.DISCUSSION...Isolated thunderstorms are possible again today,
especially across northern Inyo County and Central Nevada, with a
lower chance across portions of eastern San Bernardino and Mohave
Counties where moisture from the remnants of tropical storm
Juliette streams over the region. Lightning strikes and erratic
gusty winds are expected with any storms that develop. Isolated
thunderstorm potential continues Friday across northern Inyo
County and Central Nevada, though a warming and drying trend will
see RHs drop to around 15-25% by Friday afternoon, and under 20%
this weekend onward with fair to good nocturnal recovery.
Note: Thunderstorms imply gusty and erratic winds.
