Developmental Probabilistic Snow Accumulation Forecast
National Weather Service Denver/Boulder, Colorado
1952 MST Sunday, February 17, 2019

--------------------------------------------------------------------------------
This developmental product contains the probabilities (%) that the given snow
amounts (inches) will occur at Denver International Airport during the respec-
tive 6- or 12-hour periods.  The probabilities indicate the amount of snow that
will fall from the clouds.  They do not consider the amount of melting that may
or may not occur on various ground surfaces. [T (trace) means more than zero.]
--------------------------------------------------------------------------------

Short Term Discussion (18/00Z-19/00Z): Periods of light snow or flurries will
be possible through the night.  Total snowfall is expected to be around an inch
through Monday morning.  The next round of snow will move in late Monday
night.

Long Term Discussion (19/00Z-20/00Z): Areas of light snow will occur mon night
through Tuesday.  At this time accumulations should be on the light side with
amounts up to an 1" through Tuesday with a low probability up to 2".  The snow
will be rather fluffy and have low water content.
