Three short lines, and almost nothing happens: wind pushes snow around. That's the whole scene, and the poem seems happy to leave it there.
What matters is the phrase "every which way." It's casual, almost spoken, and it tells us the snow has no direction. It isn't falling neatly or drifting toward anything. It swirls, scatters and changes course, and the short, broken lines on the page seem to scatter a little too.
The speaker never says how they feel, so the mood comes from the picture. It could feel calm, like watching a snowstorm through a window, or a bit restless, since nothing in the scene settles. Judging by the plain wording, the speaker is simply watching and letting the weather be what it is. The poem asks us to slow down and notice one small moment of motion, without explaining it or turning it into a lesson.
