.DISCUSSION...
Seasonably hot temperatures and dry weather are expected to
continue through the weekend and into next week. Winds will be
light and mainly terrain driven, with weak north winds developing
Saturday morning. Humidities trend lower as ridging sets up aloft,
resulting in poor overnight recoveries and elevated overnight
temperatures in the foothills. Well above normal temperatures and
dry conditions are currently on track to persist through much of
next week as well.
