I hope everyone was able to enjoy the Holiday Weekend, and if you have today off as well, the weather turns out just fine. No more 70s in the forecast, but if today brings you to the Topsfield Fair, the local pumpkin patch or just out for lunch, it'll be comfortably cool with temps running in the mid 50s to near 60. Sun fades this afternoon behind increasing clouds, but it remains dry.
In a sign of the times, last night's rain in southern New England turned into snow across the higher terrain of northern New England. Mount Washington picked up 3.6" of the white snow and some of the ski resorts had snow covered slopes about halfway up the mountain.
For us, clouds thicken tonight, and rain arrives after midnight. That rain sticks around tomorrow, through early afternoon, and that means a damp and dreary day. Rain tomorrow is steadiest across SE Mass, with it more sporadic from Boston, points, north and west. Despite the rain letting up at times, temps are likely stuck in the middle 50s with an onshore wind locking in low clouds and pockets of drizzle. I'd say tomorrow is clearly the worst day of this upcoming week.
The rest of the week is seasonably cool with temps near average, if not just below it. A few pockets of drizzle linger early Wednesday, but the afternoon is dry. Then during the evening, a strong cold front punches through with a few showers/thunder across the area. It's out of here by Thursday morning with the sun back in place.
Another brief shower possible gain Friday afternoon and again Sunday morning. With that said, most of each day is still dry, so there's not much rain in the forecast beyond tomorrow. The coldest air mass that moves in is Friday night and Saturday morning. At this point, I'd expect temperatures near freezing in most suburbs Saturday morning.

Although my forecast was busted today, there was one good thing that came out of it.
Stability.
That gray overcast that hung over the eastern half of the Commonwealth provided a stablizing influence to our atmosphere. The cool air blowing in from the ocean kept the temperatures in the upper 50s and low 60s all the way back to Metrowest. While that makes for lousy short-and-t-shirt weather, it is poison to thunderstorms.

Wild temperatures yesterday---from the 80s down into the low 60s in just an hour AND some heavy duty thunderstorms. The reason was a cool front that dropped in from Maine. That front is in western New England this morning and it's a chameleon as it will become a warm front and try to warm things back up during the day.

What a day! Breakneck temperature swings, thunder, tornadoes in Western Mass....and we're still in late May!

You have another warm & humid day with many towns repeating yesterday's weather. That means we start with clouds & fog for a bit before hazy sun gets going. That hazy sunshine will boost temps up into the low 80s by early to mid afternoon across much of the region. At the same time a cool front will begin dropping out of Maine (backdoor front) which will quickly send temps from the 70s/80s down into the 50s/60s by late afternoon & evening. Also, when this front rams into the warmth & humidity it will spark a few showers & thunderstorms during the afternoon.
