.DISCUSSION...Hot, dry, and unstable conditions continue for the
region. Main concern over the next 36 hours will be the arrival of
a weather system that could produce dry thunderstorms for the
area, primarily during the morning to early afternoon hours on
Wednesday. Confidence is on the lower end as to the exact
coverage of thunderstorms, but current thinking is that the
greatest threat for storms lies west of the site. Otherwise,
expect light, terrain-driven winds.
