...WARM AND DRY PEAKING THURSDAY OR FRIDAY...
...A SHOWER NEAR THE CREST OF THE SRN OR CASCADES FRI PM/SAT AM...
...RETURN TO WARMING NEXT WEEK IS POSSIBLE...

.METEOROLOGICAL CONDITIONS (WED PM - TUE AM)...

Temperatures heating up again early this afternoon under strong high 
pressure centered over southern CA. Look for another day of several 
record high temperatures to be set once again...and as this event 
peaks either Thursday (March 19) or Friday (March 20) with anomalies 
of plus 15- to plus 30-degF over seasonal normals there may be some 
locations that see all-time record March high temperatures.

In terms of precip...the only chance will be a shower or two across 
the crest of the southern OR Cascades late Friday into early 
Saturday as a s/wv trof moves across southern BC and the Pacific 
Northwest and sags a weakening cold front and eroding moisture plume 
toward the CA/OR border. Otherwise...dry conditions will be the rule.

Into the extended...models are slowly trending away from the idea of 
a weather system moving across the area next week Tuesday into 
Wednesday...and now showing a strengthening upr ridge once again 
centered over southern CA drifting toward the Desert Southwest. This 
could potential bring a renewed increase in temperatures to 
well above normal across the region Tuesday and Wednesday.
