| NAM Winter Forecasts
The NAM Winter Weather plot contains 4 panels. The upper left panel
is the 2m AG Temperature (F). The upper right panel is the Wind Chill
Temperature (F). The lower right panel is the winter precipitation
panel. The gray shading represents percentage of cloud cover (dark
gray=>40%, light gray=>80%). The color contours (magenta, blue,
green, etc) represent liquid equivalent precipitation. The scale is at
the bottom of the plot. The white hatched areas represent where the
precipitation will be primarily frozen precipitation such as snow. The
yellow cross hatched areas represent where the precipitation will be
freezing precipitation such as sleet or freezing rain. The light red
vertical hatched areas are where precipitation is associated with thunder.
The line contours represent surface (2m AG) temperature. The light blue
line is +20C. The light cyan line is 0C. The dark cyan line is -20C.
The lower right plot is the 3 hour snowfall in inches. The color scale is
10 times the liquid precip scale (representing the 10-1 snow to rain ratio).
