.DISCUSSION...

A moist airmass accompanied by daily chances for 
showers and thunderstorms through early next 
week will keep any fire weather concerns to a minimum. 
Upper level ridging is expected to nudge east by the weekend
which may reduce shower and thunderstorm coverage; however,
isolated to scattered chances are still forecast across 
mountain locations, with the aforementioned moist airmass
remaining in place areawide.
