...FIRE STARTS DUE TO ABUNDANT LIGHTNING POSSIBLE SUNDAY NIGHT 
THROUGH TUESDAY MORNING...

.A moist and unstable midlevel airmass is forecast to spread
north across the region Sunday. As that takes place, isolated 
thunderstorms may develop over Mendocino and Lake counties during
the day Sunday. Additional thunderstorm development will be more 
likely Sunday night into Monday morning across much of Northwest 
California as the remnants of a tropical system move north across
the area. Another round of storms will be possible during Tuesday
morning as a second upper disturbance ejects eastward across the 
region. Lightning combined with dry fuels will increase the threat
for fire starts during each episode of storm development.
