Forecast discussion: During the overnight hours, patchy fog that has stayed near the coastline will slowly move inland into Boston, as winds diminish and dew points increase. It will be quite warm tonight, with lows in the middle 40’s. For Wednesday, it will be another spring like day, as highs reach the middle 60’s, despite a northwest winds. However, as the day progresses, colder air from Maine will work southward. The colder air will remain along the Atlantic seaboard. In weather terms, we refer to this as a back door cold front. The cooler air will arrive by tomorrow night, as lows fall into the upper 30’s. On Thursday, it will feel cooler, as highs only reach the lower 50’s. By late Thursday night, a weak low pressure system will bring a few showers for Friday morning. We will remain with scattered showers throughout the day, before ending early Saturday morning. High pressure will build into the Northeast for the weekend. Except for a slight chance of showers for Monday, the weather will remain dry. High temperatures will also slowly increase to the upper 60’s on Tuesday.
