...SCATTERED SHOWERS/T-STORMS EASTERN NV AND SOUTHEAST CA THU/FRI...
...BETTER CHANCES FOR SHOWERS/T-STORMS SAT-TUE FOR THE SIERRA...

.METEOROLOGICAL CONDITIONS (THU AM - WED AM)...

Strong high pressure continues over the interior of the country with 
the axis of this feature generally over the Plains states. At the 
same time...a weak area of low pressure continues to spin off the 
Pacific Northwest coast. This has brought generally drier southwest 
flow to the majority of the region with the exception being eastern 
NV and southern CA where moisture remains elevated with PW values 
hovering above 1.00-inch. For today and Friday...look for the best 
opportunity for showers and thunderstorms to be across the eastern 
third of the region.

Through the upcoming weekend into early next week...high pressure 
will continue to hold strong downstream of the area...while weak 
troffing just off the west coast elongates. This overall setup will 
turn flow a bit more southerly and allow for higher moisture content 
air to start advecting northward. Precip chances will return to the 
Sierra...mainly the southern and central portions of the range...as 
well as much of NV. 

Freezing levels remain relatively constant through the 
period...fluctuating from 14000- to 17000-feet with the lowest to 
the northwest and the highest to the east.
