...Unseasonably Warm Temperatures and River Rises From Snowmelt
Expected Through The Weekend...

* The warmest temperatures so far this Spring are expected to
arrive this weekend, with afternoon highs up to 20 degrees
above-average for late April. By Saturday, mid-to-upper 80s are
expected across much of western Nevada, with 90 degrees not out
of the question for portions of the Basin and Range. If
recreating or spending time outdoors, be aware that it will be
unusually hot for this time of year and prepare accordingly.

* These warm temperatures, along with mild overnight lows, will
result in efficient melting of our snowpack. Consequently, high
river flows are anticipated across much of the region. Water
will be swift moving and frigid, so be cautious if approaching
a river bank. With snowmelt-driven river rises, daily
fluctuations are common and it`s possible the peak flows will
occur overnight. Keep this in mind when setting up camp near the
water.

* A return to cooler, more unsettled weather with the chance of
mountain snow showers and valley rain and/or thunderstorms will
be possible much of next week. Stay tuned to the forecast for
updates on this early May pattern change.
