Looking at the news, definitely not in the US Northeast.
Here in the Pacific Northwest, we've had some unseasonably warm weather, which awakened the daffodils, peaches, plums, and apricots. All in bloom in my yard, but there may be frost damage to the delicate fruit blossoms. We had our first rhubarb pie yesterday, now a tradition of Spring. We've also had scallions, and Chinese Chives, which we use for a dumpling filling. A neighbor threw away 2 wine barrels, we scarfed them up, cut in half, drilled holes in the bottoms, and filled with potting soil. Planted radishes, mesclun, spinach, and carrot seeds, then covered with a plastic tent to hold in warmth. They are growign rapidly too.
Wow, only February. I plant with full knowledge that it may be a false "promise" of Spring, but also knowing that, if I don't try, I may miss an opportunity for early treats.
This week, I'll plant chili pepper seeds in the window sill, and in 2 weeks, plan to do the same with tomatoes. They take 6 to 8 weeks to reach outside-size, and by then it should really be Spring!
