945 FXUS62 KRAH 031850 AFDRAH Area Forecast Discussion National Weather Service Raleigh NC 250 PM EDT Wed Sep 3 2025 .SYNOPSIS... High pressure to our north will extend southward through the area today. A weak cold front will approach from the west tonight and early Thursday. This front will stall out and hold to our northwest through Saturday, allowing warmer air to flow into the region. The front will push into the area Saturday night and Sunday, with cooler high pressure then returning for Sunday night through Tuesday. && .NEAR TERM /THROUGH TONIGHT/... As of 105 PM Wednesday... An upper level trough axis will swing across the MS valley through tomorrow morning. At the surface high pressure generally centered over our region will shift offshore by early Thursday morning. Energy from the mid/upper level short wave are producing areas of showers just west of our CWA this afternoon. With the eastward trend of the shower activity this afternoon, introduced a low end slight chance of showers for the NW portions of Forsyth county for a few hours late this afternoon. While cloud coverage is mainly across the western Piedmont and Mountains, the rest of the area is mostly clear and Sunny. Highs this afternoon will range from low 80s north to mid 80s across the south. Overnight lows will continue to trend warmer generally around 60 degrees with a few cooler spots in the upper 50s. && .SHORT TERM /THURSDAY AND THURSDAY NIGHT/... As of 130 PM Wednesday... As the upper level trough axis swings through the Mid-Atlantic region Thursday, the upper level low remains almost stationary over the upper Great Lakes. At the surface, a frontal boundary inching across the OH and TN valleys will slowly make it towards the Appalachian Mountains before washing out over our region and keeping precip to the NW. Another afternoon/evening of low end slight chance PoPs in the forecast for portions northwestern Piedmont is expected. A few showers and storms could make it into our region but expected to be very isolated. SPC has portions of the NW Piedmont in a Marginal Risk for severe storms, and while storm coverage is expected to be limited an isolated stronger storm or two cant be ruled out. Temperatures on Thursday are expected to be in the low 80s NW to upper 80s across the south. Overnight lows will be in the mid 60s. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... As of 130 PM Wednesday... * Above normal temperatures Friday and Saturday afternoons, before returning to below normal temperatures Sunday after a cold frontal passage. * Isolated to scattered showers and storms possible over the weekend. Friday and Saturday, the region will be in a WAA pre-frontal zone. This will allow temperatures to rise into the upper 80s to low 90s both afternoons, however Saturday should be a degree or two warmer. While Friday should be dry, Saturday will have a return of moisture that may allow for isolated to scattered showers and storms, especially in northern portions of the CWA. The cold front looks to reach the region late Saturday night into Sunday morning, however some guidance shows the cooler air getting stuck in the mountains, making Sundays high temperature forecast a little unclear. Scattered showers and storms will be possible again Sunday afternoon and evening with the cold fropa. Monday through Wednesday, Canadian high pressure will build back in over the region after the passage of the cold front. This along with a wedging regime should allow for below normal temperatures to return. Maximum temperatures each afternoon should be in the 70s, with low 70s in the northwest and upper 70s in the southeast. Minimum temperatures should dip into the mid 50s to the mid 60s. Any rain chances should be low in the east due to coastal moisture. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... As of 248 PM Wednesday... Mountain showers continue to spread east into the Foothills this afternoon. Most high-res guidance fizzles out this precipitation as it moves into our western areas, however still think -RA could show for a few hours this afternoon at KINT/KGSO. As we head into the overnight hours, guidance shows a good signal for fog across the mountains/foothills, with latest high-res guidance creeping those lower visibilities close to KINT/KGSO. While confidence isn`t high that these sites will go sub-VFR tonight, decided to add a tempo group from 8 to 12Z to account for this possibility. Otherwise, sly flow will pick up late tomorrow morning with gusts up to 20 kts possible at all TAF sites. Outlook: Scattered showers and storms will be possible Thursday, Friday, and again on Saturday afternoon/evening. Periods of stratus/fog may be possible each night as well. && .RAH WATCHES/WARNINGS/ADVISORIES... None. && $$ SYNOPSIS...Hartfield NEAR TERM...CA SHORT TERM...CA LONG TERM...Helock AVIATION...Luchetti
