Forecast Discussion: A Dense Fog Advisory will be in effect for the eastern Massachusetts coastline, including the Cape and the Islands, from 11PM Saturday night until 9AM Sunday morning. Visibilities may be only a quarter of a mile or less in this area. So, please be careful if you must drive during this time.
After several days of seeing gray, the skies opened yesterday afternoon, and we saw blue skies and sunshine for the first time. A weak high pressure ridge will provide us with some sunshine for tomorrow. However, with a sea breeze today, temperatures will be much cooler, with highs only in the upper 50’s. Patchy fog will return once again this evening, with an isolated shower or two. The showers are due to a weak cold front in Northern New England, which will move southward. Heavier shower activity will move through Monday evening. On Tuesday, a warm front from the Ohio River Valley will move into New England. Our highs on Tuesday will be the warmest of the year so far, as highs will reach the middle to possibly upper 70’s. However, the front will move slowly south, becoming a back door cold front. We will see some showers from the front on Wednesday. By Thursday, a weak high pressure ridge will try to build in from the north. The beginning of the extended weekend will start off cloudy, but we are expecting some sunshine by Saturday.
