Area forecast discussion, Jul 17, 8:35 PM EDT, 33 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 835 PM EDT Mon Jul 17 2017 .PREV DISCUSSION... /issued 335 PM EDT Mon Jul 17 2017/ SHORT TERM /Tonight through Tuesday Night/... Weak high pressure at the surface and several upper level impulses on the periphery of the forecast area will bring a chance of showers and thunderstorms mainly across southern and eastern portions of forecast area. Convection currently developing in vicinity of a weak surface boundary washing out over central GA and over portions of west and north GA where impulses are moving through the upper level flow. Models showing impulses shifting to the south and east through this evening, with best coverage over central and portions of east GA. Given the strength and proximity of the impulse over northeast and east GA, it seems prudent to keep chance pops continuing through the morning hours. The models all show some drying as the upper ridge builds eastward tomorrow, and PWATs drop under 1.5 inches, but with some instability present, will keep slight chances across the north and low chance over southern portions of forecast area. As for temperatures, guidance values are close and will take a blend through the period. Atwell LONG TERM /Wednesday through Monday/... No changes to the long term. High pressure builds over the forecast area through the end of the week and low chance or slight chance pops look okay. Upper level low developing over the northeast Gulf may affect pops for the weekend but for now will leave pops alone. Previous discussion is included below. 41 Previous...433 AM EDT Mon Jul 17 2017 LONG TERM /Tuesday Night through Sunday/... Main frontal system from the short term will have weakened and moved into south GA/N FL by Tuesday night/Wednesday morning. There will still be some mid to lower level moisture across the region even with drier air filtering into the state through the end of the week. Will keep in low chance pops of convection through day 7. With the drier air pushing into the region through the end of the weak...temps will increase into the mid to upper 90s especially across central GA. will have to keep a close eye on heat index values as the weak continues. && .AVIATION... 00Z UPDATE... TSRA complex continues to move through ATL that was generated from outflows and upper level disturbance. Gust to 39kts at the airfield ahead of this activity but should see more tranquil conditions into the first half of the overnight period. Still some potential for IFR to LIFR tonight in the form of developing cigs. HRRR has been really onto this potential as has the NAM and LAMP but MAV continues to indicate lower potential. For now, will lower current forecast to BKN MVFR and adjust downward as needed with subsequent forecasts. //ATL CONFIDENCE...00Z UPDATE... Medium on IFR/LIFR potential. High on remaining elements.
