Clear and dry conditions across central ca this afternoon. Water
vapor images show wind flow aloft turning west due to an upper
trough moving through north california. The airmass moving into
central ca appears very dry at mid and upper levels. Temperatures
running much cooler today due to a stronger onshore flow and
synoptic cooling with the trough. Expect an elevated risk for

Models in fair agreement in maintaining a westerly flow aloft
through mid week. A couple of additional disturbances will move
through the pacific northwest suppressing a ridge south towards
the baja peninsula. This will likely keep a cool maritime flow
into the interior of california into mid week.
Models prog the upper ridge rebuilding northward over the east
pacific for the latter part of the week. This should usher in
dry and warm trend for the second half of the work week.
The warmup may be mitigated during the weekend with the|
extended models indicating a weak upper trough moving through the

chances for precipitation throughout the period as moisture is
The lower temperatures may slow the runoff of melting snow from
the sierra and help to alleviate some of the flooding concerns
downstream. However, high water level continue in the kings river
with large outflow from pine flat dam and a flood warning remains
in effect for portions of northern kings, northwest tulare and
central fresno counties. Waterways will continue to run cold,
deep, fast and dangerous as they continue to be fed by melting
Vfr conditions will prevail across the central ca interior during
the next 24 hours.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
