Metro Boston, North Shore and Metro West: Widespread fog and mist greets us this Saturday morning with temperatures hovering around 60 degrees. Not exactly what we want to see as the weekend begins and considering this is mid-June. There is some good news on the horizon as the heavy rains of yesterday have moved offshore with just a few isolated showers traversing the area early this morning. Also, skies are beginning to partially clear in portions of Connecticut and through the Hudson Valley Region of New York. I caution you that even with any improving and drying conditions the threat for a heavy shower or thunderstorm remains from midday on today.
The trend through this morning and more so this afternoon will be for the fog and mist to lift with a bit of sunshine possible, especially across the interior. Otherwise it stays mostly cloudy through the afternoon. With several areas of weak low pressure, a frontal boundary draped south of the area with a cold front to our west, means that any transition to improving weather will be slow as these players all move slowly out to sea. On the downside is a threat for scattered heavy showers and thunderstorms from midday into the afternoon as the cold front begins to push across central and eastern Massachusetts. There is a slight chance of a severe storm or two as well. High temperatures Saturday in the upper 60s along the North Shore Coast to mid 70s inland. Light winds, except possibly gusty in a passing thunderstorm.
Tonight, the cold front will have moved offshore and skies become partly cloudy on the backside of the departing front. Temperatures will cool down into the 50s with a northwest breeze of 8 to 15 mph on average. A few gusts to 20 mph are possible.
Father’s Day looks to start out mostly sunny and breezy with a trend toward a partly cloudy sky for the afternoon. High pressure will assert itself and take control of our weather. A much nicer day overall than what Saturday presents to us, allowing for outdoor activities to go on without any weather interruptions. High temperatures in the mid 70s to around 80 degrees. Winds may start out a bit breezy through the morning, becoming lighter in the afternoon at less than 15 mph.
Sunday night turns mainly clear and cool. Lows near 50 across some interior valleys to the mid 50s elsewhere. Light winds.
The new work week begins sunny and pleasantly warm as high pressure remains in control. Highs in the upper 70s to low 80s, but there remains the possibility of a developing sea breeze and if that occurs afternoon readings will stay in the low 70s along the shore.
High pressure begins to move offshore and weakens its grip on us. Low pressure and a frontal boundary approach as well. This means an increase in clouds Monday night into Tuesday with a threat for showers, especially for Tuesday. Lows Monday night mid 50s to 60 degrees with highs on Tuesday in the low to mid 80s.
