FXUS62 KFFC 210553 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 153 AM EDT Sun Jun 21 2026 ...New 06Z Aviation Discussion... .KEY MESSAGES... - Scattered showers and storms around this afternoon and evening from the I-20 corridor south through Central GA. A few storms may be strong with gusty winds. - Warm and humid conditions with daily chances for showers and storms will continue through much of the upcoming week. && .SHORT TERM... (This evening through Sunday) Issued at 341 PM EDT Sat Jun 20 2026 A frontal boundary remains stalled to the south of the Atlanta metro area, oriented roughly from NW to SE. Numerous showers and thunderstorms have developed along and south of this front. With deep atmospheric moisture south of the front in central Georgia, these storms will be capable of producing locally heavy rainfall, with hourly rainfall rates of 2-3 inches an hour. Furthermore, storms will likely train parallel to the boundary as they move from NW to SE, so strong storms producing heavy rainfall moving over common locations will lead to an increased risk for flash flooding this afternoon and into the evening. Aside from flash flooding concerns, stronger storms that develop will be capable of producing gusty winds and frequent lightning. Because of this, WPC has maintained a Slight Risk (level 2 of 4) for Excessive Rainfall in portions of central Georgia. Comparatively drier conditions are expected to the north of the front, with only isolated thunderstorms possible as far north as I- 20 and even lesser chances in the far northern tier. High temperatures this afternoon will rise into the mid 80s in north Georgia and upper 80s in central Georgia. Overnight into Sunday, southwesterly winds at the low and mid levels will increase ahead of a system over the Midwest. This will bring more warm and moist air into the forecast area from the Gulf as today's frontal boundary advances north as a warm front. Sunday morning will begin with lows in the mid to upper 60s, with low clouds across central and parts of north Georgia amid ample moisture. Warm air advection will have highs climbing into the upper 80s to low 90s on Sunday afternoon. Heat index values will also climb into the upper 90s in portions of central Georgia during the peak heating hours. Subtle mid-level ridging over the region will serve to inhibit convective development, though isolated to scattered showers and thunderstorms (25-40% PoPs) will still break through during the afternoon and evening. King && .LONG TERM... (Monday morning through next Friday) Issued at 341 PM EDT Sat Jun 20 2026 Upper ridging will amplify across the southwest US early this week, placing our area within northwest flow aloft. With a moist airmass in place, expect daily chances for isolated to scattered showers and thunderstorms to continue through much of the week. Perhaps the highest overall chances will occur Monday afternoon/evening (north GA) into Tuesday (western/central GA) as a cold front moves into the area from the north. A few storms could be strong with gusty winds, frequent lightning, and locally heavy rain. Temperatures are forecast to be near average through the week, with mid 80s north to near 90 south. However, the humid airmass will help push heat index values to near or over 100 degrees at times, especially for portions of central and southern GA on Monday and Tuesday. Ware && .AVIATION... (06Z TAFS) Issued at 143 AM EDT Sun Jun 21 2026 VFR conditions ongoing across much of the area to start the period. IFR CIGs and patchy FG likely develop across western and southern areas (CSG and MCN), potentially reaching into the ATL area. These low CIGs would scatter and lift back to VFR conditions by 16Z, with SCT SHRA/TSRA around from 18-00Z as far north as the ATL area, and better chances at CSG and MCN. Winds generally out of the W-SW at 5-8 kts or less through the period. //ATL Confidence...06Z Update... Medium in CIGs this morning and TSRA chances this afternoon. High on other elements.
