SYNOPSIS. A weak area of low pressure will track across southern Georgia today. A strong storm system will effect the region Sunday night into Monday. Cold high pressure will then slowly build in and persist through most of next week.

NEAR TERM /UNTIL 6 AM THIS MORNING/. No major changes with the latest update, at least for this period, as we did increase rain chances/amounts during the second period (Saturday). Otherwise, expect increasing showers from the southwest as moisture and low-level isentropic ascent increase in association with mid and upper-level energy impacting the area. Also can't rule a little bit of thunder due to some weak mid-level instability. Temperatures will generally stay about steady or even rise through daybreak.

SHORT TERM /6 AM THIS MORNING THROUGH MONDAY/. Pops were increased to 60-70% for the morning hours per latest model trends; highest Southeast Georgia, including Savannah Metro Area.

Saturday: Short range guidance indicates that a cold front will remain generally west to east across southern Georgia during the morning. A frontal wave will track along the cold front, with a weak mid-level short wave rippling across SE GA/SC during the morning. HREF indicates a wide band of light rainfall across the forecast area, peaking in coverage during the mid to late morning. The forecast will feature likely PoPs across most of SE GA and along the SC Coast, high to solid chc PoPs inland and north. The greatest QPF should remain along and south of the Savannah River, with a .25-.4 of an inch. High temperatures are forecast to peak in the mid to upper 60s. Dry conditions expect for Saturday night with lows in the 50s.

Sunday: A closed H5 low will open to an amplified S/W over the Mississippi River on Sunday. At the sfc, low pressure is forecast to track from the Deep South Sunday morning to the southern Appalachians Sunday night. A warm front is expected to lift across the forecast area by Sunday afternoon. Scattered to numerous showers should develop as the warm front lift north ahead of the sfc low. High temperatures are forecast to peak in the upper 60s to the low 70s. South-southwest winds are forecast to strengthen across the region Sunday night as a cold front approaches from the west. Forecast soundings from across the CWA indicate that low level helicity is forecast to range from 250-350 m2/s2 Sunday night into early Monday morning. An inversion centered between 900-950 mb should keep SBCAPE limited to less than 500 J/kg. It is expected that a band of showers and embedded thunderstorms will develop along and ahead of the cold front late Sunday night. It is possible that the environment could support a few organized segments of convection within the line, possibly resulting in localized wind damage. SPC day 3 Outlook highlights the area with a marginal risk for severe thunderstorms.

Monday: The sfc cold front is forecast to move east off the coast during the morning hours. H85 CAA will continue through the rest of the day, with values over KCHS expected to fall from 12C at 12Z to around 6C by 0Z Tues. Winds in the wake of the cold front will shift from the west, with frequent gusts into the 20s through the afternoon. High temperatures are forecast to range from the mid 60s inland to around 70 along the coast.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/. Cold, dry high pressure will dominate the region through the period, bringing some of the coldest temperatures we've seen thus far in the season. Frost and/or freezing temperatures are possible especially early Tuesday morning. However, since the local growing season ends December 1st, no frost or freeze headlines will be issued.

AVIATION /06Z SATURDAY THROUGH WEDNESDAY/. KCHS/KSAV: High confidence for the 06Z/28 TAF period in at least MVFR conditions at KSAV, but low confidence in restrictions at KCHS. The risk for MVFR or lower cigs will increase this morning as moisture increases in association with a mid- level system impacting the area. The worst conditions should generally be at KSAV where IFR cigs are possible. IFR vsbys are also possible due to some heavier rainfall through about 18Z, especially at KSAV. Confidence is lower at KCHS so we maintained VFR conditions there for now. VFR cigs could return at KSAV by the end of the period.

Extended Aviation Outlook: Widespread MVFR ceilings, occasional IFR ceilings, expected Sunday afternoon through Monday morning. Visibility will occasionally be reduced by rain showers and isolated thunderstorms. Gusty winds will remain across the terminals Monday and Tuesday.

MARINE. Overnight: Some fog could impact the GA nearshore waters close to the Altamaha River. Otherwise, west/northwest winds are expected to veer northwest to north overnight. Speeds will remain less than 10 kt with seas 1-2 ft nearshore waters and 3-4 ft offshore waters.

Saturday: An area of weak low pressure will track west to east along a cold front across southern GA. This pattern will support steady NE winds and seas between 2-3 ft. In addition, scattered to numerous showers should push across the region Saturday and Saturday evening.

Sunday through Wednesday: Low pressure is forecast to track from the Deep South Sunday morning to the southern Appalachians Sunday night. A warm front is expected to lift across the forecast area by Sunday afternoon. Scattered to numerous showers should develop as the warm front lift north ahead of the sfc low. A strong cold front will sweep west to east across the region Monday morning. Just ahead of the front, south winds will strengthen to around 20 kts, with gusts around gale force across the outer GA waters and possibly portions of the near shore waters. Winds will veer from the west during the daylight hours on Monday, with gusts in the mid to upper 20s. Wave heights will build Sunday and Sunday night, expected to peak between 3-8 ft on Monday. A Small Craft Advisory will likely be needed for all waters beginning Sunday night lasting through at least Tuesday. A Gale Watch may even be needed in some portions of the waters. Marine conditions will then begin to improve Wednesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
