Friday December 4
We have an abundance of precipitation that will literally
saturate the great PNW and, yes, portions of California
between now and Christmas. You may have noticed the
heavy rain already.
The upper level steering winds are - on average - pointed
right at the PNW, driving multiple storm systems directly
into the PNW. The storm centers will be spaced approx
24-36 hours apart. The moderate-to-heavy rainfall associated
with each of these powerful storms will set up flood issues.
Everyone from northern CA to Vancouver Is. must pay close
attention to Nat'l Wx Service watches posted over the next
Mountain snow fall will be measured in FEET, esp in the later
series of storms. The snow line will progressively drop to lower
& lower elevations as a colder air mass approaches the PNW. In
fact, coastal mountain, foothill & low elevation snow may come
into play later next week.
The WET pattern, with abundant mountain snow, will continue
well into the weekend before Christmas. Water managers will
also be able to pause their concern for irrigation issues next
summer. True, we have a long way to go, but no question about
the abundance of precip - both rain & snow - during December
will be favorable; northern California included.
