As we suffer the lack of substantial rain here in CA, I recall my naieve new-to-CA weather expectations: CA is always sunny (never cloudy), doesn't rain, never snows.
TV& movie fantasies apply only (if at
all) to Socal/L.A. &; desert points-east (bordering AZ.) The 56mi. L.A. River is more than just a trickle in an urban cement channel.
Way up here in Norcal/SF Bay, it gets cold (below freezing) overnight,
rains, snows (on mountain peaks, rarely down in the
valley.) Rain supports agriculture & increasingly populous cities. Microclimates
(S.F., the central coast, etc.) reduce weather zones to smaller
regions than I 'd ever imagined & certainly never heard of 'back
east'. Drought - which I thought was perennial all over CA - except the coast - is not only regional but macro-cyclical. (We're currently in the 7th-year of the latest.)
For me, it's all become unexpectedly informative (so far.)
