... Snow will create slick driving conditions Monday...
A strong fast moving cold front will move through the region
during the day today with slick driving conditions likely in the
Sierra and possible throughout the rest of the region.
In the Sierra snow accumulations of a few inches at all
elevations with up to 5-8 inches along the higher passes will
bring back winter driving conditions to the Sierra. You should
anticipate travel restrictions and delays today and tonight in
In western Nevada, snow showers with light accumulations of snow
around 0.5-1.0" of snow are possible with up to 2 inches in some
A flash freeze will also be possible today where a small amount
of snow falls, melts as it hits warmer ground surfaces, and then
refreezes when the temperatures fall. The most likely areas for
flash freeze will be in the lower valleys in western and west-
central Nevada where the temperatures are expected to rise to the
mid 40s today before cold front arrives. Keep in mind, it only
takes 0.01 of precipitation flash freezing to the Road to make for
hazardous driving conditions, and it is nearly impossible to say
exactly where this might happen.
So the best advice is, if you see precipitation falling or
wet/snowy roads today be extra cautious since they could be even
slipperier than usual.
