  the month, but confidence is low.

.DISCUSSION...

Strong high pressure remains anchored in the eastern Pacific Basin
through the weekend, directing the storm track well north of the
region. As a result, the weather will be dry and mild for most areas
over the next several days. The sole opportunities for showers will
be today and perhaps again around the middle of next week as a
couple weak lows quickly traverse the PacNW states. Best shower
chances (30-60%) today will be confined to N Lassen County, the
Surprise Valley/N Washoe County, and N Pershing County during the
afternoon and evening hours. Winds will also become gusty at times
along Sierra ridges this weekend with gusts reaching 40-60 mph.

Minimal change in the governing weather pattern will maintain our
stretch of quiescent weather into next week. A minor boost in shower
chances is slated for Tuesday into Wednesday, but only to around 10-
20% near the Oregon border. High pressure shifts eastward towards
the region next week, resulting in a warming trend that culminates
in temperatures 15-20 degrees above seasonal norms from mid to late
week. Winter storms will continue to be diverted away from the
region, but there are hints that may change around the middle of the
month.

.AVIATION...

Some light snow showers are ongoing near KWMC this morning but
will dissipate by 15Z this morning. Sporadic light showers will
affect terminals north of KSVE into Saturday. Otherwise,
widespread VFR conditions and light SFC winds prevail into the
weekend. N/NW FL100 winds of 25-35 kts may yield periods of minor
LLWS and mountain wave turbulence today into Saturday for Tahoe
and Sierra Front terminals.
