672 FXUS62 KRAH 110032 AFDRAH Area Forecast Discussion National Weather Service Raleigh NC 832 PM EDT Fri Oct 10 2025 .SYNOPSIS... Canadian high pressure will shift offshore tonight and Saturday. Low pressure developing near the SE coast will move north along the NC coast over the weekend. && .NEAR TERM /THROUGH TONIGHT/... As of 300 PM Friday... *Rain to spread into the Southeastern NC late tonight Canadian high pressure extending south into the Carolinas will gradually weaken ahead of the developing coastal low over Florida. Cloud cover will continue to thicken and lower this evening and tonight, with rain chances spreading inland into the southern and central Coastal Plain counties during the predawn hours as strengthening moist easterly Atlantic maritime feed expands north into the area. NELY gustiness of 15-20 mph will subside this evening before re- developing late tonight as the pressure gradient tightens once again. Not as cool overnight, with lows ranging from lower 50s NW to lower 60s SE. && .SHORT TERM /SATURDAY AND SATURDAY NIGHT/... As of 300 PM Friday... *Rain and breezy conditions spreading inland through Saturday night A deepening upper level trough and associated closed low pivoting over the Southeast will help lift the coastal low near Florida northward along the NC coast by Saturday night and Sunday morning. Strengthening easterly Atlantic flow will transport deep moisture (PWs 1.5-1.75 inches)inland through the period. Rain will gradually spread from the southern coastal plain into the Sandhills and central Piedmont during the afternoon, expanding further inland into the western Piedmont during the evening and overnight hours as frontogenetical forcing within the associated comma-head shifts westward. The heaviest rainfall amounts and greatest flooding will remain focused along the NC coast, where higher rainfall amounts/rates are expected. Across central NC, rainfall will generally be light to briefly moderate, with a sharp east-to-west gradient in amounts- --ranging from 1-1.5" east, 0.50-1.0" central, and 0.25-0.50" across the western Piedmont. Expect frequent NELY gusts of 20 to 25 mph, with peak gusts potentially reaching 30 to 35 mph within the better rain bands across eastern/coastal NC. Widespread low clouds and westward expanding rain coverage will hold afternoon highs to around 65 to 70 mph, with minimal nocturnal cooling. Lows will range from the upper 50s to lower 60s. && .LONG TERM /SUNDAY THROUGH FRIDAY/... As of 230 PM Friday... * A coastal low will linger over the region Sunday and potentially into Monday, bringing continued rain and gusty conditions. * Continued warming trend until late next week. Model guidance is showing the coastal low, or potentially a pair of coastal lows, making the closest approach to the Outer Banks Sunday into Monday. Although there is still some uncertainty, light rain is still expected to continue throughout the day and overnight on Sunday. Some pockets of heavier rain could still be possible on Sunday depending on the location and strength of the low. Models differ in how fast the low will exit the region, leaving some uncertainty with how long into Monday light rain will continue, with the best chance for continued rain in the northeast. Overall, less than 0.5 inches of additional rain is expected on Sunday and Monday, with Saturday having the best potential for the heaviest rainfall with the system. Sunday into Monday morning also has the potential to be gusty as the system makes its closest approach to central NC, with gusts around 25 to 30 mph possible. After the coastal low moves further northeast out of the region, ridging should start to spread eastward. This will allow temperatures to rise to slightly above normal by mid-week. High temperatures are expected to be in the mid 60s to low 70s on Sunday and increase to the 70s by Wednesday before another slight cool down is possible Thursday and Friday. Lows should be in the 50s to low 60s each night until cooling to the 40s on Thursday night. && .AVIATION /00Z SATURDAY THROUGH THURSDAY/... As of 825 PM Friday... 24-hour TAF period: VFR will prevail across central NC through this evening as a deck of high cloud ceilings and scattered to broken cloudiness around 4-7 kft continues to spill into central NC in advance of a developing coastal low currently centered over FL. As this low deepens and moves NNE, ceilings will lower overnight, with MVFR expected as early as 09z at the eastern TAF sites (RDU, FAY and RWI). Isolated light rain will also be possible by this time in the far south and east (including FAY and RWI). Steadier light rain will then spread into southern and eastern areas (including RDU, FAY and RWI) during the late morning and early afternoon, which is also when some MVFR visibilities and IFR ceilings will begin to be possible. However, model guidance differs substantially on timing of IFR ceilings, so confidence is low. Farther west at INT and GSO, while it should stay dry through the TAF period, guidance is showing potential for periods of MVFR stratus after 12z Saturday, best chance at GSO. Wind gusts have largely subsided across the region, but NE winds around 5-10 kts will continue overnight, before increasing again by late morning and gusting up to 15-25 kts at times (highest SE). Beyond 00Z Sunday: A steadier shield of moderate will spread into all of central NC Saturday evening and into the overnight period. As such, expect periods of LIFR conditions especially at KFAY/KRWI where heaviest rain appears possible. The low will slowly migrate northward Sunday into Monday. As such, expect periods of rain and sub-VFR conditions to persist through Monday morning, with sub-VFR ceilings perhaps lingering into Monday night in the east. Additionally, periods of LLWS may be possible Saturday night at KFAY/KRWI. Strong nely gusts of 25-30 kts may redevelop Sunday morning, especially at KFAY, depending on the eventual track of the low. Expect high pressure and VFR conditions to return from Tuesday through the remainder of the extended period. && .RAH WATCHES/WARNINGS/ADVISORIES...
