The high pressure enveloping southwestern Connecticut early today will give way to a low-pressure system as Monday progresses.

But, according to the National Weather Service, this low and another one behind it that will arrive tomorrow will both track to the south of Long Island. This is expected to trigger showers late tonight into tomorrow, but there likely won't be much in the way of measurable precipitation.

Expect clouds to increase, with dull sunlight because of increasing high cloudiness. There also will be another chance for rain Thursday. This weekend will see warmer-than-normal temperatures for this time of year.

Sunset today is at 6:07 p.m., and there will be almost exactly 11 hours of sunlight Monday. The moon will rise at 3:53 p.m. Sunrise tomorrow will take place at 7:09 a.m.

This evening's high tide will occur at 9:01 p.m. in Bridgeport and 9:04 in Stamford/Greenwich.
