Weekend could be cold and clear, or warm with precipitation
While Thursday and Friday promise to be pleasant and sunny, there is a chance that we could experience snow or rain during the weekend. The large scale flow over New England will be southwesterly over the coming days, and Boston will be on the edge between the cold inland air and the warmer ocean air during the weekend. The precipitation will occur in this transition region, and whether or not we get snow and/or rain will depend on which side we end up on. One extreme is cold temperatures (low 30s) and clear skies, while the other is warm temperatures (high 40s) and lots of precipitation. We will most likely end up somewhere between the two, with temperatures around 40°F and intermittent rain during the day or snow during the evening.
