PREV DISCUSSION. /Issued 1203 PM EDT Tue May 26 2020/
Cool easterly surface flow will persist through the day today with widespread clouds and scattered shower activity. While moist easterly/southeasterly flow will continue to funnel moisture across the area, resultant afternoon instability will be rather weak, so only a slight chance for thunder was included this afternoon and evening. With mostly showery precipitation, overall QPF totals through the afternoon should remain on the lighter side.

Morning Forecast Discussion for Tuesday, May 26th .
SHORT TERM /Today through Wednesday/ .
Surface high pressure ridge/wedge will be the dominate weather feature across the area in the short term. Moist low-level easterly flow will remain across North and Central GA through mid week. This continues as the region stays in the transition zone between the upper ridge over the western Atlantic, and the large closed upper low over the central and southern plains states. The wave over south GA/N FL will continue to push northward today spreading showers and isolated thunderstorms across the state. Precip chances look good across the entire area but eastern portions of the state will see the higher chances and most QPF with 1 t0 2 inches expected through Thursday.
With the wedge in place through the short term mid-level lapse rates and instability remain weak to moderate at best today and Wed. There could be some isolated strong storms to marginally severe thunderstorms, but chances are low. Continuing with mainly showers and isolated thunder chances in the forecast.
Temps also remain mild with highs Today and Wed expected in the 70s and lower 80s. Low temps tonight will dip into the 60s.
LONG TERM /Wednesday Night through Monday/ .
A cutoff, low-pressure system will be moving across the Southern Plains into the S. Ozarks to begin the long term period. With a longwave, blocking ridge to east over the Atlantic, it will place the forecast area in broad southerly flow and continuously pump warm, moist Gulf air into the region. This airmass will fuel diurnal thunderstorms each day, primarily in the afternoon and evenings. Highs within this airmass will generally be in the 80s with lows in the 60s.
By Friday, a shortwave is expected within the subtropical jet in the northern CONUS that should pull the cutoff low back into the broader flow, pushing a digging shortwave through the forecast area Friday night into Saturday as it moves off to the northeast. A cold front will follow the shortwave and move through the area on Saturday, followed by high pressure the first half of next week and a break from the afternoon storms.
AVIATION. 18Z Update . MVFR cigs largely persist this afternoon at TAF sites. Gradual cig improvement toward low-end VFR is possible through 20-22z. Degradation back toward lower cigs will begin after 00z with IFR cigs likely after 06z. Scattered showers can be expected this afternoon with some shra potential through the night. Shra coverage will likely again increase Wednesday morning. Winds will remain easterly 6-12kts with sporadic gusts 15-20kts possible this afternoon.
//ATL Confidence . 18Z Update . Medium confidence on cig/precip timing. High confidence on winds.

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.
