Area Forecast Discussion National Weather Service Peachtree City GA 742 AM EDT Sat Jun 29 2019 .UPDATE... Updated for the 12Z Aviation Discussion. && .PREV DISCUSSION... /Issued 402 AM EDT Sat Jun 29 2019/ SHORT TERM /Today through Sunday/... A typical weak-flow summertime type of pattern is in place over the southeastern CONUS to begin the short term period. Temperatures are expected to be near or just above climatological normals areawide, with highs in the upper 80s to mid 90s and low temperatures in the upper 60s and low 70s. Persistent southeasterly flow today will allow for moisture to continue increasing across the forecast area throughout the day today. PWATs will increase to the 1.8 to 2 inch range by late in the afternoon and remain entrenched across the area on Sunday, with the highest of these PWAT values in central Georgia. In the absence of any organized forcing mechanism, convection will once again be diurnally driven today and Sunday, with the highest chances (high-end chance PoPs to low-end likely PoPs) focused across central Georgia where the deepest moisture is expected to located. with weak flow in place along with only modest mid-level lapse rates and instability values, the chance of widespread severe weather is once again expected to be low both today and Sunday. However, some isolated strong storms could be possible each afternoon. King LONG TERM /Sunday Night through Friday/... Upper ridging will dominate the first part of the work week and as the main moisture axis sags farther south, expecting only slight chance pops for isolated showers and storms on the outskirts of the CWA for Monday and Tuesday. The ridge looks to dampen/retrograde westward Wednesday through Friday, which will allow greater moisture return and some exposure to possible enhanced forcing with any impulses tracking along still fairly weak longwave energy from the west. Have general chance pops for scattered convection daily through the second half of the week. Unfortunately, it looks like we cannot guarantee a dry Independence day with 30-40 percent chance of showers and storms. Temps will be above climo norms thru period with most areas in the mid to upper 90s, and with some increased humidity the resultant heat indices could be flirting with Heat Advisory criteria in portions of the area (especially central Georgia) for Tuesday through Friday. Please monitor future updates if this is warranted. Baker && .AVIATION... 12Z Update... Mainly VFR conditions are anticipated through the TAF period, with the exception of some MVFR conditions in central Georgia due to thunderstorm activity and possible MVFR vsby restriction at CSG/MCN tomorrow morning. Scattered showers and thunderstorms are most likely this afternoon after 18Z. With the highest coverage of thunderstorms expected across central Georgia, have introduced a TEMPO for TSRA at CSG/MCN for 19/23Z, and will carry VCSH at the metro TAF sites and AHN for now. A scattered cu field at 030-035 is expected to start developing around 15Z, which will become broken and lift to around 040-050 by 18Z and remain through the afternoon. Light E to SE winds to start the period will increase slightly to 5-7 kts this afternoon, then gradually shift to SW by about 03Z tonight. //ATL Confidence...12Z Update...
