Area Forecast Discussion National Weather Service Peachtree City GA 738 AM EDT Sat Jul 15 2017 .PREV DISCUSSION... /Issued 421 AM EDT Sat Jul 15 2017/ SHORT TERM /Today through Sunday/... A weak low pressure trough is situated across central GA early this morning. A weak cold front is also situated across the TN valley and Mid Atlantic. Regional radar shows a few showers and thunderstorms across central GA. Since the airmass remains very moist and unstable, isolated/scattered showers/thunderstorms will remain possible through the early morning hours. The weak frontal boundary will continue to sag southward today and Sunday across north and central GA. The front will be accompanied by a mid level trough axis with plenty of available energy. The tropical-like airmass will remain in place both days, and PWATS at or above 2 inches along and south of the weak front will provide plenty of fuel for storms. In addition to the plentiful moisture, steep lapse rates, abundant surface instability will be in place. Winds aloft are fairly weak, so no major area of organized severe weather is anticipated either day. However, isolated to scattered strong and severe thunderstorms will be possible along and south of the weak boundary this afternoon and Sunday. Damaging wind gusts around 60mph will be possible along with some large hail. With the BL winds being at or below 15kt, storms will be slow movers and capable of producing very heavy rainfall. Localized flooding will be possible. Coverage of storms will be a bit higher today and Sunday as the front will serve as the main focus. NListemaa LONG TERM /Sunday Night through Friday/... The frontal system that moves into N GA in the short term will have moved into central GA by the beginning of the extended. Even with the frontal boundary in place we will still see a mainly diurnal trend as daytime heating will continue to spark convective development each afternoon and evening. The frontal boundary continues moving south into FL into the middle of next week as it also continues to weaken. With the front making little progress southward...expecting a similar trend in the weather Sunday through Tuesday. The front will likely "wash out" on Tuesday with the mid level trough slowly becoming replaced by a large ridge...so convective coverage may be somewhat less Wed through Fri. Expecting a large ridge to build into the area Wednesday with a bit drier air mass across the region. This pattern would mean hotter and drier weather for the end of the extended forecast but given the time of year...isolated convection will still be possible Wed- Fri. Temps will have no problem pushing into 90s across the area. 01 .EQUIPMENT... The KFFC radar is back in operation. Currently, we are monitoring the radar to make sure it is stable. The technicians will return in the morning to make sure everything is still running smoothly and potentially make some adjustments. Intermittent outages Saturday morning are possible as the techs are performing this maintenance. A longer outage is still possible, especially if additional parts need to be replaced. && .AVIATION... 12Z Update... No major changes to the TAF for this forecast cycle. A little more precip coverage expected today. Have tried to nail down the timing a bit, with the hi-res models progging late afternoon/evening with the best coverage. Winds should stay on the west side today, but speeds should be less than 10kt. Patchy mvfr fog is possible overnight. //ATL Confidence...12Z Update...
