend toward a bit more troughiness developing through the eastern CONUS early next week with lowering heights across the southeast. As mentioned above, boundary is looking to stall across the southeast at least through Saturday before finally getting shunted down into Florida Sunday into Monday. This will remain the focus for increased precip chances through the weekend and into Monday with the higher chances potentially later Sunday into Sunday night as the boundary gets shoved through the region. Given the overall uncertainty, we are maintaining slight chance to chance precip chances through the period, again with the better chances later Sunday into Sunday night. Drying out later Monday and Tuesday.

Temperatures remain above normal through Saturday, cooling down Sunday through Tuesday.

AVIATION /20Z TUESDAY THROUGH SUNDAY/
VFR conditions will prevail at KCHS, KJZI, and KSAV through 18z Wednesday. Passage of the sea breeze this afternoon will bring a few low end gusts of 15-18 knots beginning around 19-20z.

Extended Aviation Outlook: VFR through Friday. A front stalling across the region may bring occasional flight restrictions late Friday through Saturday.

MARINE
Tonight: Overall, no concerns as south to southwest flow prevails across the local waters. Wind speeds will mostly be no more than 10 knots, except for early in the evening along the land/sea interface where 10-15 knots with gusts to 20 knots will be possible. Seas will average around 2 feet, but could be as high as 3 feet around 20 nm and beyond.

Wednesday through Sunday: High pressure near Bermuda will remain the dominant player through at least Thursday with overall south to southwesterly flow. Winds will be locally enhanced along the coast during the afternoon into the evening with formation of a sea breeze. But with gusts 20 knots or less and seas 2 to 3 feet, marine headlines are not anticipated.

Surface boundary will be pressing into the southeast states later Friday, potentially stalling across the region into the weekend before finally pressing through the region late in the Weekend into Monday. Overall southerly/southwesterly flow will persist through much of the weekend, before shifting into the north/northeast thereafter.
