All last week, it was hovering around 0, and frequently above. Then, yesterday, the temperature began to crash. Today was minus 30. Tomorrow it is supposed to warm up again, with a chance of freezing rain.
The really really cold weather would be so much easier to handle if it didn't keep alternating with warm weather. And the sidewalks might be less of a hazard to life and limb if the snow didn't keep melting and re-freezing (=very very icy sidewalks).
