Out on the Cape and islands, the mercury actually rose 10 degrees during the night from evening lows in the 20s. Interior valleys saw temperatures in the teens early this morning, from about Springfield Massachusetts to Keene New Hampshire. Considerable cloudiness today will probably yield a 1 to 3 hour period of showers this afternoon. There might be a passing flurry this morning from southern New Hampshire into the Berkshires but the measurable precipitation, either rain, sleet or wet snow showers, will occur this afternoon. No snow accumulation is expected anywhere except in the Monadnocks and east slopes of the Berkshires in northwest Massachusetts where a coating is possible. Isolated pockets of freezing rain could occur in the deepest valleys from near Keene to greenfield. Highs will range from the 30s interior valleys to the mid and upper 40s coast. Gusty southwest winds of 25 to 35 mph along the coast will make it feel chilly, despite above normal temperatures. Clouds and possibly a sprinkle will linger into this evening but then it will clear later on. It will be relatively mild and the wind will stir the air, with gusts to 30 mph continuing in coastal southeast New England. Lows will be mostly in the 30s except possibly a few 20s in the interior valleys. A brighter day is forecast Thursday with temperatures well up into the 40s, to possibly 50 degrees along the coast. Thereafter, the forecast becomes less certain. There may be a period of snow or rain Friday south of the mass turnpike, as a weak area of low pressure scoots out to sea. === The weather observed at WORCESTER at 06:54 AM EST was: === The skies were mostly cloudy.
