...ABOVE NORMAL TEMPERATURES AND DRY CONDITIONS THROUGH THE PERIOD...

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

A strong upper ridge continues to drift eastward across the west
coast bringing warm and dry conditions to the region. Expect
temperatures to gradually rise the rest of the week as the ridge
moves overhead. This will usher in dry air and increase
temperatures. Expecting widespread temperature anomalies of +5 to
+15 deg F and locally up to +20 deg F with these peaking over the
weekend. Models still have a weak low approaching into Sunday, but
have weakened it further into a shortwave moving through later
Sunday into Monday. This makes showers less likely, though still
possible. The det GFS is still showing a few showers as are some of
the ECMWF ensemble members, however, elected to keep the official
forecast dry for now in line with WPC and the NBM. Aside from this
trough, the ridge will dominate the weather pattern for some time.
CPC outlooks continue to show strong chances of above normal
temperatures through mid October.
