.DISCUSSION...through the weekend.

Troughing across the Southwestern US will result in dry
southwesterly flow across southern Nevada, northwestern Arizona,
and southeastern California, which will help dry conditions
persist for through the week for most of the region. The one
exception to this will be the Sierra Crest, where there is around
a 15 to 20% chance for isolated showers and thunderstorms this
afternoon. These low precipitation chances are a result of a a
shortwave off the coast of California shifting inland and
resulting in upslope flow on the windward side of the Sierra. This
upslope flow will provide enough lift for weak showers and
thunderstorms to develop across the crest of the Sierra. Outside
of the Sierra crest the only evidence of this shortwave will be
breezy southerly winds this afternoon.

Increasing 500 mb heights will allow for temperatures to gradually
warm up throughout the week with warmer than normal temperatures
returning during the second half of the week. Temperatures a few
degrees above normal will result in Moderate (Level 2 of 4) HeatRisk
spreading across much of the region over the weekend. This level of
heat will impact anyone without access to proper cooling and/or
adequate hydration as well as heat sensitive individuals. Those
planning on recreating outdoors this weekend should keep an eye on
forecast temperatures and take steps to mitigate adverse heat
impacts (e.g., taking extra water and sports drinks with you,
putting on sunscreen, and wearing light colored and lightweight
clothes).
