Synopsis Building high pressure near the west coast will
maintain dry weather through next week. A gradual warming trend
will continue through midweek.

Discussion As of 8:55 pm pdt Saturday... A warming trend got
underway today as northerly flow brought a drier airmass into the
region. Afternoon highs were generally 5 to 9 degrees warmer than
yesterday and were mostly in the 70s, except some low to mid 80s
inland. Most locations posted highs that were a few degrees warmer
than normal.

Not much change is expected going into Sunday. The airmass aloft
is forecast to warm a few degrees c as an upper trough over the
great basin continues moving to the east, while an upper ridge
offshore edges closer to the coast. Also, light northerly flow
aloft will continue to bring dry air into the region, which will
result in another day of clear skies across our entire region.

Although temps will start of relatively cool again, with early
morning lows in the 40s for most valley locations, high
temperatures on Sunday are forecast to be about 3-5 degrees warmer
than today.

The models agree that that the upper ridge offshore will continue
to build gradually eastward and over the west coast through the
middle of next week. 850 mb temperatures are forecast to climb
from their current value of about 11 degrees c to around 20 deg c
by midweek. In addition, light offshore flow is expected to
persist through at least Tuesday. The result will be a continued
warming trend region-wide through midweek. High temperatures will
be relatively uniform across the region due to light offshore
flow. Highs by Tuesday and Wednesday will be mostly in the 80s
except 70s very close to the ocean and lower to mid 90s in some of
the warmest inland areas. Even a slight increase in offshore flow
could easily result in downtown san francisco reaching 90 by
Tuesday or Wednesday. Because of the longer autumn nights and dry
airmass, we will continue to see relatively good overnight cooling
through the week ahead, which will help mitigate heat risks due
to elevated daytime temperatures.

Slightly cooler weather is projected to develop by late next week
as the upper ridge axis shifts inland and light onshore flow
develops. Even so, temperatures are expected to remain warmer than
normal.

Aviation As of 10:29 pm pdt Saturday... Light winds andVFR.

Patchy ifr CIGS are possible over the monterey bay early Sunday
morning.

Vicinity of ksfo...VFR.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR. Patchy ifr CIGS are possible around
sunrise.

Fire weather As of 5:00 pm pdt Saturday... A warming and drying
trend is forecast to continue into early next week as high
pressure builds over california. Relative humidity values will
drop into the teens during the afternoon hours while overnight
humidity recoveries will only reach about 30 percent in the higher
hills. In addition, light to moderate northerly or offshore winds
are forecast to continue in the hills. Strongest winds are
expected over the north bay hills where critical fire weather
conditions are anticipated. A red flag warning is in effect
through Tuesday morning for elevations above 1000 feet in the
north bay hills. Locally gusty winds are expected elsewhere in
the hills, particularly in the east bay hills. Warm and dry
conditions are forecast to persist through next week, although
winds in the hills will likely diminish after Tuesday.

Marine As of 10:13 pm pdt Saturday... Northwesterly winds will
be gusty over the northern waters while winds over the remaining
waters and bays remain light tonight. Surface high pressure
situated offshore will also periodically build across northern
nevada through early next week. A northwest swell train will
arrive by the middle of next week.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
