Spring peeks through the clouds

The following says pretty much how it is:

The sun was warm but the wind was chill.
You know how it is with an April day
When the sun is out and the wind is still,
You're one month on in the middle of May.
But if you so much as dare to speak,
A cloud comes over the sunlit arch,
A wind comes off a frozen peak,
And you're two months back in the middle of March.

-Robert Frost

The first day of spring is one thing, and the first spring day is another. The difference between them is sometimes as great as a month.

--Henry Van Dyke
