Synopsis
A building ridge of high pressure over the great basin will bring
seasonally hot summer-like weather through the weekend. A weak surge
of monsoonal moisture early next week may trigger a few afternoon
thunderstorms over the mountains Monday.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

scattered small cumulus bubbled up over mountains this afternoon,
with the greatest coverage and vertical growth over southern san
diego county where brief light showers formed around 1 pm. It was
mostly clear elsewhere with a drier, more stable airmass moving in
from the northwest. Precipitable water values are about a half-inch
lower than yesterday. The pw on the 12z nkx sounding was 1.51" this
morning compared to 2.07" yesterday morning. A narrow layer of
midlevel moisture between 600-400 mb was enough to support the high-
based convection over southern san diego county this afternoon.

High pressure building over the great basin Friday will bring dry
and seasonally hot weather through the weekend with temperatures 2-4
degrees above average in most areas.

On Monday and Tuesday the ridge drifts east over utah and colorado
setting up weak southeasterly monsoon return flow across arizona and
into socal. This will not be a major moisture surge, but perhaps
enough for isolated afternoon convection over the mountains early
next week.

Wednesday through Friday: a weak trough just off the ca coast
battles for position with a massive upper ridge over the southern
plains. This pattern does not favor strong monsoonal flow into
southern california, so convection will be suppressed here for the
latter half of the week.

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.
