There's an old belief and Pennsylvania Dutch tradition that if the sun shines on Candlemas Day (February 2), or if the groundhog sees his shadow when he emerges on this day, six weeks of winter will ensue. Groundhog Day has its origins in an ancient celebration of a point mid-way between the Winter Solstice and the Spring Equinox. Superstition has it that fair weather on Groundhog's Day was seen as forbearance of a stormy and cold second half to winter.
