The perfect weather index is definitely off it’s peak which was an 8.0 mean for the nation in mid-September (Thursday 6.8). With cold air beginning to intrude from the north I think there is little doubt we won’t see 8.0 again until May or June. But that doesn’t mean perfect weather won’t exist, it won’t just be found in different places. Thursday will be the first day in quite a while when Tennessee tops the list. Not many perfect 10’s in the Volunteer State except right along the border of North Carolina. A few more perfect 10’s in far eastern Kentucky tomorrow including: Flint, Diane, and Pansy. A few in Virginia as well around Woodlawn and Floyd.
Out West, a pocket of 10’s in central Utah including Delta and Fruita. A few more showing up in Coastal California including: Shively, Myers Flat, Comptche, Anderson, Palo Alto, and Greenfield. A few in Southwest Oregon as well including: Drain, Coquille, Sutherlin and Oakland.
The storm in the Northern Rockies and Upper Midwest will usher in some really cold air into the West. Many locations will see there first hard freeze tonight. Some of the most vulnerable areas are: the Willamette Valley in Oregon, the Treasure Valley in Idaho, all of Montana, Wyoming, and North Dakota will see either a freeze or hard freeze. Much of Colorado except the far west and far east will see frost or freeze. In Utah from the Wasatch east will see freezing conditions as well.
