Winter, Act III
The bitterly cold President's Day earlier this week appears to be the final gasp of the cold weather regime we had been stuck in for almost five weeks. During that period the mean temperature in Boston was 6.6°F (3.7°C) below the climatological average. This cold regime was preceded by a warm regime of just over five weeks, in which the mean temperature was 10.0°F (5.6°C) above the climatological average. Now, it appears that we are settling into a flow pattern conducive to temperature variations about the climatological average, rather than persistent warmth or cold.
In the short term, we will get a shot of cold air today and tomorrow, on northwesterly flow behind the storm system that passed the region last night. Temperatures moderate for a rather pleasant day on Sunday, before a weak storm approaches us on Monday. This storm is likely to bring some precipitation to the area, but it is too early to tell whether it will be in frozen or liquid form.
Today: Windy, with gradually clearing skies. High 29°F (-2°C).
Tonight: Cold and windy. Low 11°F (-12°C).
Tomorrow: Sunny, but chilly and windy. High 27°F (-3°C).
Tomorrow night: Clear, breezy. Low 20°F (-7°C).
Sunday: Sunny. High 39°F (4°C).
Monday: Snow and rain likely. High 37°F (3°C).
