FRISCO — Despite early projections for above-average hurricane activity in the Atlantic, the season ended Nov. 30 with a whimper after the fewest number of hurricanes since 1982. Even so, the storms that did form killed more than 140 people and resulted in $15. billion in damage.
In a release, NOAA attributed the low activity to persistent, unfavorable atmospheric conditions over the Gulf of Mexico, Caribbean Sea, and tropical Atlantic Ocean — especially early in the season, when dry and dusty air dominated the atmosphere off the coast of Africa and into the central tropical Atlantic.

FRISCO — Drought conditions may persist across the southwestern U.S. this winter and may redevelop across the Southeast, according to the seasonal outlook from NOAA’s Climate Prediction Center.
“Even though we don’t have La Niña, the atmosphere across the Pacific seems to be stuck in a La Niña mode … It’s been quite surprising to us, how persistent the pattern is,” said Mike Halpert, acting director of the Climate Prediction Center.
SUMMIT COUNTY — Federal weather experts said they are expected an above-average to active Atlantic Hurricane season this summer, urging residents of coastal and near-coastal areas in the southeastern U.S. to start preparing now.
Based on a combination of climate factors, NOAA predicted as many as 13 to 20 named storms, with seven to 11 of them developing into full-fledged hurricanes and potentially three to six major hurricanes with winds of more than 100 mph.
Factors involved in the forecast include a continuation of overall climate conditions that have resulted in an active pattern since the mid-1990s: Above average sea surface temperatures in the tropical Atlantic and ENSO-neutral conditions in the Pacific which leads to less windshear, lower air pressure and overall atmospheric circulation that’s more conducive to hurricane formation.

Drought expected to persist; water supply outlook grim

FRISCO — Temperatures will begin to moderate across the Colorado high country the next few days, with highs climbing back to near seasonal norms, which is only in the lower 30s, but that should feel downright balmy after enduring an Arctic air mass the past few days.
The nicest weather will be up on the mountain slopes, because warmer air aloft will trap cold air on the valley floors, and with no incoming weather systems to stir up the atmosphere, those inversions are likely to persist for the foreseeable future. That also means there’s no snow in the forecast for the next 10 days unless there’s a dramatic shift in the jet stream, which will stay far to the north for the next week at least.

If you’re holding out for more snow before heading out to make turns on the hill, you may want to reconsider. The outlook for the next 10 days is mostly dry and warm, with perhaps a chance of snow brushing the northern mountains Sunday night into Monday morning. Beyond that, another ridge will build into the Southwest, bringing more dry weather and a return to above normal temps for much of next week. Continue reading “Colorado: Mostly dry into December”→
FRISCO — It’s still early in the season, but so far, this year’s snow pack in Colorado is running behind even last year’s meager totals for this time of year, as the little bit of snow that fell last month melted away some of the SNOTEL sites.
The Copper Mountain SNOTEL site was reporting 4 inches of snow a few weeks ago, but is now back to zero, for example, and numerous other SNOTEL sites are also reporting at zero.
NOAA calls for warmer-than-average conditions in the West

SUMMIT COUNTY —This year’s wavering El Niño isn’t just vexing Colorado forecasters. Forecasters with the National Oceanic and Atmospheric Administration say that getting a handle on the winter forecast has been tough.
“This is one of the most challenging outlooks we’ve produced in recent years because El Niño decided not to show up as expected,” said Mike Halpert, deputy director of NOAA’s Climate Prediction Center. “In fact, it stalled out last month, leaving neutral conditions in place in the tropical Pacific.” Continue reading “‘Wavering’ El Niño vexes winter weather outlook”→
