STAFF METEOROLOGIST -- March 1 is regarded as the first day of spring for many meteorological and climatological analyses, but it will continue to feel like winter as the new month begins. For much of this winter, the polar vortex, which usually sits over the North Pole, has been divided into two lobes, with one positioned over Quebec. This has facilitated several outbreaks of Arctic air across the northern United States. Again this week unseasonably chilly air will remain in place across New England. This is the first winter in three years to have temperatures at or below normal.
At least the amount of daylight is growing rapidly; there will be eleven hours and ten minutes today. The vernal equinox, a more traditional definition of the beginning of spring, occurs in less than three weeks, on March 20.
Today: Variably cloudy. High 32°F (0°C).
Tonight: Partly cloudy. Low 20°F (-7°C).
Saturday: Cloudy, light snow overnight. High 38°F (3°C), low 28°F (-2°C).
Sunday: Mostly cloudy and cool. High 35°F (2°C).
