As the current unprecedented heat dome starts to diminish, NOAA's Climate Prediction Center has issued a warning regarding a second, potentially more intense heat wave developing for mid-July. This wave is expected to impact 22 states, including areas in the Southwest, Central Valley of California, the Plains, Mississippi Valley, and the South Atlantic region. Weather models indicate an unusual mid-level ridge forming over the Four Corners region by July 14, which could elevate temperatures to extreme and record-breaking levels. Researchers caution that this heat could linger for three to five days without any respite, leaving millions who are already affected by this week's high temperatures with very little time to recover.
