What? A long-term forecast?

Postby Bulldog » Sun Sep 09, 2007 9:38 pm

It's pretty rare for NWS to go this far out on a limb, so they'll probably be wrong, but it's a nice idea...
Long term...
medium range models continue to forecast the Rex-like cut-off low
over the eastern Pacific vicinity of 130w to bust into the ridge over the West
Coast later this week with a significant cooling trend and possibly
a couple of periods of unsettled weather. Rather good agreement in
timing and location of upper trough between the European model (ecmwf)/GFS for 144 hours
12z Sat when the system moves inland...with the European model (ecmwf) just a tad
faster. Onshore flow expected to increase...with rather strong Delta
breezes Thursday-Sat with maximum temperatures returning to normal or below normal
through this period.
This is also expected to spread some marine
stratus inland...and into portions of the Interior Valley. After Sat...
temperatures expected to rebound slightly as the upper trough moves east of the
area...and flow turns northwesterly on Sunday. We expect to see some initial
cooling through the Delta area on Wednesday.

It says 10M, but it's really a 9.
