Spying a couple of new daily high records for today. Springfield/Westfield and Manchester, NH, should set new records. Boston may fall short. #mawx #nhwx @bostonglobe.com
Heat returns to Boston & New England on Tuesday. Heat alerts in place. Temps in the 90s + dew points near 70 = heat index to 105° in spots. A rare Enhanced Severe Risk in extreme Northern New England on Tue. PM. 75 mph gusts, hail, & tornadoes possible. #mawx #vtwx #nhwx #mewx @bostonglobe.com
After a gorgeous weekend, a swath of heat returns to New England. Back to the 90s we go to start the week (Mon-Wed) #mawx #boston #riwx @bostonglobe.com
Here's how 2026 stacks up to the annual number of 90°+ days across Boston over the past decade. #mawx #boston @bostonglobe.com
For 7 years in a row, New England's average temp from January to June has been above the 30-year norm (1991-2020) #mawx #riwx #nhwx #vtwx #mewx #ctiwx #boston #newengland @bostonglobe.com
The Atlantic remains quiet thanks to intensifying El Niño & Saharan Dust. (strong wind shear, dry air aloft, & cool SSTs in the MDR) CSU dropped their forecast to 9 named storms (inc. Arthur), 4 hurricanes, & 1 major. Even U. of Arizona dropped the 20-named-storm forecast to 13. #tropics
Boston was having the hottest start to summer on record before Tuesday's cool day. The same goes for Concord, Providence, Milton, and the top 5 for many others. After 1 day in second place, Boston will return to the hottest summer start top spot after this week wraps. #mawx @bostonglobe.com
Heavy rainfall continues across Cape Cod, the South Coast, and the islands. Minor water ponding on roads is likely for Falmouth, Barnstable, Sandwich, Bourne, and Nantucket until about 2-3 pm. #mawx #boston #capecod @bostonglobe.com
Afternoon update! High pressure to the north of Boston has blocked out the rain so far. But rain will creep north later Monday. Flooding risk remains over CT/RI & SE Mass. on Monday night & Tuesday morning. 1-3", local totals to 5". #mawx #ctwx #riwx #boston @bostonglobe.com
Heavy rain for So. New England Sun night-Tuesday am. Backbuilding storms along stalled front, between 1-4" from the Mass Pike, #Boston, & South. 4-8" local totals in Southern CT/RI. Flooding is expected there, too much for drainage systems & dry, brittle soil. #mawx #riwx #ctwx @bostonglobe.com
Boston tops 100° shortly after 3 p.m. — new daily high record. Westfield/Springfield sets new daily high record with a 97° high (old record 94° in 2018) Manchester, N.H. sets new daily high record with 97° high (old record 95° in 1968). Can still bump up. #nhwx #mawx #boston @bostonglobe.com
Thursday sees peak heat & humidity across Boston & New England. Highs pushing 100°, heat index values to 110° as tropical air blankets the region. Numerous record highs likely. Boston's all-time high sits at 104°. #mawx #nhwx #riwx #vtwx #mewx #ctwx #boston #newengland @bostonglobe.com
Folks in the Berkshires and Southern Vermont — stay weather aware during the commute home with potent storms pushing in. Damaging wind gusts up to 70 mph and small hail are possible. A very low tornado risk. The severe t-storm watch expires at 8 p.m. #mawx #vtwx #nywx @bostonglobe.com
The heat dome influence arrives Wed. across New England; sinking air holds stagnant heat over the region, increasing Thurs. and lingering Fri. Highs on Wed. to 90s & near 100. Dew points to the low 70s = heat index values pushing 110° — be careful out there. #mawx #boston @bostonglobe.com
Boston is having the driest year on record to date, with a 9" precip deficit in 2026. We need much more rain, or we're staring at extreme drought, wildfires, wells running dry, & poor crops. Especially with El Niño ramping up. www.bostonglobe.com/2026/06/24/m... #mawx #riwx @bostonglobe.com
After a beautiful day on Wednesday, Thursday will see temperatures push into the 80s with light rain entering New England during the afternoon, reaching Boston late. A couple of spot downpours, but generally light. #mawx #riwx #nhwx #boston #newengland @bostonglobe.com
Look at the streamer totals across Southeast New England, some 3"+ local totals. A few vehicles were submerged. Additional rain totals throughout Tuesday, with the highest targets the Cape with up to 1" locally. www.bostonglobe.com/2026/06/22/m... #mawx #riwx #boston @bostonglobe.com
Beneficial rain on Monday, but heavy rain early on Tuesday flooded portions of SE Mass. & So. RI. Between 2-3" of rain flooded roads, submerging vehicles in Fall River. Flood alerts have dropped, but expect another wave of showers & t-storms during the day. #mawx #nhwx #riwx @bostonglobe.com
Not quite sure what the NWS will find for the Worcester tornado-warned cells. A little bit of anomaly on the debris detector, we'll see what the survey team discovers. Reports of funnel cloud over Spencer/Leicester. #mawx @bostonglobe.com
All is done for the night! But these two inflow V-notches were very impressive from earlier. Wouldn’t be surprised of NWS sends a team and one of these is confirmed. #mawx @bostonglobe.com
A severe thunderstorm warning has been issued for Worcester County and Southern Middlesex, pushing through 7 pm with strong wind gusts up to 60 mph and heavy to torrential rainfall. #mawx @bostonglobe.com
Two tornado warnings encroaching on Worcester for the next hour. Very tight couplets on the velocity. Could have one or both on the ground at this time. Seek shelter immediately! #mawx @bostonglobe.com
