area forecast discussion
national weather service sacramento ca
235 am pdt Wed sep 19 2018

Synopsis
Warmer weather continues into next week. Enhanced fire weather
concerns tonight and Thursday. Patchy smoke and haze will persist,
mainly locally over northern portions of shasta county.

Discussion
A few high clouds are moving across the far northern portion of
the state associated with the passing weak trough. Otherwise,
skies are clear across the region. Current temperatures are a tad
warmer compared to 24 hours ago across most of the area and range
from the 30s in the mountain valleys to the mid 50s to mid 60s
across the central valley.

Upper level ridging strengthens the remainder of the week
resulting in warmer temperatures with daytime highs returning to
average, or slightly above average.

Locally gusty northerly winds will develop across portions of the
sacramento valley and surrounding terrain tonight into Thursday
with the strongest winds expected Thursday. The warmer
temperatures and northerly winds will lower humidity levels over
the northern and northwestern portion of our forecast area. This
has increased fire weather concerns, and as such a fire weather
watch has been issued for this time period. Winds are expected to
subside by Friday.

.Extended discussion (Sunday through Wednesday)
the upper trough over the pacific northwest will shift east
toward the northern rockies on Sunday, with possibly northerly
flow developing across northern ca Sunday or Monday.

Both the GFS and ECMWF are converging on a solution with a rex
block pattern developing over the eastern pacific next week, as a
closed upper low becomes embedded within a large scale ridge.

Confidence is increasing that northern california will remain
under strong subsidence early next week. As such, dry weather is
likely to continue through the extended period. We have warmed
forecast temperatures several degrees early next week, reflecting
the growing confidence in this ridge pattern. Dang

Aviation
Vfr conditions the next 24 hours except for local MVFR ifr due to
smoke near the delta fire. Light winds across valley terminals
will become north 5-15 kt later today and tonight. Dang

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.
