You are in mid-latitudes in winter. you experience heavy snow followed by a dramatic drop in temperature as a cold front passes, but for almost 24 hours the weather is clear. then, high clouds appear in the west, thicken to stratus clouds and you receive a light new snowfall (aka snow flurries) but the temperature remains cold.
you have just seen the passage of:

a) a second cold front
d) a warm front
c) an occluded front
d) none of these
