Area forecast discussion, Apr 18, 3:40 PM EDT, 2 hours 39 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 340 PM EDT Tue Apr 18 2017 .SHORT TERM /Tonight through Wednesday Night/... Thunderstorms have become quite prevalent across wedge front this afternoon as forecast for the last 24 hours by Hi-Res models. A rare win for them in the past few weeks. What has not been captured well is the potential for severe storms. Model projections of CAPE have been modest leading up to this event and are just now indicating more robust values. SPC mesoanalysis shows zone of 1500 J/KG across the metro which has been more than enough to get isolated strong updrafts going. With 500 temps not as cold as recent weeks but still around -13C...we are seeing isolated storms exhibit good hail signatures. So should still see activity fire along slow moving front through early evening but storm motion should send it back to the NE. Just enough movement it looks like to preclude any back building storms for significant flood concerns but will need to be monitored closely for the next several hours. Also have seen some indications of pretty good wind signatures given hail and precip loading with the stronger storms thus far. Have kept thunder in for the extreme NE evening through the evening despite some guidance suggesting no available energy there. Seems front may not make as much progress to the SW and instability higher on analysis than suggested by models. After a bout with low clouds in the morning...should see enough breaks in the clouds for additional development by Wed afternoon across the area. Continued cold temps aloft...PW's around 1.40 and CAPE exceeding 1500 J/KG once again all point to scattered activity for the north. Pops may end up being a little low but will let mid shift re-evaluate potential as we will still have a pseudo wedge in place. Deese .LONG TERM /Thursday through Tuesday/... No changes made to the extended forecast. Precip chances Wednesday night and Thursday will be mainly confined to n GA as a CAD airmass erodes with a weak nose of the upper ridge over the area but still potential for a weak short wave to aid precip chances. The European is drier than the GFS and NAM. Forecast temperatures are still running about 7-10 degrees above normal Wednesday night and Thursday. A weak cold front moves into n GA on Friday and becomes stationary. This will lead to the best precip chances over n GA and only small chances for portions of central GA. GFS and European differ rather greatly with the next system Saturday into Sunday with the European much faster bringing a strong cold front across the area Saturday night and early Sunday and the GFS bringing the front across Sunday and Sunday evening. Either way Precip chances increase Saturday night and Sunday with shower and thunderstorm potential across the area into Sunday night. This front is associated with an upper Jet and Deep 500mb trough/low pressure system. The potential for severe weather will be monitored into the weekend and timing of the front will play a significant role. Storm chances will end early Sunday night or sooner if the front is faster with just shower chances lingering into Monday associated with the upper trough/low. Above normal Temperatures will continue until Sunday then cooling to within a few degrees of normal through Monday. BDL/01 && .AVIATION... 18Z UPDATE... SHRA beginning to develop across the ATL terminals along frontal boundary. No TS just yet but likely to develop within the hour and current 18Z to 22Z TEMPO looks good. May be able to trim off an hour or 2 here soon but need to wait to see how activity develops. Although precip should be ending this evening....MVFR and IFR deck will be moving in for the overnight period. Models not quite as aggressive with IFR potential for ATL and have removed for now but kept the MVFR cigs. //ATL CONFIDENCE...18Z UPDATE... Medium on TSRA duration. High on remaining elements.
