Marine Weather and Tide Forecast for Bamberg, SC

NEAR TERM /UNTIL 8 AM SUNDAY MORNING/
Key Message(s):

- Scattered heavy showers possible in the CSRA and Midlands this evening.

A developing boundary across central GA continues to trigger some heavy showers and thunderstorms within a plume of moderate CAPE. These storms are propagating along this boundary, so don't have much eastward motion to them. There is still 20-30 knots of effective shear in eastern GA, so with the moderate instability, a few strong-severe storms continue to be possible this evening. Flash flooding threat is somewhat reduced compared to last night with PWAT's only 1.5-1.8" across our area.

SHORT TERM /8 AM SUNDAY MORNING THROUGH TUESDAY NIGHT/
Key Message(s):

- Hot and Humid with Above Normal Temperatures Each Day

- Heat Index Values Approaching or Exceeding 100F Each Afternoon

- Daily Thunderstorm Chances Continue

Bermuda high will remain parked over the western Atlantic while a sfc high meanders over the Desert Southwest through the short term.
These two systems will lead to SW'ly flow across the Southeast allowing for an influx of Gulf moisture over the region. This will keep daily shower and thunderstorm chances around late this weekend into early next week. A few strong, sub-severe storms can be expected each day, with isolated severe storms possible each afternoon and evening. The main hazard with any severe storm that develops will be damaging wind gusts. The heat will slowly crank up through early next week, with highs climbing into the upper 80s to lower 80s each afternoon. Heat indices from 96 to 103 degrees F can be expected each afternoon thanks to dewpoints ranging from the lower to mid 70s through the period.

LONG TERM /WEDNESDAY THROUGH SATURDAY/
Key Message(s):

- Above Normal Temps Stick Around with the Warming Trend Continuing through Thursday

- Heat Index Values Approaching or Exceeding 100F Each Afternoon

- Mostly Diurnal Showers and Thunderstorms Expected Each Day

Bermuda high remains parked over the western Atlantic through the period but will retreat eastward a bit as a cold front tracks over the forecast area early Friday into Saturday. The cold front appears to bring very little relief (if any) from the heat and humidity behind it. Highs will range from the low to mid 90s with heat indices ranging from 97 to 103 degrees F each afternoon. Mainly isolated to scattered diurnal showers and thunderstorms can be expected each day through the long term. The severe threat continues to look low but a few strong, sub-severe storms will be possible each day. However, an isolated severe storm or two cannot be entirely ruled out each afternoon/evening. Damaging wind gusts would be the main hazard with any severe storms that manage to develop.

AVIATION /01Z SUNDAY THROUGH THURSDAY/

Convection is mainly confined to the CSRA as we start the forecast with some diminishing showers which may impact AGS/DNL with some MVFR vsbys in light rain, otherwise generally VFR conditions expected all terminals through 06z. Some guidance is hinting at a return of stratus again during the predawn hours with higher confidence at AGS/DNL generally during the 08z-14z time frame. Winds should be light from the south before picking up to around 10 knots after 15z Sunday. Any lingering cig restrictions should return to VFR after 15z with scattered cumulus clouds through the afternoon. Another round of afternoon convection expected.

EXTENDED AVIATION OUTLOOK...Brief restrictions are possible each afternoon/evening into early next week with typical summertime convection. Patchy early morning fog and stratus may also cause some restrictions.

CAE WATCHES/WARNINGS/ADVISORIES
SC...None.
GA...None.
