960 FXUS62 KRAH 091821 AFDRAHArea Forecast Discussion National Weather Service Raleigh NC 220 PM EDT Tue Sep 9 2025
.SYNOPSIS... High pressure centered over the Northeast will extend southwest into the Mid-Atlantic and the Carolinas through much of the work week. Weak disturbances will travel northeast near and along a lingering frontal zone near the coast on Tuesday through Thursday. &&
.NEAR TERM /THROUGH TONIGHT/... As of 220 PM Tuesday...
* Stratocumulus will continue to invade central NC from the east. * Some isolated patches of light rain and drizzle is possible after midnight across the northern and central Coast Plain.
High pressure centered over the northeast U.S. will continue to extend southwest into the Mid-Atlantic and Carolinas through tonight. A cool airmass is in place across the region with todays highs ranging between 4 and 10 degrees below average. The cool airmass will be maintained by a cool and moist low-lelve moist northeast flow into our region. Visible satellite imagery shows a large region of strato-cumulus clouds with bases of 2-3kft across eastern NC an the Coastal Plain that is expanding and pushing west into the Foothills and the Sandhills this afternoon.
These clouds will continue to push east across most of central NC this evening although the clouds will be slow to move into the Yadkin Valley and Triad area this evening. A broad surface low is beginning to develop off the Carolina Coast this afternoon and as it organizes it will help drive additional moisture into the region and back the surface flow to more northerly. There are a few light radar returns organizing near the Outer Banks and there is some potential these scattered showers and other developing showers could approach the northern Coastal Plain after midnight with some patchy light rain. In addition, as the stratus lowers and thickens overnight, some areas of mist and drizzle could also develop across northeast and eastern areas. Low temperatures should be moderated by the clouds cover and range fro the mid 50s in the Yadkin Valley and Triad to around 60 in the Triangle to the lower 60s in the Coastal Plain. -Blaes &&
.SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/... As of 100 PM Tuesday...
* Continued below normal temperatures * Small chance of light rain or even some mist across northeastern areas.
North-northeasterly flow will continue into Wednesday with low pressure offshore, and considering the amount of cloud cover present over eastern counties today, it is likely the clouds will persist tomorrow as well. Meanwhile, skies are likely to be partly to mostly sunny in the Triad. The NAM is the most aggressive model for precipitation, bringing rain as far southwest as Raleigh. Think that this is a bit aggressive, but have brought a slight chance of showers as far southwest as Wake County. With the cloud cover, there should be a modest gradient in high temperatures - it`s possible an isolated location in the northeast may not make it to 70 degrees tomorrow, while the southwest should reach 80 degrees. Lows will range from the mid 50s to the low 60s. &&
.LONG TERM /THURSDAY THROUGH TUESDAY/... As of 115 PM Tuesday...
* Mainly dry weather with slightly below-normal temperatures moderating to near normal.
High pressure will be centered over West Virginia on Thursday morning, remaining nearly stationary through the end of the week before dissipating over the weekend. Meanwhile, another wave of low pressure will form off the Florida coast along the front that has been off the Atlantic coastline. As the low drifts northeast, models are hinting that precipitation could make it far enough west on Saturday afternoon to brush southern Sampson County with an isolated thunderstorm. This is the only time period in the extended forecast with a chance of rain. As that low moves farther offshore, another low will develop over the Northern Plains and begin to edge to the southeast, but any rain with this system should remain west of central North Carolina through Tuesday.
Highs will remain a couple degrees below normal Thursday through Saturday (mid 70s to low 80s) before rising to near normal values on Sunday with a brief rise above normal temperatures on Monday. Similarly, lows will range from the mid 50s to the mid 60s through the period.

.AVIATION /17Z TUESDAY THROUGH SATURDAY/... As of 135 PM Tuesday...
Fair weather with VFR conditions across much of central NC early this afternoon will give way to increasing moisture and low cloudiness from the east during the afternoon and overnight. A band of high clouds will be undercut by invading MVFR stratus and stratocumulus clouds with CIGS between 2-3kft that reached the KRWI terminal this past hour. The westward push is a little uncertain and the timing is tricky but MVFR stratus is expected to reach the KFAY terminal between 19Z and 22Z and the KRDU terminal between 21Z and 23Z. CIGS will lower overnight and a period of IFR CIGS is expected at KRWI between 09Z and 15Z with CIGS approaching IFR at KFAY and KRDU around daybreak Wednesday. It`s unclear how far west the low stratus will make it but feel confident enough at KGSO that marginal MVFR CIGS will be in the area overnight. Overcast skies will persist with CIGS slowly lifting on Wednesday.
North to northeast winds at 6 to 10 kts with gusts of 15 to 20 kts this afternoon will relax tonight with north winds at 5 to 10 kts overnight. North winds at 7 to 10kts are expected on Wednesday with some gusts to around 16kts across eastern locations.
Outlook: There is a good chance of MVFR and possibly IFR stratus impacting eastern locations istrengthens ncluding KRWI and KFAY (and probably KRDU) at times on Wednesday into Thursday. Fair weather is expected across western locations including KINT and KGSO. Fair weather and VFR conditions are largely expected for Friday and Saturday. -Blaes &&
