T. S. Eliot wrote that April is the cruelest month.

Judging from the forecast, though, cruel weather could not wait for April.
A day or two, including today, will be well above freezing, with sunny skies, and much melting.
Then, later this week, temperatures will plunge: it will be at or sub-freezing DAY AND NIGHT with a bitter winter wind adding that wind-chill factor. That for several days straight.
Then the temperature wobbles upward somewhat for the weekend maybe.

Not sure how March is going to "go out" but right now the extremes are being worked in a pendulum swing.
