Area Forecast Discussion National Weather Service Charleston SC 747 AM EDT Fri Jul 1 2022

SYNOPSIS. A surface trough will affect the area through Saturday. Atlantic high pressure will then rebuild Sunday through much of next week.

NEAR TERM /THROUGH TONIGHT/. Around daybreak, Doppler radar indicated a cluster of showers and thunderstorms circulating over the coastal GA waters. The circulation likely is associated with a developing coastal low centered over Grays Reef buoy, 41008. This low should approach shore near Tybee Island later today. The current forecast appears on track.

GOES16 water vapor indicated an extensive plume of deep moisture across the Deep South and Southeast CONUS. SPC mesoanalysis shows the forecast area under PW values of 2.1 inches inland to 2.3 inches over the mouth of Savannah River. Guidance indicates that a coastal trough will remain across GA/SC today. The HRRR and NAM12 generally agree with developing a sfc low over SE GA today, tracking slowly NE along the coast this afternoon and tonight. The HRRR is the most aggressive solution, deepening the low by 3-4 mbs during the daylight hours today.

Applying the generally pattern of a coastal trough with a low over SE GA, the pattern should result in sfc streamlines perpendicular to the Gulf Stream, advecting moisture and instability onshore through the day. NAM forecast soundings indicate that winds between 950- 750mb will remain from 140 degrees around 30 kts. These winds should likely keep the coastal areas supplied with 500-1000 J/kg of CAPE through the day. Combined with LFC between 1.5-2 kft and little to no CIN, convection should readily develop through the day. CAMs generally show SE-NW bands of convection to develop over the nearshore waters and pushing onshore, resulting in training over portions of the coastal counties. The showers and thunderstorms are expected to develop periods of torrential downpours given PW greater than 2 inches, warm cloud thickness in excess of 13 kft. Today, the training storms are expect to concentrate across coastal areas of Jasper, Beaufort, and Colleton Counties. The potential for heavy rainfall across the coastal counties will be highlighted in the HWO.

Temperatures today will be limited by thick cloud cover and high coverage of showers and thunderstorms. High temperatures may only reach around 80 near the coast to the mid 80s far inland.

Tonight, a weak coastal low is expected to slowly track NE along the SC coast. The area along and ahead of the low center is expected to focus bands of training thunderstorms. HREF indicates that the probability of rainfall rates of 3 inches in 3 hrs with 40 km will peak at 50 percent along the SC coast tonight. The potential for excessive rainfall for today and tonight has been highlighted with a slight risk in WPCs Day1 Excessive Rainfall Outlook. The potential for heavy rain tonight will be highlighted in the HWO. Low temperatures should range in the low to mid 70s.

SHORT TERM /SATURDAY THROUGH MONDAY/. An unsettled weather pattern will remain in place this weekend while weak mid-upper lvl ridging persists across the region over weak troughing at the surface. The combination of weak shortwave energy, PWATs at or above 2 inches, onshore flow, and afternoon seabreeze circulations, support scattered to numerous showers/thunderstorms through at least Saturday, and potentially Sunday until mid-upper lvl ridging begins to return through Monday. Given weak flow and deep moisture, showers/thunderstorms could produce heavy rain at times this weekend, mainly during daylight hours. High temps in the mid-upper 80s on Saturday should trend slightly warmer into next week, mainly due to less precip coverage Sunday into Monday (upper 80s to lower 90s). Overnight lows will remain mild, generally in the low-mid 70s away from the immediate beaches.

LONG TERM /MONDAY NIGHT THROUGH THURSDAY/. Mid-upper level ridging will prevail across the Southeast United States while the local area remains position along the western fringes of high pressure across the Atlantic. Even with subsidence across the area, ample moisture will remain across the local area with PWATs of at least 2.0 inches and daily sea breeze circulations triggering scattered showers/thunderstorms each afternoon, more typical of a summertime pattern with the potential of local heavy rainfall. High temps should also trend slightly warmer under high pressure, peaking in the low-mid 90s by the middle of next week. However, highs could struggle to reach the low 90s late next week as mid-upper lvl ridging weakens with approaching mid-lvl energy, resulting in greater precip chances by next weekend. Overnight lows should remain mild, generally in the mid 70s away from the beaches.

AVIATION /12Z FRIDAY THROUGH TUESDAY/. A broad low will bring frequent showers and thunderstorms across the terminals through the 12Z TAF period. Showers will develop into thunderstorms by mid-morning and will likely continue through rest of the TAF period. Thunderstorms, heavy downpours at times, will develop near or over KSAV with the formation of the sfc low between 15-19Z. Thunderstorm coverage should increase over KCHS/KJZI should increase during this afternoon. However, the greatest potential for TSRAs should occur this evening as the sfc low tracks NE along the coast. MOS and forecast soundings indicate that MVFR ceilings may develop at times today, becoming more likely late this afternoon through this evening.

Extended Aviation Outlook: Flight restrictions are likely at times Saturday with numerous showers/thunderstorms shifting across the local area. Brief flight restrictions are possible Sunday through Tuesday, mainly due to afternoon/evening showers and thunderstorms.

MARINE. A coastal trough or low will remain across the nearshore waters today and tonight. The marine zones will see frequent showers and thunderstorms today and tonight. Winds are forecast to gradually strengthen, with southeast winds of 10 to 15 kts with 20kts today. The pressure gradient north of the coastal low is expected to tighten across the nearshore SC waters from late this afternoon through Sat morning, supporting gusts around 25 kts. Small Craft Advisories have been issued for AMZ350 and AMZ352. Seas will build from 2-4 ft today to 3-5 ft tonight.

Saturday through Wednesday: Weak surface troughing will persist during the weekend, before high pressure returns early next week. The overall weather pattern should support a weakening pressure gradient across local waters, but bouts of showers/thunderstorms, mainly during the weekend. In general, southerly flow will prevail, peaking near 15-20 kt Saturday and Sunday, then remaining at 15 kt or less Monday through Wednesday. Seas should average 2-4 ft, although 5 feet seas could briefly touch offshore Georgia waters Saturday night.
