December 07, 2018 - Aspen and Western Colorado Short/ Long Range Outlook
Mostly light additional snow, then a mostly sunny weekend, and more snow next Tuesday and Wednesday (heavier)!
HOW ARE WE DOING (please contact firstname.lastname@example.org or comment below)? Let us know please...
Light snow for most areas including Aspen, and across southwest Colorado...
-The latest storm absolutely dumped RAIN and snow across southern California, is headed mainly along the Mexico border now, and taking a southern track... El Nino style, with a few" of snow across southwest Colorado to Aspen's mountains, under a moist southwest flow of moisture across the mountains, while most energy passes to the south
This coming weekend
we expect a high pressure ridge to build in, with cooler air dragged into Colorado initially on Saturday, as the southern tracking low pressure system exits (northwest/ north flow of winds from the colder north), and sunshine pops through in the then drier air... Powder + sunshine, what Colorado is known for!
It looks like El Nino is not an official anomaly yet, as I expected in my September LR forecast (for Aspen and SW Colorado
/ For northern Colorado resorts
) so we are in an ENSO Neutral phase, though in the latest update from NOAA, we are seeing warming waters, still a weak El Nino at best. This may explain the more southerly tracking storm systems we have seen, and will likely see in the coming weeks of December and January. CM
Next week, the 11th onward, we expect a couple of snow storms and some moderate to significant snow for western Colorado. Because these look like strong and cold systems (ask Niseko, Japan
) with a good fetch of moisture across the Pacific, they are capable of good snowfall across all of western Colorado if the track is right (a bit more north). It looks like 2 storms total for next week, one Tuesday/ Wednesday and another late next week. CM
(NO CHANGE from the last LR update) : It is looking like we may see a busy time as we approach the Christmas and New Year holiday period, with some significant storms possibly lining up to affect all of the western US including Colorado... We expect to see a 7-14 day period of down time and mostly sunny skies following this series of storms, that may start around/ after Christmas. In January we see that down time to start the month (a week-ish), then storms should kick in again on a more regular basis, but possibly favoring northern resorts this time as the east coast gets hit hard and these systems brush mainly northern Colorado. More updates are coming. Do you have any ideas on what you want to see in our discussions? Please contact through the site!
