...CHANCE OF THUNDERSTORMS FRIDAY AFTERNOON FOR MOSTLY ZONE 283...
.DISCUSSION...Chance for afternoon thunderstorms will continue
through Friday. Storms will likely be wet, though isolated fire
starts will still be possible with dry strikes on the periphery of
rain cores. Storms will most likely produce locally heavy rain
and hail Friday. Outflow wind gusts from 30 to 50 mph will also be
possible. Winds will mostly remain terrain driven with modest
onshore westerly pushes each afternoon in exposed areas through
Saturday. Stronger onshore wind is expected with a colder trough
on Sunday. This trough will also bring another chance of showers
and thunderstorms to mainly the Klamath Mountains on Sunday.
