Area Forecast Discussion
National Weather Service Reno NV
226 PM PDT Fri Oct 20 2017


Brisk breezes and a few light showers towards the Oregon border
will continue into the evening hours before drier air moves into
the region overnight. Another quick shot of light snow is possible
Saturday morning for the Surprise Valley area from a passing
wave. Otherwise, dry and warmer conditions are expected this
weekend and next week as temperatures warm well above seasonal



No major adjustments were made to the existing forecast. A weak
wave will strafe the Oregon border Saturday bringing chances of
light snow showers to very northern Lassen County and the Surprise
Valley. Accumulations will be much lighter than last night`s
totals for Cedar Pass and the Cedarville area.

Winds shift easterly with generally poor mixing expected later
this weekend. This could impact any planned prescribed burns as
high pressure settles over the region. Valley locations will
likely experience stronger thermal inversions and an uptick in low
level air quality degradation.

Then the trend will be for drier and warmer conditions as high
pressure builds across the region Sunday onward. Stronger valley
inversions may slow the warming trend more than is currently
forecast, but highs warm significantly by early/mid next week.
High temperatures may approach daily records for some locations.



After some lingering mountain obscurations tonight and Saturday,
conditions dry out. Expect VFR for area terminals with some
showers towards the Oregon border through Saturday morning.

Nocturnal inversions strengthen by Sunday and may result in areas
with MVFR visibilities due to morning fog formation. This will be
mostly likely for KTRK where morning fog is typical. Boyd
