What does it take to be a good snow forecaster?

How does the NWS determine the snowfall amount?

  • This snowfall amount is determined by NWS forecasters to be the most likely outcome based on evaluation of data from computer models, satellite, radar, and other observations. This map depicts a reasonable upper-end snowfall amount for the time period shown on the graphic, based on many computer model simulations of possible snowfall totals.

What are probabilistic snowfall products?

  • The purpose of these experimental probabilistic snowfall products is to provide customers and partners a range of snowfall possibilities, in complement to existing NWS deterministic snowfall graphics, to better communicate forecast uncertainties during winter weather events.

What are the odds of snow on the ground?

  • This higher amount is an unlikely scenario, with only a 1 in 10, or 10% chance that more snow will fall, and a 9 in 10, or 90% chance that less snow will fall. This number can help serve as an upper-end scenario for planning purposes.

Forecasting snow requires • knowledge of the numerical models – must resolve which model has best storm track • knowledge of whether the pattern the model is forecasting favors a major snowstorm or a minor one. • an assessment of whether the model is handling the mesoscale structure correctly. • knowledge of the model low-level temperature biases.
