The good news is that overcast high level cloud cover prevented it from being as cold as it could have been. The temperature dropped to zero degrees in Boston, and readings from zero to 10 below zero were common over inland areas. Wind chill readings were in the 15 to 25 below zero range overnight. Ocean effect clouds overspread Cape Cod after midnight. Snow showers developed over the outer Cape with visibilities reduced to 1 to 2 miles at Provincetown before daybreak. High cloudiness will persist today, and temperatures will remain frigid, struggling to reach the teens in most areas. Cloudy skies are forecast for tonight with temperatures not as cold as this morning. But this is the calm before the storm. A major winter storm will begin affecting southern New England early Monday morning. Snow is forecast to spread from south to north across all of southern New England during the morning and early afternoon. It will become heavy at times late in the afternoon and throughout much of Monday night. In addition, the wind is forecast to increase to 20 to 30 mph with 30 to 40 mph winds along the coast and even a few gusts to 45 or 50 mph are possible. If this were to occur, then near blizzard conditions may occur Monday night, along with blowing and drifting snow. A mix or change to sleet and rain for a time is possible along the southern coast of Rhode Island and Massachusetts, including the Cape and islands. A winter storm watch is in effect for all of southern New England. Stay tuned to noaa weather radio or your favorite media outlet for the latest on this developing winter weather situation. The storm will exit the region early Tuesday, but cloudy skies will linger through Tuesday night. High pressure centered over Ontario will move east across northern New England today and tonight. It is the cause of the frigid weather. A storm system will develop along the North Carolina coast Sunday night and it will intensify as it heads northeast, passing southeast of Nantucket Monday night, and over Georges Bank on Tuesday. High pressure will follow in its wake for mid week. === The weather observed at WORCESTER, MA at 07:54 AM EST was: === The skies were clear. The prevailing visibility was 10 miles.
