NC Winter Weather Climatology

East-central North Carolina Winter Storm Daily Climatological Probability (Jan 1948-Apr 2021) (smoothed w/ a 15-day running mean). Snow events are defined when at least one observation in non-mountain NCEI climate division areas produces: "Minor" (light gray) at least 1" of snow or Trace of glaze, "Major" (light blue) > 4" of snow or at least 0.25" of glaze, "Extreme" (medium blue) > 8" of snow or at least 0.50" of glaze, "Historic" (deep blue), > 12" of snow or at least 1" of glaze. 
​
**Notice the climatological peak of more intense winter storms is later in the winter season than "minor" events**
