Synopsis
High pressure aloft will bring hot weather to the valleys and
deserts through tomorrow. A weak trough will bring cooling Thursday
and Friday along with a deeper marine layer. The weekend will be dry
with seasonal weather for late august.

Discussion For extreme southwestern california including orange...

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

Update...

excessive heat warning continues for the deserts from 11 am
through 8 pm Wednesday as temps soar into the 110s over the lower
deserts and 104-108 along and east of highway 248 in the high
desert (98-103 west). No significant changes were made to the
forecast this evening.

Previous discussion (issued at 115 pm pdt Tue aug 20 2019)...

today was quite a bit hotter than yesterday in the valleys as
high pressure aloft forced cooler marine air out of the western
valleys and replaced it with drier, hotter continental air.

The mountains and deserts were also quite a bit warmer. In
contrast, a 1,000 ft deep marine layer kept coastal temperatures
relatively unchanged from yesterday.

Here are the noon temperatures and dew points showing the 24-hour
changes in temperature and moisture from the coast to the desert.

Temp(f) dew point(f)
valleys:
chino 89 (+9) 30 (-30)
riverside 89 (+9) 48 (-12)
ontario 87 (+7) 48 (-11)
ramona 87 (+5) 55 (-2)
deserts:
thermal 107 (+7) 30 (-18)
palm springs 107 (+5) 28 (-9)
apple valley 94 (+4) 36 (-9)
borrego 107 (+4) 26 (-7)
mountains:
big bear 83 (+2) 19 (-6)
julian 85 (+2) 33 (-2)
coast:
san diego 75 (0) 64 (+4)
encinitas 74 (0) 66 (+1)
laguna beach 75 (-1) 66 (+2)
skies were clear this afternoon but marine layer clouds will
reform over the coastal waters and move into the coastal zones
later tonight. The marine layer may be 100-200 feet shallower and
may not reach as far into the san diego valleys as last night. Areas
of dense fog are again possible in some of the inland valleys
tomorrow morning.

The heat will peak Wednesday, and an excessive heat warning will
be in effect for the deserts through 8 pm. Highs will be from 114 to
118 in the lower deserts and from 104 to 108 in the high deserts
east of apple valley.

Thursday and Friday will be a little cooler as a weak trough of low
pressure moves inland across california. It will slowly deepen the
marine layer with greater night and morning low cloud coverage.

Long range: the long range ensemble GEFS and eps runs have trended a
little drier with the monsoonal moisture surging into the southwest
Saturday through Tuesday. The synoptic pattern shows a flat, east-
west oriented upper ridge extending from central california to
northern texas suppressing most of the moisture south of the border.

Temperatures will be near seasonal averages through the period.
