Winter Storm Chloe, a fast-moving clipper system from Canada, will make a quick pass through our area Wednesday night into Thursday morning. It's its timing that's going to make for a difficult morning commute, thus impacting travel.
Temperatures overnight will be down into the low 20's. The type of snow depends on temperatures. First of all, it's going to be plenty cold enough for snow to accumulate on all surfaces, including roads. With temperatures in the low 20's, we'll experience a light, fluffy snow instead of a heavy, wet snow, as shown by the forecast vertical profile of the atmosphere below. These large snowflakes will allow for the snow to accumulate fast, despite its light to moderate intensity.
The timing of this snow will also be an issue. We know it's going to accumulate, but with snow falling from around midnight through 8AM on Thursday, you'll likely be off to a late start to work or school because most roads will be snow-covered. View our latest school predictions here.
The HRRR future radar shows the widespread, light snow associated with the clipper passing through the southern coast of New England early Thursday morning:
Based on my thoughts and forecast mentioned above, I'm thinking up to an inch or two will accumulate with the heaviest totals at the coast, which is where moisture content will be the highest.
