Seems like often the "after 70 degree" spring snowstorms often come pretty late (here in Kansas) as well. I can remember some in April. And I still have photos on Facebook from March 30th, 2009 big snow - well after 'first day of spring'. You never know, with Kansas! :-)
Gee, what a surprise. 12+ inches on average after the 1st 70 degree day in NE Colorado. For that matter, most of the high plains.Chinook (strong downslope) = 70 degree weather in Feb/Mar.Strong low pressure in KS plus a cold front = strong upslope = heavy snow in NE Colorado.KDEN average snow: Mar: 10.7" Apr: 6.8" May: 1.1". So it adds up.
