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 . Updated for Aviation National Weather Service Peachtree City GA 100 AM EST Sun Jan 17 2021
Clouds had largely abated across the Atlanta metro after sunset but trying to return from the west. This would have an impact on mainly the diurnal trends in temps and will adjust the curve slightly for this. Otherwise, looking ahead, hi res wants to indicate more in the way of light snow showers vs just flurries for the far northern tier late Sunday into Sunday night. Not sold on these solutions just yet and will keep current forecast as is but pass on to mid shift to reevaluate.
SHORT TERM /Tonight through Sunday Night/ .
Snow showers are beginning to come to an end across the area as the vortmax responsible is beginning to lift away. Have received some reports of light accumulations across mainly the mountains, though most reports showed nothing more than a trace as snow had to fight very dry air on the way down. Some very light snow showers or flurries may continue from north GA through the metro, but no more accumulations should occur at this point. The other "story" today is the wind, which has gusted upwards of 30 mph in some locations today, and will continue through the afternoon before dying down after sunset.
Large upper level trough that has been parked over the east coast remains in place through the short term. Two more shortwaves look to affect us tomorrow into tomorrow night. The first is a piece of vorticity coming from the Pacific that will string out across the area in the morning, providing enough lift and moisture from some cloudiness early, though not expecting any precipitation from this. Temperatures will rebound a little tomorrow into the mid 40s and 50s after this system passes by. The second is more of a clipper type wave which will drop from the Canadian plains quickly around the larger trough and affect us tomorrow night. This wave may have a little better lift and moisture to work with and could provide for some very light snow overnight Sunday in the mountains once again, similar to the system last night/this morning. Have chosen to introduce some very light snow into the grids for now with no accumulations, as there is some uncertainty around moisture availability for this system.
LONG TERM /Monday through Saturday/ .
The long term period begins on Monday as upper-level flow becomes zonal and surface high pressure builds across the Southeast. Monday, Tuesday, and Wednesday will be dry as the jet stream retreats northward over the Midwest and Mid-Atlantic, and any meaningful upper-level disturbances remain well north of the forecast area.
As an upper-level cut-off low over Baja California becomes an open wave and ejects eastward Thursday through Friday, surface high pressure will shift south of the CWA and upper-level ridging will flatten. Moisture advection around the periphery of the surface high will increase during this time while a surface low lifts northeast out of TX and across MS, AL, and GA. The GFS is faster than the ECMWF and Canadian in ejecting the open wave eastward, and as a result, there are timing differences among the global models in terms of rainfall with this system. Currently have chance PoPs for the entire CWA on Thursday and Friday as the surface low and associated rainfall moves in. The rain looks to move out by Saturday morning with upper-level zonal flow and dry air in its wake.
FIRE WEATHER .
Conditions have been carefully monitored today, given areas of fuel moisture at or below 8% yesterday. So far today, however, fuel moistures have been above 11% and minimum RH has been above critical thresholds. Gusty west winds will relax overnight.
AVIATION . 06Z UPDATE .
BKN-OVC Ceilings should linger across the KATL area taf sites through 15-16z. May be some brief clearing after that until ceilings return during the afternoon ahead of the next short wave. Winds will remain light overnight and increase to 8 to 10kts during the afternoon with some low end gusts possible at KATL.
//ATL CONFIDENCE . 06Z UPDATE . High on all elements except medium to high on ceilings.

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.
