Jefferson recorded 76°F in Philadelphia on July 4, 1776. Washington, D.C., reached a record 103°F on July 4, 2026. What about the years in between? This infographic provides the answer, showing the highest temp recorded on July 4 each year at our nation's capital—wherever that was at the time. 🇺🇸🌡️

☔ How did weather forecasting influence D-Day? AMS Headlines answers the audience questions we didn't have time to cover during our Forecasting D-Day webinar—from wave forecasts and forecasting disagreements to German weather intelligence and the meteorologists behind Operation Overlord.

I'm quoted in today's @usatoday.com (both in print and online) about the critical role weather played in planning for D-Day and the challenges forecasters faced. Included in the discussion is a 2020 Bulletin of the @ametsoc.org article suggesting that forecasters were "right for the wrong reason."

🎬 Pressure is out in theaters today! Earlier this week, we hosted the film's director and a panel of experts to explore the meteorology that shaped one of the most consequential military decisions in modern history. Learn more and watch the webinar recording here: https://bit.ly/4dMqtvW

In the new film PRESSURE, Andrew Scott plays James Stagg, the chief meteorological advisor to Eisenhower for D-Day. This is not the first time, however, that an actor has played the meteorologist on the big or small screen. Watch my video to learn more: youtu.be/rnPaj3CthJY

The @ametsoc.org has posted yesterday’s webinar on the science behind the new film PRESSURE, which I had the pleasure of moderating. Director Anthony Maras joined the panel for a great discussion. Hope you enjoy the conversation—and the film!

ICYMI on @todayshow.com Craig Melvin referred to the new film Pressure as a "love letter to meteorology." 🌦️🌪️☔❄️ Also great to see @kathrynprociv.bsky.social and her colleagues at @nbcnews.com (pictured at 05:17) at a private screening of the film with Al Roker. www.youtube.com/watch?v=1P-r...

"When Mount Saint Helens erupted on the morning of May 18, 1980, it created an environmental disaster of cataclysmic proportions unlike any that had been seen in the United States." My Retrospect column about #MountStHelens for Weatherwise Magazine from 2014: www.tandfonline.com/doi/full/10....

Join me tomorrow at 7:00 p.m. ET for the @ametsoc.org webinar "E Pluribus Praevisio: Collaboration and the Rise of the Planetary Commons." I will be discussing the history of international collaboration in meteorology from colonial times to the mid-20th century. Register at: bit.ly/4c0y7TN

I'm excited to moderate this webinar about the upcoming film PRESSURE! The panelists will include weather historian and @colbycollege.bsky.social professor emeritus Jim Fleming, @rmets.org fellow Jim Galvin, former @metoffice.gov.uk chief forecaster Martin Young, and filmmaker Anthony Maras!

Joanne Simpson became the first woman in the U.S. to earn a Ph.D. in meteorology in 1949. Her pioneering research on clouds, hurricanes, tropical convection, and satellite meteorology helped transform atmospheric science. #NationalMeteorologistsDay 🌩️ #Meteorology #WomenInSTEM

📅 Celebrating #NationalMeteorologistsDay 🌪️ After Hiroshima and Nagasaki, Ted Fujita studied patterns of destruction left behind by catastrophe. He later conducted groundbreaking research into tornadoes, downbursts, and severe storm damage. #Meteorology #SevereWeather #Tornado

Today is National Meteorologists Day. Embrace the Science. Honor the Experts. #NationalMeteorologistsDay

Thanks to fellow meteorologists @graceyweather.bsky.social and Kerrin Jeromin for promoting National Meteorologists Day (May 9) in their Weekly Weather Brief! Their discussion of it begins at 8:00 into the video. Check it out! lnkd.in/epuTxKvJ #NationalMeteorologistsDay

Weather forecasting touches nearly every sector of society—helping protect lives, support the economy, and keep communities informed. Celebrate National Meteorologists Day on May 9 and help recognize the people behind the forecast. #NationalMeteorologistsDay #Meteorology #Weather #Science #STEM

A perspective piece I wrote for @ametsoc.org on National Meteorologists Day and why it's needed... headlines.ametsoc.org/2026/05/08/i...

During WWII, women stepped into Weather Bureau roles as men left for military service. Pioneers like Virginia Tredinnick helped open doors for future generations of atmospheric scientists. www.nationalmeteorologistsday.com #NationalMeteorologistsDay 🌩️ #WomenInSTEM #Meteorology #Weather

Tomorrow is National Meteorologists Day. Take a moment to recognize the scientists behind the forecast. www.nationalmeteorologistsday.com #NationalMeteorologistsDay

Pioneers like William Hallet Greene helped break barriers in meteorology—but there’s still more progress to be made. May 9 is National Meteorologists Day—a day to celebrate the scientists behind the forecast and the ongoing effort to build a stronger, more inclusive future for meteorology.

Meteorologists work in: aviation • research • military • emergency management • and more Not just on TV. www.nationalmeteorologistsday.com #NationalMeteorologistsDay

May 9 honors James Pollard Espy, America's first official meteorologist. 📖 Pioneer of American meteorology 🌩 Early storm theory A legacy that still shapes forecasting today. www.nationalmeteorologistsday.com #NationalMeteorologistsDay

Weather affects everything. Safety. Travel. Agriculture. Energy. Meteorologists help communities prepare—every single day. #NationalMeteorologistsDay

Maybe meteorologists weren’t on the set of Star Wars—but if they were, they’d be providing critical decision support behind the scenes. Because when it’s time to roll, “Never tell me the odds” isn’t an option. May 4 → #MayThe4thBeWithYou #StarWarsDay May 9 → #NationalMeteorologistsDay

Forecasting = physics + data + modeling. Not guesswork. #NationalMeteorologistsDay

A meteorologist isn’t just someone who talks about the weather. They’re scientists. As we approach National Meteorologists Day on May 9, it’s worth recognizing the breadth of the profession and the depth of expertise behind something we rely on every day. #NationalMeteorologistsDay

Weather impacts every aspect of our lives—from safety to the economy. Behind every forecast is science, training, and expertise. Join us in celebrating National Meteorologists Day on May 9. #NationalMeteorologistsDay

Meteorologists do more than deliver forecasts. That’s why I’m proposing National Meteorologists Day on May 9—the birthday of James Pollard Espy (1785 – 1860)—a pioneer of American meteorology. Learn more + resources: NationalMeteorologistsDay.com #NationalMeteorologistsDay

My latest Retrospect covers the Jasper #tornado of 1927—photographed by 16-year-old Lucille Handberg who went on to attend the State Teachers College in St. Cloud (now @stcloudstate.bsky.social my alma mater) making her the 1st #stormchaser to attend that school: www.tandfonline.com/eprint/CD8K2...

Thanks to @ametsoc.org for featuring me in the April issue of BAMS with a quote from my Clear Skies Ahead podcast interview on how I came to write my biography of Cleveland Abbe. Listen to the podcast at: blubrry.com/clear_skies_... Get a copy of my book at: press.uchicago.edu/ucp/books/bo...

For anyone interested in reading my Retrospect column about the St. Louis tornado of 1896–mentioned in the Forbes piece by Dr. Shepherd–this link should take you to the full text: www.tandfonline.com/eprint/THT9Q...

A great writeup on why we need a well-funded and fully-staffed NWS. Without weather radars, models, and warnings, we might as well be back in 1896, when a devastating tornado on May 27 cut a 10-mile path of destruction through the heart of St. Louis, killing 255 people and injuring 1,000 others.

Confused about the difference between a severe weather watch vs a warning? Just think of it in terms of... tacos! 🌮🌪🌩

On this anniversary of the sinking of #Titanic, I spoke with @wgem.com in Quincy, Illinois, about the role weather and other environmental factors played in the disaster on that clear, calm, and bitterly cold night in the North Atlantic 113 years ago. www.wgem.com/2025/04/15/t...

Inspired by my earlier thoughts today, a childhood bee sting, and something a colleague Paul Walsh said, my weekend thoughts in Forbes dot com offers advice for aspiring scientists right now. And perhaps for seasoned ones too. www.forbes.com/sites/marsha...

Can lessons from weather preparedness be applied to the coming storm that is the caregiving crisis facing America? Find out as I join @paula_span and @BCG's Suchi Sastri in this episode of American Metamorphosis from @atlanticrethink... x.com/TheAtlantic/st…

Robert C. Abbe, great-grandson of pioneering #meteorologist Cleveland Abbe and grandson of Cleveland Abbe Jr., recently donated letters, documents and other material from his grandfather and great-grandfather to @librarycongress to be part of its Cleveland Abbe Papers collection.

Three great-grandsons of Cleveland Abbe at the unveiling of his portrait at @artsclubdc, located at 2017 I St. NW in #WashingtonDC, his home from 1877-1907. “For those thirty years he gave character to the house,” Cleveland's son Truman wrote. Now his portrait hangs in its foyer.

Three generations of descendants of Cleveland Abbe at the recent event honoring him at his former house at 2017 I St. NW in #WashingtonDC, now home to @artsclubdc.

I noticed that @dcpl had several copies of Too Near for Dreams in its collection, but not at the flagship Martin Luther King Jr. Memorial Library location, which is just two blocks from where I live, so I donated a copy. Check it out—literally! bit.ly/3PQAif6

#OTD 50 years ago, Rapid City was devastated by the second-deadliest flash #flood in U.S. history, killing 238 people and injuring more than 3,000 others. This @USGS map shows the extent of the flooding along with photos of damage. Full version: pubs.usgs.gov/ha/511/plate-1…

Congrats to Ken Graham on his selection as @NWSDirector! On a historical note, Ken is the first head of @NWS to have spent his entire career in the nation's weather service since Willis Gregg, who served as chief of the Weather Bureau from 1934-1938.

I love they way they presented the wind "feathers" back then. They may not be as sophisticated the modern-day wind barbs used on station model plots, but they do have a certain retro look to them.💨 t.co/UeddFeF5mf
