Detailed Summary:

Scattered precipitation along with temperatures closer to seasonal average is in store for most of 
the country thanks to a shift in the weather pattern. The much warmer temperatures that has been 
anchored over the Southeast will move westward over the Gulf states while allowing a slight cool 
down from the Carolinas to Florida. Very warm/hot conditions will continue across the South but at 
levels below hazardous thresholds. Rainfall will become less focused and driven by weaker dynamics 
(more typical of summer). 

An elevated threat for heavy rainfall Monday and beyond will span from Oklahoma to Illinois.
Soil moisture remains well above normal and close to record levels across most of the central U.S. 
Expect some heavy rain to occur in this target area near a frontal boundary but this will be 
refined over the next few days. River flooding is expected to continue through the period as the 
tributaries continue to carry water into and through the main stems.

No hazards were depicted for Alaska as a system moves through the southern Gulf of Alaska next 
week, keeping most of the rainfall over the ocean but perhaps into the Panhandle.
