Accompanied by wind gusts to around 40 mph, the temperature dropped sharply between 10 and 15 degrees in just a few hours. Snow showers fell along and just behind the front, briefly lowering visibility. The arctic front will move quickly offshore this morning, but strong northwest winds will prevail today, with gusts between 35 and 45 mph common, strongest over the Cape and islands. In sharp contrast to yesterday, high temperatures today will range only from near 30 over the high terrain of western Massachusetts and southwest New Hampshire to the upper 30s over the Cape and islands. Skies will be partly cloudy tonight. Low temperatures will range from the lower teens in southwest New Hampshire to the mid 20s over the Cape and islands. Varying amounts of clouds and sunshine are expected Saturday, with high temperatures generally in the upper 30s and lower 40s. The next chance for any precipitation is not likely until Sunday night and Monday, when one or more low pressure areas travel along a front, stalled just south of New England. Early indications suggest that most of the precipitation will fall as snow. === The weather observed at WORCESTER at 07:54 AM EST was: === The skies were clear.
