.KEY MESSAGES...

* Light showers ongoing near the Oregon border will continue
  through tonight with periods of gusty winds along Sierra ridges.

* Dry and mild weather prevails elsewhere through much of next
  week.

* A more unsettled weather pattern may emerge around the middle of
  the month, but confidence is low.

.DISCUSSION...

A ridge remains parked over the eastern Pacific Ocean, deflecting
any storms to our north that swing by. A couple of storms will pass
by to our north between today and Wednesday next week. Then towards
the end of the week, that ridge will finally start to breakdown
and move east, allowing the storm track to shift further south.

These shortwave troughs riding around the edge of the high pressure
will deliver northern Washoe County, Surprise Valley, northern
Lassen County, and Pershing County a 30-60% chance of light rain
showers this afternoon and evening. The next round of showers in
those same areas look to be around Wednesday.

High temperatures will gradually warm up each day through this
weekend and into next week, eventually bringing high temperatures
into the 60`s in lower valleys and Sierra valleys by Wednesday.
Winds will stay light (<20 mph) through at least Wednesday next
week, though ridgetops could see gusts up to 35-50 mph through
tomorrow.

Next weekend as the ridge breaks down, we will likely be in for a
pattern change with more active weather. Around 50-60% of the ECMWF
Ens and GEFS members show signs of precipitation arriving during
that time. We`ll monitor as it gets closer.
