DAYS 1-5 (MARCH 8-12)<\/p>\n\n\n\n
One week of March in the books, and the second week of the third month of 2021 will showcase some of the swings of weather, especially temperature, that the month is known for here in New England. But we’ll start out with a fairly tranquil and chilly day today under the influence of high pressure. As this high center slips to the south, first a warm front will cross the region from west to east tonight producing an increase in cloudiness. While a band of snow will be most prominent along this boundary across northern New England, some areas of snow are also possible here in southeastern New England as it passes by, but not enough to perhaps lightly coat the ground with snow in the pre-dawn hours. Tuesday, the front will be by, the sun will return, and any snow that dusted the ground would quickly vanish as we saw significantly milder air arrive. But that will be just a preview of what’s to come. First, a weak cold frontal boundary will slip into the region nearly unnoticed as it will be running out of forward motion later Tuesday and also have little or no cloud cover with it, and then the boundary will push back to the north again at night. As high pressure sits along the Middle Atlantic Coast and extends offshore, the region will be in a southwesterly air flow through midweek. Wednesday, this air flow may be weak enough so that midday and afternoon sea breeze form along the NH & MA eastern shores. This would hold temperatures back from reaching the levels they reach inland. The other except, both Wednesday & Thursday, will be that a southwesterly air flow comes off ocean water along the South Coast, which would be cooler as well. When we get to Friday, we’ll see cloudiness and a risk of rain showers as a cold front moves in from the north, but the temperature forecast for that day is critically dependent on the timing of this front. It’s a day-five forecast at this point but my early guess is that the frontal boundary will still be north of the WHW forecast area when the day starts, so it will be quite a mild day as well, but not until its end, because it will be a day when the temperature starts to drop significantly as the front pushes through. Obviously, there’s fine-tuning to be done for Friday’s forecast.<\/p>\n\n\n\n
