The heat is turning up today, inland anyway. Along the shore, a cooling sea breeze has taken over. As of 3:00PM, Boston’s Logan Airport is a comfortable 72 with a wind off the water, while inland, temperatures in the 80s to near 90 are common. The humidity is on the increase, but is not too high as of yet. That humidity will continue to increase tonight through most of the day tomorrow, and the heat will be on in all areas tomorrow due to a southwest wind. Some instability due to the boundary of the ocean breeze and the inland warmth, along with a minor disturbance, may set off a few isolated showers or thunderstorms this evening. An approaching cold front will bring isolated to scattered thunderstorms to the region Thursday afternoon and evening. At this time, I still do not see any widespread severe weather with this, but any storms that do form can still become strong to locally severe. The main threat appears to be torrential downpours which could cause localized flash flooding. However, most people will not see this tomorrow.
High pressure pushes in Friday with a change to cooler and drier weather. And this trend continues Saturday with still cooler air but dry weather. Low pressure will bring unsettled and continued cool conditions on Sunday. This cooler than normal air that establishes itself over the weekend is expected to continue early next week as well.

I’m fortunate to have access to A/C both at home and at work. With that said, I am looking forward to tomorrow to see how hot it gets………… At least here in extreme eastern Marshfield, I dont think we made it to 80F today. On the western edge of town by Route 3, I’m guessing it hit the mid 80s………. I do hope that the thunderstorms are not too bad tomorrow and avoid the areas affected by the recent tornadoes. Unfortunately, that area is probably the bullseye again for best instability and heat content of the air.
Severe Thunderstorm Watch up until 11pm for parts of SNE. Look out for the possibilty of some isolated severe weather tonight and tomorrow so thunderstorm index at 2 which is MODERATE.
Severe Thunderstorm Warning for Western MA and Severe Thunderstorm Watch as far east as Middlesex County although NWS believes only the western sections of Middlesex are more likely to be affected. Let’s see what happens.
Boston currently has a NNE wind.
Update: Severe Thunderstorm Warning has now extended eastward not too far from the city of Worcester.
This may be just round one for some areas tonight and round two could be in tomorrow afternoon and evening. Again Moderate Level Activity tonight and tomorrow since there is the chance for some isolated severe weather.
