Warmer air continues to penetrate southern New England as a warm front is lifting north this morning. Radar and surface observations continue to indicate a large area of mostly freezing rain and sleet over interior southern New England, with light rain along the south coast. Precipitation was falling at a moderate rate over the interior. Overall given precipitation and temperatures well below freezing across the interior, much of central and western Massachusetts and southern New Hampshire, will be plagued by ice. Most of the freezing rain will continue this morning. Most areas will change to plain rain by this afternoon, but some patches of freezing rain may continue into early afternoon. Flooding concerns continue this afternoon through tonight for much of southern New England. Expect heavy downpours and a general one to 2.5" of rainfall today. This will cause urban and poor drainage flooding and bring some streams close to bankful. A wind advisory continues for Nantucket and Cape Cod today. Gusts of 35 to 50 mph are possible mainly this afternoon. An isolated thunderstorm is not out of the question along the south coast and across the Cape and islands this afternoon.between highs today will be in the 30s. Precipitation will come to an end from west to east tonight. Lows will range from the mid teens over the northwest interior where skies will become partly cloudy to the low 30s over the Cape and islands. Coastal low pressure near the Carolinas will move up the coast today and cross Cape Cod this evening. Weak high pressure moves across the region Thursday. Low pressure moving through the St Lawrence valley will swing a cold front through New England late Friday. Cold high pressure will move through the northeast Saturday and then move east on Sunday. Another low pressure area will approach Sunday evening bringing more snow and rain Sunday night and Monday. Cold unstable air moves in for Tuesday and Wednesday. === The weather observed at WORCESTER, MA at 07:54 AM EST was: === The weather reported was light freezing rain and fog. The skies were cloudy.
