Area Forecast Discussion
National Weather Service Sacramento CA
913 AM PST THU FEB 4 2016

.SYNOPSIS...
A weak weather system may brush far northern California with light
showers Friday night. Otherwise dry weather expected through at
least the middle of next week. Near normal daytime temperatures
today with above to well above normal temperatures through next
week.
&&

.DISCUSSION...
Ridge of high pressure begins to build over the area today and
will remain in control through the weekend. A weak wave attempts to
enter NorCal later Friday into early Saturday but any moisture
should remain shunted to the north. Outside of a few showers
across northern Shasta county, dry weather will rule into early
next week. Building ridge will allow for warming temperatures with
readings into the 60s and 70s by Sunday and Monday. Some patchy
valley fog possible each morning into the weekend.

the San Joaquin Valley Tue and Wed after northerly winds slow.
The next series of waves knock on the door beginning Thu night
into Fri.         JClapp
