Developmental Probabilistic Snow Accumulation Forecast (DIA)
National Weather Service Denver/Boulder, Colorado
2131 MDT Friday, April 18, 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 (19/00-20/00 MDT): Snow will decrease in intensity by midnight.
Accumulation of up to an inch is possible on grassy areas, but runway
accumulation is unlikely. After that, light snow is expected to end between 3 AM
and 6 AM with additional accumulation under half an inch and runway accumulation
remaining unlikely.
