Forecast discussion: Well, it was a little cooler than the 87 degrees recorded at Logan Airport in Boston on Sunday. With the extra cloud cover, the high temperature at the Airport was only 74 degrees on Monday. We will feel the full effects of autumn over the next seven days, along with a lot of cloud cover and cooler temperatures.
We are expecting a cold front over Northern New England to drop into our region during the overnight. This will shift our wind direction to the northeast, keeping cooler air coming off the water over the region. Also, we may see some drizzle or isolated showers that are being created by the front. As we move through Tuesday, we will receive more moisture from another weather system.
There is a wave of low pressure off the coast of North Carolina. The computer models are still unsure how much precipitation we will actually receive, because the models disagree on how close the low’s center comes to the east coast. Based on the current model runs, they are beginning to agree that the center will remain well offshore. So, we will see off and on drizzle and showers right through Wednesday, with periods of light rain during the afternoon.
A weak high pressure ridge coming down from Canada will finally push the low pressure center out to sea by early Thursday morning. However, we will still remain with cloud cover, as I am only expecting limited sunshine. We will finally see some stars in the skies Thursday night, as we will be in the direct ridge axis of the high. But, once the ridge moves off to our east, a cold front in the Midwest will bring showers and possibly light to moderate rain into eastern Massachusetts for Saturday.
The front will move off to our east by early Saturday night, and we will end the weekend with mostly sunny skies. A weak low pressure system coming down from the Great Lakes will bring the risk of a few showers Monday night. At this time, there appears to be a disagreement between the European and American models for the seventh day of the forecast. It is possible the high pressure system on Sunday is able to keep the low from moving into New York until early Tuesday morning.
