Peak summer heat & humidity set to blanket Boston & New England Thursday through Sunday, peaking Friday. Temps hug the low 90s, dew points to the 70s, heat index values to near 100°. Daily pop-up showers & t-storms during this stretch. #mawx #nhwx #riwx #boston #newengland @bostonglobe.com
The latest Euro El Niño update indicates that sea surface temperatures are likely to rise by an average of 4°C above the norm across the Equatorial Pacific by November/December. New England is likely to see an extended summer and a warmer winter. More storms, too, but more rain than snow.
Rain totals from this storm have pushed 2-5" for interior New England; expect another inch or so for RI & Southeastern Mass. over the next couple of hours. A few more afternoon storms enter the picture to boost totals further. Stay alert to avoid flooded streets. #newengland #boston #mawx
A flash flood warning has been issued ahead of a fast-moving cluster of storms for portions of Central and Northern Rhode Island and Southeastern Massachusetts through 11:45 a.m. Torrential rain of 1-2"/hr is likely at times to flood roads. #mawx #riwx #boston @bostonglobe.com
Very strong downdrafts and downpours with this cluster tracking along the Mass Pike. Be careful out there on the roads. Visibility is near zero. #mawx #boston @bostonglobe.com
Flash flood warnings continue for Hartford, Springfield, and Northern MA between Lowell and Leominster. Expected heavy rain to Boston within the hour. #mawx #ctwx #riwx @ @bostonglobe.com
Keeping an eye on the Berkshires, look out for some minor to moderate river flooding across Western Mass. today. The Hoosic River in Williamstown is likely to splash over quite a bit today. #mawx #berkshires @bostonglobe.com
A potent low slowly rotates through New England on Wednesday morning. #mawx #boston @bostonglobe.com

Flood risk increases from I-495 west to the MA/NY & CT/NY border. Multiple repeat storms with downpours may dump 2-3" with local totals closer to 4-5". Varying terrain, saturated soils = flooding potential Wednesday morning. www.bostonglobe.com/2026/07/28/m... @bostonglobe.com #mawx

A crawling & potent storm brings scattered heavy rain to Western New England on Tuesday. Some flooding from excessive runoff possible. Wednesday, the flood risk shifts east to Boston, Providence, etc. Multi-day rain totals of 2-3” #mawx #nhwx #ctwx #boston @bostonglobe.com
July has been hotter than average across all 6 New England states. Rain? We have more rain than average across MA & RI. If Boston ends up with more rain than average, it would be the 1st month since October that we've seen this happen. Good for drought! #mawx #riwx #boston @bostonglobe.com
As cooler, dry air settles over New England, it'll be a great stretch for some open windows at night — nature's A/C, as lows slip into the low 60s for the rest of the week & weekend. #mawx #boston #nhwx #riwx @bostonglobe.com
The Red Sox go for the all-time win streak record in franchise history today with the doubleheader. Weather tries to cool the streak: A spot shower or thunderstorm may cause a delay, mostly 2-8 pm. Delay possible. www.bostonglobe.com/2026/07/22/m... #mawx #boston #redsox @bostonglobe.com
A flash flood warning is in place for portions of Plymouth County until about 10:45 p.m. Ponding on roadways. #mawx #boston @bostonglobe.com
Smoke clears out of Southern New England this morning, setting up a beautiful Sunday! #mawx #boston #wildfire #smoke @bostonglobe.com
Lobe of smoke returns Saturday afternoon, but disguised with passing showers & thunderstorms. Could smell and taste at times, especially with showers bringing smoke to the surface. All gone by Sunday; highs are seasonal (upper 70s & low 80s) both days. #mawx #boston #riwx #nhwx @bostonglobe.com
Wildfire smoke is becoming much more common across Boston & New England. Check out the boom of days with poor air quality from wildfire smoke (PM 2.5). As wildfires spark further east across Canada, Boston sees higher chances of smoke. More smoky days ahead. #mawx #nhwx #riwx @bostonglobe.com
A couple of severe storms are pushing south into Massachusetts for the next two hours. Heavy downpours and wind gusts up to 60 mph. Be careful on the drive home for those of you north of the Mass Pike and along the MA/NH border. #mawx #nhwx #boston @bostonglobe.com
