Short range forecast-->
- We will soon be writing a short range weather forecast discussion here, covering the western US and southwest Canada. If you have any input/ requests/ critiques, please email them to me We have had 17 years so far online, forecasting detailed weather for resorts all across the western US, and gaining the trust of many.
7 day to 2 week+ forecast (since 1998) - Next Monday and through all of next week/ weekend, we expect mostly warmer than average temperatures and mostly sunny/ dry weather across most of the northwest US (including WA, OR, ID, WY), with low (Wyoming) to no threat of thunderstorm activity. Sunday and early next week, the southwest US including California will see showers and some mountain snow as a cold core closed low pressure system moves through California, then across the deserts. Utah will see some higher mountain snow as well, and between Utah, even southern Nevada (Mt Charleston), northern Arizona, and southern California, we expect some snow above 9,000 to 10,000 feet, so the mountain peaks will likely see their first snow of the season. The western US as a whole looks drier and warmer than usual possibly through mid-October under unusually strong high pressure ridging aloft (there is more detail at the bottom of the page).
7 day to 2 week+ forecast (since 1998) - Next weekend we expect warmer than average temperatures and mostly sunny/ dry weather across the western US, with low to no threat of thunderstorm activity. Next Sunday and Monday (11th/ 12th) the Pacific Northwest (including northern Idaho) is hit with rain and high mountain snow as Gulf of Alaska low pressure moves in, while the rest of the west is dry and warmer than average. Early the following week, Mon/ Tue the 12/ 13th, we may see some upper mountain snow for Montana and Wyoming as the previously mentioned low pressure system moves through. Otherwise, the western US as a whole looks drier and warmer than usual through mid-October under unusually strong high pressure ridging aloft. Toward/ after October 20th, we may see stronger low pressure move into the northwest US out of the Gulf of Alaska.
The El Nino SST pattern is strong, right now, and it looks like we will see a VERY strong El Nino this fall and winter, possibly stronger than the 1997-1998 version, which is the strongest (in terms of SST anomaly) on record. This set-up would usually cause heavier rain and snow across California (mainly southern and central, possibly including Tahoe, but especially including Mountain High and Big Bear, as the epic 1997-1998 season can attest to) and the southwest US this winter. This would be a vast improvement for Tahoe-Mammoth. Southwest Colorado and northern New Mexico usually do well, including Taos Ski Valley, who had a great season in 2014-2015 with the weak El Nino(ish) anomaly. Aspen is in between, and we would say average snowfall should be expected at Aspen-Snowmass in 2015-2016. We will be posting a detailed outlook for Aspen-Snowmass, Squaw Valley/ Tahoe, Mountain High, and Taos Ski Valley in the coming months. We will be monitoring the progress of this right here, stay tuned... CM
In the Northern Idaho Panhandle between Montana and eastern Washington, approximately 50 miles south of Canada and 11 miles northwest of Sandpoint, Idaho, you will find Schweitzer Mountain Resort. With the addition of Stella, Idaho's first six-pack, Schweitzer now boasts 2,500 acres of varied and exciting terrain. The area consists of two very large bowls, and within each of the two, there are two smaller bowls divided by gradually sloping ridges.
