Some Snow Likely Sunday Night into Monday

Sunday Morning Update:

Model guidance continues to tick in with a bit more moisture for the Sunday Night and Monday period. That said, they also continue to suggest there’s a threat for a bit of sleet and rain at times during the day on Monday.


Weak(ening) low pressure will approach the Northeast and New England Sunday night and pass south of the area during the day on Monday. This weather system will spread a shield of moisture into the area beginning overnight Sunday and it will linger over the area throughout a good chunk of the day on Monday.

With cold air bleeding into the region tonight and strengthening its grip on the area tomorrow, most, if not all, of the incoming precipitation should be in the form of snow.

Right now, this looks like a modest snow event…with a general 2 to 4 inches of snow expected here on the Cape. If we see some sleet or rain mix in (low probability but still possible) amounts will be a bit lower. Similarly, there are still a couple of forecast tools which suggest a small chance for a bit more snow (say 3 to 5″?) as slightly greater amounts of moisture get involved.

Either way…whether it’s 2 inches of snow or 5 inches of snow, this looks like a relatively low impact event, all things considered.

The combination of the snow falling on a holiday weekend and the intensity of the snow being mostly on the light to moderate side (and drawn out over a rather extended period of time) should leave most area roadways in OK shape for the most part. Furthermore, winds will be rather light throughout the event and temperatures will be close to the freezing mark – meaning road treatments will work well and solar insolation will assist in melting snow on paved surfaces.

This isn’t to imply that we won’t see some slick spots and snow covered roads and that you shouldn’t take it easy if planning to be out and about late Sunday night and during the day on Monday. It is simply to say that we are not likely to encounter an intense “thump” of heavy snow causing quickly deteriorating travel conditions.
