500mb analysis shows a mid level low center just south of the four corners region of the US. Across the SE states, a ridge of high pressure extends from central Mexico. As the low center moves into the Mississippi River Valley, it should fill leaving an open trough.
The trough, and associated shortwave energy, should shunt to the NE into the Tennessee Valley on Thursday. The ridge will flatten, with zonal flow setting up by late Thursday.
At the surface, a frontal boundary stretches from the eastern Great Lakes back through the Lower Mississippi River Valley into central Texas. This front should become more west to east oriented today and settle across the Tennessee Valley. A second cold front will cross the Mississippi River by late Thursday but remain well west of the CWA through the short term.
Pops today and tomorrow should remain in the isold to low end scattered categories and highest in the vicinity of the west-east oriented front. For today, lapse rates across far north Georgia will be moderately steep during the afternoon. Along with the steep lapse rates, there will be plenty of moisture and surface CAPE available.
There really isn't anything at the surface to focus convection (front stays to the north), so any lift at the surface would be mesoscale in nature. An isolated strong storm will be possible today, especially across the higher terrain of north Georgia.
Isolated strong to severe storms are possible on Thursday as the front approaches from the west (and any line out ahead of the front).
This will be my last forecast package and AFD. It has been an honor and a privilege to serve the American public for over 30 years.
Choosing meteorology as a career was one of the best things I ever could have done. The current generation of meteorologists are some of the best and brightest that I have ever worked with and you are being left in good hands.

Key Messages
- A cold front will bring increasing shower and thunderstorm coverage, primarily Friday into Saturday.
- A few strong to severe thunderstorms are possible, primarily on Friday.
- Cooler, drier conditions are still favored early next week.
On Friday, moisture will be on the increase across the area ahead of a cold front, leading to increasing rain chances. This front will make progress toward the southeast on Friday as an upper wave swings from the Upper Midwest into the Great Lakes. The trend over the last several forecast cycles is for slightly slower forward frontal progression from Friday into Saturday, leading to a more extended time frame for shower and thunderstorm potential. Coverage will thus be highest across the northwest half of the area on Friday with diurnally-enhanced convective coverage peaking during the afternoon and evening. Forecast SBCAPE trends have nudged higher the last couple of forecast cycles (probabilities of reaching 2000 J/kg increasing), so thunderstorms are a good bet. Shear continues to be the limiting factor for more widespread severe weather, so generally a more isolated potential for any severe continues to be expected on Friday.
With the aforementioned slower frontal progression (particularly among ECMWF solutions), PoPs have continued to trend upward markedly for Saturday. Instability appears considerably more limited on Saturday, so the threat for any severe appears low at this time.
While there is still model discrepancy, drier air is more likely to begin to filter into at least north Georgia on Sunday behind the front. Generally cooler and drier conditions are favored into early next week amid an omega block pattern over the US with surface high pressure dominant over the region. Lows will be more pleasant - largely in the 50s, though some 40s could sneak into far north Georgia, and highs will in the upper 70s to lower 80s.
