.DISCUSSION...Warmer and drier conditions will build through this weekend
with interior valleys warming back into the mid 80s with RH below
30 percent. Strengthening thermal belts will promote poor overnight
RH recovery at high elevations. Winds will be generally gentle
except for some gusty north wind near the coast and gusty northeast
wind up to 25 mph along high terrain Sunday into Monday. Warm and
dry weather will persist through at least mid next week. Late this coming
work week, rain showers are possible, especially for the North Coast.
