UPDATE.

12z Aviation update below.

PREV DISCUSSION. /Issued 306 AM EST Sat Jan 25 2020/

SHORT TERM /Today through Sunday/ . The area of fog in eastern portions of the area has been scattering out from west to east as west winds increase so should be out of the CWA prior to sunrise. Some stratocu associated with wrap around moisture near the upper low has been filtering in across north GA and could linger until late morning/early afternoon. Even some very isolated showers have pushed into the far NW in the last hour or two, but not expecting this to continue much longer. Upper trough should lift into the Ohio Valley today and allow for some decreased and more zonal flow aloft and a weak sfc ridge to build into the area. Temps will be slightly below normal today with most of north GA reaching the upper 40s and central GA in the 50s.

An approaching weak shortwave and some increased moisture will advect into the area mainly starting late Sunday. This will allow for increased cloud coverage through the day and some slight to low end chance pops of showers trending in western portions of the area by late afternoon/early evening. Temps should be slightly warmer than today and near climo norms.

LONG TERM /Sunday Night through Friday/. Cool/wet pattern still expected for the bulk of the long term period. 00Z model guidance in a bit better agreement. Cutoff low over NW Mexico now progged for Thurs so forecast uncertainty expected to increase only very late in the period.

First round of rain Sun night/Mon with broad shortwave moving through in strong mean flow. Not a ton of lift but enough for light rain with up to 0.10 inch rainfall. Temps in far NE GA remain above 37F so no mention of rain/snow mix attm. Will need to monitor this in later forecasts.

NW flow for 36-48hrs before next more compact wave moves east along strong southern branch flow. There is some indication of an out-of-phase, fast moving wave in the northern branch that should be far enough ahead to set up cold air damming pattern favorable for light mixed precip in far northeast Wed morning. Have mention of rain/snow mix in higher elevations. QPF overall with this wave very low as low levels will be dry. Could just be sprinkles.

A relatively brief period of sunny weather expected Thurs before next wave from ejected cutoff low arrives. Timing and intensity quite a bit different between model guidance, but should be the strongest of the three with heavier rain but no evidence of any instability or svr threat. Most likely timing is Friday. Again, some indication that temp in far northeast may be cold enough for some light mixed precip so included rain/snow mix in higher elevations for Fri morning.

Condolences to those hoping for dry weather.

SNELSON

AVIATION. 12Z Update . MVFR cigs flirting with the northern sites this morning and could linger until near 17z with FEW/SCT 4-5 kft possible for the afternoon then higher cirrus/alto tonight into Sunday. Winds stay on west side 7-10 kts for most sites. Any precip chances remain beyond the fcst period and start to increase late Sunday.

//ATL Confidence . 12Z Update . Medium on late morning/afternoon cig trends. High on all else.

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.
