Synoptic Overview:
The upcoming week in Western North Carolina promises a dynamic weather pattern, guided by a series of atmospheric shifts. Currently experiencing light showers, a cold front is expected to usher in drier air late tonight. However, brace for reinforcing cold fronts on Monday and Tuesday nights, each bringing its own nuances to the region’s weather.
Day 1 – Current Conditions and Tonight:
As of now, temperatures range from the mid-60s to lower 70s east of the mountains and foothills, with a cold front pushing through the area. Dry air follows the front, clearing low clouds and setting the stage for a chilly night. Dry high pressure will traverse the area tonight, keeping winds light and preventing fog formation. Lows are expected to dip into the 30s in the mountains and the lower to mid-40s in the foothills.
Day 2 – Monday:
A strong vort max crossing the Southern Appalachians on Monday may bring a brief shot of moisture along the TN/NC border. A few showers are possible, particularly in the higher elevations, but significant rain accumulations are not expected. Expect mostly sunny conditions elsewhere with breezy weather and temperatures about 5-8 degrees above normal.
Days 3-4 – Monday Night through Tuesday Night:
A decent upper shortwave digs into the SE CONUS on Monday, bringing a few rain/snow showers over the mountains. The main forcing passes through Monday afternoon, maintaining mostly rain. Another system moves down from the north on Tuesday night, bringing more rain/snow over the mountains. Some accumulating snow will be possible across the higher elevations. Dry conditions continue in the foothills and northwest piedmont, with temperatures gradually cooling.
Days 5-7 – Wednesday through Sunday:
Following the Tuesday night system, a major cold front is expected to cool temperatures under dry high pressure on Thursday and Friday. The weather remains dry, with temperatures around 5 degrees below normal for lows and near normal for highs. Attention then turns to the weekend, with the potential for a significant synoptic weather system. While models differ on precipitation amounts, both suggest a major front arriving Saturday or Sunday, bringing a mix of rain and possible snow to the region. Right now it is unclear if the systems can merge together and create a major East coast winter storm or if the cold front will chase the moisture away from the Carolinas.
Conclusion:
As we navigate the atmospheric tapestry over Western North Carolina, the upcoming week unfolds with a mix of dry spells, brief showers, and reinforcing cold fronts. Some higher elevation snow is possible early to mid week. Stay weather-ready and tuned to local updates for real-time information as the region experiences these diverse weather patterns.
