Long duration #heatwave expected Friday through early next week in California. Minimum temperatures in the low/mid 70s will provide little to no overnight relief to those without adequate cooling or hydration. Heat Advisories and Extreme Heat warnings for parts of central and southern California.

Warning of a prolonged late‑season California heat wave: text and color maps show major-to-extreme heat risk concentrated in Southern California and the Central Valley with peak temperatures in the 100s and safety guidance to stay hydrated and use cooling.

Storms producing heavy rain will continue to push east across portions of the Southern Plains today. Numerous flash flooding events are possible. Visit weather.gov for your local forecast updates! For flood safety information, visit weather.gov/safety/flood....

The map shows a broad band of heavy rainfall indicating 1.5 to over 5 inches of precipitation stretching from Texas and the western Gulf Coast northeastward through the Mississippi Valley and into the Great Lakes.
