001 FXUS62 KFFC 161115 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 715 AM EDT Tue Apr 16 2019 .PREV DISCUSSION... /Issued 456 AM EDT Tue Apr 16 2019/ SHORT TERM /Today through Wednesday/... High pressure will continue across the CWFA through Wednesday. Dry conditions and seasonable temperatures are expected. High pressure center will begin to shift offshore today and winds will turn more southerly but will light wind speeds will continue. Low level moisture will increase on Wednesday ahead of an approaching cold front. Skies through tonight should be mostly clear with some thin cirrus possible overnight. However, some lower level cu will likely develop on Wednesday, but overall skies should be partly cloudy. No precip anticipated. NListemaa LONG TERM /Wednesday Night through Monday/... Main concern in the extended forecast continue to be the timing and intensity of the next frontal system moving into our area Thursday/Friday. The high pressure ridge in the short term finally pushes off the eastern seaboard Wednesday Afternoon/Evening setting up moist southerly flow ahead of the next developing system. By Thursday morning the system is expected to enter the lower and mid Mississippi river valley and will continue to push east through the end of the work week. The current timing has showers and thunderstorms from this system moving into NW GA around midnight Thu night...pushing precip into the state through daybreak. Instability indices (MLCAPE and deep shear) should be sufficient for strong/svr convection however with near south to north flow aloft, storm mode will most certainly be QLCS with damaging wind as the main threat. Heavy rain may also be expected but duration of rainfall not expected to be too long, less than 12 hours. The best thing we have going for us is it moves into the area in the early morning hours so this system will not have daytime heating to help its severe development. The system will be just about out of our area by 18z Friday. Some of our east central GA counties may have some issues friday afternoon which is why SPC already has most of east GA in a 15 percent risk area for friday already. Once this frontal system moves through, a cooler air mass moves back into the area Sat. High pressure also builds back in for Sun/Monday keeping things dry for days 6 and 7. 01 && .AVIATION... 12Z Update... VFR through the period. The winds will be challenging. Winds should shift E then SE during the mid/late morning and then SW during the mid/late afternoon. Winds may even go back to the SE after sunset. //ATL Confidence...12Z Update... Medium confidence winds. Otherwise, high confidence remaining elements. NListemaa && .PRELIMINARY POINT TEMPS/POPS...
