.DISCUSSION...

Winds today will be much lighter than yesterday, as we see a few
lingering clouds on the back side of the recent trough that brought
all the wind concerns. Winds gusts today will range around 10 mph
across western Nevada valleys, with ridge gusts roughly the same, up
to 15 mph. Another noticeable change is the cooler than average
temperatures for today. Lower valleys will see mid to upper 70s
while Sierra valleys will see lower 70s.

We see temperatures rebound back into the low 80s across western
Nevada with mid 70s to low 80s for Sierra valleys. Winds will be
similar to today for Friday. Saturday highs will climb to mid to
upper 80s for lower valleys and lower 80s for Sierra locations.
Winds for Saturday will start to see a slight increase for Saturday,
ahead of our next system to arrive Sunday. Winds will increase
overnight Saturday into Sunday, bringing back ridge gusts of 40-45
mph. As Sunday progresses, we anticipate gusts to increase through
Sunday evening, reaching 55+ mph by afternoon. Additionally, rain
showers will fill in from the northwest, bringing chances of 50-70%
north and along I-80, 30-50% in and around the Tahoe Basin, Alpine
and Mono counties, and 25-40% for the Basin and Range.

The wet pattern will linger into Monday, with hints of colder air
dropping snow levels, bringing a non-zero chance for rain, maybe
even snow on the Sierra ridges. Confidence is on the low end for the
snow at this point, considering how warm we have been recently. On
the other hand, this trough does appear to dig rather far south,
signaling a potential for a shot of colder air overnight Sunday into
Monday. Overnight lows nearing the mid 40s appear over the western
Nevada valleys, and Sierra valleys can expect near freezing
temperatures early Monday morning. Looking into midweek and beyond,
the showery weather remains in the long range, with cooler
temperatures settling in for the duration. Fall, is that you?
