Developmental Probabilistic Snow Accumulation Forecast (DIA)
National Weather Service Denver/Boulder, Colorado
1521 MST Monday, December 01, 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 (01/17-02/17 MST): Another winter system is expected to bring
accumulating snowfall beginning late Tuesday night into Wednesday evening.  2-4
inches are expected to accumulate on runways, with the greatest chances expected
Wednesday morning when snowfall rates between .25 to .5 in an hour will be
possible between 5 AM and 11 AM.  Temperatures will be cold enough for snow to
stick to runways after 5 PM on Tuesday.  There is about a 20% chance that rain
showers begin before temperatures reach below freezing that could lead to icy
conditions to develop before the snow begins to accumulate (20% rain chance
between 4 PM and 5 PM Tuesday evening).
