area forecast discussion
national weather service sacramento ca
331 am pdt Mon sep 25 2017

Synopsis
Warmer through mid week with dry conditions continuing. Breezy
north winds next few days for increased fire danger. Remaining
warmer than normal through the end of the week with lighter winds.

Discussion
A strong upper level ridge of high pressure will bring continued
fair skies and above normal temperatures through the short term
period. The overall airmass is forecast to warm a few to several
degrees today, Tuesday and a bit more Wednesday as the ridge
amplifies and shifts inland. Combination of northerly flow aloft
and northerly surface gradient will bring breezy north winds today
especially over the northern portion of the cwa. As surface high
pressure pushes into the great basin on Tuesday the easterly
surface gradient tightens over the sierra bringing increasing
winds there. Winds and low daytime rh as well as poor overnight
humidity recovery will bring increased fire danger through Tuesday
night. Lighter winds are in store Wednesday as the upper ridge
axis centers over the west coast and surface gradients relax.

Little change in forecast expected for Thursday as upper level
pattern remains mainly unchanged.

.Extended discussion (Friday through Monday)
eastern pacific ridging will remain over the area with dry and
warm weather continuing through the week. Daytime highs will
remain above normal with low 90s across the valley, delta and
into the lower foothills. By Friday, the ridge will slowly be
displaced as a trough moves into the pacific northwest and this
may bring slight cooling. The upper ridge will briefly rebuild
and strengthen on Sunday, with valley highs increasing into the
mid 90s. Another pacific trough is expected to bring a slight cool
down early next week. Ek

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. Ek

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
