area forecast discussion
national weather service sacramento ca
248 am pst Thu jan 24 2019

Synopsis
Dry weather with locally breezy northerly winds expected through
the end of next week. Daytime high temperatures a few degrees
above normal.

Discussion
High amplitude upper level ridge over the eastern pacific and west
coast will keep the forecast dry and dominate the weather pattern
through the short term period. Northerly surface gradient
combined with northerly flow around the upper ridge bringing light
northerly winds to the northern sacramento valley this morning
and this is keeping fog from forming in this area. Farther south,
lighter surface gradient and therefore lighter winds southern
sacramento and northern san joaquin valleys allowing for some
areas of fog there. Overall airmass warms today under building
ridge and early morning temperatures a little above 24 hours ago.

Today's highs will climb a few degrees over yesterday or about 5
to 10 degrees above normal for this time of year.

Upper ridge axis pushes towards to coast on Friday bringing a
little more warming and lighter north winds. Drying airmass should
keep valley fog at a minimum. Upper ridge axis continues to move
inland over the weekend centering over the west coast on Saturday.

This will bring the warmest temperatures of the week over the
weekend with daytime highs expected to reach from 10 to 15
degrees above normal.

.Extended discussion (Monday through Thursday)
mid-level ridging over california continues Monday through Thursday
keeping conditions dry. An enhanced pressure gradient across the
sierra may lead to some gusty north and east winds Monday into
Tuesday. Next week high temperatures remain in the 60s in the valley
and the upper 40s and 50s at higher elevations. There may be a
chance of the ridge breaking down by next weekend, but model
disagreement is still high at this point so confidence is low for
any precipitation chances.

Aviation
MostlyVFR conditions over the next 24 hours, except for MVFR
conditions due to patchy fog from smf southward after 12z
Thursday. Ksck kmod may reach lifr briefly due to fog.

Sto watches warnings advisories
None.

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.
