Area Forecast Discussion National Weather Service Peachtree City GA 358 AM EST Sun Dec 15 2019

SHORT TERM /Today through Monday/.

Current satellite loop shows mainly mid to high level clouds streaming across the area. Because of the very moist soils from yesterdays rains we are seeing some fog developing across the region this morning. Right now the fog is patchy but it is still developing and it is thick. May have to issue a dense fog advisory if it continues to grow over the next few hours. Any fog that develops will diminish after sunset. Looking at a warming trend in the short term with high temps getting up into the 60s to near 70 today and into the mid 70s Monday. This warming trend is mainly associated with the warm southerly flow setting up today and continuing through Monday afternoon. This flow is setting up ahead of developing system (now over the Central Plains) that will begin to push precip into NW GA Monday evening. This southerly flow will also increase moisture over the area so increased cloud cover this afternoon and Monday can be expected. With the increased moisture, rising temps, and a frontal system moving in, Instability indices increase also. Could see some isolated thunderstorms Monday evening as the system moves in but nothing severe expected.

01

LONG TERM /Monday Night through Saturday/.

An active start is on tap for the long-term forecast period as the next storm system moves affects the area. As a surface low lifts northeast across the Tennessee Valley Monday night into Tuesday morning, the trailing strong cold front will push into the forecast area. The risk for severe thunderstorms continues to be a concern during this time frame ahead of the front. While the best instability/shear overlap remains to our west during the day Monday (where SPC's Day 2 outlook has Enhanced and Slight risk outlook areas), abundant low-level wind shear and at least marginal instability will translate eastward into the forecast area by late Monday into Tuesday morning. Thus, the threat for damaging wind gusts as well as perhaps a brief spin-up tornado risk will need to be monitored during this time frame. For this reason, SPC currently includes much of the western portion of the CWA in a Marginal Risk on Day 2. Additionally, locally heavy rainfall totals will be possible, especially across north Georgia where localized totals could reach 2".

The cold front will clear the area from west to east through the day Tuesday. Strong cold air advection behind the front will usher in a return to below normal temperatures by Wednesday morning with subfreezing temperatures likely for much of the area both Wednesday and Thursday mornings. Temperatures will moderate back to near normal from Thursday into Friday with dry weather likely to persist at least into Friday. By late Friday into Saturday, the next approaching upper trough appears to bring increasing rain chances, though models diverge on the evolution and timing of this system.

RW

AVIATION. 06Z Update . Ceilings and VSBYS ranging from VFR to IFR across the area. Most locations are VFR and should stay that way with some brief periods of MVFR ceilings around daybreak. Ceilings will get back up into the VFR range by 15-17z. Winds will stay out of the West to Southwest at 8kt or less through the period. VSBYs will be up and down this morning with some patchy fog across the area. VSBYs will get up into and stay in the VFR range shortly after sunrise. No precip expected.

//ATL Confidence . 06Z Update . Confidence high on all elements.

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.
