Confidence in the Extended Outlook:

Confidence is good in the earlier period for multiple days of hazardous heat because of good agreement on the large-scale pattern. Confidence is average later in the outlook, with reasonable agreement on broad ridging but uncertainty about its strength, changes in the Northeast pattern, and precipitation across the central United States.
