Synoptic Overview
The upcoming week in Western North Carolina promises a dynamic atmospheric ballet with multiple players gracing the stage. A cold front passing overnight brings drier air, setting the scene for reinforcing cold fronts late Monday and Tuesday evening. This choreography may permit light rain or snow along the Appalachians on Wednesday morning. Dry high pressure then takes center stage, allowing temperatures to rise through late in the week, only to potentially be upstaged by active weather next weekend.
Today and Tonight
As the morning unfolds, sattelite shows a patch of high clouds quickly moving east across the area. An upper low over Missouri will deepen and move east, bringing a bit of light moisture to the mountains this afternoon. This may result in a brief and small chance of snow possible on the high peaks. Downslope flow east of the mountains will allow for clearing skies and temperatures to climb back to around 60°.Tonight, high pressure briefly moves in, dropping temperatures back into the low and mid 30’s.
Tuesday – Wednesday Night
Multiple shortwaves of energy will dance across the region, steering a cold front through the Carolinas Tuesday. The limited amount of deep moisture will hinder precipitation potential except in the mountains. The second shortwave may bring precipitation after midnight Wednesday morning, starting as rain or a mix before transitioning to snow across the mountains. Ski areas could see some bursts of moderate snow. Mountain soundings do support all snow, mainly in a NW flow pattern. Advisory-level snowfall is possible, particularly across the highest elevations. Quick drying and cooling follow the front on Wednesday, with breezy conditions persisting.
Thursday through Sunday
Thursday marks the last gasp of NW flow snow, giving way to a rapid improvement in conditions across the mountains. A building ridge of high pressure should allow high temperatures to warm into the low and mid-60s by Friday and Saturday. The timing of a robust upper trough on Saturday remains uncertain, with potential for accumulating snow showers again in the mountains. The forecast leans towards a faster progression, for now. However, the details of this climactic act are subject to adjustments as the atmospheric drama unfolds.
In conclusion, Western North Carolina is in for a week of weather theatrics, showcasing the delicate interplay of atmospheric elements. Stay tuned for real-time updates, as the performance may feature surprises and twists in this captivating meteorological ballet.
