.DISCUSSION...Warm and dry conditions will prevail through the 

next few days with cloudy conditions developing each night and 

continuing into the morning. The neighborhood will see 

southwesterly winds with wind speeds varying greatly due to the 

local terrain. Wind gusts of 15 to 20 mph are possible each 

afternoon and evening at and upstream of the ridgeline along 

Wildcat Canyon Road. At the project site, winds will top out at 

around 10 mph with light and terrain-driven winds dominating each 

night and morning. Contrasting impacts from the northeast aspect

and the locally downsloping windflow make the humidity and

temperature forecasts difficult. Expect a warming and drying trend

to continue through the early part of next week.
