A tranquil day on Wednesday will lead to stormy conditions later at night into Thursday. Low pressure moves northeastward out of the Tennessee Valley early Wednesday and is expected to redevelop as a coastal low near the Chesapeake Bay and move toward Cape Cod Thursday. Travel will be significantly impacted along the I-95 corridor Wednesday, south of New York City and Thursday in New England.
After a dry day Wednesday the onset of precipitation should begin during the evening hours. Snow is expected to break out early in the evening, with sleet and eventually rain mixing in overnight, except remaining snow and sleet north and west of the city. By Thursday it should be a mostly rain and snow mix, changing back to all snow in the afternoon as the storm center passes northeastward toward the Maritimes and drags colder air behind it. This will be a messy storm, with several inches of snow accumulation likely before any mixing takes place. In and around Springfield may see 2 to 5 inches accumulation, with amounts of 4 to 7 inches north and west. If the track of the storm changes one way or the other we could see more rain mixing in or higher snow values.
Friday should turn out somewhat blustery as colder temperatures return on brisk winds. We can expect the sunshine to return however.
Saturday starts out sunny but the clouds will be on the increase during the later part of the day which signals the approach of another coastal storm. The track of this storm remains somewhat uncertain, but we could see anywhere from a significant snow event, to a glancing blow if the storm moves far enough out to sea. If this storm is to impact us the timing is likely late Saturday night through Sunday. Also, there is a much better chance of this event bringing all snow locally. Confidence is low on the track this storm takes, but as we approach the late week period the computer models should have a much better handle on what this storm has in mind.
