Area Forecast Discussion National Weather Service Charleston SC 425 AM EDT Mon Jun 10 2024 .SYNOPSIS... A cold front will gradually sag southward across the forecast area today. The front will become stationary near/along the coast through the rest of the week. && .NEAR TERM /THROUGH TONIGHT/... Early this morning, regional radar composite indicated a large patch of showers and thunderstorms across north-central GA, crossing into SC. The leading isolated cells should track across portions of the far inland GA/SC counties during the pre-dawn hours this morning. The forecast will feature SCHC PoPs during the early morning hours. Temperatures should begin the day in the mid 70s, with a few areas in the upper 70s along the coast. Given steady west winds and strong June insolation, temperatures should rapidly warm across the forecast area this morning. Areas across SE GA could exceed 90 degrees by noon, peaking in the low to mid 90s by early afternoon. A cold front is expected to remain nearly stationary across SE GA this afternoon. Near term guidance indicates that a amplifying H5 H5 trough will reach the western Carolinas and Georgia this afternoon. As a result, a weak frontal wave is forecast to develop across SE GA, likely resulting in winds along the GA and SC coast to shift from east. Sfc dewpoints along the coast are expected to rise into the low to mid 70s this afternoon. Heat index values across extreme SE GA may peak between 100-104. The hot and humid BL will combine with the falling heights aloft to produce a moderately unstable environment this afternoon and evening, especially along the coast. In fact, HRRR forecast soundings indicates that coastal area may see CAPE peak between 2500- 3000 J/kg, with little to no inhibition. North of the sfc low, SRH values may range between 100-150 m2/s2 and effective bulk shear around 50 kts. In addition, DCAPE may range from 1300-900 J/kg this afternoon. The combination of deep instability, shear, and the passage of synoptic scale forcing should result in numerous to widespread thunderstorms this afternoon and evening. Several supercell thunderstorms may develop across the CWA this afternoon and evening, capable of producing large hail and damaging wind gusts. SPC has highlighted most of the forecast area with either a Marginal or Slight Risk today. 0Z HREF parameters suggests that area along and east of I-95 should see the greatest potential for severe thunderstorms. The severe risk will be highlighted in the HWO for both land and marine zones. In addition, PW values around 1.8 inches will be common across the forecast area this afternoon and evening. Organized thunderstorms, especially supercells, may develop heavy downpours, resulting in swaths of 1-1.5 inches of rainfall. Steering flow and a field of moderate DCAPE may result in storm motions up to 40 mph. Tonight, convection will be ongoing across the region this evening, then pushing off the coast late. PoPs will decrease from west to east, ending by the pre-dawn hours. Cooler temperatures expected across the region tonight. Low temperatures may range from the mid to upper 60s inland to around 70 along the coast. && .SHORT TERM /TUESDAY THROUGH THURSDAY/... A positively-tilted upper trough over the eastern CONUS Tuesday will lift out of the Southeast overnight into Wednesday replaced by northwest flow aloft. An area of broad high pressure will be centered to our northwest and will gradually build into our region through the week. A surface stationary front will meander just off or near our coast through the period. This will result in a fairly decent moisture gradient across the area with relatively dry high pressure inland and moisture rich air streaming northeast over the Florida Peninsula and into the Atlantic. Despite the virtually stagnant synoptic pattern, a tricky forecast is in play this week in terms of convection. Showers and thunderstorms should be limited over the coastal waters, but with PWATs near 1.5" over land, there should be enough moisture and instability to generate at least isolated convection along the coast (in proximity to the stationary front). The general thinking is that areas far inland will likely remain rain-free through most of the week. However, an inland (offshore) shift in the boundary could result in greater (lesser) coverage over land with southeast Georgia being the prime location. Any convection that does develop should diminish in the evening. Temperatures will remain nearly constant each day with highs in the upper 80s to low 90s. Lows will range from the upper 60s far inland to the lower 70s near the coast and mid 70s along the beaches both Tuesday and Wednesday night. && .LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/... The general pattern remains largely unchanged for the remainder of the week. Ridging aloft should slide in from the southwest, with surface high pressure across the northeast CONUS and an area of low pressure developing in the southwestern Gulf of Mexico. Scattered showers and thunderstorms associated with a progressive sea breeze are possible in the afternoon/evening each day. Temperatures should range near or slightly above normal through the weekend. && .AVIATION /09Z MONDAY THROUGH FRIDAY/... Tonight: VFR conditions expected across the terminals through this morning. This afternoon, a sfc cold front is expected to become nearly stationary across southern GA. A mid-level disturbance will swing over the region this afternoon, resulting in a weak area of low pressure to develop across SE GA. The low should aid in pooling instability over the Coastal Plain and provide veering winds. The environment north of the low will be suitable for numerous to widespread thunderstorm development this afternoon and evening. Each TAF will feature a TEMPO from 20-24Z for gusty winds and IFR vis during thunderstorms. TSRAs will be featured as the predominate weather from 0-4Z this evening at each TAF. There is some potential for severe wind gusts or hail with the afternoon and evening thunderstorms. Extended Aviation Outlook: Mostly VFR conditions expected; however, isolated convection could bring brief flight restrictions mainly in the afternoon period this week. && .MARINE... Today, a cold front will remain nearly stationary across the marine zones this morning. A weak area of low pressure is expected to develop across SE GA this afternoon, tracking ENE across the waters tonight. Wind directions will vary through today and tonight, with speeds generally between 10 to 15 kts. Seas should remain between 2- 3 ft through today and tonight. The primary concern will be the development of strong to severe thunderstorms across SE GA/SC this afternoon, pushing off the coast late this afternoon and evening. Some of these thunderstorms will be capable of producing winds in excess of 35 kts and large hail. An isolated waterspout will be possible, especially north of Ossabaw Island. Tuesday through Saturday: Broad high pressure inland with low pressure to the south will result in winds shifting predominately out of the east-southeast through the period. Wind speeds, fairly light on Tuesday, will average around 10 kt Wednesday into Saturday. Seas will average 2-3 feet. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None.
