Summary of Forecasts and Hazards

US Hazards Outlook
NWS Climate Prediction Center College Park MD
300 PM EDT July 26 2024

Synopsis: A strengthening and westward shifting area of mid-level high pressure supports an elevated risk of excessive heat conditions along with increased chances for high winds for the western half of the contiguous U.S. (CONUS). A secondary area of strong mid-level high pressure centered over the New England is expected to maintain elevated chances for excessive heat for much of the Mid-Atlantic, eastern Great Lakes and the Northeast through the middle of week-2. A healthier monsoon circulation, as well as possible tropical cyclone activity in the eastern Pacific leads to increased chances for heavy precipitation over parts of the Desert Southwest. Possible tropical cyclone development in the Caribbean leads to increased risk for heavy precipitation and high winds to portions of the eastern Gulf States.
