.DISCUSSION...

Isolated showers and thunderstorms continue on the mountains, 
with better chances for thunderstorms Thursday and Friday. Wetting
rains and snow increase in likelihood on Thursday and Friday too.
Gusty outflows will continue to threaten around showers. Warmer, 
drier conditions return this weekend for the lower elevations, 
however critical fire weather conditions are not expected due to 
lighter winds and higher relative humidities.
