.DISCUSSION...

As of this writing, light snow showers continue to impact Mammoth
and portions of Mono and Mineral counties. The low pressure
system bringing said showers will continue to drop south early
this morning, which will help taper any lingering showers that
make it past daybreak. Amounts are expected to be light (an inch
or less) though impacts may include slick roads ahead of the
Friday AM commute.

Coinciding with mornings past, there`s a chance for patchy
(freezing) fog across Sierra and W NV valleys again this morning.
This will bring visibility reductions and slick roads, especially
over bridges. Take it slow, leave plenty of space, and use your
low-beams.

Besides a very light (~10%) chance of showers along the OR border
late Sunday, dry conditions prevail through the majority of the
week. Afternoon highs will be in the 50s and 40s for valleys and
high elevations, respectively, with overnight lows below freezing
across much of the area. Travel ahead of the Thanksgiving holiday
looks to behave itself with said dry conditions continuing. The
weekend after, though, may throw a wrench in travel plans,
depending how far west the trough drops. Check back here for
details as we get closer.
