.DISCUSSION...
Warm and dry conditions continue to persist this week. There
will be improvement in minimum humidity (MinRH) across the
Sierra Nevada and Mojave Desert on Monday but a 10-20% chance
of thunderstorms in the Sierra Nevada. Temperatures also lower
on Monday before another warmup brings temperatures to several
degrees above average on Wednesday until Friday. MinRHs lower
slightly due to the warmup, but not as drastically as the past
few days. Winds generally will be light and terrain-driven.
