Moisture above average for the year to date

FRISCO — An extended monsoon season lifted August precipitation in Breckenridge to well above average, as weather-watcher Rick Bly tallied 4.22 inches of water for the month. The average rainfall for August is 2.26 inches; August 2013 was the wettest August since 1984.

“We had a good month for precipitation,” Bly said, adding that the rainfall often came at night, when it’s even more beneficial because it has a chance to sink into the ground before evaporating.

All in all, the 2012 water year has been up and down, with a “desperately dry October and November, according to Bly, followed by a so-so early winter and a gangbusters spring, with drought-busting snows in April and May. Continue reading

The remnants of Tropical Storm Ivo, off the coast of Baja, are pumping tropical moisture into the Southwest.

Tropical storm off Baja pumping moisture into Southwest

FRISCO — So far, the Atlantic hurricane season hasn’t been particularly active, but in the eastern Pacific, nine named storms have formed, most of them moving out to sea with little impact to land areas.

But the latest in the series, Tropical Depression Ivo, is dawdling off the west coast of Baja California and sending moisture streaming into northwestern Mexico and the southwestern U.S. The moisture could affect much of western Colorado and eastern Utah Sunday and Monday, with another round of heavy thunderstorms possible.

Monsoon rains brought above-average moisture to Summit County in July.

By Bob Berwyn

FRISCO — July brought above-average moisture to both official National Weather Service sites in Summit County, especially in Dillon, where the monsoon delivered 3.35 inches of water, about 1.47 inches more than average for the month.

At least a trace of precipitation was reported on all but seven days at the Dillon weather observation station, with the wettest days on July 25 and July 26, both delivering about a half inch of moisture.

The average daily maximum temperature at Dillon during July was 74.4 degrees, just .10 above average, but the daily average low temperature was 39.8 degrees, nearly 4 degrees above average, probably due in part to plentiful nighttime cloud cover. Continue reading

FRISCO — Flashes of lightning, loud thunder and heavy rains Friday marked the start of Colorado’s summer monsoon season. The one- to 2-month period when moist and warm air flows northward from the subtropics may not be as dramatic as the Asian monsoon, but it’s still a critical piece of the state’s overall weather picture, providing abundant moisture just at the time when forests and fields are reaching their driest point.

FRISCO — June, the second-driest month in Summit County, ended up especially dry this year, with only 0.26 inches of precipitation at the official National Weather Service site in Breckenridge, and even less — 0.19 inches at the Dillon station.

Averages for the two sites are 1.37 inches in Breckenridge and 1.14 inches at Dillon, where there was measurable precipitation on two days, June 18 and June 29.

The sparse total in Breckenridge made it the fourth-driest (tied with 2006) on record, dating back more than 100 years, said weather observer Rick Bly. The driest June ever (0.06 inches) was in 1980, during another notable Colorado dry spell, followed by June 1891 (0.10 inches) and June 2002 (0.24 inches). Continue reading

Paintbrush starting to bloom in the sage scrub!

FRISCO —Even the drive-by spots in Summit County are just littered with wildflowers these days, and some of the best spots to look are in some of the areas that were clear-cut a few years ago. Bright sunlight and plenty of moisture this spring have spurred an amazing variety of flowering plants where there was once only pine tree litter. Meanwhile, the sky was putting on its own show, preparing to fire up a nice round of thunderstorms. Continue reading
