Synopsis
A cold, unstable trough of low pressure will bring showers,
thunderstorms and high elevation mountain snow through this evening.

A few showers will linger into Thursday, followed by dry weather
Friday and Saturday. Another storm from the north will bring another
round of showers Sunday into Monday.

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

showers and thunderstorms erupted over the northern sections of
inland empire near the foothills of the san bernardino mountains
this afternoon. A heavy downpour north of rancho cucamonga dropped
0.55" at deer creek dam, and small hail was reported in yucaipa
shortly before noon, and in beaumont at 12:40 pm. Moreno valley
spotters reported heavy rain and small hail.

The href, and to some degree the hrrr, show this convection moving
south-southwest deeper into the inland empire and into parts of
orange county through late afternoon. The atmosphere will become
more unstable under the warm may Sun with CAPE increasing to 300-500
j kg. The elsinore convergence zone could be the focus for stronger
cells. Heavy downpours will result in brief flooding in areas of
poor drainage.

The center of the 500 mb cold core will be directly overhead through
early evening and showers and isolated t-storms will be possible
just about anywhere. So far the radar returns have skirted around
the sbd mountains, and we haven't had any snow reports yet, but as
the trough moves south the snow chances will increase. Snow levels
are around 6,000 feet.

The trough axis passes through this evening with scattered showers
tonight into Thursday in the cold, moist, and unstable air behind
the trough. Thursday will be another cool day with below average
temps in the valley, mountain and desert zones. Friday and Saturday
will be a little warmer, but it will still be below average.

On Sunday and Monday another deep trough forms over the west.

Embedded shortwaves rotating around the closed low will bring
chances for more showers Sunday and Monday. The stagnant trough
pattern over the west means temperatures will remain below average
through early next week.

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.
