...Isolated dry lightning and gusty outflow winds possible (10-15% chance)

.DISCUSSION...Offshore flow is expected to bring dry air and breezy
winds to the higher terrain Sunday morning especially in Humboldt
and Del Norte counties. Hot temperatures in the triple digits are
expected for much of the interior through early next week. Relief
from the heat is forecast by mid week, but it is generally expected
to remain hot all next week. Winds are generally expected to
be light and terrain driven aside from the offshore winds overnight.
There is 10-15% chance for dry thunderstorms with gusty
outflow winds over northern Trinity County mountains on Sunday
and a 5-10% chance on Monday.
