Area Forecast Discussion National Weather Service Charleston SC 405 PM EDT Sun Aug 9 2020

SYNOPSIS. The region will remain positioned between Atlantic high pressure and an inland area of broad low pressure.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. Through Sunset: Radar imagery indicates blobs of thunderstorms across portions of our area. CAMs are in good agreement keeping the convection mostly along the inland moving sea breeze. Though, some convection is also anticipated further inland of the sea breeze. The storms are tapping into abundant instability. SPC Mesoscale Analysis shows MLCAPEs peaking in the 2,500-3,000 J/kg range in the next few hours. Additionally, DCAPEs are in the 800-1,000 J/kg range. Marginally severe pulse thunderstorms with damaging wind gusts are a concern into the evening. Additionally, weak steering flow aloft will equate to very little storm movement. With PWATs ~2", locally heavy rainfall is expected, so flooding of low-lying and poorly drained areas is a concern.

Tonight: A stationary front will remain to the west of our area. Convection over land is forecasted to dissipate during the evening. Then, the focus for convection shifts over the coastal waters. Some showers could brush the immediate coast late tonight, which is where we have slight chance POPs. Low temperatures should range from the low to mid 70s inland and the upper 70s to around 80 degrees at the immediate coast.

SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/. A mid level trough will remain over the region as ridging builds to the west. The sfc pattern should support the formation of a sea breeze both days. Given a broad field of instability and deep moisture, the environment should yield scattered to numerous thunderstorms each afternoon, especially along and west of the sea breeze. Forecast soundings indicate that PW values will range between 2-2.25 inches with storm motions of 10 mph or less. The combination of slow storm motions and the potential for back building storms could result in localized areas of excessive rainfall. High temperatures are forecast to range from 90 near the coast to mid 90s inland.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. Very little change in the large scale pattern is shown by global models through the period as a broad trough persists inland and higher pressure well offshore over the Atlantic. This will continue light southerly winds with afternoon sea breezes each day. Although deep layer moisture will be sufficient with PWs 1.5 to 2 inches, lack of any significant large scale forcing will mean that the sea breeze will continue to be the primary way convection will initiate. Model blended PoPs continue to be in the likely range each afternoon, which is about 20 percent above climo. Continue to feel a little uncomfortable with PoPs in that range so far out. However, the higher blended PoPs collaborate well with surrounding offices. Did adjust PoPs downward by 5-10 percent, especially toward the end of the period. High temperatures will continue near normal, while low temperatures likely to continue a few degrees above normal. Given light steering flow, locally heavy rainfall cannot be ruled out each afternoon.

AVIATION /20Z SUNDAY THROUGH FRIDAY/. 20Z Update: Radar indicates sea breeze thunderstorms over portions of our area. For SAV, since impacts seem more likely, we added a TEMPO for IFR due to TSRA. For CHS, we opted to maintain the VCTS. But if radar trends indicate a direct impact for CHS, then an amendment will be made to add a TEMPO group. Otherwise, the thunderstorms are forecasted to dissipate this evening, followed by a dry night. Though, it's possible some ground fog could occur in areas where there is heavy rainfall. The probabilities of this happening at either TAF site is currently too low to mention. Another round of convection is anticipated Monday afternoon.

Extended Aviation Outlook: Scattered to numerous thunderstorms will develop over the region each afternoon and evening. It is possible that brief flight restrictions could occur at KCHS and KSAV with the passage of any thunderstorm.

MARINE. Tonight: Expect tranquil conditions outside of any convection. S winds around 10 kt this evening will veer to the SW after midnight. Seas will average 1-2 ft.

Monday through Thursday: The sfc pattern will feature high pressure centered over the western Atlantic and broad low pressure inland. This pattern should generally support south winds between 10 to 15 kt and seas between 1-3 ft.
