Developmental Probabilistic Snow Accumulation Forecast
National Weather Service Denver/Boulder, Colorado
0228 MST Tuesday, February 20, 2018
--------------------------------------------------------------------------------
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 (20/12Z-21/12Z): There will be a few flurries before
sunrise but no snow accumulation is expected.  A weak disturbance will bring
another shot of very light snow between 2 PM and 8 PM this afternoon and
evening.  Any accumulation will be under a half of an inch of snow.
Temperatures will struggle into the upper teens this afternoon.  Surface winds
will be east at 5-10 mph.
