Return of Winter?

Temperature -2. Cloudy. Some wind from the East.

It snowed all night. In the morning it was white everywhere. However, it began melt more or less into slush quite soon. As can be seen in the picture of the neigbourhood, the roofs and other spots a bit off to the side remained snowy to the afternoon. Then I spotted water dripping past our window from the roof. But is it really return of winter? The official definition of it is challenging, meteorologists say, if you feel winter is back you can say it's back. Anyway warmer weather is forecast. Spring is coming step by step :)
