Developmental Probabilistic Snow Accumulation Forecast
National Weather Service Denver/Boulder, Colorado
0216 MDT Thursday, May 15, 2014

--------------------------------------------------------------------------------
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 (15/12Z-16/12Z): Scattered rain showers will continue
through the rest of tonight and Thursday as a upper level disturbance moves
across the airport.  At this time, temperatures will remain warm enough for all
rain.  Any snow accumulation is not expected.
