A series of relatively weak storms will skirt the Boston area this week, creating brief chances for light snowfall at various times. The first of these chances will come this morning, as a low pressure system passing to our south may spread some light flurries through southern New England. Next, another weak low will pass to our north overnight, bringing light snow or rain showers to the area through tomorrow afternoon. Finally, another weak disturbance will bring the chance of light snow or rain showers during the day on Friday.
