* Thunderstorm coverage will decrease today, before widespread
  showers and thunderstorms return for Saturday through Monday.
  The greatest chances (60%) for storms today will be near the
  Oregon border, with a 10-30% chance elsewhere. Chances increase
  to 50-80% Saturday through Monday for any given location in the
  Sierra, northeast CA, and western Nevada to see a thunderstorm.

* Main threats include frequent lightning, heavy rainfall, up to
  nickel size hail, and erratic wind gusts up to 50 mph, which
  could bring areas of blowing dust. Thunderstorms could generate
  flash floods, especially near recent burn scars. If a nearby
  stream rises quickly or the water becomes turbid with mud or
  debris, get to higher ground immediately.

* If you have outdoor plans be sure to have a "plan B". Make sure
  to have a way to seek shelter within a sturdy building in case a
  thunderstorm forms nearby. If you do not have access to a sturdy
  building, a hard-topped vehicle with the windows rolled up is a
  good option for protection from lightning. Complete outdoor
  activities in the morning before afternoon and evening
  thunderstorms develop.
