Area forecast discussion, Jul 19, 3:43 PM EDT, 3 hours 24 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 343 PM EDT Wed Jul 19 2017 .SHORT TERM /Tonight through Thursday Night/... Isolated to scattered showers have developed this afternoon but these will quickly fade away after sunset leaving dry conditions through Thursday morning. Models are pretty consistent in developing a closed H5 low off the Georgia coast and bringing it inland Thursday afternoon. This will bring isolated to scattered showers/tstorms to central Georgia Thursday afternoon and into the evening hours. Ridging aloft over the Tennessee Valley should prohibit convection and will continue a dry forecast for north Georgia for Thursday. Models are also consistent in bringing some of the warmest temperatures to the region so far this season. Max temps across most of the CWA will reach into the mid 90s Thursday afternoon with Heat Index values reaching 100 to 104, not quite Heat Advisory criteria but nonetheless it will be a hot one for anyone working outdoors. 17 && .LONG TERM /Friday through Wednesday/... Only made minor adjustments to the extended forecast to refresh various elements, with the large portion of the grids continuing to be on track with latest model solutions. Still need to watch potential for heat index values to reach Advisory criteria on Friday. Seasonal pops expected through the weekend ahead of an approaching frontal boundary impacting the state next week, which will keep good chance pops in through Wednesday night. 31 && .AVIATION... 18Z Update... VFR conditions will continue through the forecast. Cu field will continue this afternoon, dissipating this evening with a repeat on Thursday. Isolated showers will continue through this afternoon and have added VCSH to all forecasts through this afternoon. Winds will be light northwest to west through the forecast. //ATL Confidence...18Z Update... High on all elements. 17 && .PRELIMINARY POINT TEMPS/POPS...
