Weather: Arctic JanuaryBy Robert Lindsay Korty
STAFF METEOROLOGIST -- With above normal temperatures continuing over the Pacific, bursts of cold air continue to shoot southward from the North Pole across eastern Canada and the northeastern United States. The large-scale pattern has been consistent for the past several weeks, sending bouts of record-breaking cold south to New England. Temperatures will remain below normal this week with another surge of Arctic air arriving by this weekend. The airmass moving toward the Northeast for this weekend does not look to be as severely cold as recent outbreaks have been, however.
Since these polar airmasses have been in place, there has been relatively little snowfall. Boston is still above normal for the season, owing to the mammoth event that fell in early December, but totals for this month are behind normal levels for January. With strong, Arctic high pressure in place, storms have been shunted south or to sea. A few weak, fast-moving storms (called “Alberta clippers” after the province in which they usually form) have breezed across the Canadian border, and another may bring a quick inch or so of snow on Thursday.
Today: Sunny and windy. High 25°F (-4°C).
Tonight: Becoming cloudy, with a low near 17°F (-8°C).
Thursday: Scattered snow flurries, high 32°F (0°C).
Friday: Sunny but windy and colder. High 22°F (-6°C), low 10°F (-12°C).
