An area of rain moved into the region, with most areas except the south coast, Cape and islands reporting light rain by 5 am. Temperatures early this morning were beginning to fall into the upper 30s across central and northern Massachusetts, but ranged to the mid 40s to around 50 along the south coast. As the front slowly pushes south off the coast this morning, colder air will work into the region through the rest of the day. A weak low will also move along the front. Rainfall will continue through mid afternoon, then will taper off from north to south by days end. Some light precipitation will linger along the south coast through the day. As temperatures fall across extreme northern Massachusetts, there could be a mix of sleet with the rain late in the day. Any lingering precipitation will become mixed with some sleet early tonight, then end by late this evening. However, another stronger area of low pressure will form west of the region overnight, bringing another round of mixed snow, sleet and freezing rain after midnight. Lows will be in the mid 20s to around 30. With shallow cold air in place over the region, more problem weather looms on the horizon. The low is expected to move into the Ohio river valley by Thursday morning, then intensify as it slowly moves across the region on Friday. The resulting weather will be messy, as this system has the potential to bring significant wintry precipitation to southern New England from late tonight into Friday morning, especially across the interior. Snow, sleet or freezing rain will likely affect much of the region, before milder air causes a change to rain, mainly along the coast, during Friday. === The weather observed at WORCESTER at 09:26 AM EST was: === The weather reported was fog.
