.Monsoon moisture combined with upslope flow behind a cold front 
will lead to an enhanced risk for locally heavy rainfall with any 
stronger thunderstorms that develop across the southeast mountains 
this afternoon and evening.  This may cause flash flooding on burn 
scars, as well as areas which have saturated soil conditions from 
recent heavy rainfall.
