.KEY MESSAGES...
* A series of disturbances will roll through the Western US this
  week, bringing isolated showers to the Great Basin and breezy,
  dry conditions to the rest of the region.
&&
.DISCUSSION...through Sunday.
The first in a series of shortwaves will approach the West Coast
today, rolling through the Great Basin tomorrow. This first
disturbance will bring a 20 to 40% chance of isolated showers and
thunderstorms to the eastern Sierra and southern Great Basin today
and tomorrow, with breezy 15 to 25 mph wind gusts across the region
each afternoon. As this system rolls through, we will find ourselves
under southwesterly-to-westerly flow aloft, which will help flush
moisture from the region. A cut-off low will push into the Pacific
Northwest later this week, before opening up and digging south into
our forecast area. While there remains uncertainty regarding the
timing and strength of this trough, we can expect breezy winds and
cooler conditions to accompany it. These cooler temperatures look to
stick around as long-term guidance shows this trough-y pattern
continuing through the weekend and into early next week.

20 knots are more likely tomorrow, generally between 30/18Z and
