Confidence in the Extended Outlook:

Confidence is average overall. Forecast confidence is higher early in the outlook, with good agreement on the large-scale weather pattern. Confidence remains average later in the period, although the western U.S. pattern becomes more complex and forecast models diverge on the evolution of troughs and ridges, leading to greater uncertainty in the exact placement and timing of hazards.
