203 FXUS62 KRAH 021750 AFDRAH Area Forecast Discussion National Weather Service Raleigh NC 150 PM EDT Sat Aug 2 2025 .SYNOPSIS... A cold front will settle to our south and hold in place into early next week, as cool Canadian high pressure extends into the region from the north. && .NEAR TERM /TODAY THROUGH TONIGHT/... As of 1140 AM Saturday... * Cooler and drier will continue to filter in from the north A cool surface high will continue to wedge south down the Mid- Atlantic seaboard into the Carolinas, while a stationary front lingers across the Deep South and Gulf Coast. Meanwhile, a developing area of low pressure off the Carolina Coast will slowly move eastward out into the Atlantic. Much of the area will remain canvased in a shroud of low clouds and spotty light rain and drizzle through the morning. However, drier air filtering into the area from the north-northeast will lead to gradual improvement in conditions through the afternoon and evening. The light rain and drizzle will taper off, giving way to mostly dry conditions for the afternoon. Skies will become variably cloudy, with some considerable breaks of afternoon sunshine expected across eastern and central NC, while cloud cover should hold on across the western Piedmont. Highs today ranging from mid to upper 70s/near 80 in the east to lower 70s western Piedmont. Tonight, drier air will continue to spread southward, fair to mostly clear skies. Lows will fall into the lower to mid 60s, with some upper 50s in the typically cooler locations across the northern Piedmont---marking the coolest temperatures since the first week of June. && .SHORT TERM /SUNDAY AND SUNDAY NIGHT/... As of 1200 PM Saturday... * Preview of Fall Central NC will remain under the influence of a cool, dry air sfc ridge, while a coastal low pressure system continues to drift slowly east, moving further offshore. Partly to mostly sunny skies are expected with high temperatures averaging 5 to degrees below normal; ranging from upper 70s to near 80 north to lower/mid 80s south. Additionally, daytime mixing will allow dewpoints to lower into the mid to upper 50s across much of the area, resulting in very comfortable humidity levels. Lows Sunday night will be comparable to tonight, consisting mainly in the lower and mid 60s, with some upper 50s possible in outlying and rural areas across the northern Piedmont and coastal plain. &&. .LONG TERM /MONDAY THROUGH SATURDAY/... As of 1120 AM Saturday... * Long-duration cool weather expected with below normal temperatures through Friday. * Best rain chances come Tuesday night into Thursday. Surface high pressure over the northern Mid-Atlantic will be replaced by another area of Canadian high pressure over the Northeast by Tues and will favor north-northeasterly flow over the region throughout the forecast period. A broad area of low pressure is expected to develop along the stalled boundary over the western Atlantic and further lock in the northerly flow over the area. This will persist the below normal temperatures through the forecast period with gradual modification expected Fri into Sat as the surface high begins to shift further east and Bermuda high pressure begins to influence the region. Precipitation chances will be fairly limited until late Tues into Thurs when broad troughing over the Mississippi Valley subtly sharpens and extends weakly perturbed southwesterly flow over the Southeast and southern Mid-Atlantic. Forecast confidence is low during this time due to high model variability, but a period of above normal precipitation chances appears possible sometime during this period. Instability appears limited and may mostly result in an of stratiform rain with some embedded showers/storms at it progresses through the area. Diurnal showers/storms become more likely Fri and Sat as we lose influence from the surface high to the north. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... As of 150 PM Saturday... The IFR/LIFR cigs from earlier this morning have largely improved to MVFR NE-to-SW across central NC, with patchy VFR decks currently in our northeast, including at RWI. While there are still isolated patches of drizzle, most of these are dwindling or pushing to our S, thus vsbys are mostly VFR across the area. The MVFR clouds will continue to slowly lift and break up to scattered, such that all central NC terminals should be VFR by 21z-23z. While sct-bkn clouds based 4500-7000 ft AGL will persist into Sun, VFR conditions should hold through early Sun afternoon. Surface winds from the NE or ENE will hold generally at 8-12 kts with sporadic gusts to 15-20 kts through 23z, then become light (under 6 kts) through tonight, before again rising to 8-12 kts with a few gusts up to 15-20 kts Sun. Looking beyond 18z Sun, the risk of sub-VFR conditions through Sun night appears low, and we`ll be largely dry. VFR conditions are expected to dominate through Thu, although the chance for showers and storms will gradually increase. -GIH && .RAH WATCHES/WARNINGS/ADVISORIES...
