Boston Weather: 67.0°F | Overcast

Weather: A Wet Welcome Back to Classes

By Greg Lawson
Staff Meteorlogist

The large high pressure center which gave us such clear, beautiful skies yesterday has finally been chased out to sea. A band of storms are quickly plowing their way up the coast. The preceding clouds arrived before dawn and the rain will arrive sometime mid-morning. The surface temperatures may still be below freezing, giving us a brief period of freezing rain earlier on. The strong southwesterly winds aloft will ensure light, persistent rain throughout the day. They will also pipe in much of the warmer southern air. Temperatures will slowly climb as the day progresses and melt any new ice from the rain earlier. In addition to increased temperatures we will also see increased wind strength. A cold front will actually be approaching from the northeast associated with a low up off Nova Scotia, a "backdoor" cold front. It will not pass over us thanks to the strong southerlies aloft, but it will come close enough to help wind strength reach close to 30 mph on Wednesday.

The rain strength will increase late tonight as a second surge of storms arrive. The temperatures will continue to climb on through Wednesday with the rain ending early afternoon. Temps will peak at close to 50F! Once the rain leaves we will settle in to a large high pressure center from the south. Expect seasonally mild temperatures throughout the rest of the week from the favorable southwesterly upper air pattern.

Tuesday: Overcast. Light rain from mid-morning on through the day. Freezing rain early on. Climbing temps throughout day. High 42F (6C).

Tuesday Night: Heavier rain. Southeasterly surface winds increase. Temperatures continue to rise. Low 40F (5C).

Wednesday: Rain persisting through early afternoon. Winds speeds increasing up towards 30 mph. High 50F (10C). Low 36F (2C).

Thursday: Seasonably mild. Partly cloudy. Highs in the upper 40s (8C to 10C).

Friday and Beyond: Cooler but still mild. Mostly clear as high pressure settles in. Highs in the low 40s (4C to 6C).
