Area Forecast Discussion National Weather Service Peachtree City GA 1038 AM EDT Sat Jun 27 2020 .UPDATE... Aside from a few areas of midlevel virga or light sprinkles, still looks like the main shower/storm chances will be with a weak upper wave traversing north GA later this afternoon into evening and cannot rule out a few strong storms but not expecting severe. The Saharan dust has actually kept quite a few obs with reduced vsbys near 5SM today. Minor near term adjustments to dewpts, otherwise forecast on track and previous discussion follows... Baker && .PREV DISCUSSION... /Issued 746 AM EDT Sat Jun 27 2020/ SHORT TERM /Today through Sunday/... Mostly clear skies over the state this morning with a few showers still lingering across MS and AL. The southeastern U.S. is still under moist west to southwesterly flow so expecting a few weak waves to move across the area though the short term. These waves along with daytime heating and increased instabilities will keep GA in a classic summertime pattern with diurnally driven showers and thunderstorms. Instability indices are marginal today so expecting mainly general thunderstorms with some isolated severe storms. The best location for these storms will be across North and Western portions of the state today, and across the entire area Sunday. PWs stay in the 1.4 to 1.7in range through the short term so any storms that move over an area will drop a decent amount of precip. There continues to be very little shear in this atmosphere so not looking for much in the way of a tornado threat. Temps look to stay near seasonal norms with highs Today and Sunday mainly in the 80s to mid 90s. Lows tonight will be mainly in the 60s to near 70. 01 && .LONG TERM /Sunday Night through Friday/... As we transition into next week, models are initially drier than previous runs in response to a developing mid level ridge across the area. In addition, instability is not all that high as relatively warm temps aloft look to curb significant convective development. All this points to low end chance pops for the area for Monday afternoon and temps ranging form the upper 80s to mid 90s. Ridge will get flattened very quickly though on Tuesday as a shortwave moves into the Tennessee Valley. In addition, moisture will be increasing from the south with PWATs approaching 2 inches across Central GA. Will go with likely pops for the entire area even though instability may struggle a bit given abundant cloud cover across the area. Big differences in the evolution of the developing cutoff low over the Tennessee Valley per the latest long term guidance. The GFS keeps the energy bottled up north of the area while the ECMWF sends energy southward into the lower Mississippi Valley. Regardless of the exact unfolding of this event, enough moisture and lift should be present to warrant likely pops through Thu. Deese && .AVIATION... 12Z Update... VFR conditions are expected through the forecast period. Showers are developing this morning but will see another round of thunderstorms this afternoon. They should stay mainly across West and North GA with the ATL area TAF sites being affected this afternoon. Winds will remain out of the W to SW with speeds in the 10-15 kt range. Will see some gust to 20 kts in and around convective activity. //ATL Confidence...12Z Update... Confidence high on all elements. 01 && .PRELIMINARY POINT TEMPS/POPS...
