Updated September 18, 2017 UNSETTLED ACROSS THE WEST --> This week we expect a few Gulf of Alaska storms to move through the western US, and drops snow to some mountain areas across Washington, Oregon (Cascades), Idaho, Montana, Wyoming (northern Rocky Mountains), California, Nevada (Tahoe), and Utah (Wasatch). By Saturday we may see some snow for Colorado also, as the trough weakens, warms up some, and shifts east. Luckily, the mountains and resorts in Colorado are so elevated, that despite the warming, snow is still possible. More details are coming. The East Coast (+ the resorts) will be sitting under a high pressure ridge, with warmer than average weather. CMBY and AFTER THIS WEEKEND... High pressure ridging will start to dominate the western US, for quite a late summer season warm-up. This should affect all areas, though Colorado will be dealing with some unsettled weather to start (Sat and Sun). This ridge over the west should last through 7 to 10 days, turning unsettled again (storms) after the first few days of October, but more so by the 10th or so as low pressure deepens across the west (colder, snow more likely for many areas).

-Winds are increasing, and milder air is moving in before the cooler high temperatures we expect today, as low pressure over Nevada and Utah is moving in closer. The strong and cold (but weakening) low pressure system mentioned approaches the area, and we expect cooler weather and showers as this low pressure moves in toward Colorado. We expect some snow to mid and upper mountain Aspen-Snowmass resort elevations, and base to top at Summit County/ Grand County resort areas by Saturday night and Sunday. Southwest Colorado including Telluride Resort will see some light snow mainly above 10,000 to 11,000 feet. Low pressure lingers across the area into early next week, with showers and higher elevation snow expected to decrease to mostly isolated on Monday, then dry after as high pressure ridging tries to build in. CM
LONGER RANGE... High pressure sets in mid and late next week (last week of September), and into early October as strong high pressure ridging builds over the Pacific Northwest and Northwest US, for mostly sunny skies and milder temperatures for Colorado and the west. The next chance for snow and cold is looking to set in after the 5th of October, and before the 10th. CM
