area forecast discussion

257 pm pdt Tue sep 25 2018
Warm weather will continue through Thursday. Cooler with a slight
chance of showers for the weekend into early next week.
An upper ridge over the northeast pacific has begun to build into
california today, as a shortwave trough over the northern rockies
shifts eastward. The mfr-rdd pressure gradient has been steadily
decreasing over the last 24 hours, and locally gusty north winds
have diminished as a result. Clear skies prevail across the
region, and although some marine stratus has spread along the
coast, we're not seeing any cooling effects across the interior.
Temperatures this afternoon will be in the 90s across the valley.
Some locally breezy conditions may continue tonight over the
mountains, but should be weaker than the last few nights.
Wednesday will likely be the warmest day this week across the
region, with 90s to near 100 degrees across the valley. Expect
temperatures in the 70s to 90s over the mountains.
Temperatures will cool a couple of degrees Thursday. More
noticeable cooling is expected starting Friday as a closed upper
low approaches the coast. Forecast temperatures on Friday will be
close to normal, with upper 80s to lower 90s across the valley.
.Extended discussion (Saturday through Tuesday)
pacific low portion of the offshore rex block is forecast to push
onto the north coast by Saturday afternoon. This will bring
significantly cooler temperatures with daytime highs dropping to
between 5 and 10 degrees below normal. GFS and ECMWF both
indicating some precipitation associated with this low over the
coast range and northern mountains Saturday afternoon and evening.
This low opens and shifts to the northeast on Sunday but a few|
lingering showers may still be possible over the shasta county
mountains. Models diverge going in to early next week with GFS and
ecmwf coming in with two different but interesting outcomes. Ecmwf
solution brings a fairly strong for the season pacific low and
frontal system into northern california on Monday. Precipitation
amounts with this scenario would be fairly significant for early
october and likely a fire season ending type of event. GFS has a
significantly different outcome taking the pacific low to the
southeast keeping it off the coast. In this scenario, moisture
from a tropical depression now south of baja is forecast to be
pulled northward into southern california on Monday bringing a
significant amount of precipitation to the southern half of the
state. For the most part this model solution would leave northern
california dry although the southern most CWA could receive some
light precipitation. The end of the extended period, next Tuesday
looks dry and a little warmer at this time but model confidence
is low with such a large variation in model solutions.
Vfr conditions the next 24 hours. Northwest to northeast winds
10-15 knots gusts to 25 knots sacramento northward and over the
sierra. Otherwise winds generally below 10 knots.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
