Forecast discussion: Although we are entering the last full week of March, it sure did not feel like that in Boston. Temperatures only reached the lower 40’s on Sunday. Over the last few hours, temperatures are beginning to drop, thanks in part to a cold front that passed through Southern New England a few hours ago. Temperatures will fall into the middle teens this evening, with high temperatures not even reaching 30 degrees Monday, despite bright sunshine.

High temperature forecast for March 24, 2014

As we head into Tuesday, I am still watching the computer models for a potential Nor’Easter that will arrive Tuesday evening. The low will form off the coastline of Georgia and South Carolina. We will actually see some precipitation from a weaker low pressure system over New York. By the start of the evening commute, the precipitation may change over to some rain showers. By Tuesday night, the low will strengthen to a winter storm. The problem now is if the low moves closer to Southern New England, or continues to move out to sea. Right now, it appears the models agree that the low will track well east of Cape Cod. However, the Cape and Islands will see the possibility of blizzard type winds and moderate snow. At this time, Boston has a chance at seeing gale force winds of 35 mph with light to moderate snow into Wednesday. It is possible Boston receives about 4-7 inches.

We will return to drier weather on Thursday, and highs will reach the lower 40’s. By Friday, winds will turn to the south, and high temperatures will reach the lower 50’s. However, a cold front will bring some rain showers through the day. As we head into the weekend, the computer models are having a slight disagreement. All the models except the American model brings us dry weather for Sunday. But, the American model keeps the low further south and stationary off Long Island Sound. So, we would see heavy rainfall all day on Sunday. For now, I believe in the other models, and will give us partly sunny weather by the afternoon. Slightly cooler air will arrive next Sunday, but high temperatures will be in the upper 40’s.
