(This afternoon through Wednesday) Issued at 248 PM EDT Tue Sep 17 2024 Current satellite loop shows the coastal low that move onshore the Carolina coast yesterday is now centered and spinning near the GA/SC/NC boarders. The models show this low center staying fairly stationary for the next 24 hours before moving NE into the Mid Atlantic states Wed night/Thu morning. The low center is weakening and all were expecting is just increased cloud cover for most of North and Central GA through the short term. There may be a few locations across eastern portions of the state that see a showers or two through Wed night but not expecting much in the way of thunder or any heavy downpours from this system. These increased clouds will help to keep high temperatures a bit cooler across north Georgia compared to their central or south GA counterparts. Temperatures north of I-20 will be mainly stay in the 70s to lower 80s Wed with lows in the 50s to lower 60s. Areas south of I-20 will reach the mid to upper 80s Wed. 01 && .LONG TERM... (Thursday morning through next Monday) Issued at 248 PM EDT Tue Sep 17 2024 The period will begin with an upper trough extending from S New England to the E Gulf of Mexico. This feature will weaken and shift slowly SE into the weekend as high pressure builds E along the Gulf Coast. At the surface, a weak quasi-stationary front across the S portion of the area will push SE as high pressure builds along the Eastern Seaboard. This setup will produce a CAD wedge along the E side of the Appalachians as we get late into the weekend, with cooler temperatures and more clouds late in the period. Mostly dry conditions are expected through the period. Thursday`s highs will range from the mid 70s in the NE mountains to the mid to upper 80s across the remainder of the area. These temperatures will generally persist into Saturday, with highs by Monday about 3 to 5 degrees cooler across most of the area. Overnight lows will range from the upper 50s in the NE to the mid 60s across the S through the weekend, with slightly cooler lows by early next week. /SEC && .AVIATION...
