Winding down …

Alpenglow up close.
FRISCO —Though the equinox is still a few weeks away, the last day of February marks the end of the meteorological winter, so you might see your local TV forecaster talking about spring. Here in the heart of the Colorado Rockies, this may well go down in history as one of the mildest winters on record, as both low and high temperatures ran well above average for weeks on end. We still had our share of snow and frost, but if these past few months are a harbinger of global warming, then we’re probably in trouble. Wouldn’t it be sad if our kids and grandkids couldn’t enjoy the gorgeous frozen landscapes shown in this set?

Study tracks increased thunderstorm formation over Atlanta
A classic anvil-headed cumulunimbus cloud drops showers just east of the Continental Divide near Grays and Torreys Peak in Colorado.
FRISCO — Along with steadily raising global temperatures in the long-term, human-caused changes in land cover can affect day-to-day weather, including the formation of thunderstorms.
Specifically, urban areas appear to help trigger the formation of thunderstorms, possibly due to an increased concentration of aerosols, according to new research published in the Quarterly Journal of the Royal Meteorological Society. Continue reading

Annual conference includes all-star climate science speakers
November’s above-average temperatures kept Earth on track to record its warmest year on record. Learn more from this year’s Glen Gerberg Weather and Cimate Summit.
FRISCO — This year’s Glen Gerberg Weather and Climate Summit in Breckenridge once again features some notable climate scientists, including James Balog, who has documented the disappearance of Arctic sea ice, and Dr. Richard Knabb, director of the National Hurricane Center. As in past years, the sessions will be webcast live, enabling the general public to listen and even to ask questions online. Continue reading

October storm clears the Tenmile Range near Frisco, Colorado
FRISCO — Is there anything better than the sight of a storm clearing over a big mountain range, with lifting clouds and broken bits of sunshine streaming in? After a string of warm and sunny days, a quick storm passed through Summit County Oct. 20, leaving the higher elevations frosted with some new snow. As always, the clearing storm created stunning vistas of mountains and clouds.

Severe dust storms spawned even more widespread drought, research shows
FRISCO — With all the recent talk of looming megadroughts, the 1934 peak of the Dust Bowl era still remains the most severe and widespread drought in North America during the past 1,000 years, climate scientists say.
Based on tree-ring studies and other physical records, the only other comparable event was way back in the 1500s.
The extent of the 1934 drought was approximately seven times larger than droughts of comparable intensity that struck North America between 1000 A.D. and 2005, and was caused in part by an atmospheric phenomenon that may have also led to the current drought in California, according to a new study.

A couple of cool spots, and big hot pocket out West in Sept. 2014.
NCDC says it was the 26th-warmest September on record
FRISCO — While 2014 is likely to end up as one of the warmest years on record for the planet, the U.S. hasn’t been quite so warm. A tongue of cool weather has persisted down the center of the country for months, while the farther west you go, the hotter it gets, culminating with the record heat in California.
September fit that trend, with the average temperature well above, but not near record levels in the Lower 48 states. According to the National Climatic Data Center’s latest monthly update, the average temperature was 1.3 degrees Fahrenheit above the 20th century average, ranking it as the 26th warmest September. Precipitation for the month across the country was 0.09 inch above average, ranking near the middle. Continue reading

Big surge of subtropical moisture possible early next week
Moisture will be plentiful across Colorado and much of the U.S. the next 5 days.
FRISCO — Hurricane Norbert, now spinning off the coast of Baja, California, could deliver copious amounts of moisture to Colorado early next, according to the National Weather Service, which is already talking about the potential for regional flash flooding.
The Category 3 storm is expected to weaken gradually during the next few days as it moves northwest over cooler water, but the projected path turns the remnant low pressure system eastward, coming ashore over northern Mexico or southern California late in the weekend.
The exact path will determine how much rain falls in Colorado, but National Weather Service forecast maps are showing widespread rain across Colorado, with a bullseye over the north-central mountains.
Grand Junction-based National Weather Service forecasters say subtropical moisture will increase across the Great Basin and western Colorado Monday as a low pressure area off the SoCal coast directs Nortbert’s remnants and more monsoon moisture northeastward.
Storms will be widespread by Monday afternoon with the potential for heavy rain and small hail, as well as a chance for flash floods and debris flows.
Dry air (brown) prevailed over Colorado Saturday morning, but Hurricane Norbert may help boost another surge of late-season monsoon moisture poised to the south.
