119 FXUS62 KRAH 071840 RRA AFDRAH Area Forecast Discussion National Weather Service Raleigh NC 141 PM EST Sun Dec 7 2025 .SYNOPSIS... A front will hold to our southeast through the rest of the weekend, as weak high pressure settles over North Carolina and the Mid Atlantic region. An Arctic cold front will move southeastward through the area on Monday, while an upper level disturbance passes overhead. Chilly high pressure will build in from the north Monday night and Tuesday, then move to our southeast, allowing a southwest flow and milder temperatures to return for Wednesday and Thursday. .NEAR TERM /TODAY THROUGH TONIGHT/... As of 110 PM Sunday... * Temperatures remain below normal. * Approaching rain, with potentially a few flakes of snow by morning. Weak high pressure will continue to pass through the mid-Atlantic through the day today ahead of an approaching trough and associated cold front. Areas of dense fog this morning have improved, with most airports reporting 7+ miles of visibility. Low stratus remains, but appear to be dissipating some with daytime heating. Partly to mostly cloudy skies look to remain through the afternoon, with increasing clouds tonight ahead of the frontal passage. Precip chances look to have the best chance of holding off until after sunrise on Monday. However, a brief period of cold, light rain with a few snowflakes mixed in may be possible in the Triad just before sunrise. Temperatures this afternoon look to stay cooler than previously forecast with the increased cloud cover, generally into the 40s, with a few spots staying in the upper 30s. Lows tonight should dip into the upper 20s to low 30s, with much of the region at or below freezing. && .SHORT TERM /MONDAY AND MONDAY NIGHT/... As of 240 AM Sunday... * Chance of precipitation areawide Mon, likely mixing with then changing to a period of all snow before ending, especially across the N and W. * Precip amounts should generally be under a quarter inch liquid equivalent, suggesting that any snow accumulation would be mostly under an inch given the initial rain/snow mix, but stay tuned. Forcing for ascent focused in the mid and upper levels should continue to ramp up early Mon as the aforementioned trough approaches, but the incoming PW values will likely be just near normal and falling further late in the day as the mid-upper levels start to dry out. But forecast soundings show at least a few hours in which the column is saturated or nearly so throughout the mixed phase region aloft down to the surface, occurring in conjunction with peak mid level DPVA from late morning through late afternoon W to E. The incoming Arctic front is expected to push SSE through central NC in the afternoon, so the coldest air may be chasing the better moisture to some degree during the morning hours, particularly if the higher terrain manages to delay the coldest and most dense air for a few hours. But we`re still likely to see an atypical temp trend with surface temps falling in the afternoon, and confidence is increasing that we`ll see at least a couple of hours of predominant light wet snow over all but the far S and SE CWA Mon afternoon as the low levels cool, with accumulations potentially limited by the initial rain/snow mix, the surface temps sitting near or slightly above freezing for much of the day, and the modest PW values. Model agreement is good in showing a thermal pattern supporting patchy light rain chances at onset, followed by good chance to likely pops for a light rain/snow mix, then changing to mostly light snow before ending in the late afternoon or very early evening, with no reasonable chance of any icing or freezing precip. Total accumulation should range from a trace along and N of a line from the Triad to near Goldsboro, ranging to one half to just under one inch near the VA border. Expect highs in the upper 30s to mid 40s early, with readings falling through the 30s in the afternoon. Cold lows Mon night in the mid teens to low 20s will lead to minimum wind chills in the teens in most places overnight into Tue morning. While any lingering precip on the ground will begin to dry out overnight, we`ll be lacking a strong wind to aid in the drying process, and there is a good chance in a flash freeze with areas of black ice developing, which would cause travel concerns late Mon night into early Tue. -GIH && .LONG TERM /TUESDAY THROUGH SUNDAY/... As of 140 PM Sunday... * Continued chilly Tue/Tue night, then moderating Wed/Thu before dropping back well below normal by Sat/Sun. * Precip chances return late Thursday night through Friday night associated with another cold front. After Monday`s cold frontal passage, high pressure will build into the region from the northwest on Tuesday before reaching south of the region by Wednesday. This will allow for temperatures to remain well below normal on Tuesday, but moderate to near normal on Wednesday and Thursday as the high brings in warmer air from the south. A trough and its associated cold front then looks to move through the region late Thursday. With this front, light rain is currently expected to begin late Thursday night and last through Friday. Current model soundings support that a brief period of light snow may be possible on the back end of the precipitation if moisture is able to stick around long enough for the cold air to reach central NC, but ice does not look to be supported. If any snow is to fall, only light amounts currently look possible late Friday night. Details will refined as we get closer to the event. Additionally, a dry reinforcing cold front looks to move through the region Saturday, dropping temperatures well below normal for next weekend. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... As of 1152 AM Sunday... Early morning fog has largely dissipated this morning, with some IFR/LIFR ceilings persisting at RDU/RWI/FAY. They will gradually lift to VFR this afternoon, before another round of IFR cigs and MVFR vsbys return tonight. Big story will be precip potential on Monday with a rain/snow mix forecast at INT/GSO around daybreak, eventually changing to all snow by late morning. Rain/snow mix possible at RDU as well, with a changeover to snow likely holding off until just after the end of the TAF period. FAY is likely to remain all rain through 18Z Monday, although a brief changeover later in the day is possible. IFR or lower ceilings and vsbys expected where snow occurs. Outlook: Conditions will rapidly improve from west to east during the day Monday, with dry weather returning area-wide by Monday night. VFR weather forecast through mid/late week thereafter. && .RAH WATCHES/WARNINGS/ADVISORIES...
