Area Forecast Discussion
National Weather Service Reno NV
129 PM PDT Sat Apr 20 2024

.SYNOPSIS...

Well above normal temperatures and dry weather will continue into
Sunday and Monday. A pattern change will unfold starting Tuesday
with low pressure developing along the west coast. Cooler
temperatures along with isolated showers are forecast Tuesday
through Thursday, with more widespread showers and mountain snow
showers for next Friday.

.DISCUSSION...

* Presuming today is RNO`s first 80 of 2024, that`s right on
  schedule with the average since 1990 of April 22nd. After an
  "unusually normal" winter snowpack, now a normal first-80. How
  about that...

* Even warmer temperatures projected for tomorrow and Monday.
  Will take some getting used to for sure. Probably time to turn
  the irrigation on. With plentiful sunshine and above freezing
  temps at night for many areas, snowmelt will remain robust
  leading to cyclical rises on streams and rivers. No flooding
  concerns at this point, but take care around that fast & cold
  water.

* Pattern starts to change Tuesday onward with more troughing
  along the west coast taking shape. Cooling aloft will help
  generate isolated showers and possibly t-storms Tuesday,
  Wednesday, and Thursday - each afternoon and evening. If I had
  to pick a day next week where rain is most likely, that`s
  Friday, when most global models bring a more meaningful trough
  through the region. 20-40% odds of a wetting rain of 0.1" in W
  Nevada and foothills, and 20% chances for 2" or more of snow in
  the mountains above 6500` with falling rain-snow lines.

* Simulations into the following week of April 28th remain
  unsurprisingly variable with regard to temperatures which are
  showing large spreads. Not seeing any big storm signals but
  showers cannot be ruled out.
