Update

It now appears that the storm is making a quicker arrival. So, the snow will start in Boston by 9 PM, and little earlier on the north shore. It will snow most of the night, but warmer will come in by 9 AM monday morning, changing the snow to rain. The steady rain will be over by 1 PM. I now expect 2-4 inches of snow on Cape Ann and 1-3 inches in Boston. Scroll down for more details on the week's forecast.
