@matthewcappucci.bsky.social constantly impresses me with his meteorology writing and speaking.

Vivid writing by @matthewcappucci.bsky.social about a flight aboard @noaa.gov’s “Kermit” into the eyewall of Hurricane Melissa. Cappucci conveys the power of a Cat 5 hurricane bearing down on Jamaica. [gift link] wapo.st/3L7FWMs

The remnants of Tropical Storm Mario will bring scattered heavy downpours, isolated strong to severe thunderstorms, and the potential for flooding to southern California. MyRadar meteorologist @matthewcappucci.bsky.social has an update.

It’s peak hurricane season. 75 percent of all tropical cyclone activity occurs between August 20 and October 20. The season has been quiet for the U.S. so far, but that could change in mid-September. MyRadar meteorologist @matthewcappucci.bsky.social has an update for peak season.

Imagine getting hit by two tornadoes in just 41 minutes. That’s what happened near Bassfield, MS on March 15. During the high risk outbreak, overlapping tornado paths struck the same area—an intense and rare event caught on radar and maps. Meteorologist @matthewcappucci.bsky.social explains.

FOX35 just got hit by a tornado LIVE ON AIR! Tornado just passed Lake Mary and is heading toward Orlando’s Sanford International Airport!

A cross-country storm system is about to bring a tornado risk from Oklahoma all the way to Maryland: www.washingtonpost.com/weather/2025...

There is a slight chance of a bit of #thundersnow in NYC as a bit of elevated instability, or thunderstorm fuel at the atmosphere’s mid levels, works through. Plus the tall buildings are effective at focusing the diffuse lower positive charge found in snow clouds. @myradar.bsky.social

A thump of heavy snow will move along I-95 tomorrow morning between NYC and Boston. Why? Frontogenesis. Changing temperatures make a density ramp in the atmosphere that moisture rises up. That moisture comes back down as heavy snow. @myradar.bsky.social

Happy National Weatherperson’s Day! 🌀🌪️ Celebrating the MyRadar weather team and all the meteorologists and weather forecasters who keep us safe and informed, rain or shine!

An approaching slow pressure system could deposit a dangerous glaze of ice from Chicago to Columbus to Pittsburgh to Washington D.C. on Wednesday night or Thursday morning. Meteorologist @matthewcappucci.bsky.social takes an early look at the setup.

A hazardous glaze of freezing rain will fall from near Chicago to Washington D.C. overnight Wednesday into Thursday morning. Thunder may accompany the freezing rain. MyRadar meteorologist @matthewcappucci.bsky.social breaks down the icing hazard.

Same. Same. He brought a little tear to my eye. @matthewcappucci.bsky.social is a treasure.

Supercell outbreak in HAWAII! These rotating supercells are producing tornadic waterspouts. Tornadoes are possible, particularly near Kauai in the next few hours. Track the latest in the @myradar.bsky.social app.

My day is a little happier when @matthewcappucci.bsky.social does the weather in WAMU. Instead of endearing lightheartedness, this morning he showed empathy for a region struggling with a lot. "Be nice to your neighbors." Thank you for always projecting kindness, especially now.

WOW! The sting jet is about to hit Galway! See the pointy cloud? That’s the “stinger” as seen in @myradar.bsky.social! Shannon Airport has already gusted to 78 mph; Dublin has gusted to 60 mph. Galway should be ready for winds gusting 90-100 mph over the next few hours. #StormEowyn

Tonight will feature dangerously strong winds in Ireland, with gusts over 100 mph at the coastline as a "sting jet" descends to the ground. Much of the United Kingdom will face winds approaching hurricane force. Plan for damage and power outages. @myradar.bsky.social update coming.

A historic winter storm, complete with half a foot of snow in the Louisiana bayous, is shaping up for the Gulf Coast. Winter storm warnings span from the Mexican border to coastal Georgia. Snow will cover palm trees.🌴This is rare and exceptional.

PDS — or Particularly Dangerous Situation — red flag warning for Los Angeles and Ventura Counties. HUGE danger if any new fires crop up. This danger will continue, potentially with disastrous results, until widespread rain arrives in Southern California.

An absolutely historic winter storm is in the cards for the Gulf Coast! Winter storm warnings stretch from the Mexican border to the Florida Panhandle. Widespread 2-4” totals are likely, including in Houston and New Orleans . Panama City might even see an inch or two! WOW. ❄️

WOW! Winter storm for the Gulf Coast! Winter storm watches stretch from the Mexican border to Atlanta. Houston will see 2-4 inches of snow. So will New Orleans! Even snow on the TX Barriwr Islands! A rare, significant winter storm for places where palm trees are ubiquitous! 🌴

Los Angeles saw two winters with DOUBLE the normal rainfall. Then it stopped raining altogether. It’s a perfect recipe for extreme fires. Meteorologist @matthewcappucci.bsky.social breaks it down.

Meteorologist @matthewcappucci.bsky.social breaks down the BIGGEST mistake we make with wildfires.

The Palisades Fire burned more energy than the entire city of Los Angeles used in 2 years. That’s a LOT of heat release. Meteorologist @matthewcappucci.bsky.social explains. #wildfires #palisadesfire #california #losangeles #fire

The wheel covers of luxury cars are often made of aluminum. Aluminum melts at 1,221°F. Meteorologist @matthewcappucci.bsky.social believes the Palisades Fire burned at least 1,400° as it scorched neighborhoods — and likely much hotter. #fire #PalisadesFire #Eatonfire

WEATHER MANIPULATION!? Is it a thing!? Well… not really (at least the way the conspiracy theorists and my crazy neighbor think it is). I sat down Vice’s Shane Smith to discuss everything from hurricanes to HAARP to “chemtrails”: www.youtube.com/watch?v=Gz2S...

Three major wildfires around Los Angeles have killed at least two people and prompted evacuation orders for 70,000 more. Matthew Cappucci (@matthewcappucci.bsky.social), a meteorologist at MyRadar, explains what people near these fires can do to stay safe and healthy right now.

If you live in Los Angeles, shut your windows and turn off your vents to the outside — the air quality is hazardous. You can visualize air quality in the @myradar.bsky.social map. The bull’s eye of hazardous air is directly over the nation’s second-largest city.

With the app, we can see two scary things: • satellite-derived “hotspot” signatures that show the growing fire perimeters • weather radar depicting smoke plumes pouring 15,000 feet into the sky The Palisades Fire is up to about 3,000 acres; Eaton is roughly 2,300.

Here’s a recap of the country’s first big sprawling winter storm of the season: www.washingtonpost.com/weather/2025...

DMV folks – here's how much MORE snow is on the way this evening with the "backlash," or the cold air wraparound:

10 PM update – made a few very minor tweaks: - added a 9-12" contour for parts of the Delmarva - nudged the 6-10" contour a bit north into northern Howard/Anne Arundel Counties toward Baltimore - brought the 4-7" contour toward the Mason-Dixon Line – Kept southern edges as is

But wait – there's more! (Maybe.) There are indications that another storm system may develop over Texas on Thursday IF two disturbances "phase," or overlap synergistically. That would introduce the possibility of another East Coast storm. Low risk, but monitoring.

Icing is mainly south of I-66, but could be a concern for Interstate 81 and especially folks in West Virginia.

Keep in mind this will be heavy, wet snow... perfect for snowballs (cough cough @dcsnowball) that will be tough to shovel. (Heart attacks are common following big winter storms. Please take it easy if you're shoveling.)

While we've all been focused on the big synoptic-scale winter storm, let's not forget that the Tug Hill Plateau just got another 5 FEET of snow from the Lake Ontario lake-effect band. East Camden is up to 65 inches; 64 in Westernville, N.Y.

DMV gang – we're finally within range of the HRRR, or our highest-resolution computer model. I like the progression of this. I think D.C. gets almost entirely snow this time around, with only a brief mix or freezing rein during the early evening hours Monday.

DMV folks – here's my Saturday night SNOWSTORM update! Still looking like D.C. will be in the belt of heaviest snow... 5 to 10 inches, but localized 12 inches can't be ruled out across the DMV. We'll likely stay just north of the rain/snow line. Next to no adjustments:

Alrighty gang! We have winter storm warnings now in the pink. 6 to 8 inches of snow in Washington D.C., with up to a foot in the higher terrain of the Alleghenies. Some mixing and ice accretion in southwest Virginia.

NEW: Here’s my national forecast briefing for the storm… all the way from Kansas to Delaware. Lots of snow and ice with this… a messy mix for a lot of people: t.co/RxGNmI5Bai

HERE WE GO! Snowstorm time for the DMV. Here's my latest thinking. Snow begins Sunday night. It thumps during the morning, may briefly mix with sleet or freezing rain south of town, then becomes all snow again for everyone Monday evening with a surge of cold air on the back.

Thundersnow!? ⚡️ Today's environment is ripe for it! We've got some instability (thunderstorm fuel) and weather models are also simulating some lightning activity!

Alright DMV gang! Here it is – my first stab snow map for Monday's storm. ❄️ NOTE: A LOT can change. As for now, the heaviest looks to be between D.C. and the Mason-Dixon Line. In southwest portions of our area, I'm expecting mixing with some sleet/freezing rain. @myradar.bsky.social

This is going to be a BIG headache for a lot of people. Some folks see a foot of snow... others see a serious ice storm. We'll have a full update out this afternoon in the @MyRadarWX app.

MONDAY snow in the DMV: The chance of accumulating snow Sunday night into Monday night is INCREASING for the DMV. A low pressure system will pass nearby. If it passes just a bit south, we're on the cold side. About a 40% chance of plowable snowfall. Ironing out details.

FRIDAY snow in the DMV: A clipper system will drag a cold front east. Snow showers/squalls are likely along the front during the afternoon. A quick dusting is possible with reduced visibilities. Accumulations minor/negligible.

Increasing confidence in a Sunday/Monday ice storm across parts of Missouri and the Ozarks. Too early for specific impacts, but all three main weather models project 1 inch or more of glaze somewhere in the state. Specifics unknown, but a strong model signal for decent event.

DMV gang – we might get a surprise burst of a bit of snow on Friday afternoon. Probably no accumulation, but a clipper brings dropping temperatures and some rain flipping to snow. Minimal to no accumulation. Maybe a rumble of thunder with a bit of instability along the front.
