Team leaders


Jason Samenow – Chief meteorologist, weather editor

Jason Samenow is the Washington Post’s Weather Editor. He founded CapitalWeather.com in early 2004, the first professional weather blog on the Internet which was absorbed by the Post in 2008 and became the Capital Weather Gang, which he has since led. A native Washingtonian, Jason Samenow has been a weather enthusiast since age 10 (1987). Before graduating from high school, he interned for NBC4 chief meteorologist Bob Ryan. At the University of Virginia, he earned a degree in environmental science, focusing in atmospheric science. He went on to earn a master’s degree in atmospheric science at the University of Wisconsin-Madison in 2000.

From 2000 to September 2010, he worked as a climate change science analyst for the federal government, monitoring, analyzing and communicating the science of climate change. Jason is a past chairman of the D.C. Chapter of the American Meteorological Society, and a Weather and Society Integrated Studies Fellow. He also holds the National Weather Association Digital Seal of Approval. Jason lives with his wife and two children in Washington, D.C.


Andrew Freedman – Deputy weather editor

Andrew Freedman is an editor for Capital Weather Gang at The Washington Post. He has long covered science research and policy, with a focus on climate change, extreme weather and the environment. He was among the first reporters to popularize the term “polar vortex” during the infamous East Coast winter of 2013 to 2014. He joined The Post in 2019, having worked as an editor and reporter for Axios, Mashable, Climate Central and other publications.


Matthew Cappucci – Meteorologist

Matthew Cappucci is a meteorologist for Capital Weather Gang. He earned a B.A. in atmospheric sciences from Harvard University in 2019, and has contributed to The Washington Post since he was 18. When he was 14, Cappucci became the youngest-ever presenter at the American Meteorological Society, where he delivered an abstract on “outflow boundary-related waterspouts.” When not in the office, Cappucci can be found staring at the sky, hopping aboard an airplane or chasing the next storm. Follow Matthew on Twitter, @MatthewCappucci.


Dan Stillman – Lead meteorologist

Weather and Washington are two of Dan Stillman’s greatest passions. The excitement of snow days and two-hour delays are what first got him hooked on tracking lows and highs across the country. After graduating from Walt Whitman High School in Bethesda, Md., he went on to earn a B.S. in atmospheric, oceanic and space sciences from the University of Michigan (and like most Michigan grads is still obsessed with everything Wolverines), and a master’s degree in meteorology from Texas A&M University. He also has a background in journalism and enjoys combining his love for weather with his writing skills. Dan has been published in the Washington Post, Weatherwise Magazine and elsewhere, and served as editor for NBC4 chief meteorologist Bob Ryan’s 2005 Almanac and Guide for the Weatherwise. He is also a Weather and Society Integrated Studies Fellow.


Ian Livingston – Information lead, photographer/forecaster

Ian Livingston (on Twitter) has lived in Washington since early 2006, having moved to the area shortly after graduating from the University of Connecticut. While residing in New England, Ian was trained as a SKYWARN spotter, and his self-education in meteorology has been ongoing since he first witnessed snow at his childhood home in the southern California desert. During college, he created a website focused on forecasting upcoming weather conditions on and around campus. Ian has also co-developed several premier weather discussion forums, the most recent being AmericanWx.com, which replaced the Eastern U.S. Weather Forums (founded ’04) in late 2010. Photography became a natural offshoot of his love for weather, and he has acquired a greater knowledge of both — and how they intersect — while out in the field. In 2010, he wrote, with Kevin Ambrose, “Snowmageddon: Washington’s Record-breaking Winter of 2009-10,” a photographic and meteorological recap of D.C.’s snowiest winter.


A. Camden Walker – Engagement lead, meteorologist

As a youngster, A. Camden Walker found looking upward at the atmosphere to be an enthralling experience. It hasn’t stopped. From striving to learn all of the cloud types, reading almanacs, and earning the weather merit badge, today he wants to engage further with an audience curious about how weather influences them and why the atmosphere behaves as it does. Weather is a daily experience for almost everyone and he loves the sociological and psychological aspects to meteorology. From UV rays, to snowstorms, to tropical cyclogenesis (the development and strengthening of tropical cyclones) he does not want to stop learning. He continues to dabble in nature photography especially when travelling abroad. Camden has a bachelor’s in atmospheric science from the University of Virginia. To be a better educator, he earned a Multimedia Journalism Certificate from the University of Maryland (2015). Camden previously spent time in Atlanta interning and going through on-air training at The Weather Channel. He now has long lived in the District, because the city is in his family’s blood and it continues to resonate with him. He’ll also admit to the city’s perfect positioning on the North American continent, giving it an exciting mix of mid-latitude weather!

Daily forecasters


Brian Jackson – Meteorologist (Sunday)

Brian Jackson was initiated into the Gang in 2008. A transplant to the area, he was born and raised in Upstate New York where he spent many of his formative years shoveling out from lake effect snows. Those snows, and a freak ice storm in 1991, helped to jumpstart his interest in the weather. Two significant, possibly related, events took place for Brian in 2000: he headed off to attend college at the State University of New York at Oneonta, and his father purchased a snowblower. After receiving bachelor of science in meteorology in 2004, he decided a change in climate was necessary and enrolled in the graduate program at Florida State University, where he received a masters in meteorology in 2007. Brian lives and plays with his wife and daughter in Howard County, Md., where he enjoys taking advantage of the area’s running trails, playing soccer, and exploring the region’s growing craft beer culture — though not all at once — while waiting for the next model runs to come in.


Greg Porter – Meteorologist (Weekend P.M.-updates)

Greg Porter has been a weather nerd pretty much from birth. Growing up in Boston provided Greg with a litany of interesting weather to solidify his love of the atmosphere. As a child, Greg started a weather watchers group with neighborhood children, albeit on a small dead end street. He still monitors the weather station he installed on the roof of his parents house. Greg’s passion for meteorology continued to grow throughout the years, leading him to University of Massachusetts-Lowell where he earned a Bachelor of Science degree in meteorology followed by a Master of Science degree in meteorology from the University of Maryland. Regardless of how many degrees or experience Greg receives in the field of meteorology, his father will always insist his own snowfall forecast is correct. Follow Greg on Twitter.


Matt Rogers – Meteorologist (Tuesday)

Matt Rogers is a meteorologist and Washington, D.C. (Petworth) resident. He is President and co-founder of the Commodity Weather Group in Bethesda, Md., which focuses on weather risks for the energy and agriculture sectors. Matt was previously the Director of Weather for MDA EarthSat Weather in Rockville, Md., and he has consulted for the energy sector for over 20 years. Matt earned a B.S. degree in meteorology from Penn State University (1994) and an MBA from George Mason University (2001). Like most meteorologists, his passion for weather started extremely early in life and has never let go.


David Streit – Meteorologist (Thursday)

David Streit is a 1978 graduate of the University of Nebraska with a Bachelor of Science in Earth and Atmospheric Sciences and a 1981 graduate of the University of Wisconsin with a Master of Science in Meteorology.

Occasional contributors


Justin Grieser – Science writer

Justin Grieser is a D.C. area native whose fascination with weather and climate patterns has largely been a self-taught hobby. Born and raised in Alexandria, Va., he received his bachelor’s degree from the University of Virginia with a double major in Linguistics and French. Justin attributes his interest in meteorology to extensive childhood travels throughout Europe and North America, during which he noticed sun angle differences depending on his current latitude. From an early age, he enjoyed escaping D.C.’s oppressive summer heat during family vacations to his mother’s homeland in the Austrian Alps. As a snow enthusiast, Justin was disappointed to miss D.C.’s historic 2009-2010 winter while teaching English in France. Yet he avidly followed the Capital Weather Gang and its extensive coverage of Snowmageddon while living abroad. In addition to his self-taught background in meteorology, Justin has completed coursework on climate systems and severe weather at George Mason University. Fluent in German, French, and several other languages, Justin aspires to combine his passion for both the natural and social sciences in a policy-oriented line of work.


John Hopewell – Earth science specialist and writer

John has been fascinated by the weather for as long as he can remember. In the third grade he convinced his parents to get him a subscription to USA Today just for the colorful full-page weather spreads. He grew up in Northern Virginia, but as an avid outdoorsman he was drawn out west for college. Skiing the “cold smoke,” fishing pristine rivers, and hiking in and around Yellowstone made Montana State University the perfect choice. After earning a B.S. in Physical Geography, he spent a winter as a weather observer in training at the Mount Washington Observatory in New Hampshire. That led to a three year stint with the National Center for Atmospheric Research (NCAR), at the Research Applications lab in Boulder, Colorado. In 2002, he moved to the Netherlands to pursue his Master’s focusing on Environment and Development at the University of Amsterdam. He teaches Earth Science in Fairfax County. John is a SKYWARN spotter and personal forecaster for family and friends.


Joe Kunches – Space weather expert

Joe became interested in space when, as a grade-schooler in St. Charles Illinois, he heard NASA’s John “Shorty” Powers’ describe the drama of the Mercury launches over the school PA system. His sights were set on becoming an astronaut. After receiving a degree in Aerospace Engineering from the University of Notre Dame, it became clear that less than perfect vision would squash the astronaut dream. But in the SKYLAB era, he was fortunate, while a NOAA Corps officer, to work as a space weather forecaster at Johnson Space Center, briefing the scientists on the space weather they wished to observe. Following an M.B.S. from the University of Colorado-Boulder, he continued a career in space weather, first as the lead forecaster and then the Chief of Operations at NOAA’s Space Weather Prediction Center, spanning over 5 solar cycles. He lives with his wife Linda in Niwot, Colorado.


Brian McNoldy – Hurricane expert

Brian McNoldy was born and raised in Reading, Pa., where his interest in weather was sparked at age 7 by the big Nor’easter snowstorm of February 1983, and then further piqued by Hurricane Gloria in September 1985. He earned his B.A. in physics and astronomy from Lycoming College in Williamsport, Pa. in 1998, held an internship at NASA Goddard in Greenbelt, Md. in the summer of 1997, then went on to graduate school where he completed his M.S. in atmospheric science at Colorado State University (CSU) in Fort Collins, Co. in 2001. He spent the next ten years working at CSU’s Department of Atmospheric Science conducting research on a multitude of tropical cyclone topics. Brian has maintained his own blog on tropical Atlantic activity since 1996, and was selected as one of four hurricane experts for the New York Times blog from 2007-2010. In 2012, Brian took a position at the University of Miami’s world-renowned Rosenstiel School of Marine and Atmospheric Science (RSMAS) to continue his career in tropical cyclone research. His website hosted at RSMAS is also quite popular during hurricane season.

Bryan’s book, My Hurricane Andrew Story was released in 2017.


Matt Ross – Seasonal forecaster

Matt Ross has been interested in weather since early childhood, including a specific fascination with snowstorms and extreme weather events. Although he passed on a career as a meteorologist, his enthusiasm for both weather and statistics, particularly related to the D.C. area’s local climate, continues to strengthen as he gets older. Frustrated with the region’s lack of snow, Matt has been known to chase after the white stuff, including recent trips to northern New England and the Tug Hill region of New York during major snow events. Of particular interest to Matt is the study of analogs, or past weather data as a means of predicting long-range seasonal patterns.
