1231 AM PDT Sun Oct 5 2025
.DISCUSSION...Warmer and drier conditions will continue to build into
the first half of the work week 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.
