074 FXUS62 KFFC 052344 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 644 PM EST Wed Feb 5 2025 ...New 00Z Aviation Discussion... .SHORT TERM... (This afternoon through Thursday) Issued at 155 PM EST Wed Feb 5 2025 Mid level ridging over the Caribbean and broad zonal flow over the Conus appear to be the main players in our weather for the foreseeable future well into the extended amidst perturbations in the flow. For today, very weak CAD ever so slightly leaking into NE GA. Showers and rainfall held off long enough to allow daytime heating to warm much of the region up to near 70. Had the showers arrived a little sooner, would have expected the CAD to begin to feedback given the 40s and 50s dewpoints across the area and bust high temps today. Clouds kept the area from reaching the upper 70s which was forecast last weekend, but we still attained a formidable lower 70s. Subtle shortwave passes well to the north of the region tonight, but close enough to spark an area of rain/rain shield to develop and move across mainly northern GA, north of I20. Frontal boundary approaches the region during the day Thursday but doesn`t quite make it by Friday AM beneath the zonal flow aloft. End result is continued increased chances for showers across the north Thursday into Friday. Thunder chances, albeit low, appear better during the afternoon on Thu across N GA. HREF probs yielding 50pct chances of at least 100 J/kg northern GA (north of 20)...but less than 10pct probs of at least 300 J/Kg. && .LONG TERM... (Friday morning through next Tuesday) Issued at 155 PM EST Wed Feb 5 2025 Unseasonably warm conditions will prevail through at least this weekend despite increasing moisture and chances for precipitation. There`s really not much change in the overall upr lvl pattern in the next 5-7 days; but by the middle of next week, medium-range models indicate the Polar jet finally showing signs of buckling over the western CONUS, thus shifting the anomalously warm upr high (that`s extended from Texas to the Southeast region) off the Atlantic coast. A remnant boundary draped across the area Friday will maintain at least "scattered" rain showers. This boundary quickly lifts northeast late Friday into Saturday but another system traversing the Upper Midwest/Great Lakes will send a weak front across north GA with potentially a more organized chance for additional rainfall. As the pattern shifts to a more southwest flow (aloft) ahead of a digging longwave trough out West, deeper moisture and energy will overspread the SE region leading to an increased risk of heavier rainfall, isolated storms and potentially localized flooding. Temperatures will be 15-20F deg above normal thru Sunday but then start to cool with more clouds and slight dip in the upr lvl heights. DJN.83 && .AVIATION... (00Z TAFS) Issued at 635 PM EST Wed Feb 5 2025 Current VFR cigs trend lower overnight. Initial patchy MVFR is possible in iso/sct -SHRA, but prevailing MVFR cigs become more likely by 06Z at ATL sites and AHN, at which time -SHRA coverage diminishes. IFR cigs are likely by 08-09Z at ATL/AHN sites and persist through 15-17Z before lifting toward MVFR. MVFR will be mostly persistent through afternoon with some scattering by around 00Z. Winds shift to SSE by 01Z with SE winds at 3-5 kts through 12Z before direction shifts back SW. SW winds prevail at 06-10 kts on Thursday. //ATL Confidence...00Z Update... Medium confidence.
