How spring changed to winter in 2 hours

On last Saturday I and my wife went to the local trading centre to make some buys. There was a beautiful spring weather. The asphalt was dry, blew light warm wind, the sky was almost cloudless. We spent about two hours in the trade centre, bought what we needed and even had a dinner in the Indian restaurant with very taste and spicy meals. And when we wanted to return home we down to the first floor and saw the weather changed dramatically. The sky was covered with dark hard clouds, strong wind blew, and it strong snowed. The winter returned. I think even this winter there wasn't such weather like that. To returned home we forced to take taxi, though we were just in a kilometer from home. Next day was a sunny warm weather, while snow was everywhere.
