Area forecast discussion, Sep 23, 3:21 PM EDT, 44 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 321 PM EDT Sat Sep 23 2017 .SHORT TERM /Tonight through Sunday Night/... Isolated convection developing as expected this afternoon over north GA and areas near KCSG. This activity will move SW as it did last two days and again could be strong and perhaps approach severe levels, though intensity likely will be a bit weaker than yesterday as SBCAPE currently 1000-2000 J/kg. Yesterday's SBCAPE closer to 2000 J/kg. After convection dissipates after 9pm, no significant weather impacts expected in the rest of the short term forecast period. 12Z local/NWS hires model guidance including 3km NAM nest in good agreement showing active weather this afternoon and no convection Sunday. Patchy light fog possible again Sun morning but will dissipate after 9a. And until we can get rid of high-amplitude long wave ridging over the eastern CONUS, will continue to see temps well above normal. SNELSON && .LONG TERM /Monday through Saturday/... Made some slight adjustments to late period pops again given some trends on a less robust front for Thursday. Kept thunder in for consistency though one could justify too stable at least for initial passage but progged instability could moderate back from the southeast for the end of the week. Otherwise did a latest refresh on recent blend of guidance and forecast looks largely on track for a nice dry and abnormally warm week. Previous discussion follows... Baker PREV DISCUSSION... /Issued 340 AM EDT Sat Sep 23 2017/ LONG TERM /Sunday Night through Friday/... No real changes to the recent extended forecast trends seen with this model cycle. Medium range models continue to keep the region under a large, but not particularly strong, upper-level ridge through all but the tail-end of the period. Upper trough breaks down the ridge as we head into Thursday/Friday of next week and a surface trough develops across the coastal Carolinas and into central/south Georgia in the wake of Maria as she sweeps up the east coast. Persistent northeast to north low-level flow keeps the region stable through the period, and this stable airmass and the absence of strong upper dynamics or low-level forcing keeps POPs low with this late-week system. Dry and above seasonal normal temperatures reign until then, replaced by more seasonal temperatures as we head into next weekend. 20 && .AVIATION... 18Z Update... Isold SHRA/TSRA possible this afternoon at most forecast points through coverage really too low to mention directly in forecast. Have added VCSH to indicate potential for isold SHRA near airports. VFR conditions expected thru forecast at most locations though MVFR vsbys will be possible at airports prone to radiational fog between 09-12Z. Sfc winds will remain east at 5-10kts daytime and less than 5 kts overnight. //ATL Confidence...18Z Update... Medium confidence on SHRA/TSRA likelihood this afternoon. High confidence on all other elements. SNELSON && .PRELIMINARY POINT TEMPS/POPS...
