...Next Storm Brings Strong Winds but Not Much Rain or Snow...
The next in a series of storms is projected to impact the region
Wednesday afternoon through Thursday, with a weaker system
brushing across the region Friday morning. This storm has a good
amount of wind energy with it, but is relatively warm and moderate
at best in terms of precipitation potential. Here are the key
* Timing: Strong south/southwest winds developing along the
mountain ridges Wednesday, becoming strong in valley locations
areawide by pre-dawn Thursday morning and lasting through the
afternoon Thursday. Periods of light to moderate rain affecting
the northern Sierra and northeast California Wednesday evening
into Friday morning. Snow levels will generally remain above
7500-8000 feet but may temporarily lower to near 7000 feet
Wednesday night and again early Friday morning. Western Nevada
and the eastern Sierra in Mono County are likely to see minimal
* Impacts: Strong winds Thursday may create travel problems in
wind prone areas, strong turbulence for aviation, localized
power outages and tree/fence damage, and impacts to any open ski
areas. Rapid fire spread is possible in lower elevation grassy
vegetation. Light snow accumulations could result in travel slow
downs over Sierra passes, with the highest risks Thursday night
into Friday morning.
* Confidence: High confidence that we`ll see a storm Wednesday
through Thursday. Medium but increasing confidence in wind
intensity, precipitation amounts, and rain-snow line elevation.
Some fluctuations in forecasts remain possible. Sierra passes
above 7500 feet have the greatest risk of snow impacts.
* What Can I Do Now? Plan for strong winds by securing outdoor
objects, trash cans, canopies, and construction equipment by
Wednesday afternoon. If you have travel plans around the region
Thursday into Friday, anticipate some delays due to wind and/or
light mountain snows. Double check your chains and winter
travel supplies. There could be some delays for flights
departing Reno or diversions of incoming flights Thursday
morning if strong winds materialize.
The upcoming weekend looks overall pretty decent with seasonable
temperatures and light winds. Another low-moderate end storm
remains possible late Sunday night through Monday evening. This
storm is trending colder and has a greater risk of snow impacts
for mountain roads Monday, along with another region-wide bout
with strong winds.
