085 FXUS62 KRAH 021741 AFDRAH Area Forecast Discussion National Weather Service Raleigh NC 140 PM EDT Tue Sep 2 2025 .SYNOPSIS... High pressure will dominate through Wednesday. A weak cold front will approach from the west Wednesday night and early Thursday. The front will push into the area Saturday night, with cooler high pressure then returning for Sunday into Monday. && .NEAR TERM /THROUGH TONIGHT/... As of 115 PM Tuesday... Surface high pressure remains over Central NC tonight. Northeast winds of 10mph with occasional guts of 15 to 20 mph this afternoon will become light to calm overnight. Latest visible satellite show a large cumulus field developing across much of the Mid-Atlantic, should not impact temperatures from reaching the upper 70s to low 80s this afternoon. Skies are expected to become clear later this evening through tonight with overnight lows ranging from the low to mid 50s north to mid/upper 50s south. && .SHORT TERM /WEDNESDAY AND WEDNESDAY NIGHT/... As of 125 PM Tuesday... As the surface, high pressure will slowly shift eastward off the US coast Wednesday. Light northeasterly flow will slowly veer to a more south/southeasterly flow by Wednesday night. Expect another dry day with a few cumulus clouds passing over the region with highs a tad warmer in the low to mid 80s. Lows will also be a tad warmer with everywhere expected to be in the low 60s. && .LONG TERM /THURSDAY THROUGH TUESDAY/... As of 115 PM Tuesday... * Briefly hot conditions this weekend before a cold front returns central NC to near normal. * Precipitation chances remain limited through early next week. Surface high pressure initially over the area will gradually disperse through the day and defer to the mass response from the area of low pressure occluding over central Ontario. This will return a period of southerly flow to the area into the weekend and provide gradual warm-up to above normal by Fri. Sat appears to be the warmest day (MaxT upper 80s to low/mid 90s) with the fropa expected sometime between Sat night and Sun. Timing of the next cold frontal passage remains uncertain, ranging from Sat afternoon to late Sun night, and will have a large effect on Sun high temperatures and precipitation chances this weekend. Precip chances remain limited, but may be trending upward a bit for late Thurs afternoon into the evening hours. Most global models have some isolated to scattered measurable rain in the Piedmont from 21z to 03z, the most aggressive of which is the RRFS. The environment is still fighting weak forcing within the initial surface moisture surge. However, if 500-1000 J/kg of MLCAPE can develop deeper convection, 25-35 kts of shear would allow for some loosely organized multicells to produce isolated damaging wind gusts in the northwest Piedmont, including the Triad. The cold frontal passage this weekend may provide a better overlap of frontogenetical forcing and assistance from the sea breeze, but timing is resulting in a low confidence forecast at this time and keeps PoPs 15 to 35%. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... As of 140 PM Tuesday... TAF period: VFR conditions will prevail through this evening, with occasional NELY gusts of 15-18 kts. While KINT and KGSO should remain VFR overnight, model guidance suggests a period of IFR to MVFR restrictions in fog may develop between 07 to 12z across eastern sites(KRWI, KFAY) and possibly KRDU sites. Any fog that does develop will lift and dissipate shortly after daybreak, yielding dry VFR conditions for Wednesday. Outlook: A weakening front will move into the area Thursday afternoon and evening, bringing a chance of scattered showers or storms, mainly at KINT and KGSO. A stronger colder front will arrive from the west late Saturday, with more widespread rain chances all Saturday afternoon into early Sunday across all of central NC. Otherwise, aside from patchy early morning fog or stratus, predominately VFR conditions are expected through the extended period. && .RAH WATCHES/WARNINGS/ADVISORIES...
