.DISCUSSION...
Persistent summer conditions are expected to continue. Localized
critical fire weather conditions will develop with afternoon winds
early this week, but winds remain below thresholds on a regional
scale through the week. A stream of moisture will continue to work
northward providing fuel for terrain based showers and
thunderstorms each afternoon. Wetting rains are possible, as are
gusty winds and some small hail. Temperatures increase by late
week.
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
