...Thunderstorm Risks Rising, Then Another Big Heatwave...

Well if you needed another reminder that summer was indeed here,
the next 7-10 days will provide that. Meandering low pressure over
the region will help increase chances for thunderstorms through
Thursday, followed by an expansive high pressure build-up that
will lead to potentially record-setting temperatures next week.

* Thunderstorms: Isolated storms are possible into this evening.
  While the best chances remain primarily near and east of Highway
  95 in Nevada, a storm or two could form westward near Reno,
  Tahoe, and Carson City. Thursday is on track to be a more
  widespread thunderstorm day for much of the Sierra and Western
  Nevada. Moisture levels will increase into tomorrow such that
  locally heavy rain and flooding are possible from slow moving
  storms over the region. Strong gusty storm outflows could also
  produce localized blowing dust.

* Anyone with outdoor plans the next few days, but especially
  Thursday, should monitor the forecast, try to do outdoor
  activities in the morning, and have a "Plan B" in case storms
  threaten. Given how dry vegetation is, new fire starts from
  lightning are possible. Also expect strong outflow winds, rapid
  temperature drops, and even some hail with these storms.

* All eyes then turn to what could possibly be a major Western
  U.S. heatwave starting Sunday and lasting much of next week.
  Current indications are showing highs into the lower 100s for
  Western Nevada with highs in the 80s to near 90 for mountain
  communities. These could eclipse records Sunday through
  Wednesday. Confidence is high in heat health impacts especially
  for those outdoors for extended periods of time, and for
  vulnerable populations such as the elderly and homeless.
