b. Draw isotherms in red ink every 10 F including 50 F.
c. Draw fronts in the proper places, using the standard colors and symbols.
2. Analyze the surface plot for Jan 10, 2017. Do the same analyses:
a. Draw isobars in black ink every 4 mb, including 00.
b. Draw isotherms in red ink every 10 F including 50 F.

b. The 1982 case featured a 24 inch snowfall at Denver, Colorado (DEN) while for the 2017 case, Denver received 0 inches of snow. In fact, there was no precipitation at all.
