A flow of air off the Atlantic has kept us cool, cloudy, and drizzly much of the day and this will keep big thunderstorms from firing up and moving into the region this evening, as they may very well have done if we were not in this air mass. Showers should hold off in most locations of eastern MA until after 10PM. Before then, there will be some areas of fog and drizzle, under an overcast sky.
What’s up this weekend? I think we try to break out a little on Saturday but any sun that does burn through the clouds would just destabilize the atmosphere and allow showers and storms to fire up. Also, a couple fronts and troughs moving through will provide lift for shower activity even without sun. I don’t expect a washout, but not the best day. By Sunday, high pressure building overhead should allow for more sunshine and warmer air.
A peek at next week: Summer!

Love those temperatures for next week but we got to get there first and then the trolls on BZ blog will be complaining its too hot.
As for thunderstorms don’t see a widespread severe weather outbreak tomorrow. I am going to go with a 1 which is MINOR meaning should thunderstorms fire they will remain below severe levels but this may need to be bumped up to a 2 if it looks like isolated severe weather will develop.
Just had a tstorm roll through Framingham. Heavy rain but no wind and fairly steady thunder. I need to review Jimmy James scale definitions but I think he’d call it a 1 or even .5
Is it possible to have the scale definition posted in a sidebar
My husbands company picnic is in Ashland today. Glad to see there will be sun
Here is a breakdown of the thunderstorm index and I hope this will help people make their plans.
1. MINOR meaning garden variety thunderstorms that remain below severe levels
2. MODERATE meaning isolated severe weather but nothing widespread.
3. SEVERE meaning widespread severe weather.
4. EXTREME widespread severe weather with the chance for isolated tornadoes.
What I look at in determining the rating to give is the storm prediction center, what the models are saying, and discussions from the National Weather Service. I may not be right all the time as was the case back on June 1st when I only gave a MODERATE impact for thunderstorms and as we know there was EXTREME Level Activity across parts of SNE but I will do my best and never hype anything.
Thanks JimmyJames. This was definitely a 1. And I just stepped onto the porch and was surprised how cool it is. Thermometer says 54 but feels colder
Have a great Saturday everyone
