Area Forecast Discussion...Updated for Aviation National Weather Service Peachtree City GA 135 PM EDT Mon Jul 16 2018 .UPDATE... 18z Aviation update below. 41 && .PREV DISCUSSION... /Issued 345 AM EDT Mon Jul 16 2018/ SHORT TERM /Today through Tuesday/... High PWAT regime continues today along with some aided upper forcing from a weak shortwave, warranting likely pops area-wide peaking with daytime heating which could linger a bit longer into the overnight given how slow the trough axis is to progress. Thermal profiles indicate tall skinny CAPE of 2000-3000 J/kg and given how the lapse rates are not impressive given the well saturated column and how the last several days have trended, thinking severe convection is not anticipated and primarily some strong storms instead. Main threats will be isolated flooding from the precip efficiency, occasional lightning and gusty winds. The greater moisture axis does shift farther south into central GA for Tuesday, though should be enough influence from the aforementioned upper wave and also a weak front approaching the north by late afternoon/evening that will still warrant likely pops for the majority of the area. Storms should have less chance for flood potential given some mid/upper level drier air advecting in and resultant PWATs down to about 1.5 inches. Temp fcst slightly lower today in the upper 80s for most given greater precip coverage then a bit higher Tuesday with some drier columns. Baker && .LONG TERM /Tuesday Night through Sunday/... Medium-range models continue to show an amplifying upper-level pattern developing through the majority of the extended forecast period. Frontal boundary settling into the southern portion of the forecast area as we begin the period concentrates best POPs across the southern half of the area mid-week. Strong short wave and associated surface front should increase POPs areawide as we head into the weekend. With moderate mid-level winds associated with this system, combined with enhanced forcing and at least moderate instability, we will need to keep an eye on the potential for an increased severe thunderstorms threat. Noticeable divergence between the GFS and the ECMWF for the latter portion of the period, but I have kept at least chance POPs through the end of this forecast cycle. 20 && .AVIATION... 18Z Update... Some mvfr ceilings were lingering...but should continue to improve to widespread sct-bkn035-045. Showers and thunderstorms should develop in any location with no real feature to focus on. There is also the potential showers and storms could linger beyond 00z this evening into portions of the overnight but not confident which taf sites would be affected. Winds should remain on the west side...mostly southwesr 5 to 7kt and diminish overnight. Some potential for ifr again overnight with such a moist airmass. //ATL Confidence...18Z Update...
