Good weather at Candlemas is taken to indicate severe winter weather would follow. In Scotland the emergence of snakes from the ground became Groundhogs in the United States and Canada. This aspect of Candlemas evolved into Groundhog Day. If the Groundhog could see its shadow,there will be 40 more days of winter.
If Candlemas day be dry and fair,
The half o the Winter's to come and mair;
If Candlemas day be wet and foul,
The half o the Winter's gane at Yule.
