000 FXUS62 KFFC 191858 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 158 PM EST Sun Feb 19 2017 .SHORT TERM /Tonight through Monday Night/... Ridge of high pressure will dominate the weather pattern over the state through the short term. Winds will shift to the east around the surface high on Monday, drawing Atlantic moisture into the region. As a result, after a sunny day Monday, clouds will increase over the area Tuesday. There is enough low level moisture will provide an opportunity for patchy fog to develop each morning through Tuesday. Next system approaches the area just beyond the short term period. Warming trend expected through the short term, with lows generally in the 40s and low 50s, and highs reaching the mid to upper 70s Monday afternoon. Forecast temperatures are generally 2-3 degrees from record values. Please see the Climate section below for reference. 31 .LONG TERM /Tuesday through Sunday/... Mainly only tweaks to the long term based on the latest guidance. BDL PREVIOUS DISCUSSION... Models in good agreement holding a surface to upper level ridge over the CWA through Tuesday afternoon. Another developing frontal system moves out of the southern and central plains and into the Southeastern U.S. Tuesday morning. This front brings increased chances of showers to the CWA Tuesday afternoon through Wednesday. The forecast models differ a bit on the strength and intensity of this next system but they both show it weakening as it pushes into GA. There is very little instability with it so staying with showers and no mention of thunder. This weakening system keeps increased moisture over the area through the end of the work week so will keep slight chance to chance pops across the area through then. Another short wave and associated cold front will move out of the midwest and into the eastern US Friday. This system is expected to have a little more instability with it so keeping in the mention of isolated thunderstorms for Friday/Friday Night. This second front appears to move east of the CWA Sat and clear things out for Sat afternoon and Sun. 01 && CLIMATE...
