Updated Wednesday September 18, 2019 at 4:45pm MST

Yesterday "Moisture decreases and we expect isolated showers and a thunderstorm possible while low pressure moves in mainly up north... Any thunderstorms and showers end this evening as upper level instability departs with the low pressure system"

Today through Friday - Temperatures become warmer, with conditions becoming windy today and Thursday in advance of a weakening low pressure system moving across the northwest US, then hitting western Colorado and Aspen with some upper mountain snowfall (light) Thursday night and into Friday morning, down to about 10,500 feet. A cold front is expected to move through Thursday night as this system clips Aspen, and carries in limited moisture, with light snowfall then. On Friday we see clearing and drying as low pressure is deflected toward the northeast. Friday looks cooler post cold front.

Saturday and Sunday - A beautiful and warmer, drier, sunny weekend in Aspen is coming up, though winds do increase mainly Sunday with the approach of the next low pressure system...

Monday and Tuesday - Cooler with a low confidence (in placement of/ location of the low) storm system moving through next Monday and Tuesday with some mid and upper mountain snowfall for Aspen-Snowmass....

LONG RANGE OUTLOOK: Low pressure may move out next Wednesday, but the next low pressure system will be close on its heels, and moving in later next week and weekend (27th-29th or so), a break, then a stronger system moves in to kick off October, this time with the lower snow levels, to 9,000 feet or lower in Aspen and across western Colorado.

From the last update: I think that Gulf of Alaska low pressure is going to start becoming more persistent as we move through October, which should mean showers from the Gulf of Alaska low pressure systems, and some lower snow levels to 9,000 feet or lower to kick off early October. Check "weather stories" from the home page, for a 2019-2020 season outlook for Aspen, and a recap of the awesome 2018-2019 season!

ENSO Neutral is the pattern expected for fall and winter 19-20'. This does not produce much in terms of definitive weather. No matter, there are other factors. A fall/ winter 2019-2020 weather outlook for Aspen is linked off the home page, but a quick glimpse: Colder and more snow than usual this season, with another early start.
