Critical fire weather conditions continue today as winds are 
expected to gust up to 35-45 mph in the afternoon and relative 
humidity again drops into the single digits. Thursday and Friday, 
dry air remains but winds weaken, leading to more spotty areas of 
critical fire weather. A brief system passes through Saturday, 
once again ramping up gusts without any moisture relief, 
increasing fire weather concerns once more.
