The average high this time of year is around 80.  We hit 68 in Boston.  While it was a cool day with lots of clouds, it wasn’t a bad start to the weekend as tee times and ball games worked out just fine.  Those dry conditions change tonight. 

We do track some early evening showers slowly moving in from the west, perhaps some light showers arrive by 8pm in Worcester but likely take until at least 9pm or later to move into Boston and many coastal towns. They’ll be hit and miss this evening, so I wouldn’t necessarily count on constant downpours for a late dinner date or a concert, but I’d keep the umbrella handy for some drops here and there.  

I do expect widespread downpours late overnight and into tomorrow morning (4am-11am Sunday) as an unusually strong area of low pressure pushes in tons of moisture and a strong easterly wind. East to southeast winds increase tonight, gusting 35-45mph by Sunday morning, with the highest gusts across the Cape and Islands.  Many towns pick up 1-2″ of rain, few towns locally higher, and with a good chunk of that falling in a short period of time in the morning, there may be some localized flooding in poor drainage areas as well as urban areas. Rivers and streams should be able to handle the water. 

While Sunday’s forecast features the bulk of the gusty winds and downpours in the morning (even a few thunderstorms over far southeast Mass if we break into the warmer, more humid air), we’ll still have a few leftover scattered showers in the afternoon amid some dry spells as well. Winds along the coast also diminish in the afternoon.  Temps tomorrow widely vary from the upper 50s/lower 60s across the North Shore/Northern Mass and Southern New Hampshire to the mid 70s across far Southeast Mass.  If you’re trying to sneak in some beach time tomorrow, the best place to try tomorrow afternoon would be the Cape and Islands.  

The weather looks better next week with temps in the 70s to near 80.  It’s a fast pattern, so we’ll periodically catch a few showers/thunderstorms.  The next best chance for that is Wednesday.  I did put a drop on the 7day forecast for The 4th, but it doesn’t look like a major storm moving in.  There may be some showers either late Friday or early Saturday… exact timing to be determined, but that’s what that drop is there for.  

Enjoy the rest of the weekend and try to stay dry!
