Developmental Probabilistic Snow Accumulation Forecast (DIA)
National Weather Service Denver/Boulder, Colorado
2058 MST Thursday, February 20, 2025

--------------------------------------------------------------------------------
This developmental product contains the probabilities (%) that the given snow
amounts (inches) will occur at Denver International Airport during the respective
3 hour or 12 hour periods.  The probabilities indicate the amount of snow that
is expected to accumulate on runways and other concrete surfaces at DIA.
[T (trace) means more than zero.]
--------------------------------------------------------------------------------

Discussion (20/23-21/23 MST): Snow will continue through the morning across the
terminals.  The latest model guidance has continued to trend the heaviest snow
towards the southern Denver metro and DIA will be on the far northern edge of
accumulating snowfall. The forecast still calls for 1-3" of snow with a very
small potential for up to 6" .
