.DISCUSSION...

Critical fire weather conditions are not expected to develop this
week, as relative humidities remain elevated thanks to ample 
moisture across the region. Wetting rains remain in the forecast, 
with some flash flooding risk each day on flood prone burn 
scars and within flashy drainages. Lightning from thunderstorms 
will remain a threat to crews as well.
