306 FXUS62 KFFC 140516 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 116 AM EDT Sun Jul 14 2024 ...New 06Z Aviation Discussion... .SHORT TERM... (This afternoon through Sunday) Issued at 245 PM EDT Sat Jul 13 2024 Strong Bermuda High remains in place over the Atlantic, to the east- northeast of the forecast area. A weak, poorly-defined tropical low off the Georgia coast continues to bring Atlantic moisture into the Carolinas and eastern Georgia, where it is gradually spreading westward into the forecast area. The rest of the weekend is expected to be defined be a continued warming trend and light, variable winds. Aside from the higher elevations in far north Georgia, highs this afternoon will range from the mid 90s in north Georgia to the upper 90s in central Georgia. With dewpoints remaining in the 60s, heat index values are expected to remain below Heat Advisory thresholds through the period, peaking at around 100. Isolated showers and thunderstorms are expected in portions of far north and east Georgia this afternoon. Low temperatures on Sunday morning will be in the 60s in far northeast Georgia, and low 70s across the rest of the forecast area. Highs will be a couple of degrees warmer across the area on Sunday in the upper 90s across the majority of the forecast area and up to 100 in portions of central Georgia in the peak heating hours. As moisture continues to spread slowly westward, chances for isolated to scattered thunderstorms on Sunday afternoon will have slightly higher coverage than today. Heat index values on Sunday afternoon will range from 98-103 degrees on Sunday afternoon, although will need to be monitored in case an advisory is needed. King && .LONG TERM... (Monday morning through next Friday) Issued at 245 PM EDT Sat Jul 13 2024 Hot temps continue into the long term. Will also see increased rain chances Tues across central GA then Wed through Fri everywhere. The long term picks up on Monday with temps in the upper 90s to 100 across most of Georgia. There could be a few areas where Heat indices could exceed 105 in parts of eastern Georgia; we`ll continue monitoring through the weekend with regards of issuing heat related products. Overnight lows will be in the mid to upper 70s going into Tuesday. Tuesday will mark the beginning of a transition period for most of the area. Temps are expected to remain in the upper 90s but a trough in weak zonal flow will enter the south east and get a bit hung up over the gulf coast. Showers in thunderstorms will be possible for the southern portion of the CWA on Tuesday afternoon, and remain the lifting mechanism for afternoon storms for the rest of the forecast period. With the increased precip chances Wed through Fri will see temps decrease into the upper 80s to lower 90s by Thu/Fri. Drought conditions may get some relief as we head into this rainy period. Precipitable waters will range from the 1.5 to 2.5 inch range Wed through Fri so depending on where the strongest storms set up we could see some decent amounts. 7 day QPF totals are in the 1 to 2 inch range and would not be surprised to see some isolated higher totals especially across central GA. Widespread severe weather is not expected, but a few afternoon storms could be strong with gusty winds, periods of heavy rain, and frequent lightning. Vaughn/01 && .AVIATION...
