Synopsis High pressure will provide dry conditions into at
least early next week. A warming trend will bring temperatures
to well above normal by Sunday then little changes through the
middle of next week.

Discussion Positively tilted upper ridge extends from central
california to the northern rockies. The ridge will provide dry
conditions and a warming trend this weekend. A weak S WV trough
will move over the pac NW Sunday afternoon, but will have little
impact for cencal. High temperatures are forecast to climb into
the upper 80s across the san joaquin valley & kern county desert
by Sunday, with a few areas likely topping 90 degrees.

A deep upper low is progged to drop down over the epac early next
week with amplified ridging over the far western conus. The models
have been struggling to agree with the evolution of this low. The
latest runs favor keeping it well offshore through midweek then
lifting nne towards the pac NW coast late in the week. This will
keep temperatures 10-15 degrees above normal through midweek then
a modest cooling trend to follow. Some slight chance pops remain
over the sierra nevada around yosemite np from Wednesday through
the end of the week as there could be a little afternoon evening
convection.

the next 24 hours.

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.
