David Epstein: After the snow, it’s going to rain for a while

That old saying about April showers looks to be true this year.

There’s a Carpenters song from the 1970s that goes “Rainy days and Mondays always get me down.’’

We could add snow to the lyrics for “Rainy Days and Mondays.’’

April snow doesn’t stick around long, so the coating to a few inches that we’ll get should be gone by late Monday or Tuesday.

Blame Monday’s snow on a low-pressure area moving to the south of New England. Wind was kicking up on Sunday and that ushered in colder air from Canada, which is why it’s snowing and not raining.

Snow will mostly fall between 7 a.m. and noon, before turning into rain. Temperatures on Monday afternoon will reach into the lower 40s and melt much of the snow.

When you see maps predicting snow accumulation this late in the year, you’re more likely to see that snow piling up on grassy surfaces. Asphalt absorbs the solar radiation, and, even on cloudy days, roads are warm enough to melt snow. For snow to accumulate in April, temperatures have to be much colder. It’s also more likely to happen at night, as it did during the April 1997 blizzard.

We’ll get more precipitation Tuesday and Wednesday. That should be rain, but don’t rule out some sleet pellets Tuesday afternoon.

Thursday looks to be the best day of the week: lots of sun and temperatures in the mid-40s.

Another storm rolls in Friday, bringing more showers and colder weather. And expect more wet weather next week. April is typically a wet month, and that old saying about April showers looks to be true this year. Let’s hope the May flowers follow.
