It will be another clear and very cold day in southwestern Connecticut today, but another winter storm bearing down on the region promises a lot more variety -- everything from possible heavy snow to rain to strong winds to coastal flooding.

The "Hazardous Weather Outlook" issued for late Tuesday through early Thursday by the National Weather Services, indicates there remains a fair amount of uncertainty in what the low-pressure system developing in the Gulf of Mexico will bring.

However, the nasty possibilities include heavy snow, heavy rain, freezing rain, gusty winds, and coastal erosion and flooding.

The storm is expected to arrive late Tuesday morning or early afternoon, and gather intensity overnight into Wednesday -- all depending on its track -- which the NWS admits as of today is a "low-confidence forecast."

Today, meanwhile, should have a daytime high temperature of about 25 degrees. That will feel even colder -- minus-2 degrees -- because of a northwest wind 8 to 11 mph increasing to between 19 and 22 mph.

Tonight should be clear and extremely cold, with a low of about 6 degrees, the NWS predicts. Wind-chill values will feel as low as minus-12.

Monday will be sunny with a high near 18 and a wind chill that feels as low as minus-8 degrees. By nighttime, there may be a slight can of late snow showers.

On Tuesday, the chance of snow sowers continues, as clouds move in. The daytime high will rise to the freezing level for the first time in several days. The chance for snow continues into Tuesday night.

On Wednesday, the NWS predicts, the chance for snow is likely in the morning and into evening.
