As recently as 10 years ago, Boulder weather reporting was reliable and precise. While Boulder Valley has always presented a prediction challenge, even in Boulder the question was more along the lines of demarcation of different areas of moisture, temperature and wind. BUT since then, weather prediction has been poor. Rain might come as predicted, […]

Boulder has an ideal climate and geography for the formation of Virga. Virga is a captivating weather phenomenon in Boulder and elsewhere, that presents itself as streaks or wisps descending from a cloud but evaporates or sublimates before reaching the ground. This meteorological marvel occurs when precipitation falls from a cloud into a layer of […]

Living in Boulder, Colorado means being no stranger to extreme weather, but one phenomenon stands out as particularly awe-inspiring: thunder snow. This rare and dramatic event combines the intensity of a thunderstorm with the serene beauty of falling snow, creating a spectacle that captivates all who witness it. Understanding the science and experiencing the wonder […]

  Fact or Fancy? Avalanche or Anticipation? I think we get a PILE of Precipitation!  I am not licensed to be a meteorologist or any other type of ologist. As a Boulderite and a Buff,  I can’t be a tourist, so I am by definition a fool. No shockers there. Only fools and tourist predict […]

  Weak Fern Wall. ?                     pic Lenny Lensworth Frieling Boulder Blizzard Imminent? Perhaps not. What’s missing? For one, a nicely defined long “fern wall.” This hot dog shaped cloud runs North and South between the Front Range and the Continental Divide. To me, fhis possible fern wall, to this fool’s eyes, looks weak and disorganized. […]

  As always, the lighting on the mountains  and the lighting on clouds is never the same. If we insist on being technical, this is a sunrise, not a sunset. BUT I love the image. And if a reader were to see this in the morning, Friday morning for example, then we’d have the sun […]

Sunday Sunrise Spectacular! The Boulder sunrise red can take over the sky! I suspect it is a physiological-sociological phenomenon. If sunrises were not often beautiful, uplifting, inspiring, and colorful, as well as accompanied by coffee, would we ever get out of bed in the morning? Of course we would! But it would not be as […]

Boulder has had the honor and privilege of being watched over by the majesty of Longs Peak. Towering 14,259 feet,  4350 meters above sea level, and almost 10,000 feet, 3000 meters above Boulder. We’re mile-high, with the 5280 topo line going through our back yard, right where our Buddha stands. The top of Longs, which […]

Boulder, Colorado, has long been a world-center for computers, hosting the world’s most powerful, fastest computers right down the road from us. NCAR has had a long list, since predicting weather and monitoring climate change requires massive computing power. The most massive on earth much of the time. CHATgpt and Siri and even Alexa are […]
