UPDATE .

No changes to the forecast needed this morning. Clouds to the west will continue to slowly stream eastward towards the CWA today. Main impact with these clouds will be in terms of our temperatures and whether or not they allow us to reach record breaking temps or not. For now still expecting to reach 75F (old record 74F set back in 2021) as analysis does not depict the thicker clouds to settle in until after peak heating. Otherwise a nice day area wide.

SHORT TERM /Today through Saturday/ .

Near term focus is on potential for some morning fog development given light to calm winds and some low dewpt depressions. Overall thinking any coverage should be patchy and given some run to run consistency in GLAMP guidance, there could be a small area of patchy dense fog in our southwest CWA as well so will monitor trends here in next few hours though so far the lower obs have stayed mainly west and south of the area.

Otherwise a transition to more zonal flow aloft and broad sfc ridge will allow for the unseasonably warm airmass to continue across the area and some areas may flirt with record high temps this afternoon with low to mid 70s expected for much of the CWA. For Saturday, an amplifying weak wave to the west of the area should shift us into SW flow aloft and still allow for above normal temps. While the more enhanced moisture field stays west and the area should remain pop- free, there should be an increase in cloud coverage. This may keep max temps a tad lower than today but just by a degree or two.

LONG TERM /Saturday Night through Thursday/ .

We enter the long term on Saturday morning in a very brief period of zonal flow aloft, ahead of a shortwave trough positioned across the ArkLaTex. Dynamics with this system are marginal at best, and with a dry airmass still in place, the passage of the trough just to our north will only be realized by way of increased cloud cover through Sunday for much of north and central Georgia. Some light showers are possible for the far northwest corner of Georgia as the best moisture clips the area.

A more impressive system follows close behind, with a well-stacked low pressure deepening across the northern Plains to start off the week. As it sweeps across the Great Lakes, a broad cold frontal boundary sets up across the central CONUS. Global models prog the fringes of the front to enter Georgia from the northwest late Monday morning/early Monday afternoon. For now, instability seems to be lacking (<500 J/kg at peak heating Monday) to fuel any widespread severe concerns, but deep layer shear is sufficient to feed the potential for some thunderstorms before the front peters out late Monday night. QPF on the order of 0.25-0.50" is not enough to merit concerns on its own, but an area of strong moisture advection ahead of a trough axis across the SW CONUS follows on the heels of the front. Periods of heavy rainfall are possible beginning Tuesday night, aided by forecasted PWATs north of 1.6"/ well above the max moving average for this time of year, though it remains to be seen the areal extent of the heaviest rain. Current QPF guidance hints at the Euro solution, which favors more widespread rainfall across north and central GA through the latter half of the week. An additional 2-3" inches of rain are possible through Thursday, with highest amounts focused across areas north of I-85. This, coupled with November rainfall totals clocking in at under 50% of normals for much of GA (just 5-20% for south central GA), means inundation of dry soils is possible, and the potential for flooding concerns will need to be monitored in the coming days.

High temperatures remain well above average for this time of year, with just a brief reprieve following the cold frontal passage Monday, dropping to seasonal mid 50s to low 60s, before rebounding back up into the upper 60s-low 70s. Lows on Monday morning will be 15-20 degrees above average thanks to strong return flow, surging into the mid 50s. Otherwise, lows in the 40s prevail for much of the extended.

AVIATION . 12Z Update . Some patchy fog primarily near the southern sites could allow for IFR/LIFR vsbys and cigs this morning, which should improve after 14z. Otherwise mostly clear to FEW/SCT cirrus this morning through today. Possible MVFR cigs (or lower) developing after 06-09z Saturday. Winds west 5-6 kts for much of today (initially calm for some sites), then light on west side or calm this evening, and back to 5-6 kts on west side Saturday.

//ATL Confidence . 12Z Update . Low to medium on lower cig timing/coverage Saturday morning. High on all else.

Baker

AVIATION. 18Z Update . VFR expected the rest of the day and into early Saturday. Increase moisture due to southwesterly surface flow could create some MVFR/IFR CIGS around 11Z tomorrow morning. Confidence in low on how low CIGS in fall. Thus, have left all terminals at MVFR for now. Recovery back to VFR should happen around 15Z and should stay that way through the remainder of the period.

//ATL Confidence . 18Z Update . Low confidence on low CIG timing and development.
