A coastal low is forecast to track up the coast Tuesday morning, but will track far enough offshore and will be weak enough to bring mostly rain ending as a short period of rain/snow mix Tuesday morning. Temperatures Tuesday morning should remain above freezing and no accumulation of snow is expected.

possible snow tuesday night wednesday
Possible Snow Tuesday Night/ Wednesday
  • A very strong upper level trough of low pressure (disturbance marked by the red line) will track across the state Monday night and early Tuesday morning.
  • This system will provide enough instability to create scattered snow showers if enough moisture is available.
monday night tuesday morning
Monday Night / Tuesday Morning
  • Models differ on the actual track of the disturbance and the amount of snow which may fall Monday night / Tuesday morning.
  • The model forecast shown here does forecast enough moisture available to result in scattered snow showers.
  • The patches of light green over NC represent forecast precipitation which would be snow.
issues and concerns
Issues and Concerns
  • No accumulation is expected with any snow which falls Tuesday morning.
  • Temperatures will be much colder Tuesday night / Wednesday morning in the low to mid 20s. If scattered snow showers do develop accumulations across central NC will be possible by daybreak Wednesday.
  • Current trends suggest any snow showers which develop will occur shortly after sunset in the Triad and spread east across the rest of central NC overnight.
  • Any snow which does fall will be mainly a dry type of snow resulting in a higher liquid to snow ratio. A higher snow ratio would allow for more snow depth which could reach a few inches of snow in some locations if enough moisture is available.
keep up with the forecast
Keep up with the Forecast
  • There is still uncertainty regarding exactly how the two storm systems on Tuesday and Wednesday mornings will shape up.
  • Giving the type of storm systems freezing rain should NOT be an issue and the only concerns facing NC are rain Tuesday and possible snow Monday night into early Tuesday.
  • Please check local NWS forecasts and discussions Through Tuesday in order to stay informed.
