...Isolated dry lightning and gusty outflow winds possible (10-15%
chance) northern Trinity County mountains this afternoon and early
evening...
.DISCUSSION...Offshore flow continues to bring dry air and breezy
winds to the higher terrain overnight, especially in Humboldt and
Del Norte counties. Hot temperatures in the triple digits are
expected for much of the interior through early next week. Some
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 this afternoon
and a 5-10% chance Monday afternoon.
