...WEAK SYSTEM WITH SCATTERED LIGHT PRECIP EAST-CENTRAL NV TODAY...
...MAINLY DRY WITH MODERATE TEMPS INCREASING INTO NEXT WEEK...

.METEOROLOGICAL CONDITIONS (TUE AM - MON AM)...

A broad upr low is situated over the Gulf of Alaska...while an upr 
ridge is centered to the southwest of the region close to 30N/140W. 
Along the west coast...a weak disturbance is moving inland across 
CA. This feature will bring the potential for some scattered light 
precip mainly over east-central NV this afternoon into the early 
evening hours. 

Then for Wednesday into Thursday...the cool system over the Gulf of 
Alaska will make its way toward BC and the Pacific Northwest with 
precip spreading across the region. The southern extent of precip 
will reach down toward the upper Klamath River basin with some 
scattered hundredths of an inch possible. Bigger story will be the 
temporary moderation of temperatures expected for the end of the 
week. 

As this system moves over the interior...high pressure over the 
eastern Pacific will nudge toward the west coast and spread inland. 
This will allow temperatures to increase once again to well above 
normal for much of the region.
