Developmental Probabilistic Snow Accumulation Forecast (APA)
National Weather Service Denver/Boulder, Colorado
1523 MST Monday, December 01, 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 (01/17-02/17 MST): A winter system is expected to bring accumulating
snowfall beginning late Tuesday night through the day Wednesday.  4 to 6 inches
are forecast for KAPA, with the greatest chances being Wednesday morning when
snowfall rates between .5 to .75 inch an hour will be possible between 5 AM and
11 AM.  Expect temperatures to be cold enough for snow to begin accumulating by
5 PM Tuesday evening, therefore all snow is expected to stick to runways once it
begins.
