Weather: The Second MonthBy Robert Lindsay Korty
STAFF METEROROLOGIST -- Depending on how dour one is, February inspires images of gray skies and dreary weather or skiing and seasonal recreation. Either way, it is definitely winter. The January that just ended was the coldest month in seventy years with a mean temperature of only 20.7 °F (-6.3 °C); February 1934 was the last month to have a lower mean temperature. (In fact, Boston's all-time record low temperature of -18 °F (-28 °C) was set February 1934.) Last year, the first with a cold winter in a while, the temperature dropped to 0 °F (-18 °C) at Logan twice during February.
But after a January during which repeated blasts of Arctic air moved into New England, even normal February weather feels almost spring-like. Temperatures should clear freezing for the next few days, as a storm center passes west. The milder air advected ahead of the storm will be enough to ensure rain rather than snow in Boston Tuesday night. While it will be seasonably cool, a new planetary-scale pattern has replaced the one that dominated last month, which let air to slide from the North Pole down to New England. It is certainly too soon to claim that Arctic outbreaks are over for the season, but none are poised to move south this week. The potential for a winter storm exists for this weekend; it will be monitored this week.
