DISCUSSION

UNSEASONABLY WARM AND DRY THROUGH FRIDAY:

High pressure will persist through the work week bringing unseasonably warm and dry conditions. Temperatures are expected to run 5-10 degrees above normal through Friday.

COOLER, WETTER THIS WEEKEND:

By Friday afternoon, high pressure will have moved east of the Divide, and flow aloft will shift southwesterly. This will begin to advect in rich subtropical moisture. A quick moving wave will track inland through the Great Basin Friday night into Saturday, acting on this rich moisture. Valley rain, mountain snow above 8k-9k feet, and an isolated thunderstorm or two are expected through the day Saturday. The highest probability of accumulating snow remains over the San Juans, generally above 10k feet. The likelihood of 6+ inches of snow for the San Juans remains high (70-80%), while the likelihood of 12 or more inches remains low (<20%). While the Central Colorado mountains are the next most likely areas to see accumulating snow of 6+ inches, the NBM probabilities keep that likelihood on the lower end (<30%). As high res guidance comes in over the next 24 hours, we'll get a better handle of snow totals and timing or greatest impacts. Slippery to hazardous travel will be possible over the mountains passes Saturday into Sunday. Snow levels are expected to drop to 6k-7k feet by Sunday morning, however the bulk of the precipitation will be over by then, with only lingering orographic showers expected. Temperatures through the weekend will run near-normal for mid- November.

UNSETTLED INTO NEXT WEEK:

The wavy, unsettled pattern continues into next week. Models are indicating the potential for another round of mountain snow and valley rain in the Tuesday to Wednesday timeframe. Confidence on the details of this potential system remains low, however, as a wide variety of solutions exist regarding the track, timing, and strength of this system.
