Area Forecast Discussion National Weather Service Peachtree City GA 1055 PM EDT Wed Jul 19 2017 .UPDATE... Seabreeze moving through our extreme SE sections combined with the arrival of some steeper lapse rates from upper low has resulted in some late developing severe storms. Expect these to continue to isolated and driven mainly by the seabreeze front. As this front progresses west, should see less upper support. Have pops going through 05Z or so and then more tranquil conditions for the remainder of the overnight period. && Deese && .PREV DISCUSSION... /issued 826 PM EDT Wed Jul 19 2017/ PREV DISCUSSION... /issued 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... 00Z UPDATE... Unlike the last few nights...isold SHRA are largely remaining outside the terminals. Still plenty of outflows to generate additional activity so will need to monitor closely next several hours. Same pattern for Thu although perhaps a slightly better chance of storms over MCN and will include Prob30 there. //ATL CONFIDENCE...00Z UPDATE... High on all elements.
