.DISCUSSION...Interior conditions will quickly dry back out today
aided by gentle northeast wind. Interior highs will return to the
80s with minimum RH as low as 20 percent. That said, marine
influence will linger along shore and in near coastal valleys,
particularly in Humboldt County. Conditions will gradually warm
and dry into early next week when highs will peak back in the 90s
and with marine influence shallowing along shore. Predominately
northwest winds will remain gentle through this period.
