...HIGH PRESSURE WILL CONTINUE TO BRING ABOVE NORMAL TEMPERATURES 
THROUGH THE WEEKEND WITH SOME MODERATION EARLY NEXT WEEK...
...MONSOONAL MOISTURE TO BRING CHANCES OF SHOWERS/T-STORMS ACROSS 
PARTS OF THE SIERRA, SE CA, AND SRN NV...

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

A strong area of high pressure remains over the Four Corners 
resulting in widespread above normal conditions across the region. 
This will continue to be the main driver of the weather through at 
least the weekend. Afternoon high temperature anomalies are expected 
at +5 to +15 deg F. In addition to continued heat, the ridge over 
the Four Corners is forecast to rotate mid level moisture and 
instability over parts of CA/NV through at least early next week. 
This will result in areas of showers and thunderstorms. Best chances 
are across the central/southern Sierra, se CA, and southern NV.

Low pressure over the Gulf of Alaska may generate some weak 
troughing offshore off the PacNW and nrn CA coasts early next week 
as well, finally allowing for some moderation of these afternoon 
high temperatures. 500 mb height clusters still favor high pressure 
surrounding that area of troughing through mid week before positive 
anomalies ease and some troughing takes hold at the end of the 
forecast period.

Freezing levels remain high as well at over 16 kft. This will hold 
true through early next week before some decrease down to about 15-
16 kft or so into early Wednesday.
