.DISCUSSION...An influx of monsoonal moisture will raise RH to
above critical levels for the next several days for much of the
area. Great Basin zones will experience lower RH today and
tomorrow. Widespread showers and thunderstorms will also be
around. With this shower activity come higher chances of wetting
rains. Ambient wind will remain below about 15-20 mph in most
areas, but thunderstorms will bring periods of higher wind gusts
to 40 mph.
Note: Thunderstorms imply gusty and erratic winds.
