Area forecast discussion, May 25, 3:49 PM EDT, 28 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 349 PM EDT Fri May 25 2018 .SHORT TERM /Tonight through Saturday Night/... With Subtropical Storm Alberto off the Yucatan Peninsula and high pressure off the southeast coast, this has allowed abnormally high moisture flux to increase across the southeast. Therefore we have widespread showers and isolated thunderstorms continuing across east central GA this afternoon. This activity will continue through early evening, eventually diminishing while it lifts north with some precipitation (likely in the form of showers) moving into the metro. The coverage will be limited, but a better chance for the metro to see precipitation, especially between 20Z and 04Z. Activity should diminish later tonight. Patchy fog is possible during the morning hours. With the mid-level ridge trying to build in a bit across SE GA, this will likely limit the coverage of showers/thunderstorms tomorrow. However, looking aloft, best vorticity will be across north GA. Therefore, we expect this area to be the axis by which we see better coverage of showers/thunderstorms, likely later afternoon/evening Saturday. This activity should diminish after midnight Sunday. The main impact with any showers/thunderstorms will be heavy rain. Expect high rainfall rates given the high PWATs and efficient saturation in the atmospheric column. Minor flooding could occur quickly with these heavy downpours. Precipitation totals through the short-term will be around a half an inch areawide with locally higher amounts possible associated with those heavier showers/storms. Temperatures will be slightly below normal. 26 .LONG TERM /Sunday through Friday/... The main concerns through the long term period will centered around precipitation from what is now Subtropical Storm Alberto, as of the 11 AM EST update from NHC. As of the most recent forecast package, NHC has Alberto reaching land sometime on Monday near the AL/MS border. Models start to diverge after reaching land, but the overall trend in the models is a generally east track towards our area. The GFS brings Alberto through our northwest corner late Wednesday, while ECMWF keeps Alberto further north and west of our area completely. Regardless of the model differences and the exact track/intensity of Subtropical Storm Alberto, heavy rain will be a continued threat in our area through the long term period as PWATs rise to 1.5 to 2+ inches. For our area, Alberto will bring heavy rainfall and the potential for flooding. Although winds should not be a major issue with Alberto, with already wet soils it will be relatively easy for trees to fall. Current QPF associated with Alberto is about 3-6 inches with locally higher amounts possible, especially in northeast GA and east central GA. Flash flooding will also become a problem as well as river flooding. With the above-normal rainfall that most areas have seen over the past few days, soils are already saturated and additional precip would be expected to cause problems. Make sure to be aware of any forecast changes/watches/warnings, as well as updates from NHC, as there is still uncertainty within the track of Alberto. The need for any flood-related watches will continue to be monitored. Decided to go with a blend for precip for most of the long term as models diverge shortly after Alberto reaches land. Regardless, chances for showers and thunderstorms exist daily and any day could see a strong thunderstorm. High temps through the long term are generally in the upper 70s and 80s, with low temps in the 60s and 70s. Reaves && .AVIATION... 18Z Update... Widespread showers and isolated thunderstorms have developed across our SE tier, impacting MCN and AHN through the rest of the afternoon. Mixed bag of MVFR/VFR cigs with reduced vsbys associated with any heavy showers. We may see this activity expand further north and west over timing, impacting the metro TAF sites and CSG later this afternoon/evening. Activity should diminish after midnight with redevelopment of showers/thunderstorms by late morning/early afternoon on Saturday. Cigs will come down to MVFR/IFR later tonight through mid-morning, lifting by late morning. Patchy fog is possible. Looks like skies try to clear a bit tomorrow afternoon with better coverage of precipitation further north late tomorrow afternoon/evening. Winds will be out of the SE this afternoon, becoming SSE. Models show winds briefly becoming SSW in the mid- morning, but confidence is low on this. //ATL Confidence...18Z Update... Medium confidence all elements. 26 && .PRELIMINARY POINT TEMPS/POPS...
