High pressure over the western half of the continent will keep us sunny and dry for the first few days this week. This high-pressure ridge will begin to break down midweek, and big changes will arrive by Black Friday. On Thanksgiving itself, there is a chance of high-elevation snow or slush, so holiday travel will be hazardous over mountain passes. The snow will become more widespread on Friday thru Sunday.
Have a great week!
