The lovely poem"The Snowman" by Wallace Stevens contributed by KW below, I'm inspired to suggest two more poems appropriate, in their very different ways, to our current weather conditions. (Both are a little long for this blog, so I've linked them to the full text off site.)
"A Country Boy in Winter" is by Sarah Orne Jewett, the author of The Country of Pointed Firs and other classic tales of rough, 19th Century rural New England.
"A City Winter" by Frank O'Hara offers a very different, very 20th Century take on the present season. The Selected Poems of Frank O'Hara were published in a handsome new edition back in February of this year.
