Potential significant winter storm late Tuesday through Wednesday.
A rain/snow mix could begin late Tuesday before quickly changing to all snow and continuing through the night into Wednesday. The snow may mix with and potentially change to light sleet and freezing rain, ]near the end of the potential precip. The amount of precip associated with this type of classic southern winter storm could be significant. One model is weaker with the system and produces less snow than some of the other models, but it is an outlier and as of now is being disregarded by the National Weather Service Model diagnostic team. This same team is essentially going with a blend between the medium and high impacts shown by the models (But not the highest impact North American Model which gives almost all of North Carolina 13 inches of snow!). Models show anywhere from 4 to 13 inches at this time. It's still too early to officially predict potential snowfall amounts.
Potential impacts:
- Snow potentially mixing with and transitioning to sleet then freezing drizzle.
- Significant accumulations of snow possible, well above warning criteria...Ice accumulation appears minimal at this time for RDU, but could change if the surface low trends stronger and warmer. In this scenario we could get a major ice storm, but it's not predicted by the models at this time.
- High uncertainty exists on amounts and timing of start time and any potential changeover.
