Is This The Start of Spring?

For the past 3 days, we had glorious, sunny weather. The rain have stopped and the sun shine throughout the day. The temperatures was in the mid teens unlike the cold we encountered in the middle of June. Another sign was that the plants buds are starting to grow and little leaves are now appearing and so have the weeds. In the supermarkets, blooming flowers are beginning to be sold and the mall are having sales to clear their winter products. Is this the end of winter and the coming of spring? I certainly hope so.
