Wider weather episode

Light Sierra snow showers and gusty winds returned on the 19th. A fast moving low pressure system provided a round of light snow showers across the northern Sierra along with gusty southwest winds across western Nevada. The main wave of snow showers moved along the northern Sierra crest early in the afternoon of the 19th with snow levels around 5500-6000'. Snow accumulations were projected to be spotty due to the convective nature of the snow along the incoming cold front. Overall, winds were the main impact with this storm with afternoon wind gusts expected to reach around 30-40 mph for most areas as Sierra ridgetop gusts exceeded 80 mph. This resulted in choppy lake waters and aviation turbulence. Strong crosswinds for high profile vehicles were expected along Hwy 395/I-580 with these gusty winds pushing out into the Basin and Range during the afternoon, impacting area highways including Hwy 95 near Walker

Lake.
