Plan for a cold Wednesday morning! Wind chills will be in the single digits, while actual temps will be in the teens.

Wednesday and Thursday are cold, mostly sunny and dry with highs in the 20s.

STORM THREAT FRIDAY NIGHT THROUGH SATURDAY

Today’s latest computer guidance still points to a significant storm off the New England coast Saturday. While a storm is likely, the exact location and track are still uncertain. There are many “moving parts” in the atmosphere that have to come together in order for major snowstorm. Some of these moving parts we are tracking are still as far away as Alaska! But at least the pieces are over North America now, and we can sample the atmosphere better with weather balloons.

Of course, the storm track makes all the difference. Below are potential Saturday storm tracks and the impacts. Option #2 is generally what we call the “bench mark” storm track. Storms that pass a few hundred miles south and east of Nantucket favor the brunt of precipitation staying as all snow (not always, but most of the time). The actual bench mark (red dot) over the ocean is around Lat 40°North and Long 70°West. A track closer to the coast or even over southern New England would typically draw in enough warm air to see the snow mix or change to sleet or rain.

Right now, we’re favoring a track near the benchmark or slightly west of it. Things could change, so check back!

The Bottom line: please check back over the next several days as more data comes in. We should start to see a clearer outlook by Wednesday in regards to precipitation type, amounts and location.
