Arapahoe Basin Discussion
Today and Wednesday we expect a couple of weakened Pacific storms to move through, 1 each day, with mainly just some clouds for Aspen, but snow, light, for areas along the divide Tuesday night through Wednesday night. 4 to 7 inches of snow are possible for places like Winter Park Tuesday night through Wednesday night (Thursday looking nice). Aspen remains snow-free for now, except for some light snow on Wednesday.

Thursday and Friday of the coming week we expect a high pressure ridge and mostly sunny/ milder weather all across western Colorado. Low pressure and some snow is expected to follow this... in the days leading up to Christmas, mostly light to moderate accumulations, then heavier snow is possible Christmas Eve and Christmas Day with a stronger looking storm. We are then looking busy between then and the New Year Holiday, with some significant looking storms. Between then and the 10th and 15th of January, we may see a bit of a snow drought while the east coast gets hammered with snow for 2 weeks... THEN, snow returns on a regular basis for Aspen mid-January onward for a week+. CM
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 chris@snowforecast.com 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!

LONGER RANGE:
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! We do not charge for any of our info, and have been providing it all for free since 1998, "Predicting Sick Days since 1998"! CM
