.DISCUSSION...

Temperatures gradually trend warmer through the week under clear 
skies as high pressure builds. Strong inversions will develop 
quickly around sunset each night along with excellent humidity
recovery at night, with the inversion trapping smoke in drainages. 
Inversions will lift in the late morning near 1000 Thursday and
Friday. Winds will generally be light with speeds less than 5 mph. 
 
If conditions become unrepresentative, contact the National Weather
Service.
