...CHANCES OF SHOWERS/T-STORMS IN THE AFT/EVE THROUGH MOST OF THE 
PERIOD, MAINLY SE CA, THE SIERRA, AND NV...
...ABOVE NORMAL TEMPERATURES FOR MUCH OF CA/NV THE NEXT FEW DAYS 
WITH MORE WIDESPREAD NEAR TO BELOW NORMAL CONDITIONS FRI ONWARD...

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

The pattern remains the same with a strong area of high pressure 
over the Four Corners/TX and troughing offshore of BC/PacNW/nrn CA. 
Areas closest to the trough are expected to see near to below normal 
temperatures the next few days while most of NV and central/srn CA 
experience above normal temperatures (+5 to +15 deg F). By Friday, 
the offshore trough looks to move inland into BC and the PacNW while 
additional troughing expands southward offshore. This should push 
relatively cooler temperatures further across the region for Friday 
bringing more widespread near normal conditions the rest of the 
period.

The other impact of the continued presence of the inland high 
pressure will be mid level moisture and instability rotating into 
the area throughout the forecast period. The exact locations best 
expected to see scattered showers and thunderstorms will fluctuate 
daily, but generally over se CA, parts of the Sierra, and NV 
particularly in the afternoons and evenings.
