Light snow for some Thursday morning

A clipper will bring flurries towards the coast on Thursday, Dec. 14, 2017. (WJAR)

The gusty wind will slowly drop off overnight:

A fast moving "Alberta Clipper" system will pass to our south early Thursday morning bringing a period of light snow to parts of southern New England.

A couple of things are working against this storm, preventing it from bringing heavy accumulation to the area.

First, the storm will pass to our south, placing us on the northern fringe.

Secondly, the cold, dry air will cause the initial snow shiedl to evaporate before reaching the ground.

Lastly, the system will be moving fairly quickly, really only bringing the chance of snow for a few hours from 4 a.m. through 9 a.m.or 10 a.m.

However, with such a cold air mass, the ratio of liquid to snow MAY be higher than 15:1. Meaning that even just .05" of moisture in the clouds can produce an inch of fluffy, light snow. So it seems reasonable that most areas may see a coating to an inch but along the immediate southern coasts of RI & Massachusetts where a bit more moisture is available we may see 1-3" (especially the islands!)

The sun will be out by noontime and it will still be a chilly day BUT the wind will not be as strong as it was Wednesday. A northwest wind around 15-20mph.

Thanks for reading, Mark
