Synopsis
An upper trough in place this weekend will be replaced by ridging
aloft building in from the east next week. The result will be
increasing heat inland during the early to middle part of next
week. Another period of excessive heat is possible across the
deserts Tuesday through Thursday. Monsoonal moisture may begin to
move into southern california from the southeast late next week,
tempering temperatures, but increasing humidity. A few
thunderstorms could be possible over the mountains and perhaps the
deserts by next weekend.

Discussion For extreme southwestern california including orange...

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

Highlights
* increasing temperatures early-mid next week
* excessive heat watch for the deserts Tuesday-Thursday
* monsoonal moisture return by late next week is a possibility
southern california is being influenced by the southern extent of
a longwave upper trough over the u.S. West coast. This feature
has brought a slightly cooler airmass into the region, tempering
inland temperatures compared to what they were a couple days ago.

However, the intense heat will be back for the desert regions as
an upper ridge builds in from the east during the early to middle
part of next week.

For this weekend, temps stay in check as we are influenced by
stronger onshore wind flow. Onshore pressure gradients MAX out on
Sunday. We will continue to see a few hour period of gusty winds
along the deserts slopes as well as through and below passes onto
especially the high desert floor with gusts of 30-40 mph forecast.

Marine layer low cloudiness will spread further inland and could
take some time to clear some of the beaches today and tomorrow,
though sunshine is favored for the afternoon. Can't rule out
clouds sticking to a few beach locales though.

Heat will be the story next week with the upper ridge taking hold
from the east. H85 temps rise to about 30c over the deserts with
peak heat looking to occur Wednesday. Have issued an excessive
heat watch for the Tuesday-Thursday period for both the high and
lower deserts with peak highs looking to be 105+ for the high
desert and 112-118 for the lower desert. 120 degrees is even a
possibility again at isolated locales. The inland valleys will get
hot as well, though likely not to excessive levels.

The upper ridge lifts north late next week. This could open the
door to monsoonal moisture entering into socal, tempering
temperatures, but increasing humidity, along with perhaps a return
to potential thunderstorms for the mountains and deserts by next
weekend. Low confidence though this far out in time.
