Area Forecast Discussion National Weather Service Peachtree City GA 940 PM EDT Sat Jun 30 2018 .UPDATE... Made a few minor adjustments to the grids for tonight, mainly adjusted the hourly temperature/dew point trends and extended the low POPs a bit across the area. Otherwise, general, overall, trends still look good. 20 && .PREV DISCUSSION... /Issued 750 PM EDT Sat Jun 30 2018/ SHORT TERM /Tonight through Sunday Night/... Scattered showers and thunderstorms continue to develop this afternoon, especially in the vicinity of a weak upper low slowly meandering in the south Georgia/Florida panhandle area. Coverage will increase diurnally through the afternoon before gradually diminishing after sunset. Given a tropical airmass with PWs ranging from 1.6 in north Georgia to over 2" in central Georgia, locally heavy rainfall will be the primary concern with any slow-moving tropical convection. This weak low will be slow to drift westward through the day Sunday. Continued deep tropical moisture characterized by PWs continuing to surge over 2" area wide on Sunday will lead to widespread shower and thunderstorm development. Locally heavy rainfall will again be possible, though the severe threat continues to appear limited as midlevel lapse rates remain unimpressive (sub 6 C/km). Temperatures on Sunday will be held into the mid-80s across the western half of the area given widespread cloud cover and convection while lesser coverage in far eastern portions of the area may allow a few near-90 degree highs. RW LONG TERM /Monday through Saturday/... Deep easterly flow is expected to continue through the middle of next week. The weakness (low pressure) in the ridge will remain in place through Tuesday then will begin to shift west on Wednesday as deep easterly flow sets up aloft. Even at the surface, a weak low pressure across the Florida panhandle on Monday and Tuesday will begin to shift west by Wednesday as the easterly flow continues. By the end of the week, several weak/open waves will be moving west in the flow and move onshore the SE coast, brining raised rainfall chances. Overall, no major changes were needed to the forecast. NListemaa AVIATION... 00Z Update... VFR conditions expected outside of convection through 06Z with MVFR ceilings expected to develop most areas between 06Z and 10Z, lasting through 15-18Z. Some areas of IFR conditions are possible during this timeframe as well. Isolated to scattered convection currently is expected to diminish to isolated at most by 02-04Z becoming more widespread again after 16Z. East winds 6kt or less through 14Z, increasing slightly to 6-10kt after. //ATL Confidence...00Z Update... Continued medium confidence on MVFR/IFR ceilings Sunday morning.
