Metro Boston, North Shore and Metro West: The showers on Wednesday were mainly over with by mid morning with the remainder of the day staying gloomy and cool. Temperatures were several degrees cooler than originally forecast, especially along the coast where a persistent ocean breeze kept temperatures hovering around 60 degrees. Certainly not what you want to see in early June after having a Summer tease earlier this week. Unfortunately there is going to be one more day of clouds, rain and cool temperatures before we return to drier and more seasonal weather conditions over the weekend.
Low pressure emerges from the Ohio Valley by early on Thursday and then pushes across the waters just south of New England through the day. This disturbance will spread a rain shield across southern New England Thursday with the steadiest rain probably falling into the early afternoon. The heaviest rain may very well fall south of our area across southeast Massachusetts with lighter amounts toward the New Hampshire border. There will be widespread fog as well. Showers are expected to persist through the afternoon with diminishing chances of showers Thursday night as the low pressure pulls away toward Nova Scotia. It will remain cool with high temperatures on Thursday only in the upper 50s along the coast to low 60s inland. Those readings are about 10 to 15 degrees below the early June averages. Overnight lows in the low to mid 50s. Winds become northeast and stay light at 10 mph or less.
On Friday clouds may persist in the morning, especially along the coastal plain. There is also a chance of a spot shower or two and once again the better chance for this will be along the coastal plain. Otherwise, skies become partly cloudy from west to east during the day with a few clouds hanging around Friday night. Temperatures will recover into the 70s across the interior, however along the coast highs struggle to reach 70 degrees. Lows dip into the 50s at night. Winds backing to the northwest under 10 mph with a chance of a northeast breeze developing along the coast.
More improvement in the weather can be expected over the weekend, although there does remain a slight risk of a hit or miss shower Saturday afternoon. High pressure will move in overhead providing the nicer weather. Partly cloudy skies on average through the weekend, although there will be intervals when the skies are mostly clear, especially Saturday night and Sunday. Highs climb to the low 80s inland, mid 70s along the coast both days. Nighttime lows in the 50s.
A frontal boundary approaches Monday bringing an increase in clouds later in the day and a chance of a shower across the interior at night. Highs generally in the 70s to low 80s across the area, coolest near the shore.
