Skies over southwestern Connecticut today will be sunny but cold, according to the National Weather Service.

A decidedly less bright forecast, however, is in the offing for the weekend.

Today, the NWS says, the daytime high temperature will be about 27 degrees, with a north wind between 10 and 15 mph. Tonight will be partly cloudy, with a low around 18. A calm north wind will register at only about around 6 mph.

Tomorrow will be warmer, as the sun helps the high temperature peak at 35. Clouds move in at night, but the temperatures should fall to just above the freezing mark.

On Saturday, there is a chance of light rain as skies remain cloudy and the temperature rises to the high-40s. Overnight, the likelihood of rain grows, mainly after 3 a.m.

Sunday promises to be the warmest day in more than a week, with a high temperature in the low-50s, but the chances of rain -- with occasional downpours -- are rated at 70 percent by the weather service.

Because of the possibility of significant rainfall from Saturday night through Monday morning, the NWS has issued a hazardous weather outlook for the region during that period.
