.DISCUSSION...Another warm and mostly dry day is anticipated.
Increasing mid-level moisture will lead to an increasing chance of
showers and thunderstorms mid afternoon through evening hours
(mainly 3pm-8pm) today and again on Sunday with a chance of
showers overnight. There is a chance of wetting rain but it will 
take a direct hit from the core of a thunderstorm. Watch for gusty
outflow of 30-40 mph near any thunderstorms, otherwise winds will
be light and terrain driven. 

A night-time inversion is expected tonight with only modest Rh 
recovery on the slopes with a gradual diminishing influence of 
night time inversions/thermal belts in the following nights, thus 
improved Rh recovery at night. 

The pattern change to cooler and wetter begins Tuesday and lasts
through the coming week. Temperatures return to seasonable levels
(highs in the upper 60s to lower 70s with daily min Rh of 45-55
percent. Daily wetting rain chances will be 40-60%. There is about
a 60% probability of at least 0.50" of moisture next week.
