Yeah the maps that use 925mb and above temps for snow work well in winter, but not in April when the lowest 1,500-2,000ft gets torched pretty easily.
In that verbatim solution it's likely 1,000ft+ for snows in the Greens/Whites.
Funny how the snow maps evolve with time of year too. They are the same maps as January, but with very different environmental factors.
P-Type algorthim's lol. SFC temps never get below 34-35F.
