.SYNOPSIS...02/209 AM.

June gloom will be in full force this week with night through
morning low clouds fog occuring every day. Most max temps will
remain below normal through the week. A small warming trend will
develop at the end of the week.

&&

.SHORT TERM (TDY-WED)...02/253 AM.

The marine layer is not behaving this morning and most of LA
county remains cloud free. The latest satellite trends do show a
decent mass of stratus moving up through Orange County and this
should bring low clouds to the LA county coast and portions of the
San Gabriel Vly towards dawn. The San Fernando and Santa Clarita
Vlys should remain clear. Low clouds do, however, cover most of
the csts/vlys of SLO/SBA/VTA counties. Moderate onshore flow this
afternoon will make for slow clearing and possibly no clearing for
some west facing beaches. Max temps are forecast to fall 3 to 6
locally 8 degrees today, but this may be too much due to the
weaker than fcst marine layer intrusion.

Tuesday will be a interesting day esp for June. Another upper low
will spin down the coast tonight. At first it will lift and deepen
the marine layer. Look for low clouds to cover all of the coasts
and vlys and should xtnd to the cstl slopes. The rapid lift will
likely produce areas of drizzle in the morning. In the afternoon
stronger onshore flow will likely keep the low clouds over the
csts for the day. The instability and lift of the low will combine
with some moisture and will produce a slight chc of TSTMs over the
LA and VTA mtns in the afternoon and evening. Max temps will not
change much and will remain below normals. In addition, there
will be gusty onshore winds across the interior, with gusts mostly
in the 25 to 40 mph range, except locally up to 45 mph in the
Antelope Valley foothills.

The upper low will linger in the evening and bring a chc of
showers to the LA mtns and the Antelope Vly.

The low will exit the area early Wednesday. Wrap around moisture
and weak dynamics from the low will bring a slight chc of some
showers to eastern LA county in the morning. June Gloom continues
with morning low clouds across the csts/vly with slow clearing in
the morning and no clearing for a few west facing beaches. Another
round of gusty west winds is also on tap for the Antelope Vly. Max
temps will not change too much again and will remain blo normal.

.LONG TERM (THU-SUN)...02/304 AM.

It looks like a fairly persistent pattern for the rest of the
week and weekend. Broad large scale pos tilt troffing will cover
NV/CA Thu and Fri. The trof will weaken over the weekend as high
pressure moves in. Hgts will rise from about 580 dam Thu/Fri to
586 dam by Sunday. Mdt to stg onshore flow will continue Thu/Fri
and then weaken over the weekend.

Skies will be mostly clear save for the night through morning low
clouds across the csts and most of the vlys. The weaker onshore
flow and higher hgts will likely reduce the amount of low clouds
over the weekend esp for the vlys.

Max temps should slowly rise, esp Sat/Sun, as the hgts rise. By
Sunday most max temps should be above normal.
