October severe thunderstorm risk Friday evening across Western Mass. & CT — localized wind gusts up to 65 mph. Lower risk of strong downdrafts as these storms move east into the night & weaken by the time they reach Boston. #mawx #ctwx #riwx #boston @bostonglobe.com

Winter Outlook released today by NOAA. Super El Nino fingerprints all over it. Warmer and wetter across New England. More coastal storms, but less snow. Winds are now westerly over the equator, which means the Polar Vortex may release fewer Arctic outbreaks. #winter #mawx #riwx #nhwx #boston

Fall foliage update — Northern New England is now past peak in chunks. High color & peak foliage are working south. Southern Vermont, New Hampshire, Central Maine, & the Berkshires are this weekend's hot spots. Saturday: clearing but blustery; Sunday is good! www.bostonglobe.com/2026/10/15/m...

After Northern Maine saw a coating of snow last night, our next snow chances arrive Saturday morning. Mid to high elevations across Northern New England can see a scattered coating of wet snow on the backside of our next system. #nhwx #vtwx #mewx #boston @bostonglobe.com

Isaias remnant moisture arrives during the Patriots vs. Raiders game. Temps around 60, a breeze to 15 mph, & drizzle to light showers lurking — likely turning steady during the second half. Pats are 1-0 at home vs. Raiders with same weather. #boston #mawx #patriots #raiders #nfl @bostonglobe.com

Hurricane Isaias update — now a Cat 3, will likely make landfall as a Cat 2 later tonight/early Saturday by the Alabama-Florida border. Storm surge to 9 ft in spots, rain totals pushing 15" for some, & multiple tornadoes. Dangerous situation about to unfold by the Gulf Coast. #tropics #isaias

050

Ken Mahan @weatherken.bsky.social · 09/10/2026

Major Hurricane Isaias — set to make landfall later today near the Florida-Alabama line, likely as a Cat 2 storm. There's a decent tornado risk on top of coastal flooding, strong winds, & flooding rainfall. #flwx #alwx #isaias @bostonglobe.com

Ken Mahan @weatherken.bsky.social · 08/10/2026

El Niño continues to intensify — seas ~4°C (7.2°F) above average by Dec. We've seen El Niño impacts in the Pacific tropics. New England saw the 7th-warmest summer on record, a September nor'easter, & likely less snow this winter. www.bostonglobe.com/2026/10/08/m... #elnino @bostonglobe.com

Ken Mahan @weatherken.bsky.social · 08/10/2026

Northern Lights alert! There is a low-to-medium chance of the Northern Lights breaking out over New England tonight, under mostly clear skies, too. On the northern horizon or phone for Southern New England, potentially higher in the sky up north. Times? 11p-12am, 3- 5:30am. Set your alarm!

Ken Mahan @weatherken.bsky.social · 07/10/2026

Tropical Storm Isaias — expect this storm to rapidly intensify into a Category 2 or 3 hurricane before making landfall — likely between LA & FL Panhandle. Even bad storms occur in quiet seasons; it looks like Isaias will tap into record-setting seas & a light enough window of wind shear. #flwx

Ken Mahan @weatherken.bsky.social · 04/10/2026

A pair of fronts passes through New England on Monday morning (spot shower chance in the am), with chilly air behind it. Tuesday morning will be spent in the 30s & 40s for most! #mawx #riwx #ctwx #nhwx #mewx #vtwx #boston @bostonglobe.com

Ken Mahan @weatherken.bsky.social · 30/09/2026

The last 2 Octobers delivered massive Northern Lights events across New England & the U.S. Will see see a "threepeat"? We are quickly coming down from Solar Max 25, but the chances aren't zero. www.bostonglobe.com/2026/09/30/m... #aurora #northernlights #mawx #riwx #nhwx #boston @bostonglobe.com

Ken Mahan @weatherken.bsky.social · 28/09/2026

Nor'easter is losing steam but still looks prominent across the Northeast. The center will drift over Southeast New England late Monday, with scattered light showers rotating over the region as it does so. Tuesday remains cloudy with a few slivers of sunshine cracking through during the afternoon.

041

Ken Mahan @weatherken.bsky.social · 27/09/2026

Nor'easter update — winds start to relax, but still gusts of 25-45 mph. Rain totals for Boston sit at ~1.5", with 2-6" as you head south to the Cape. Expect another 1-2" today for Boston to Worcester County and through much of Rhode Island. Flooding possible in spots. #mawx #riwx #boston

072

Ken Mahan @weatherken.bsky.social · 26/09/2026

Technically speaking, this is not a tropical storm, but visually, it's very similar. You can see the center of circulation just south of New England. Why not tropical? This nor'easter does not have a warm core fueled by warm seas, but is fueled by clashing air masses over an old frontal boundary.

0152

Ken Mahan @weatherken.bsky.social · 26/09/2026

As the nor'easter inches closer, we should see these bands build & slide north, putting Greater Boston into heavier rain within the next several hours and lasting into the night. Expect some water ponding on roadways and in low-lying areas.

021

Ken Mahan @weatherken.bsky.social · 26/09/2026

The heaviest rain for this nor'easter comes Saturday mid-afternoon/evening and into Sunday. Wide range in rain totals by Monday, depending on where bands & the heavier clusters set up. Winds remain strong through Saturday night, a touch better on Sunday. #noreaster #mawx #nhwx #riwx #boston

061

Ken Mahan @weatherken.bsky.social · 26/09/2026

The sun rises to reveal the deepening nor'easter as it approaches New England on Saturday morning. #noreaster #mawx #riwx #boston @bostonglobe.com

071

Ken Mahan @weatherken.bsky.social · 26/09/2026

Night nor'easter — wind gusts are reported to reach 50-70 mph across the Cape, with a 70 mph gust in Wellfleet. Bands of heavy rain rotate in throughout Saturday; expect rain totals of 1-3" today, similar for Sunday—heaviest by the coast. Winds to 55 mph continue. #mawx #riwx #boston #noreaster

Full rainbow on display in Central Mass!

Look at the budding nor'easter with a clear center of circulation! #mawx #riwx #ctwx #nhwx #mewx #noreaster #boston @bostonglobe.com

Ken Mahan @weatherken.bsky.social · 25/09/2026

#Nor'easter arrives on the southern #NewEngland coast around 1- 3 p.m., #Boston ~ 5. Friday night, things deteriorate. Saturday is the worst day — rounds of heavy rain, strong winds, flooding in spots & along the coast. Sunday will be about 60-70% as intense as Saturday, with more breaks.

071

Ken Mahan @weatherken.bsky.social · 23/09/2026

High wind & coastal flooding watches are popping up across Southern New England — Friday evening through Saturday night, renewed for Sunday. Timing: Friday night — Sunday night Impacts: 4-7" of rain, 10-foot breaking waves, winds up to 55 mph. Scattered flooding & power outages. #boston #mawx

161

Ken Mahan @weatherken.bsky.social · 22/09/2026

Coastal storm/nor'easter update: Timing is Friday through Sunday, with multi-day totals of 4-5" for some. Minor coastal flooding & beach erosion for south-facing beaches. Storm track still messy; likely stalls just south of New England. Wind gusts of 50 mph. #mawx #riwx #noreaster #ctwx #mewx

051

Ken Mahan @weatherken.bsky.social · 21/09/2026

Tracking a coastal storm that might turn into a nor'easter late Thursday/early Friday. Models are split on a classic nor'easter with gusty winds, heavy rain, & coastal flooding to a complete miss. I'm thinking we see more of a clip than a miss here. www.bostonglobe.com/2026/09/21/m... #mawx

0176

Ken Mahan @weatherken.bsky.social · 20/09/2026

Patriots vs. Steelers will see steady light rain, with cool temperatures in the 50s. Light winds under 10 mph. Hopefully the #Patriots hold on to the ball! #mawx #nfl @bostonglobe.com

020

Ken Mahan @weatherken.bsky.social · 20/09/2026

Some confidence in a potential tropical disturbance in the North Atlantic by next weekend — New England should see coastal showers and some heavy rain. Still very early — we'll see how much juice is left in a front that breaks down over the region and what emerges; models are all over the place.

Ken Mahan @weatherken.bsky.social · 20/09/2026

The best spots with the best timing! 🍁

052

Ken Mahan @weatherken.bsky.social · 13/09/2026

As steady to heavy rain advances northeast across Southern New England, expect a few minor flooding incidents as between 2-3" is possible for areas along the Mass Pike & south. Sun might come out an hour or two before sunset @bostonglobe.com #mawx #riwx #ctx #boston

0135

Ken Mahan @weatherken.bsky.social · 10/09/2026

A new record for the 1st hurricane of the season in the Atlantic sets tomorrow (9/11). It's been over 100 years since we've seen a hurricane-free season, so could that record be next? Of the 5 tropical storms this year, we've seen a record-low ACE too. www.bostonglobe.com/2026/09/09/m...

071

Ken Mahan @weatherken.bsky.social · 08/09/2026

Increasing clouds on Tuesday, a few spotty showers north of Mass. Wednesday sees scattered showers enter later in the evening. Otherwise, it's feeling like fall is around the corner! #mawx #nhwx #riwx #boston #newengland @bostonglobe.com

Ken Mahan @weatherken.bsky.social · 04/09/2026

Fall foliage outlook for New England! Best chance for a normal foliage season we've seen in a few years. Last winter's snow totals + some good precipitation in summer despite the heat should make the leaves pop better. www.bostonglobe.com/2026/09/04/m... #mawx #riwx #nhwx @bostonglobe.com

0225

Ken Mahan @weatherken.bsky.social · 01/09/2026

The latest date for the 1st hurricane of the Atlantic season in the satellite era (since 1966) sits at September 11. We're absolutely going to challenge that date! #tropics

Average temps compared to the seasonal norm for meteorological summer across Massachusetts. 90% of the state finished hotter than usual, including Boston, Worcester, and Springfield. #mawx #boston #summer @bostonglobe.com

010

Ken Mahan @weatherken.bsky.social · 01/09/2026

Tropical Storm Edouard is expected to make landfall today near the TX/LA border. 6-8" of rain for most; scattered flooding likely through Wednesday. 5th named storm of the season, well behind the average pace. Still no hurricanes. Spin-up coastal storms remain the theme for this season. #tropics

020

Ken Mahan @weatherken.bsky.social · 31/08/2026

It's the last day of meteorological summer! New England as a whole will end much warmer than average & drier than average (except for SW CT). Likely the 3rd or 4th warmest summer on record across the region. #mawx #nhwx #riwx #vtwx #mewx #ctwx #boston @bostonglobe.com

Ken Mahan @weatherken.bsky.social · 31/08/2026

Nepal natural disaster explained: excessive heat = thinning, unstable glacier. The mountainside glacier collapsed, releasing a massive pool of water that acted as a tsunami, once slamming the barrier lake. Water & debris flow then compressed (like putting your thumb over a hose = more power).

112

Ken Mahan @weatherken.bsky.social · 28/08/2026

New England as a whole will likely end this meteorological summer with a 3rd-place finish for warmest on record. Many cities, including Boston, Manchester, Concord, & Portland, will be top-5. 9 straight years of above-avg summers for #NewEngland. #mawx #nhwx #riwx #ctwx #vtwx #mewx #boston #summer

023

Ken Mahan @weatherken.bsky.social · 27/08/2026

Friday should see scattered showers and thunderstorms pop up over Central & Coastal New England during the late morning through the afternoon — this includes Greater Boston. But after Friday, we'll see a beautiful Saturday and Sunday across the region. #mawx #riwx #nhwx #boston @bostonglobe.com

000

Ken Mahan @weatherken.bsky.social · 27/08/2026

Tropical Storm Dolly has formed! Wind speeds are 40 mph & tracking towards the Leeward Islands. Moderate shear will keep this storm at tropical storm strength, but still, potentially heavy rain is likely for the Northern Leeward Islands and Puerto Rico later this weekend. #tropics #dolly

020

Ken Mahan @weatherken.bsky.social · 27/08/2026

The disturbance in the Main Development Region continues to battle tough conditions — likely to emerge as Tropical Storm Dolly within the next 24-48 hours. Track sends the storm to the Northern Leeward Islands as a Tropical Storm with heavy rain by Sunday. #tropics #dolly @bostonglobe.com

030

Ken Mahan @weatherken.bsky.social · 26/08/2026

Thursday: our pattern flips — humidity builds, breezy, scattered showers & thunderstorms during the afternoon & evening. Western New England may see an isolated severe t-storm. Highs to the upper 70s to low 80s with dew points around the mid-60s. #mawx #boston #riwx #nhwx @bostonglobe.com

020

Ken Mahan @weatherken.bsky.social · 26/08/2026

Rip currents have been more problematic in recent years along Mass. & New England beaches. Check out the jump in rip current alerts issued by the NWS since 2019. More offshore weather volatility is responsible for the jump. #mawx #beach #ripcurrents #boston @bostonglobe.com

Ken Mahan @weatherken.bsky.social · 25/08/2026

The tropics are booming across the Pacific with 7 storms & disturbances. The Atlantic currently has two areas of interest, with the Main Development Region trying to flare something up over the next couple of days. #tropics #atlantic #pacific #hurricane @bostonglobe.com

Ken Mahan @weatherken.bsky.social · 24/08/2026

Temps & rain chances this week for Boston, really all of New England. Remaining seasonal, spotty showers rotate into Western & Northern New England each afternoon until a steadier system arrives later in the week. #mawx #riwx #nhwx #boston #newengland @bostonglobe.com

Hurricane Bob struck New England 35 years ago today & is the last time a landfalling hurricane reached the region. Bob formed during a Super El Nino season & is the strongest landfalling hurricane during such a season since 1950 (3 landfalling hurricanes total) www.bostonglobe.com/2026/08/19/m...

Ken Mahan @weatherken.bsky.social · 18/08/2026

Between two ferns? Great show/movie. But how about between two fronts? Wednesday is the hottest day of the week. Mid-80s for most, upper 70s along the immediate coast. Mostly dry with a mix of sun & clouds, but a spot shower chance is possible, especially across NW & SE #NewEngland. #boston #mawx
