033 FXUS62 KFFC 040128 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 928 PM EDT Thu Apr 3 2025 .UPDATE... Issued at 921 PM EDT Thu Apr 3 2025 No major changes needed to the ongoing forecast for the overnight hours. Made some minor tweaks to the hourly temp and dew grids. Stationary front continues to stretch from the eastern Great Lakes back through the Lower Mississippi River Valley. This front will remain well to the west of the CWA overnight, while high pressure remains situated across the western Atlantic. Temps overnight should range from 15 to 25 degrees above normal for this time of year. && .SHORT TERM... (This evening through Friday) Issued at 303 PM EDT Thu Apr 3 2025 Key Messages: - Near record or record warmth will continue today and tomorrow across the CWA. Highs will be in the mid to upper 80s across all but the mountains. - Afternoon showers and few storms possible, but these will likely be very isolated to mostly NE GA. Forecast: This morning`s 12Z sounding from FFC is sitting right on the 90th percentile for 500mb heights which to the meteorologists in the crowd will likely say a lot about our current conditions. We have a large subtropical ridge sitting over the top of the southeast centered just off the Atlantic coastline of Georgia. This feature is going to remain mostly stationary, getting pumped a bit by a stalled upper level low to the west that is getting pinched by a rossby wave break over the Alaskan panhandle. With a surface high underneath this ridge to our east, surface winds are from the south and pumping in moisture and heat from the Gulf across the area that continues to build. Early morning cloud cover has given way to a cu field that has continued to rise and scatter and let the spring sun angle build the surface temps. Temperatures have risen into the upper 70s and 80s across the CWA. High temps are going to likely approach some local climate site records, but whether or not we actually make it to the records has some uncertainty. The early morning cloud cover delayed the afternoon heating compared to much of the expected model guidance/blends, but we are doing our best to catch up now that mixing is underway. Thinking we may end up just short of current forecast highs, which would likely keep us under most records, but we still have another hour or two of heating to go. Other thing to watch today will be the potential for very isolated storms. Morning sounding showed a pretty stout capping inversion located at approximately 700 mb, representative of the strong ridging overhead. However, surface Ts are managing to approach levels that may allow a few of the stronger convective cells in the boundary layer to take off across the CWA. Southerly winds buffeting into the terrain of NE GA will likely aid this, so best chances of seeing something (and per radar, best returns are already in the area) will be across NE GA. Tonight, temps will dip into the 60s, which is relatively warm for this time of year. Tomorrow looks like much of the same as today in terms of temperatures. Upper level ridge remains in place, but overnight moisture return with nocturnal inversion will allow for the potential for low level cloud cover again. So, whether or not we approach record temperatures again tomorrow will be dependent on morning cloud cover, most likely. Thunderstorm chances will look much the same, with the best chances across NE GA. Lusk && .LONG TERM... (Saturday morning through next Wednesday) Issued at 303 PM EDT Thu Apr 3 2025 Key Messages: - Starts hot. Ends cold. - Some strong to severe weather is possible on Sunday. Forecast: Kicking off the long term we`re looking to break high temperature records. Highs could be pushing 90 degrees in some places on Saturday and even into Sunday. But the game is set to change on Sunday as a cold front pushes through sometime Sunday afternoon. With temps in the upper 80s over mid 60s dewpoints it makes sense that we`re set up for some convective activity. Timing will likely make all the difference in how big a threat this next front is. Some model runs have it pushing through later in the afternoon which will allow more instability to build. It looks like the main area of concern will be along the GA/AL border south of I-20. We`ll keep an eye out on how things shape up and will continue to provide updates over the next few AFDs. I can`t believe I`m saying this, but after the front pushes through we`ll likely see some widespread frost and freezing in the area on Wednesday and into Thursday as reinforcing cold air is pushed out of the north. Temperatures are expected to drop below freezing north of I-85; as a result frost and freeze warnings will likely be needed pending dewpoint and winds speeds. High temperatures will be in the 60s for most of the workweek and will do their best to slowly push back into the low 70s by the time next weekend rolls around. Vaughn && .AVIATION... (00Z TAFS) Issued at 703 PM EDT Thu Apr 3 2025 Cu should slowly diminish after sunset. MVFR clouds likely just before 12Z with a period of bkn IFR possible. Good cu field possible again tomorrow. Winds are going to continue to be due south through much of the period. //ATL Confidence...00Z Update... Med confidence cigs and wind direction. NListemaa && .PRELIMINARY POINT TEMPS/POPS...
