Early yesterday, parts of southern New England experienced the coldest temperatures of the winter so far. But it can get colder. This morning there is a slight respite, as cloud cover and light winds have made it a little easier to get about. This mornings lows will range from 15 to 20 on the outer Cape down to 15 below in the typical southern New Hampshire cold spots. High clouds will be thinning out later this morning and this afternoons temperatures will rebound to values similar or just a little less, than yesterdays daytime readings. An arctic cold front will pass through the region late today accompanied by some low cloudiness and virga. Winds will increase and wind chill will become quite noticeable this evening. Tomorrow morning under generally fair skies, temperatures will be well below zero over most of southern New England, probably the coldest readings of the winter so far at Boston and Worcester. If the wind quits and skies are clear, 1 or 2 of the typically colder locations in southern New Hampshire and north central Massachusetts could reach 30 below. The Cape and islands will be a bit milder but will probably pay a price with a stronger wind, as well as snow showers which could dust the outer Cape and Nantucket with up to an inch. Sunday as whole will be the coldest day of the winter with temperatures averaging nearly 25° below normal. This sets the stage for a possibly significant winter weather event here sometime late Monday into Tuesday. It is this system that will bring news making headlines to portions of the mid Atlantic states later this weekend. While it will likely bring at least a period of snow to the interior and mixed wintry precipitation to the southeast New England coast, it will eventually erode most of this frigid air allowing temperatures to be near normal on Tuesday. === The weather observed at WORCESTER, MA at 07:54 AM EST was: === The skies were clear.
