Area forecast discussion, Mar 11, 3:40 PM EDT, 34 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 340 PM EDT Mon Mar 11 2019 .SHORT TERM /Tonight through Tuesday Night/... Short wave moving through the region into this evening SHOULD finally drive the persistent frontal boundary south of the forecast area as the upper-level flow turns more northwesterly in its wake. Surface ridge shifts far enough east overnight to swing low-level flow easterly ushering in more stable and somewhat drier air mass into the state Tuesday through Tuesday night. Said air mass is not particularly cold, only dropping lows back into the seasonally normal range, and along with ample sunshine Tuesday, allowing afternoon highs to remain above normal. Left thunder in the forecast for central Georgia counties into this evening as sufficient instability available for isolated to scattered deeper convection. However, due to marginal nature of the instability along with only weak forcing, chance for strong to marginally severe storms remains minimal. 20 .LONG TERM /Wednesday through Monday/... Main concerns in long term period are chances and timing of showers and whether there will be any strong/severe convection on Thurs/Fri. Pattern by Wednesday characterized by short wavelength wave-train with large upper low forecast to be located over the OK/TX Panhandle and upper ridge centered over GA/FL. Pleasant warm weather will continue as upper ridge slowly moves east. By late Thurs, clouds will increase as SWly flow aloft moves closer and light showers may affect far NW areas. 12Z model guidance continues with good agreement thru Fri as broad SW flow aloft interacts with front which slowly progresses east across the state. Highest rain chances and instability will be Thurs night and Fri with MLCAPE values approaching 500-750 J/kg. Vertical wind shear strong but not as strong as previous systems. As of this writing, appears severe weather threat will be limited Thurs night and Fri but will continue to monitor. By Sat, significant divergence in model solutions as most guidance pushes front and moisture south and east of CWA while GGEM has much slower progression and more pronounced wave behind this weeks system, moving into MS/AL Sun/Mon. 12Z GFS much slower with next wave and 12Z ECMWF only has very subtle wave progged over gulf coast. With high uncertainty beyond Friday, have left slight chance pops in for SE counties. Later shifts may want to adjust this as new information comes in. SNELSON && .AVIATION... 18Z Update...
