KEY MESSAGES

- Increasing confidence in much colder temperatures for the latter part of the week. Some higher elevation snow is looking more likely as well.
DISCUSSION
Issued at 1216 AM EST Sun Nov 8 2026
Pleasant fall weather can be expected over the next few days as a large area of surface high pressure remains over the region. Expect chilly nights and mild days with high temperatures in the 60s for most valley locations each day through Wednesday.
A change will be arriving for the latter part of the week as models continue to show a shift to more winter-like conditions. While there are disagreements in the details, models generally show an upper low digging south out of Canada Thursday and Friday as multiple short waves rotate around the upper low carving out a deep eastern CONUS trough.
An initial short wave and associated cold front will likely bring some rain to the area Wednesday night into Thursday. Colder air will move in behind the front, and the colder air will then be reinforced as subsequent short waves rotate around the upper low. The details are still uncertain this far out and will be important, but this set up looks favorable for some wintry precipitation especially across the higher elevations, with accumulating mountain snowfall possible that will likely be enhanced by upslope flow. High temperatures may struggle to make it much above the 40s in many valley locations both Friday and Saturday.
