...MOSTLY DRY CONDITIONS ASIDE FROM OCCASIONAL LIGHT SHOWERS ALONG 

THE NRN CA/NV BORDERS, E NV, AND THE CNTRL/SRN SIERRA AS SYSTEMS 

PASS TO THE NORTH...

.METEOROLOGICAL CONDITIONS (SUN AM - SAT AM)...



As expected, scattered showers and thunderstorms formed yesterday 

afternoon across parts of the Sierra and over NV. Observations 

generally reporting 0.10" or less resulting from these showers with 

locally amounts closer to 0.25-0.50". This morning, a troughing 

pattern remains over the western U.S. as an upper ridge sits between 

a pair of upper lows over the eastern Pacific. The region will 

remain under a troughing pattern the rest of the week as some 

disturbances pass through the PacNW. Still no threat of widespread 

organized precipitation, but some passing systems may result in 

occasional light showers over the nrn CA/NV borders, eastern NV, and 

over the central/southern Sierra along with isolated thunderstorms 

depending on the path some of those systems ultimately take. This 

will also keep afternoon high temperatures near to below normal for 

the majority of the region throughout the forecast period. Models 

agree on the overall weather pattern of troughing over CA with 

disturbances moving through the PacNW, but disagree on some of the 

details. 



QPF for the next 6 days predicted to be fairly minimal at 0.10" or 

less with locally higher amounts possible under any developing 

convection. Freezing levels generally 10-13 kft across the region 

with occasional lowering to 5-8 kft across far nrn CA/srn OR and nrn 

NV as systems pass to the north.
