FRISCO — As if knowing that there are a couple of drab months ahead, Colorado’s aspen trees burst into full color this week in a magical transformation that never fails to amaze. In some cases, entire hillsides change over in just a day or two; in other areas, the shift takes a little longer, but the end result is the same. And with relatively calm and sunny weather forecast for the next few days, the show should continue, at least until a big windstorm or the first real snowfall of autumn (at valley elevations) starts to sweep the leaves off the trees.

Down-scaled climate modeling suggests sugar maples will probably persist for a while
FRISCO — New downscaled climate models for Vermont suggest that the state will probably be able to produce maple syrup in the coming decades, but the distribution of best habitat for sugar maples will shift, and average temperatures will increase by 5 degrees Fahrenheit by 2050.
By late in the century, Vermont’s average temperature will increase by 8 degrees Fahrenheit, adding 43 days to the growing season — and 10 additional days with temps above 90 degrees in Burlington, while snowfall is likely decrease by 50 percent at six major ski resorts, according to a team of scientists who recently published states-specific projections in the Journal of Applied Meteorology and Climatology.

Tis the season … for fall colors!
Fall colors unfolding along the Tenderfoot Trail in Dillon, Colorado.
FRISCO — One of the things I like best about autumn photography is the strong contrasts in light. That may not always be the best situation for capturing all the nuances in a scene, but it does help create drama and tension, some of the key ingredients to a captivating image. Don’t wait for the “peak” of the fall color season. Start your hunt now, because a sudden freeze after a hard rainstorm could put an end to the display.

Can ya feel it?
FRISCO — Right on time, Mother Nature is changing wardrobe, from the bright greens of summer to the even more dazzling array of golds, reds and yellows that mark the transition of seasons in the High Country. Even the light takes on a different quality as the sun’s rays have to make it through a thicker slice of the Earth’s atmosphere. This year’s aspen show looks to peak around late September and early October, but some areas are already changing fast in the high country. Don’t miss the show! Continue reading

Researchers starting to take nuanced look at chemical composition of aerosols
FRISCO —Scientists have long known that tiny grains of airborne dust are key players in the formation of rain and snow, driving precipitation patterns across the drought-stricken western U.S. and other areas.
New research suggests that the exact chemical make-up of that dust, including microbes found in it, is the key to how much rain and snow falls from clouds. The information could help better predict rain events, as well as explain how air pollution from a variety of sources influences regional climate in general.
“We’ve learned that not all of the particles in the air at high altitudes have the same influence on clouds. We’re starting to think that these differences contribute to how rain gets distributed,” said Dr. Kim Prather, who presented her findings at the 248th National Meeting & Exposition of the American Chemical Society last week in San Francisco.

Early morning cloudscape pano near Frisco, Colorado.
FRISCO — For a few weeks every summer, Colorado’s weather pattern experiences a seasonal shift that gives us a taste of the tropics. As big high pressure areas move around, moisture often streams into our mountains from the south, keeping the air moist and temperatures relatively warm at night, since the clouds, or even just the moist air, act as a blanket and prevent the day’s warmth from radiating back into space at night. It may be hard to believe, given how much snow we get in the middle of winter, but our monsoon season is actually the wettest time of year in Colorado. And, of course, it’s one of the best times to snap pictures of dramatic cloudscapes. Continue reading

Springtime in the Rockies …
Blades of grass in roadside puddle catch the spring snow in Frisco, Colorado.
Even though it feels a bit weird every time it happens, May snow is not really all that unusual in high-elevation mountain climates. In fact, when I look back through the Summit Voice archives for the past few years, I see that there have been at least one or two May snowstorms almost every year, with 2012 as a recent notable exception. The wet snow that falls in May sticks to everything, and the opening buds on many of the trees also help provide platforms that catch the flakes so even just a couple of inches can look pretty impressive. And it’s always a good time to get out and enjoy the fluff because by this time of year, each snowfall could easily be the last for the next 5 months or so.
