113 FXUS61 KRLX 030841 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 341 AM EST Sat Jan 3 2026 .SYNOPSIS... High pressure provides for a drier weekend, except for a few showers down south today. Turning warmer next week amid multiple systems with the potential for rain. && .NEAR TERM /THROUGH TONIGHT/... As of 155 AM Saturday... Low level moisture continues to manifest as low clouds and patchy fog in and just west of the mountains early this morning. High clouds associated with a wave of low pressure passing south of the area may lower and thicken enough to eradicate the lower clouds and fog before dawn. The system itself could produce enough mid-level moisture and lift for light precipitation across southeast portions of the area today. While the elevated moist layer is cold enough to support snow, the low level warm nose, albeit dry, may be warm enough to melt the crystalline hydrometeors, which could in turn freeze with surface temperatures below freezing early this morning. Model QPF is minimal to non-existant early this morning, and temperatures gradually rise above freezing late this morning into this afternoon while the warm nose aloft collapses. While confidence in measurable precipitation and even precipitation type is too low to issue any Winter Weather Advisories, special weather statements will be issued if a minimal threat is able to materialize. Any precipitation will thus trend more toward either rain or snow by this afternoon, when some model output does show a few hundredths of an inch of precipitation, mainly in and near the mountains. It is not out of the question spotty light precipitation persists into tonight into in and near the the mountains, as a negatively tilted shortwave trough crosses amid northwest mid/upper-level flow, but for now, central guidance depicts a dry forecast after this evening. Otherwise, high pressure building in from the northwest tonight will bring clearing and nearly calm conditions, which will favor radiational cooling. As a result, lows will be below normal, with teens north and most any sheltered valley, and otherwise low 20s south. There is some model suggestion of stratus and fog forming over the upper Ohio Valley overnight tonight sneaking down into the middle Ohio Valley early Sunday morning. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... As of 340 AM Saturday... High pressure provides a short, dry, quiet interlude to start the first full week of 2026. One high crosses Sunday and Sunday night. A warm front then scoots north of the area Monday morning. With no real discernible cold front associated with the system, just a weak bubble high builds into the middle and upper Ohio Valley in its wake Monday afternoon into Monday night, and then flattens overnight as low level south to southwest flow takes hold beneath mid/upper-level zonal flow. The high will provide sunshine Sunday once any middle Ohio Valley lows clouds and fog are gone. High and mid cloud spilling southeast from the warm front will overspread the area Sunday night, these clouds giving way to some sunshine on Monday. High clouds increase again Monday night, with low clouds following close behind in the low level south to southwest flow toward dawn Tuesday. Below normal temperatures Sunday and Sunday night give way to above normal temperatures Monday and Monday night, as high pressure gives way to south to southwest flow, interrupted only for a time Monday afternoon and night over portions of the middle Ohio Valley by the weak bubble high. && .LONG TERM /TUESDAY THROUGH FRIDAY/... As of 340 AM Saturday... Increasingly moist and mild south to southwest low level flow dominates through the balance of th first full work week of 2026, as mid/upper-level zonal flow gives way to ridging that builds ands then scoots east across the area. One system makes inroads into the forecast area with some light rain showers from some point Tuesday through Tuesday night. Not much stronger than its Monday morning predecessor, it has a weak if not barely discernible cold front associated with it, and another weak bubble high crosses the area in its wake on Wednesday. This provides another brief dry interlude much of Wednesday into Wednesday night. Additional short wave troughs rotating about the base of a long wave trough out west and then ejecting out of it make increasing inroads into the area Wednesday night through Friday. With the persistent, increasingly moist south to southwest flow across the area, this results in rounds of rain or rain showers with increasing coverage and intensity, becoming moderate to perhaps heavy. This period will need to be monitored for the potential of developing hydro issues. The long wave gets close enough to drive a cold front through the area late Friday or Friday night into Saturday, with its own round of showers. The bubble highs provide some radiational cooling Monday and Wednesday nights. Otherwise, central guidance evinces well-above normal temperatures through the latter portion of the next work week, especially on Thursday and Friday. A distant early first glance suggests only modest cooling, at least initially, behind the Pacific cold front heading into next weekend. && .AVIATION /07Z SATURDAY THROUGH WEDNESDAY/... As of 155 AM Saturday... A high thin overcast and light low-level flow has allowed valley fog to form north, while low level moisture and a light north flow has resulted in LIFR stratus and fog at BKW. IFR to MVFR stratus/stratocumulus was also present elsewhere along and just west of the mountains. These conditions may persist for several predawn hours, before high clouds lower and thicken enough for the fog to thin out and the stratus/stratocu to break up. A wave of low pressure passing south of the area today will have little effect other than to provide enough lowering and thickening clouds to eradicate the stratus and fog early this morning. The system will provide a cloud deck as low as 6 kft today, which may then lower to MVFR in and just west of the mountains late today, before scattering out late tonight. Light north to northeast to variable surface flow today will become Light north to northwest to variable tonight. Light to moderate northwest flow aloft today will become light northwest this afternoon. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z SUNDAY... FORECAST CONFIDENCE: Medium to high. ALTERNATE SCENARIOS: Timing of return to VFR early this morning, and of a period of MVFR stratocu late today into tonight, may vary from the forecast,.
