.SHORT TERM...Today though Friday night...Operational model
guidance is in good agreement through the short term with minimal
weather concerns. A rex block will persist off-shore with dry
northwesterly flow early Friday. Scattered cirrus will continue to
spill over the ridge with plenty of filtered sunshine with daytime
highs 8 to 10 degrees above climatology for this time of year.
Mostly clear, calm and lengthening nights will allow for efficient
radiational cooling and yield overnight lows values more typical
of late September, although not quite as cold as the last few
nights. As the low portion of the rex block approaches the
northern CA/southern OR coast Friday night will see some more
substantial upper level cloudiness beginning to filter in under
southwesterly flow but the forecast remains dry. Peck

.LONG TERM...Saturday through Tuesday. A dry ridge of high pressure
should influence the regions weather with above normal temps into
Saturday before an upper level low pressure system drifts into the
pacnw Saturday night and Sunday. Moisture was associated with the
system and some showers are expected to develop over portions of the
region especially over the area mountains. Tie low moves rapidly
east Sunday night with a brief break before another system effects
the area Monday and a third on Tuesday. Temperatures should return
to near normal Sunday and into next week.

.AVIATION...vfr conditions will continue for the next 24 hours
across all taf sites.
