Strong high pressure was building into far northern New England and southern Quebec early this morning. However, a strong stationary front remained well south of New England. A little light rain was falling across Cape Cod and the islands early this morning with temperatures in the mid 30s. Elsewhere across southern New England, skies remained cloudy with temperatures in the upper 20s to lower 30s, except in the mid 30s along the south coast. An area of moisture will move into the region, between the strong high and stationary front, late this morning through the afternoon. With cool temperatures, the precipitation will fall as a mixture of snow and sleet across most areas, with a mix of rain and sleet along the south coast, Cape Cod and the islands. This will make for a hazardous commute from late this afternoon through tonight. If you must travel, please drive slowly and allow extra time to reach your destinations. As temperatures remain near or below freezing at the surface, warm air will move up above the region tonight. This means a mixture of sleet and freezing rain for most of the region tonight. Warmer air will eventually work into the south coast, with a change over to rain after midnight tonight. Precipitation will mainly be rain over Cape Cod and the islands. Motorists will still experience very hazardous traveling conditions across most of southern New England overnight, especially north of the Massachusetts turnpike, as well as the Connecticut valley region, mainly on secondary roadways and untreated surfaces. Strong low pressure will move east from the Great Lakes region late tonight and Friday, pushing across central New England during Friday. First, the front south of the region will finally move north of the area Friday morning, causing the mixed bag of winter weather to change over to rain by early afternoon. Then, a cold front will sweep across the area late Friday and early Friday night, bringing to an end this extended period of winter weather. Skies will become partly cloudy overnight Friday. The outlook for Saturday calls for mostly clear and more seasonable weather with highs in the lower to mid 30s. === The weather observed at WORCESTER at 08:11 AM EST was: === The skies were cloudy.
