...Isolated Showers and Thunderstorms Today, Warm Temperatures
Through Monday...

Thunderstorms Today:

* Showers and thunderstorms will develop across the eastern Sierra
  today and spread northward across the Tahoe Basin during the
  afternoon. A few showers and storms will also develop across
  western Nevada and gradually move towards the north through the
  early evening hours.

* Hazards with these storms include, a mixture of wet and dry
  lightning strikes leading to possible new fire starts, and
  gusty/erratic outflow winds. Outflow winds from thunderstorms
  are capable of capsizing small vessels and reducing visibility
  due to blowing dust. Flash flooding caused by locally heavy
  rainfall on local burn scars cannot be ruled out.

* Stay aware of weather conditions and have a way to get weather
  alerts, especially if you are recreating outdoors. Monitor the
  clouds, and if clouds are developing vertically, it is time to
  end your activity and prioritize retreating indoors. If you hear
  thunder while you`re on the lake or miles into a hike, then you
  have already waited too long to seek shelter. Stay away from
  recent burn scars as heavy rainfall can create dangerous debris
  flows.

Heat Through Monday:

* Warming trend continues through Monday. While nothing too
  unusual for late June, high temperatures will run 5 to 10
  degrees above average with mid to upper 90s across lower
  valleys and 80s in the Sierra valleys. By Monday, many western
  Nevada valleys will flirt with the 100 degree mark.

* Most areas will see low to moderate heat risks for sensitive
  populations. Consider reducing, canceling or rescheduling
  strenuous activities to the coolest time of the day. Individuals
  at risk should stay in the coolest available place. Drink plenty
  of fluids to stay hydrated and never leave children or animals
  in a vehicle.
