I hunt and trap coyotes alot, got 113 this year, and one snare check, i got 24 yotes, and that was rite after a huge blizzard and -30 celsius[&:]. Alot of damn thawing and skinning!!! I find that calling them during a storm is not as successful, but light snow is good. I trap most of mine before or during the storm. After a cold spell is wicked as well as the yotes are hungry and have to work for a living, so they come to my bait site or to a call easily. Calling them is best after a storm, or before, as they can sense the low pressure coming, and need to stalk up on food. Good luck!!!!!!!!!!!!!!!!!!
