US Hazards Outlook NWS Climate Prediction Center College Park MD 300 PM
EDT July 11 2025
Synopsis: Mid-level high pressure is forecast
across much of the contiguous U.S. (CONUS) during the week-2 period. However,
anomalies are forecast to be relatively weak early in the period, even for the
summer months when mid-level anomalies are generally reduced. Mid-level high
pressure begins to increase across the western Gulf Coast and Lower Mississippi
Valley by the middle of the period, increasing chances for extreme heat in
these regions. Late in the period, mid-level high pressure expands across the
West, bringing increased chances for extreme heat to portions of the Northwest.
Chances for heavy precipitation are increased across the southern Atlantic
States and Central and Eastern Gulf Coast due to a stalled frontal boundary. In
the Midwest, a warm front moving through the region may increase chances for a
period of heavy precipitation.

heavy precipitation for portions of the Gulf Coast, Southeast, and
