Could New England see more snow this weekend?

24 Apr 2014, 3:41 pm

It’s not April 1st (it’s April 24th). So what I’m about to write might upset you if you happen to live in parts of Vermont, New Hampshire and yes, possibly even Massachusetts.

It might snow through a wide swath of northern and even central New England this weekend.

Remember, I’m just the messenger.

Today, Caribou, Maine, right on the Canadian border, received three inches of snow, the latest they’ve received three or more inches in almost 10 years. It looks like more snow is coming your way – and perhaps quite a bit further south as well.

The latest guidance is trying to slide some snow as far south and east as Boston – yes, Boston – for Saturday night and into early Sunday. Below, you can see what we call the 540 line (the yellow line) which shows where the temperature sits at freezing, or, very roughly, the rain/snow line (it’ll trend northward, but that’s neither here nor there). This is from the perhaps overly snow-happy GFS model:

The one thing the GFS and the NAM model, which is in agreement with the GFS, are probably underselling here is the high April sun angle, which will cut into these snow chances. The good news for any potential snow lovers out there (I seriously doubt there’s anyone in eastern Massachusetts pining for more snow, but I digress) is the majority of the precipitation appears to be falling overnight.

I’m not really buying snow in Boston, at least not right now. I need a couple more model runs to buy into this. But if these model runs keep trending south, we may have to pay closer attention to the possibility of a late April (!) snow event in Beantown. Right now, I’d look for some wet snowflakes north and west of Boston and just a miserable rainy day with temperatures in the low 40s in the city itself.

Regardless, it looks like southern Vermont and New Hampshire and parts of upstate New York and interior Maine will see more snow out of this latest system, Here’s a look at the chances of a one inch or greater snow, from the National Weather Service (again, keep in mind the latest guidance is nudging up this possibility):

Boston – just a heads up, your latest measurable snowfall came on May 10, 1977, when you received a half-inch of slush. In 1987, Boston got four inches of wet snow on April 28th. So yes, it CAN happen. It’s just not exactly, um, common. Your latest measurable snow usually occurs in the last week of March.

Snowfully yours, WeatherNation Meteorologist Chris Bianchi.
