Interesting Week Of Weather On Tap For WNC
With snow flurries possible both Tuesday and Wednesday, then the potential for a gulf low to develop into the weekend.. the weather around WNC is about to get very interesting. Many of the major models suggest that a large winter storm could move through the southeast next weekend, causing a multitude of problems. This is not set in stone though, so some caution must be taken when review the following model data. These are simply model depictions and should not be taken as spoken word.
Snow Showers/Flurries Tuesday & Wednesday
Backside moisture will stream through the area Tuesday and into Wednesday bring the chance for snow showers in the higher elevations (above 3500’), and snow flurries in the lower elevations around Asheville. A couple of inches cannot be ruled out in the highest elevations, and a dusting cannot be ruled out north of Asheville.. but this appears to be less impactful compared to the system projected to move in late Friday night.

Gulf Low Develops
On Friday, a system develops over Texas, and begins to move towards the Southeast. This is aided by a strong banana high pressure that moves in tandem with the low. The banana high funnels in the cold air that could potential keep WNC as snow throughout the duration of the event. As you can see below on the GFS precipitation depiction, overrunning moisture begins to stream in late Friday night or early Saturday morning, and falls in the form of snow in many locations.

The European model has been persistent with a similar solution for the past several days. The European Ensemble has also been showing a signal for a large winter storm for the past 2.5 days. This can all change quickly, but a stout high pressure like what is being modeled, is what many expected to occur this winter and can lead to some very impactful storms around WNC. Below you can see the potential snowfall total map produced by the most recent GFS. This is just one model depiction, but other models including the European have been spitting out similar solutions.
