The second half of the weekend is not looking as bright and sunny as Saturday was. Although high pressure remains positioned across New England a pesky wave of low pressure is sliding along a stationary front to our south. Originally thought to slide well offshore and bring some cloudiness to Cape Cod and the Islands, the high and mid level clouds are streaming into southern New England with scattered showers as far north as metro New York City.
As a result of the low passing to the southeast of Nantucket later today and this evening the sky cover is now expected to range from partly to mostly cloudy today. The further north of Boston you are the better chance of a bit more sunshine. If you head toward Cape Cod or Rhode Island and Connecticut it will remain mostly cloudy to overcast with a slight chance of a sprinkle. Temperatures in the 60s early today will top out in the mid 70s coast to near 80 through the interior. Light winds under 10 mph.
As the low pulls away overnight the skies will slowly begin to improve. Mostly cloudy conditions give way to a partly cloudy sky by morning. Lows in the mid 50s inland to low 60s on the coast. Winds near calm.
Back to more sunshine and becoming warmer on Monday. An upper level disturbance will sit to our west with high pressure in control at the surface. With very dry air in place any showers associated with the disturbance should dry up over New York State and not impact the metro Boston area. Generally a partly cloudy sky with highs climbing into the low and mid 80s, about 80 on the beaches. Light west to southwest winds under 10 mph. Overnight, a few clouds as temperatures fall to the upper 50s interior to about 65 in Boston.
Both temperatures and humidity will increase into the mid week period. Fair skies with mostly sunny days for Tuesday and Wednesday. Increasing levels of humidity as highs reach the mid to upper 80s. A few areas may stumble into the low 90s on Wednesday as we bring back summer heat and humidity. Overnight lows in the mid 60s to near 70 degrees.
