.DISCUSSION... Moisture is gradually moving back into our area. 
Today this moisture is resulting in isolated dry thunderstorms. 
As a result, the main concerns are strong wind gusts around storms
and lightning. As atmospheric moisture increases over the coming 
days, shower and thunderstorm coverage should increase, and 
precipitation will have a greater chance of making it to the 
ground. Although moisture and minimum relative humidity are  
expected to increase, this change will be gradual and localized 
Red Flag conditions are possible where it is dry due to gusts 
above critical fire weather thresholds in local areas.
