Moving clouds

I just spent more than a minute watching the clouds moved by. Is it just my imagination or clouds do move faster here? If these thick, grey clouds stayed for awhile, the weather forecast might be right - that we will be getting sleet showers tonight and hopefully snow tomorrow. But tonight is still not here yet as the sky is still bright out there eventhough it's already 7.30pm. Quite a contrast from the beginning of the year when I had to walk back from class in the dark at 5 plus. How I dread those days.
