Turning Colder Tonight…Some Snow Expected Over the Weekend

A cold front is crossing through the region today, bringing gray skies and a period of wet weather to the area this morning. A few spots saw some brief downpours early this morning and registered a quick .3 to .4 inches of rain…continuing our very wet February.

Precipitation will shift offshore over the course of the day today and drier and colder air will build in from the northwest as chilly high pressure shifts eastward into the Northeast and New England. This bubble of high pressure will crest over the region Saturday and then shift quickly seaward Saturday night.

Fast on its heels will be an advancing low pressure center…one that will race eastward from the Tennessee River Valley Saturday morning to the waters east of the Mid-Atlantic by Saturday night and then to a position well east of Nantucket by Sunday morning.

This relatively weak storm center is far from an “ideal” winter weather set-up for Southern New England but will bring just enough moisture northward into a marginally cold atmosphere to produce some snow around the region Saturday night and first thing Sunday morning.

Here on the Cape, a “mild” east and southeast wind off the water will result in a rather wet snow which will put a bit of lid on snowfall totals despite being closer to the system’s deeper moisture. In fact, if precipitation doesn’t fall heavily or steadily enough Saturday night, snow may mix with or change over to rain at times (and if that is the case…accumulation totals would be limited to a slushy inch or so).

Snowfall totals around the region should be rather manageable and regardless milder air will return very quickly behind this departing storm, so melting when ensue shortly after the storm ends. As a result, I don’t anticipate too many issues around the area…other than some slick/snow-covered roads very late Saturday night and first thing Sunday morning.
