...CHANCE OF ISOLATED THUNDERSTORMS SUNDAY AFTERNOON FOR MOSTLY ZONE 283...
...CHANCE OF DRY/WINDY CONDITIONS MOSTLY FOR ZONES 283, 277, AND 264...
.DISCUSSION...Chance for afternoon thunderstorms in the Trinity
Horn will continue today due to passing cold front. Winds will
remain mostly terrain driven with modest onshore westerly pushes
each afternoon in exposed areas through Saturday. Stronger onshore
wind is expected with a cold front on Sunday. The frontal passage
on Sunday will likely induce stronger westerly to northwesterly
winds for our typically dry and windy areas; Lake, interior Mendocino
and eastern Trinity.
