Developmental Probabilistic Snow Accumulation Forecast (APA)
National Weather Service Denver/Boulder, Colorado
2135 MDT Friday, April 18, 2025

--------------------------------------------------------------------------------
This developmental product contains the probabilities (%) that the given snow
amounts (inches) will occur at Centennial 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 APA.
[T (trace) means more than zero.]
--------------------------------------------------------------------------------

Discussion (19/00-20/00 MDT): Snow will diminish in intensity by midnight. Until
then, snowfall rates of a quarter to half an inch per hour are expected, but
accumulation will be mainly on cold surfaces, but some slush may accumulate on
runways during the heavier snow. After midnight, light snow will taper off and
end between 4 AM and 7 AM, with additional accumulation of a half inch or less.
