.SYNOPSIS...03/130 PM.

Isolated showers and thunderstorms are possible today as an upper
low moves into the area. Otherwise, a June gloom pattern will
prevail through this week with a slow warming trend.

&&

.SHORT TERM (TDY-FRI)...03/145 PM.

An upper low has destabilized the air mass today creating
isolated showers and thunderstorms. This morning the focus was
across SLO County, but as the low moved south through the day the
focus shifted to mostly LA and Ventura Counties with a solid line
of storms between Catalina and San Clemente Islands. Rainfall has
so far been scant but as CAPE`s and updraft rates increase
through the afternoon with surface heating, precip intensities
will increase with higher chances for rain at the surface,
especially in the mountains. Models have been highlighting the
eastern LA mountains this afternoon as the most likely areas of
convection and possible heavy rain and that appears to be proving
accurate as radars are showing a line of storms moving east to
west from the San Bernardino mountains to the eastern San
Gabriels. Can`t rule out some isolated flooding issues in the
mountains along with small hail and gusty winds and isolated
showers across the lower elevations through this evening.

Wednesday through Friday are expected to be much quieter weather
days with the current 2500 ft marine layer continuing. Stratus is
expected to clear most of the valleys but will struggle closer to
the coast. Highs are expected to be 3-6 degrees below normal
Wednesday, then warming a degree or two Thu and Fri.

.LONG TERM (SAT-TUE)...03/201 PM.

Most of the ensemble solutions are on board with the warming
trend through the coming weekend with warmer valley highs in the
mid or possibly upper 90s. But much cooler at the coast with a
moderate to strong onshore flow. Confidence isn`t great beyond the
weekend as model solutions start to show quite a bit of spread but
at this point not seeing anything through the middle of next week
that`s too far from normal.
