One traditional Irish legend regarding Imbolc is about the Cailleach, the old hag. If the Cailleach knows winter will last for a while yet, she will make sure the weather on Imbolc is bright and sunny so she can gather plenty of firewood. If Imbolc is a day of foul weather it means the Cailleach is asleep and winter is almost over. Very similar to the groundhog and his shadow! The weather was pretty nasty so I guess spring will arrive soon!
After this latest winter storm, I am certainly looking forward to the onset of spring as the days lengthen with each passing week.
