Forecast discussion: Boston began to warm up Saturday afternoon, after bitterly cold temperatures swarmed all over New England. The official low temperature at Logan Airport Saturday morning was two degrees. At Warwick, RI, T.F. Green Airport reported a low of three below zero. Parts of northwestern Rhode Island had readings of 5 to 10 below zero.

The good news is that Saturday night will not be a three blanket night. Some milder air has been slowly moving north, thanks mostly to the switch to southwest winds. Lows during the overnight will be in the lower 20’s. As we head into Sunday, we will continue to have southwest winds. This will also help bring more moisture over the area, leading to overcast skies. We will even see some rain showers beginning by the mid-afternoon. Precipitation will become heavier Sunday night into Monday, as a strong cold front inches its way closer to the east coast.

During Sunday night, temperatures will actually rise, making it almost balmy as you head to work or school on Monday. However, do not pull the Bermuda shorts out just yet. The strong cold front will be passing through eastern Massachusetts by the afternoon, and our temperatures will plummet through the afternoon. Any precipitation will end as snow showers Monday night, before skies begin to clear.

Once again, another blast of Arctic air will stay over the region. High temperatures on Tuesday will struggle to reach 20 degrees. We will be go to single digits Tuesday night, before temperatures slowly rise by the middle of the week to seasonable conditions. A weak frontal boundary will bring the chance of snow showers by Thursday evening. Any precipitation will end by Friday morning. The computer models are unsure of how to handle a low pressure system in the Ohio River Valley for next Saturday. Some models keep precipitation making it to Virginia, while the American model brings precipitation all the way into New England. At this time, I have low confidence in the forecast after Friday afternoon.
