...ELEVATED FIRE WEATHER CONDITIONS ON FRIDAY DUE TO A
SLIGHT CHANCE OF THUNDERSTORMS...
.DISCUSSION...
There remains a slight (5-15%) chance for isolated thunderstorms
on Friday along the Sierra crest and portions of NW Shasta County
and Coast Range as monsoonal moisture moves through the area.
Although confidence remains low on any impactful thunderstorm
activity as majority of convection will remain further east.
Otherwise, cooler, breezy, and drier weather prevails on Friday,
with warmer temperatures and slightly lower humidities through the
weekend.
