.DISCUSSION...Elevated relative humidities will keep critical 
fire weather conditions suppressed through Saturday. Warmer and 
drier conditions return Sunday as we begin another hot and dry 
period. However, afternoon winds are expected to remain below 
thresholds beneath high pressure next week. Thunderstorms will 
become less widespread by Sunday, but remain a concern over the
higher terrain for the week ahead.
