Colorado: Finally, some snow in the forecast

Weather change coming, details uncertain

A Gulf of Alaska low will start to move toward western Colorado later this week.

By Summit Voice

SUMMIT COUNTY — All those snow dances and sacrificial bonfires could pay off late this week as the weather pattern across North America looks to flip-flop, with high pressure in the West giving way to a broad Pacific trough that promises to bring widespread precipitation to the region.

But it’s too early to tell exactly where the snow will fall. For now, the forecast models are predicting that a vigorous cold front will cross Colorado Friday night into Saturday, bringing the best chance for snow. Continue reading

SUMMIT COUNTY — A classic spring storm is rolling across the West, marked by a deep trough of low pressure extending down into the desert Southwest. As an “inside slider,” the low will move east of the Continental Divide and set up a deep, moist northeast flow that could produce significant snowfall on the east slope of the Front Range under upslope conditions.

A winter weather advisory from 12 p.m. Tuesday night to 6 p.m. Wednesday (May 11), with 4 to 8 inches of snow possible above 7,000 feet along the Front Range. The winter weather advisory extends to the higher terrain of Summit County, where the National Weather forecast also calls for the chance of 4 to 8 inches of snow across the higher terrain. A-Basin could pick up some decent snow once the weather system moves east of the area Wednesday and the flow switches around to the north.

Farther west and south, around Vail, Aspen and Crested Butte, a winter storm warning is in effect, with heavier snow expected across south-facing slopes Tuesday night, shifting to north-facing slopes Wednesday. Continue reading

SUMMIT COUNTY — A typical winter weather pattern is developing over Summit County, as a moist northwest flow rushes down from the Gulf of Alaska and over the state. Short periods of high pressure will bring dry and clear interludes, alternating with embedded disturbances bringing showery periods through the first half of next week. None of the systems looks to produce big dumps, but our snowpack will build, inch by inch.

Storm totals for the last two days include 10 inches at Wolf Creek, 6 inches at Copper Mountain and four inches at Loveland. Friday looks dry and cool, with highs in the mid-20s and a strong inversion that will trap cold air and smoke in the valley floors, possibly all day long. Lows the next few night are forecast to drop into the low single digits. The average high for Nov. 12 is 40 degrees, the average low is 12 degrees. The record high, 62 degrees, was set in 1952 and the record low, minus 18 degrees, was set in 1911. Continue reading

Most of next week is forecast to be cold, with snow on and off

By Summit Voice

SUMMIT COUNTY — If you like it nice and warm, enjoy the weekend, and if you’re looking forward to more snow, you shouldn’t have to wait too long.

The National Weather Service is forecasting a major change in the pattern beginning Sunday, as a weak disturbance will graze the area with showers and bring gusty winds. Subsequently, a series of wintry storms will move across Colorado. The first is forecast to bring strong winds and significant snow Monday night into Tuesday, along with below-normal temperatures. Another storm is on the horizon for Thursday, and the final in the series could roll through next weekend. Continue reading
