Sunday Update: 7 Day Snow Probabilities

Over the next seven days, the Western Carolinas will certainly be unsettled, with multiple cold-air damming events and storm systems overrunning the shallow cold air. What you’re seeing here in this blog is a look at the overall odds of seeing at least 1 inch of snow at some point over the next seven days, based on terrain-weighted ensemble guidance and how the pattern is evolving.

Also important:
👉 This outlook is for SNOW ONLY.
We are not addressing ice, freezing rain, or sleet with these probabilities.

The Big Pattern Setup

The overall weather pattern going into the coming week supports multiple chances of cold air damming and weak disturbances, rather than a single dominant, high-impact winter storm. The upper-level flow stays active, and cold air remains close enough that minor systems can take advantage of elevation and terrain when moisture lines up just right.

While cold air is available at times, surface temperatures at lower elevations routinely climb above freezing during the daytime. That limits the ice threat and keeps snow mostly confined to higher-elevation zones when precipitation overlaps with colder air.

So the takeaway:
✅ Multiple weak windows for snow
❌ No locked-in big snowstorm

7-Day Snow Probabilities – High Terrain Focus

These continue to be the zones with the most meaningful cumulative chance of seeing at least 1 inch of snow at some point over the next week:

• NW Polk County (Saluda / higher peaks): 26%
• NW Rutherford County (South Mountains / Sunshine–Golden Valley): 26%
• NW McDowell County (Little Switzerland / Parkway ridge tops): 28%
• NW Burke County (Jonas Ridge / Linville Gorge rim): 22%
• NW Caldwell County (Globe / Edgemont / near Blowing Rock): 27%
• Greater / Lower-Elevation Portions
• Greater Burke County (Morganton, Icard, Drexel, Valdese areas):
  7%
  Most precipitation events stay cold rain; brief flakes are possible at times.
• Greater McDowell County (Marion, Old Fort, lower Catawba basin):
  10%
  A little higher than Burke due to proximity to the Blue Ridge escarpment, but still mainly rain.
• Greater Polk County (Columbus, Tryon Valley):
  8%
  Warm downslope influence limits snow potential outside the peaks.
• Greater Rutherford County (Forest City, Rutherfordton, Spindale):
  9%
  Cold rain dominates; snow chance increases only near the South Mountains.
• Greater Caldwell County (Lenoir, Hudson, Granite Falls):
  11%
  Slightly higher due to colder air drainage from the Blue Ridge.

These numbers are driven almost entirely by elevation, cold-air persistence, and upslope enhancement, not by any single storm.

Looking at broader countywide odds:

• Wilkes County: 38% – Highest in the broader neighborhood thanks to Brushy Mountain and Blue Ridge proximity.
• Alexander County: 23%
• Catawba County: 17%
• Cleveland County: 12%
• Lincoln County: 15%

These numbers reflect isolated opportunities, not guaranteed snow. Most of these counties will see cold rain as the primary precipitation type, with only a few windows where snow could briefly mix in — and even fewer where it could accumulate.

What This Means for You

• Higher elevations: A few separate chances for light snow over the next week. Not all at once. Not guaranteed. But the odds are non-zero.
• Foothill valleys & Piedmont: Mostly cold rain events with occasional flakes mixing in at times.

Bottom Line

This is a pattern-driven seven-day outlook, not a storm-specific forecast. We’re watching several small opportunities stack up over the next seven days rather than one big headline system. Terrain will decide who sneaks a dusting and who stays wet.

As always, if one of these windows sharpens into something more organized, we’ll shift from probabilities into impacts and timing. Until then, this is simply the odds board for the week ahead.

More updates coming as the pattern evolves.
