Area Forecast Discussion National Weather Service Peachtree City GA 336 PM EDT Fri Jun 12 2020 .SHORT TERM /Tonight through Saturday Night/... A surface front has stalled on the southeastern edge of the forecast area. Low pressure on the boundary is aiding in convection across the area south and east of Macon. The storms have generally been slow moving and there is the potential for some local street flooding this afternoon and evening. Pops in the likely category have been included for late this afternoon and early evening. Otherwise more stable air with lower dew points have filtered into the remainder of the forecast area. Not much change for Saturday although the front may drift closer to the Atlantic Coast. Convection chances continue for east central GA through Saturday evening with pops in the slight chance to chance range. 41 .LONG TERM /Sunday through Friday/... Forecast for next week continues to remain on track. Models continue to show trough with embedded shortwaves/TPVs within a secondary more equatorward jet that will have one of the shortwaves/TPVs get cut off as a Rossby Wave breaks to the west between the two jet maxima over the eastern CONUS. This cut-off low will provide the opportunity for a surface low or offshore wave-like feature to form through mid next week as a strong surface high pressure pushes into New England. This will provide for chances of thunderstorms throughout the week across the CWA, with higher chances to the east where better moisture and forcing will reside, though any vorticity maxima which rotate around the trough will provide for forcing for ascent across the entire area. Timing of these will be unreliable this far out in time. The cut-off low will help to keep southerly flow from returning to the area too quickly. This will in turn keep temperatures pleasant for this time of year with highs forecast to be in the 80s most of the week, creeping into the 90s by the end. This is expected to prevent moisture from returning too quickly as well, with forecast dewpoints in the low 60s and even some 50s(!) to the north. With high pressure over the northeast, and a surface low or wave feature to the south, might have to watch for the potential for a weak CAD to form as well which would further limit temperatures and moisture, as CAD depth may not be properly resolved in global scale guidance. For this package, I've gone with mostly the model blend as everyone seems to be getting along in terms of placement of large scale features, with some minor differences in placement of the cut-off low.
