National Weather Service Reno Nevada
258 am PST sun Nov 23 2014


Seasonably cool conditions today will be followed by a warming
trend to well above normal temperatures by middle-week as high
pressure over the Pacific builds into northeast California and
western Nevada.


Short term...

A dry forecast with light winds (at least for valleys) is in
store for northeast California, the eastern Sierra and western
Nevada through Tuesday night as an upper ridge slowly strengthens

At the low levels, a seasonably cool airmass building into the
Great Basin today will remain in place on Monday with only a
slight uptick in high temperatures as the airmass slowly modifies.
On Tuesday, highs jump more significantly for many areas as
subsidence warming aloft under the building ridge works down into
the valleys. Snyder

Long term...Wednesday through Saturday...

No significant weather impacts to travel are expected as the
Thanksgiving Holiday begins. Ridge axis is expected to slowly
drift east and flatten, resulting in areas of high clouds spreading
over the region but no precipitation Wednesday or Thursday.
Wednesday should be the warmest day of the week for most areas
with highs pushing above 60 degrees in some valleys, then slightly
cooler on Thursday as the ridge begins to weaken.

By Friday, the next low approaches the California coast but it is
showing signs of pinching off, resulting in the ridge amplifying a
bit over the Great Basin. Highs should remain above normal over
most of the region, except thicker clouds spreading across
northeast California-northwest Nevada could keep those areas a few degrees

For next weekend, the latest medium range guidance keeps the main
low off the California coast, but breaks off a shortwave which moves
inland across northern California with increasing Pacific moisture. This
could lead to some rain and high elevation snow by Saturday for
the Sierra mainly from Tahoe northward to northeast CA, with
lighter rain possible across parts of western Nevada. A major
precipitation event is not expected from this weather system, and
snow levels are likely to remain rather high since the core of the
low stays offshore. Mjd



VFR conditions with generally light winds through Monday. Only
exception is patchy fzfg around ktrk this morning which should
disperse by 15z as high clouds increase. The potential for fzfg at
ktrk is lower for early Monday morning, but could still form if
enough clearing occurs after 08z. Mjd
