Marine Weather and Tides
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it.
8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue.
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

Area Forecast Discussion National Weather Service Peachtree City GA 631 PM EST Fri Nov 27 2020
UPDATE. Stationary frontal boundary remains across the southern CWA this evening. The front should begin to move north overnight as a warm front. Regional radar shows an area of showers and a few thunderstorms across central AL, moving east. This area of rainfall will push east across the CWA overnight. Have tweaked the pops a bit ahead of the precip. Have also tweaked the hourly temps/dewpoints.
PREV DISCUSSION. /Issued 227 PM EST Fri Nov 27 2020/
SHORT TERM /Tonight through Saturday Night/ . No significant weather impacts expected in the short term period. Main forecast concern is timing of onset of light rain associated with positively tilted short wave currently over the Midwest states. Stationary front associated with previous wave never really pushed as far south as models indicated and currently lying just south of CWA and extending WNW toward western AL. Low clouds already sneaked back into Columbus when all recent guidance indicated they should have been clear all afternoon. Will need to watch this trend as PoPs and clouds may move in faster than forecast this evening. 12Z EC and EC MOS also indicating higher PoPs for tonight so may bump them up a bit more before finishing the shift. No matter the timing still appears that rainfall will be fairly light with total amounts under 0.10 inches in north GA and 0.25-0.50 inches in middle GA. Could see some embedded TSRA but no strong/severe convection expected.
Next round of SHRA/TSRA won't arrive until Sunday with clearing skies from the north Saturday afternoon.
LONG TERM /Sunday through Friday/ . The beginning of the forecast period Sunday will be very active as a closed upper low over the Southern Plains transitions into an open wave as it becomes absorbed into the northern jet stream. As this occurs, a surface low will deepen as it tracks from the Mississippi Valley into the Tennessee Valley by Sunday evening. Widespread rainfall will thus be on the increase from west to east during the day Monday as isentropic lift initially increases as a warm front lifts northward. While some elevated embedded thunderstorm activity is possible through the day Sunday, the risk for any strong or isolated severe thunderstorms will be along and south of the warm front late Sunday evening into Sunday night. Even in these areas, forecast instability appears rather marginal, though plenty of shear will spread across the area. In this low CAPE/high shear environment, the potential for an isolated damaging wind or tornado threat is there, primarily in Middle Georgia Sunday night. Otherwise, healthy rainfall totals can be expected with widespread 1- 2" totals from Sunday into Monday morning with locally higher amounts.
By Monday morning, the strong surface cold front will sweep into the area, rapidly ushering in much colder temperatures for Monday. The dry slot behind the front will bring an initial quick end to the rain. However, the next situation to monitor will be the potential for any wraparound light wintry precipitation Monday evening into Monday night in north Georgia. Rapid cold air advection will bring 850 mb temperatures into the -8 to -10 degree C range by Monday evening, so any lingering light wraparound moisture would be in the form of light snow. At this point, moisture appears quite limited as the cold and drier air rushes in. However, some very light accumulations likely under an inch are possible, primarily in the high elevations of the north Georgia mountains before this narrow window closes.
Tuesday morning will bring the coldest temperatures of the season so far with a widespread hard freeze in north Georgia with low temperatures in the mid-20s. Even central Georgia will experience lows in the upper 20s to lower 30s. This will (finally) bring the first official freeze of the season to the Atlanta and Columbus climate sites. High temperatures Sunday will struggle to crack 40 degrees in north Georgia with mid-to-upper 40s in central Georgia. Dry conditions will persist through Wednesday as high pressure settles overhead with another hard freeze areawide Wednesday morning. Confidence then remains low by the end of the forecast period as the ECMWF indicates a second approaching strong low pressure system by late Thursday into Friday while the GFS remains weaker. At this point will indicate increasing low-end PoPs at the tail end of the forecast.
AVIATION. 00Z Update . A period of MVFR cigs possible as an area of precipitation moves across metro ATL overnight. IFR cigs briefly possible at CSG/MCN. Light and variable winds expected for much of the overnight, but should pick up out of the NW during the day tomorrow. A wind shift back to the east is possible during the mid evening on Saturday.

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.
