Area Forecast Discussion National Weather Service Charleston SC 318 PM EDT Wed May 1 2024
SYNOPSIS
Atlantic high pressure will extend west across the Southeast U.S. into next week.
NEAR TERM /THROUGH TONIGHT/
Mid level trough axis has progressed into the Atlantic with the back edge of the trough and cooler mid level air progressing eastward out of the coastal Carolinas. Latest SPC mesoanalysis shows a narrow corridor of 500-1000 J/Kg MLCAPE along the coast.
Enough low level convergence/instability to pop some convection along the SC coast as well as along a subtle line of convergence from CHS back up to around Lake Marion in inland SC. No lightning thus far, although there are a few enhanced updrafts with cloud ice (per satellite imagery) and some rumbles of thunder yet occur.
Rest of the afternoon: Isolated to scattered showers and potentially some thunder will be the rule until early evening with the best coverage anticipated across southeast South Carolina, and especially the tri-county area. Severe threat remains low, but a brief heavy downpour is possible.
Tonight: Short-wave ridging will build into the southeast through tonight with weak surface high pressure remaining draped across the region. Convection will wane/end quickly this evening with quiet weather thereafter. Biggest concern remains fog possibilities
With light/calm winds
increased surface dewpoints and larger scale subsidence, patchy to areas of fog is a good bet, particularly down through southeast Georgia and perhaps the tri-county area where we are getting a little rainfall late this afternoon. A Dense Fog Advisory may eventually be needed later later overnight/early Thursday morning.
SHORT TERM /THURSDAY THROUGH SATURDAY/
Thursday and Friday: Strong subtropical ridging aloft will dominate the Southeast U.S. both days with the area located along the western flanks of Atlantic surface high pressure centered well offshore.
While low-level moisture will remain somewhat seasonable with dewpoints in the 50s and 60s, broad subsidence aloft and the resulting lack of any meaningful mixed-layered instability will support a mainly dry forecast through the period. A rouge shower can not be completely ruled out Friday afternoon ahead of the sea breeze as the upper ridge shifts offshore and mid-level capping weakens a bit, but chances for anything measurable will likely remain below the mentionable threshold of 20%. A few showers/tstms could drift into into the far inland areas from the west Friday evening as weak shortwave energy passes by to the north and west. Forecast soundings at KRBW, KJYL and KMHP show a steadily weakening mid-level cap during this time as the upper ridge shifts farther out into the Atlantic. Slight chance pops around 20% were maintained across the interior to account for this. Highs will warm into the mid-upper 80s each afternoon away from the beaches with overnight lows dropping into the mid 60s well inland to near 70 at the beaches.
Saturday: The risk for scattered showers/tstms will increase on Saturday as a weak mid-level weakness settles across the Southeast States. Forcing for ascent will remain fairly weak and ill-defined in the vicinity of the weakness per model omega vertical cross- sections, but weak to moderate instability coupled with low-level convergence near a fairly progressive sea breeze circulation and potential convective outflow interactions would support a slightly more active day compared to the previous few where subtropical ridging dominated aloft. 20-60% pops were maintained Saturday with the highest gridded pops clustered well inland ahead of the sea breeze. Highs will warm into the lower-mid 80s.
LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/
The pattern will be more reminiscent of summer next week. The weak mid-level weakness over the Southeast U.S. will quickly begin to fill and push offshore Saturday night into Sunday with broad, subtropical ridging dominating aloft thereafter. The region will remain along the western periphery of Atlantic surface high pressure centered well offshore. This pattern will support a more typical, diurnal convective pattern with activity generally concentrating along/ahead of the afternoon seas breeze with the best rain chances concentrating in the Saturday and Sunday periods with the weakness aloft. Weak shortwave energy is progged to pass by to the north on Monday, but most of the forcing with this feature looks to remain over the Pee Dee into central/eastern North Carolina. Temperatures will slowly rise through the period, peaking in the upper 80s to lower 90s by Tuesday.
AVIATION /18Z WEDNESDAY THROUGH MONDAY/
KCHS/KJZI/KSAV: Showers and possibly a thunderstorm or two are possible this afternoon, primarily at KJZI and KCHS with a lesser chance at KSAV. Given the lower probs for thunder, I have removed the mention from the terminal forecasts with the 18Z forecast and will amened as necessary.
VFR conditions heading into this evening. Development of fog appears likely at all terminals later tonight into Thursday morning. We have introduced IFR visibilities at the terminals with the 18Z forecasts, but there is a risk for LIFR toward Thursday morning. Conditions return to VFR Thursday morning after 13Z.
Extended Aviation Outlook: Flight restrictions possible in overnight/early morning fog and stratus. Isolated to scattered showers and thunderstorms are possible Saturday through Monday.
MARINE
Tonight: Surface high pressure and relaxed pressure gradient will remain in control across the coastal waters resulting in overall lighter winds. Sea breeze push later this afternoon will keep onshore winds slightly elevated until early evening with speeds of 10 to 15 knots. Winds 10 knots or less anticipated tonight.
Late tonight there will be the formation of some fog over land areas, some of which could move into the Charleston Harbor and the Atlantic waters very close to shore.
Thursday through Sunday: There are no major concerns through the period. A broad southerly flow will prevail through the weekend with the local waters located along the western periphery of Atlantic high pressure centered well offshore. Typical sea breeze wind enhancements are expected each afternoon along the land/sea interface and Charleston Harbor. Seas will generally remain 3 ft or less through the period.
