Synopsis
Upper level low pressure will weaken across the area today with
decreasing showers and slow warming. Warming will continue on
Friday with a slight chance of afternoon showers near the
mountains. A slight chance of showers will return for Saturday
afternoon and evening. Another low pressure system from the north
will bring cooling and greater chances for showers on Sunday with
warming and decreasing shower chances on memorial day. Drier with
a slow warming trend for Tuesday through Thursday with weaker low
pressure over the southwest states.

Discussion For extreme southwestern california including
orange... San diego... Western riverside and southwestern san
bernardino counties...

Short term (today through Saturday)
The center of upper level over northwest arizona early this
morning will move into utah today with upper level low pressure
across southern california weakening through Friday.

Early this morning, radars show a few isolated showers over
coastal and valley areas of san diego county and an area of light
showers moving southeastward across mountain and adjacent desert
portions of southwestern san bernardino county.

Showers are expected to increase near the mountains and inland
valleys this morning with more widely scattered coverage toward
the coast. The showers are then expected to decrease during the
afternoon and early evening.

Friday should be drier for most areas, but there could be a few
light showers during the afternoon along sea breeze convergence
boundaries in the mountains and adjacent high desert areas. Slow
warming will begin today with a little greater warming on Friday.

Onshore flow will begin to strengthen on Saturday with slow
cooling for the coast and valleys and continued slow warming for
the deserts.

A weak trough of low pressure moving southeastward through nevada
and california could bring a few showers to the mountains and high
desert areas on Saturday afternoon and evening.

Long term (Sunday through Wednesday)
Another low pressure system from the north will bring cooling and
greater chances for showers on Sunday with drying and warming on
memorial day as the trough of low pressure moves to the east and
weakens across the area. The ECMWF and its ensemble mean is slower
to weaken low pressure over the southwest states for the middle of
next week which would result in a slower warming trend for
southern california.

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.
