As I sit down to write this, snow continues to fall across parts of northern and central New Brunswick.  We’re on the downside of April now so most of you are probably ready to move on. Well, not so soon!

I’m watching an area of low pressure that is taking shape over the American Midwest.  It’s expected to intensify over the next couple days, then swing off the coast Friday morning. 

By the end of the week, a strong high pressure system sitting over central Quebec will become a significant piece of the puzzle.  The exact position of that high will be crucial.  Right now it looks like it will sink far enough south to keep most of the “weather” out of New Brunswick and PEI but will likely be close enough to the Atlantic coast to produce a rain/snow mix over Nova Scotia Friday night to Sunday morning.

I believe the low will become almost stationary offshore; that would tighten the pressure gradient - producing a strong, raw NE wind.  Exactly where the rain/snow line will sit is still difficult to nail down. 

I expect to see anywhere from 2-4 cm of snow during the overnight hours of Friday into Saturday for mainland Nova Scotia.  The rain/snow mix will change to snow overnight Saturday into Sunday. There, snowfall totals could be a little more significant: 5-7 cm. 

I will keep an eye on the development of this next weather system as the week goes on.  In the meantime, if you have weekend travel plans in NS, don’t be in hurry to switch to the summer tires just yet.

My tires will stay on for another week! Better safe than sorry! 

PS Last year, the final snowfall of the season in Moncton came on April 28th; Halifax April 15th – 15 cm worth!
