area forecast discussion
national weather service sacramento ca
332 pm pdt Mon sep 25 2017

Synopsis
Breezy north winds next few days for increased fire danger through
Wednesday morning. Remaining warmer than normal through the end
of the week with lighter winds.

Discussion
Satellite imagery indicates generally clear skies as a strong
upper level ridge builds over interior norcal. Current
temperatures are running 3 to 6 degrees warmer compared to 24
hours ago. The strengthening high pressure system will keep stable
conditions and above normal temperatures across the forecast
area. Temperatures will continue to trend upward each day as
ridging strengthens and shifts inland. Overall, daytime highs
could be up to 5 degrees above seasonal normals through the short
term period with valley highs topping out in the low 90s by the
middle of this week.

A combination of dry northerly flow, low afternoon minimum
humidity, and poor overnight recovery will maintain red flag
warning conditions through Wednesday morning. Winds are expected
to decrease by Wednesday afternoon as the upper ridge axis centers
over the west coast and surface gradients relax.

.Extended discussion (Friday through Monday)
an upper level trough is expected to displace the high pressure
system starting Friday. Current model runs trending toward a
deeper, faster moving trough that will sweep through the area
Friday and Saturday. Slight cooling expected with this trough as
valley temperatures may fall back into the 80s, though have not
yet brought temperatures as low as models suggesting due to the
uncertainty of the situation. Upper level ridging builds up again
Sunday allowing valley temperatures to rise back into the 90s.

Models diverge even more after Monday as the ECMWF and canadian
models bring a shortwave trough through the area on Monday,
whereas the GFS shows the shortwave remaining well east. For now,
no precipitation is expected with these systems as it will remain
north of the area. Strong northerly winds will set in Sunday after
the trough passes as the ridging builds over the west coast once
again. Hec

Aviation
Vfr conditions expected for valley TAF sites for the
next 24 hours. Northerly gusts up to 20kts possible in the
sacramento valley today 18-02z. Easterly gusts up to 30kt possible

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. 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.
