Team leaders
Jason Samenow – Chief meteorologist
Jason Samenow is Capital Weather's chief meteorologist. He founded CapitalWeather.com in early 2004, one of the first professional weather blogs on the Internet. It was absorbed by The Washington Post in 2008, and became the Capital Weather Gang, which Samenow led for 18 years.
A native Washingtonian, 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 at Madison in 2000.
From 2000 to September 2010, he worked as a climate change science analyst for the U.S. Environmental Protection Agency, monitoring, analyzing and communicating the science of climate change. After that, he became The Washington Post’s weather editor and steered its local, national and international meteorological coverage until October 2024.
Samenow 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 Certified Digital Meteorologist certification from the American Meteorological Society and the National Weather Association Digital Seal of Approval. He lives with his wife and two children in D.C.
Dan Stillman — Lead meteorologist
Weather and Washington are two of Dan Stillman’s (@stillmand) 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 BS 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. Stillman 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, forecaster
Ian Livingston (@islivingston) has resided in Washington since early 2006, having moved to the area shortly after finishing college in New England.
While residing in Connecticut, Livingston saw his first nor’easter and was first trained as an National Weather Service spotter. His education in meteorology has been ongoing since first marveling at snow falling on his childhood home in the Southern California desert. Focusing on data analysis and extreme weather, he has been forecasting rain, wintry mix and sun in the D.C. region since 2008.
He also helped develop and run several successful weather-based websites over the past few decades, including ustornadoes.com, where he remains active.
A. Camden Walker — Engagement lead, meteorologist
By age 8, A. Camden Walker (@camdenwalker) moved from looking groundward at dinosaur fossils to looking upward at the atmosphere. It hasn’t stopped since overnight microburst damage galvanized weather into an enthralling interest.
Walker spent time in Atlanta at the Weather Channel where he turned an internship into studio assistant and on-air program graduate. He’s been with Capital Weather since 2005 where his multimodal communication passion has grown from written articles and associated comments (that continue on our CWG.live blog), to audio on WAMU radio, Alexa, and podcast excerpts, then live video in our weekly Sunday Sunset Q&As.
With decades in the D.C. area, he appreciates the city’s perfect positioning on the North American continent, giving it an exciting mix of mid-latitude weather that brings a welcome challenge. Find him frequently hiking trails in Maine and Maritime provinces.
Walker has a bachelor’s degree in atmospheric science from the University of Virginia and multimedia journalism master’s certificate from the University of Maryland. He is a lifetime member of the National Weather Association and continues weather app research in probabilistic XR/AR forecasts (formerly WeathAR) and intersections with GenAI among other emerging technologies.

Jeffrey Halverson — Severe weather expert
Jeff Halverson grew up in the Mid-Atlantic region and became attuned to the vagaries of our weather and climate at a very early age.
He received his PhD in environmental science at the University of Virginia in 1994, then assumed a postdoc under venerable weather scientist Joanne Simpson at NASA’s Goddard Space Flight Center. He is a professor at University of Maryland Baltimore County (UMBC) where he teaches courses on meteorology, severe storms, natural hazards and climate change. He and his team of graduate students investigate severe storms, including hurricanes, derechos and societal aspects of severe storm warnings. Halverson has written nearly 50 scientific publications and has appeared in science documentaries aired by NOVA, National Geographic and the Discovery Channel. He has been a columnist and assistant editor for Weatherwise Magazine since 2002. Halverson’s favorite type of storm is a hurricane undergoing extratropical transition in the Mid-Atlantic … but he also loves a big snowstorm.
Wes Junker — Winter weather expert

Occasional contributors
Justin Grieser — Writer
Justin Grieser (@justingrieser) 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. In addition to his self-taught background in meteorology, Grieser has completed coursework on climate systems and severe weather at George Mason University.

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, Ross has been known to chase after the white stuff, including trips to northern New England and the Tug Hill region of New York during major snow events. Of particular interest to him is the study of analogues, or past weather data as a means of predicting long-range seasonal patterns.
