994 FXUS62 KRAH 120653 AFDRAH Area Forecast Discussion National Weather Service Raleigh NC 252 AM EDT Sat Sep 12 2026 .WHAT HAS CHANGED... * Reduced POP for Sunday, raised MaxT Sunday. && .KEY MESSAGES... As of 252 PM Friday... 1) Very warm and humid today, with scattered, mainly PM showers/thunderstorms. Last shot at significant rain through the week. 2) Sunday is trending drier, a bit hotter. Dry with temperatures closer to seasonable values much of next week. && .DISCUSSION... As of 252 AM Saturday... 1) Very warm and humid today, with scattered, mainly PM showers/thunderstorms. Last chance of significant rain for a while! The upper level short wave trough will move from the Tennessee Valley east across the Appalachians and over our region through tonight. The base of the trough will move east of the area Sunday morning. At the surface, a weak cold front (likely consisting of old convective boundaries) was located from west to east, generally along the US-64 corridor from just south of the Triad to the southern part of the Triangle areas. PW`s were analyzed at 1.75 in the western Piedmont to 2+ inches in the NE Coastal Plain. Dew points and surface temperatures were generally in the lower to mid 70s. Earlier lingering showers have all dissipated, with plenty of mid and high clouds around. There were areas of low stratus developing. Some earlier 00z/CAMS were forecasting some showers/storms this morning. It appears they were tied to old MCV`s and disturbances left over from Friday`s storms upstream. However, with the activity now all but gone, the latest CAMS suggest that it will be mostly low stratus and some fog through 13z or so that will prevail. There is little indicating of any additional showers through mid-morning. However, as the stratus breaks we are expecting fairly aggressive heating today into the lower to mid 80s by noon. As the short wave aloft approaches, expect areas of showers and thunderstorms to develop, especially after noon. The higher POP should be between 200 PM and 900 PM. QPF continues to show a lot of variability, but averages around 0.5 in Piedmont. Locally heavy rain is expected to affect some areas, but just as many will not see any rainfall. There should still be scattered storms this evening, even possibly linger into the night in the east. 2) Sunday trending drier, a bit hotter. Mainly dry with temps closer to seasonable values much of next week. With the base of the short wave trough expected to pass east toward the coast before heating Sunday and the surface front to not be far behind, it appears Sunday will bring drier weather and hotter temperatures than today. Readings should reach the upper 80s to around 90. In addition, the showers are expected to be along the coast for the most part. Most of next week will be dry and cooler thanks to an upper ridge that will be positioned to our west much of the time, with surface high pressure to our north and northeast. This will result in a low level NE flow and highs in the 80s. Lows should dip into the 60s for the most part. && .AVIATION /06Z SATURDAY THROUGH WEDNESDAY/... As of 142 AM Saturday... VFR will largely prevail across central NC trough 06z-09z, with low stratus expected to develop over central NC. All terminals likely to experience IFR conditions. A period of LIFR is even possible around daybreak, along with patchy MVFR/IFR visibilities. VFR will return to most areas by midday on Saturday, but MVFR may linger into early afternoon around the Triad. Showers and storms are then expected to develop in the afternoon across the region, and they should be more widespread compared to today. Brief gusty winds and sub-VFR conditions will be possible with any storms. Outlook: Shower and thunderstorm chances will continue through this evening as a cold front makes its way through central NC. Low stratus and/or fog may develop and cause sub-VFR restrictions again on Sunday and Monday mornings as well. && .RAH WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Badgett AVIATION...Badgett/Danco
