Unsettled Sailing ahead

We are in for an extended period of unsettled weather. Tuesday will be cloudy with a good chance of light rain or snow in the early morning. We shall be pretty much straddling the polar jet stream all week, and as a succession of low pressure troughs move along it, they will bring clouds and the possibility of rain or snow. After each trough passes, the skies will clear a little, affording a glimpse of some sun. The high pressure ridge building to the south and west of us will pull colder air over us as the week progresses, increasing the probability of snow. However, we will be spared heavy snow by the fact that air masses from Canada tend to be too dry for significant accumulation by the time they reach us. The end of the week should see a gradual warming as the flow changes back to southerly.

Today: Light rain probable overnight possibly continuing through the morning. Cloudy and cool. High 38F (3C).

Tonight: Some clearing of the clouds, keeping temperatures down. Low 26F (-3C).

Wednesday: Mostly cloudy with a chance of rain or snow. High 34F (1C). Low 22F (-5C). Winds picking up to around 15 mph (25 kph).

Thursday: Again cloudy with a chance of precipitation. High 41F (5C). Low 30F (-1C).
