Record-Setting Heat Ends for Most in the Central U.S.
The ridge of high pressure that has been dominating parts of the west and central United States will start to break down into the start of the weekend, which will allow for cooler air from the north to start filling in. This will end *most* of the record warmth for the 4-Corners and surrounding areas.
On Saturday, potential record warmth will spread eastward into the Southeast and Southwest. We are not expecting as many records as Wednesday and Thursday because the jet stream will begin to push southward some.
Potential record highs will be from Wyoming to Nevada and New Mexico. Then the potential record highs will move even farther southwest into the desert valleys of Arizona, California, and Nevada through early next week.
A strong cold front will continue to bring in colder air this weekend, especially Sunday to Tuesday along the Pacific Northwest and Rocky Mountain region. However some heat will still remain across the desert valleys of the extreme southwest U.S. into the early part of this week.
Looking longer-term, it appears the immediate West coast will begin to trend cooler by the second week of December. Until then, it may not feel quite like holiday weather in your neighborhood!
