area forecast discussion
national weather service sacramento ca
325 am pdt Sun sep 24 2017

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

Discussion
Northern california under upper northerly flow between building
high pressure over the eastern pacific and a closed low over the
southern great basin. Combination of surface high pressure over
the pacific northwest and upper north flow will bring continued
breezy north winds. These winds and warming airmass will keep
daytime rh values on the low side with only poor to moderate rh
recovery at night. Wind and rh will bring periods of critical fire
weather through early next week. Upper ridge will edge slowly
inland over the next couple of days bringing a few to several
degrees of airmass warming each day. Upper ridge axis is forecast
to center over the west coast by Wednesday which should bring
lighter pressure gradients and lighter winds with maximum
temperatures leveling off at a few degrees above normal.

.Extended discussion (Thursday through Sunday)
eastern pacific ridging will remain over the area dry and warm through
the week. Daytime highs will likely remain 5-10 degrees above
normal, with low 90s across the valley, delta and into the lower
foothills. By the end of the forecast period, the ridge will
slowly be displaced as a trough approaches the pacific northwest.

A portion of that upper energy could extend into our area and keep
temperatures from trending upward and potentially bring slight
cooling. Overall, little change in weather is expected. Ek

Aviation
Vfr conditions expected for valley TAF sites for the next 24
hours. Northerly gusts up to 20-25 kts possible in the northern
sacramento valley today 18-02z.

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.
