conditions. A few showers or storms will be possible but will be 
very isolated in nature. Breezy conditions are expected midweek 
onwards for each afternoon but RH will remain high enough that 
critical fire weather conditions will not be a concern. Isolated 
precipitation may return for the weekend and beyond.
