Synopsis
High pressure aloft along the west coast will bring unseasonably
warm weather this week. High temperatures will be 15 to 25 degrees
above average Wednesday and Thursday. Cooling will gradually spread
inland Friday through next Sunday as high pressure aloft weakens and
onshore flow returns.

Discussion For extreme southwestern california including orange...

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

satellite imagery at 8 pm pst... Showed cirrus filaments drifting se
over socal this evening, otherwise the skies were clear. The
temperature column on the 00z miramar sounding indicated modest
warming and quite dry below 28k ft. The sfc pressure gradient
remained offshore at 7 mbs SW nv to ksan and about neutral to the
lower deserts. Winds were light.

It will be another very chilly night in wind-sheltered valleys, but
indications are it won't be as cold as last night. No changes to the
forecast this evening.

From previous discussion...

this morning started out cool in the wind sheltered valleys where
temperatures fell into the mid 30s at riverside and san pasqual
valley. In contrast, temperatures were some 20 degrees higher in the
windy areas like rancho cucamonga and fallbrook where the early
morning temperatures were 58f. The coldest air settled over the san
bernardino mountains and high deserts. Morning lows were in the
upper 20s and low 30s at victorville, hesperia and phelan, with the
coldest spots in the mountains at baldwin lake (13f) and the big
bear airport (14f).

The weather will turn warmer through Wednesday as 500 mb heights
steadily increase as a high amplitude upper ridge builds over the
southwest. This strong ridge aloft combined with weak offshore low
level flow will bring greatest warming Tuesday through Thursday with
highs in the 90s in the lower deserts and the valleys. Coastal zone
highs will be in the 80s, and mountain highs will be in the 60s and
70s. Both Wednesday and thanksgiving day will be exceptionally warm
days with record highs likely.

Friday through Sunday... The ridge aloft weakens and onshore flow
will return to southern california. Cooling will spread inland but
temperatures will still be a little above average through next
Sunday.

Aviation
200430z... Coast valleys... A shallow marine layer will create a small
possibility of fog along the coast tonight. Confidence is moderate
to high that coastal aerodromes will remainVFR. Otherwise, high
clouds and p6sm vis through Monday evening.

Mountains deserts... P6sm vis through Monday evening, with high
clouds at times.

Marine
Slight chance for patchy dense fog with visibility one mile or less
late tonight into Monday morning. Otherwise, no hazardous marine
conditions are expected through Friday.

Fire weather
There was still some very dry air in place today over eastern and
northern portions of the forecast area from the valleys to the
deserts where minimum rh fell into the single digits. A slight
recovery is expected over the mts through Tuesday. But drier
conditions will develop this week over the valleys and coastal
foothills as temperatures rise and offshore flow strengthens
slightly.

By Wednesday into thanksgiving day, daytime high temperatures are
forecast to rise well into the 80s and lower 90s west of the mts as
east to northeast winds increase. The combination of very dry
conditions, near record high temperatures, and areas of easterly
winds 15 to 25 mph with gusts to 35 mph will create elevated fire
weather conditions, mainly along the offshore wind-prone areas of
the coastal foothills.

Conditions will slowly improve into the weekend as the offshore
weakens and the high pressure ridge aloft, subsides.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.
