Forecast discussion: It was a nice day for Boston, although temperatures are still below normal for this time of the year. According to Logan Airport, we only reached a high of 35 degrees today. However, we did see a lot of sunshine through the day, but the colder air coming down from Canada, as well as a slight pressure gradient helped create strong winds from the west and northwest.
Over the last few days, I have been worried about a secondary low forming over North Carolina and bringing some possible snow to parts of eastern Massachusetts. Well, the primary low pressure system is centered over Alabama at this moment, and has brought rain, snow, and ice to New Jersey south to North Carolina, and as far west as northern Arkansas. However, a high pressure system over western Michigan will move east and will keep the precipitation from moving further north. There is a chance that the lower Cape and Islands will see some flurries Monday morning, but a coating of snow is all they will see by the evening commute. Otherwise, it will remain cold, as temperatures will not make it to 30 degrees.
The high will begin to move out to sea by Wednesday, allowing for the winds to turn back to the south. This will allow warmer air to return into New England, as highs on Wednesday increase into the middle 40’s. A low pressure system will bring some showers by the evening commute on Wednesday, and will remain rain into Wednesday night. The boundary will move offshore by Thursday morning, and we will have limited sunshine.
A new low pressure system in the central U.S. will bring a frontal boundary right into Rhode Island Friday night. We will see some possible showers during the evening commute, and there may be enough cold air aloft to turn the precipitation to snow showers Saturday evening. The precipitation will change to rain by the middle of Saturday morning, and end by the early evening. The cold front will help bring some cooler air over the area next Sunday, as our highs only reach the upper 30’s to near 40 degrees.
