Snow chances are gradually increasing for the upcoming weekend across the Western North Carolina Foothills as we continue to watch the likely development of low pressure off the Carolina coast. While there is still uncertainty about how everything will come together, confidence is growing that colder air will already be in place before any precipitation arrives. That means if snow does fall, it could quickly lead to travel impacts due to cold road temperatures.
The overall weather pattern is becoming more supportive of winter weather. A strong arctic system currently positioned over central Canada is forecast to dive south into the central United States late this week. As this system moves east, it will help reinforce cold air across the Southeast, including the Foothills. At the same time, another piece of energy is expected to move out of the southern Plains, while a stream of moisture extends across the southern U.S. Eventually, these features may work together to help develop a storm system near the East Coast.
Cold air will not be the issue with this setup. Temperatures are expected to be cold enough that any precipitation that reaches the Foothills would fall mainly as snow. The bigger question is how much moisture we actually get and how close the developing storm tracks to our area.
There are a few different ways this could play out. In a more impactful scenario, the main arctic system digs farther south and combines with the southern energy. This would allow a stronger storm to develop and move close enough to bring accumulating snow to the Foothills. In another scenario, the systems stay more separate and the coastal storm develops too far offshore, limiting moisture and keeping snowfall light or minimal. A third possibility exists where enough energy lingers overhead to support some snow even if the coastal system stays farther away.
Because temperatures will be cold, even a small amount of snow could cause problems on area roads. An inch or two may not sound like much, but with cold pavement temperatures, travel could quickly become slick and hazardous.
The bottom line is that the trend is moving toward at least some potential for accumulating snow this weekend, but the forecast is still far from locked in. Small changes in the track or timing of these systems will make a big difference in how much snow the Foothills see, if any at all. This forecast will continue to evolve throughout the week, and checking daily updates will be important as details become clearer.
