Synopsis
Strengthening high pressure will bring a warming trend inland
through Wednesday. Very hot inland weather Wednesday will
diminish slightly toward the coming weekend. Coastal clouds will
be on the decrease each night and morning, then increase later
this week.

Discussion For extreme southwestern california including orange...

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

low clouds took some time to clear from orange county this morning.

A wisp of high clouds has accented our skies today, but we're all
looking at plenty of blue up there. Look for low clouds to have
nearly as much coverage as they did this morning, but after Monday
morning clouds probably won't make it into the inland empire for
a while. That's because high pressure aloft will build over the
southwest and onshore flow will decrease the next few days.

Coastal clouds will remain coastal each night and morning, and may
even be reduced to patchy coverage Wednesday and Thursday. We're
looking at a decent warming trend this week. Wednesday will be the
hottest day, with temperatures 5-10 degrees above average. That
means around 115 in the lower deserts and 100 to 105 in the inland
empire and high desert. The latest guidance has backed off the
intensity of the heat. A fly or two gets in the soup, weakening
the high pressure slightly. Friday and Saturday there is some
increase in monsoon moisture. A weaker high and increased moisture
will both help the temperatures taper off some as we head into
next weekend. Will the moisture be enough for thunderstorms in the
mountains and deserts? So far it doesn't have a strong enough
case to warrant including those chances in the forecast yet. High
pressure seems to build again next weekend, keeping temperatures
slightly above average.
