At BoulderCAST, our meteorologists understand the intricacies of Front Range Colorado and the direct impact they impart on our weather. From the mouth of Boulder Canyon, to the towns of Broomfield and Lakewood out on the plains, to the 14,259-foot summit of Longs Peak, we regularly provide the most accurate forecasts and weather information for Boulder, the Denver Metro area, and Colorado beyond.




Ben Castellani, M.S.   After growing up in a a tiny town in rural western Pennsylvania, Ben pursued a bachelor’s degree in Meteorology from Penn State University in 2010 and later a master’s from the University of Colorado in Atmospheric Science in 2014. He previously worked at NOAA on a project that involved living in Greenland for nearly a year, taking ground-breaking measurements of clouds and snowfall at temperatures as cold as -80 degrees Fahrenheit! He has been providing forecasts for friends, family, and colleagues around the world for years, but particularly enjoys the added topographic challenges of forecasting Denver’s winter storms.

Ben currently works at Harris Geospatial Solutions in Boulder, striving to make the scientific programming language IDL better every day.




Andy Kren, Ph.D.   Andy grew up in Missouri and attended St. Louis University, receiving his bachelor’s and his master’s in Meteorology in 2009, and in the process, developed the Mesonet across his home-state. He then got his Ph.D. in Atmospheric Science from the University of Colorado in 2015 with an emphasis on sun-climate connections. Andy has a zeal for weather forecasting, having provided daily weather forecasts for a radio station in St. Louis since 2007 and was a student volunteer at the National Weather Service in Boulder in recent years.

Andy now works as an atmospheric scientist at NOAA in Boulder aiming to improve weather forecasts through the use of UAVs.




Matthew Steiner, M.S.   Growing up in the suburbs of Mobile, Alabama, Matt has lived through many strong hurricanes, including Katrina. He attended the University of South Alabama and received a bachelor’s degree in Meteorology. It was there he became interested in weather forecasting. Matt worked for Alert Weather Services in Lafayette, Louisiana for nearly two years, forecasting weather and sea conditions for offshore clients. Matt’s passion for hurricanes easily makes him our tropical expert.

In 2013, he shifted gears in his career and moved to Colorado to begin graduate school at CU-Boulder. He currently researches orographic precipitation along the Colorado Front Range and hopes to complete his Ph.D. in the next few years.




Josh Aikins, M.S.   Josh received a bachelor’s degree in Meteorology from Penn State in 2012, where he was also a forecaster for the university’s weather service. He is now a Ph.D. student at the University of Colorado in Boulder, with studies focused around cloud microphysics and dynamics within winter orographic storms. He has a passion for precipitation research and forecasting, as well as mountain meteorology. Like most of our team, Josh loves skiing and hiking in Colorado’s High Country where he can witness this weather first-hand. In his spare time, Josh captures stunning time-lapses of weather and aerial drone footage

Josh currently works as a graduate research assistant at NOAA’s Earth System Research Lab in Boulder, with hopes to finish his Ph.D. in the not-so-distant future.




Keah Schuenemann, Ph.D   Keah was inspired to explore meteorology after witnessing an F5 tornado while growing up in Wisconsin.  She earned her bachelor’s degree in Atmospheric and Oceanic Science at the University of Wisconsin in 2004 where her interests expanded to climate change.  She then got her master’s in 2006 and Ph.D. in Atmospheric and Oceanic Science from the University of Colorado in 2008 by creating a climatology of weather patterns and precipitation near Greenland.  For Keah, snow evokes nostalgia for home, but she tries to not let that cloud her judgment while forecasting Front Range snowstorms.  She enjoys finding new ways to explain complex meteorology and climate change concepts to her students and the public.

Nowadays, Keah is an associate professor of meteorology at Metropolitan State University of Denver where she teaches climate change, dynamic meteorology, and advanced synoptic meteorology to undergraduates.
