.SYNOPSIS...
The summer doldrums will continue through next week with warm and 
humid weather. A weak monsoonal flow will maintain a chance for 
mainly afternoon and evening thunderstorms over the mountains and 
deserts. The greatest chances for thunderstorms will be Friday and 
Saturday, and again around the middle of next week. Patchy night and 
morning low clouds and fog will spread inland each night, and then 
burn back offshore each morning, along with periods of higher clouds 
at times.

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

Evening Update:

No updated were needed this evening. Very limited convection 
occurred today within our area, there were just a couple of cells in 
the Santa Rosa Mountains, just west of the Coachella Valley. 
Convection was probably limited due to subsidence along the eastern 
periphery of the East Pac High Pressure ridge. There may be a little 
better chance for convection Friday afternoon, but still only 
isolated coverage is expected for Friday afternoon and early 
evening. Nonetheless conditions will remain very warm and humid 
across SoCal, and any storms that develop could contain brief heavy 
downpours and slow storm motion. 

Remainder of Previous Discussion (issued at 148 PM PDT):

High pressure aloft will remain in control over the SW through the 
weekend and next week. Shifting and repositioning of the axis of 
high pressure will determine the direction of our weak flow aloft, 
and ultimately, moisture availability. Through the coming weekend, 
we will remain on the edge of some very deep tropical moisture that 
is smothering NW MX and the Lower Colorado River Valley of SE CA. 
Any convective systems that develop there, could influence our 
weather, due to outflow and convective debris. Forecasting those 
details beyond anything more than 12-24 hours will be difficult to 
impossible, so expect forecast adjustments. 

Based on the various ensemble projections, more show greater 
precipitable water values at various places in the CWA Friday into 
Saturday, with drier solutions predominating early next week, 
followed by another increase in moisture mid next week. Following 
the PW trends gives us some variation in the POPS, but nothing 
concrete. Bottom line...We remain in a weak monsoon pattern well 
into next week, which favors afternoon, mountain convection, and to 
a lesser extent, the deserts. As of now, we don't see a good chance 
for any of this activity to make it to the coast, but it wouldn't be 
surprising if something didn't develop next week for a few hours.

Except for periods of extensive cloudiness from the east, and/or 
precipitation, daytime temperatures will be close to mid summer 
averages.

.AVIATION... 
190400Z...Coast/Valleys...Areas of low clouds will continue 
developing along the immediate coast through 08Z Fri and spread up 
to 20 miles inland by 13Z Fri. Bases will be 1000-1200 ft MSL with 
tops to 1400 ft MSL. Local vis 3-5 miles will occur in the coastal 
valleys 10Z-15Z. Most areas will clear 15Z-17Z with mostly SCT 
clouds at/above 15000 ft MSL Fri afternoon. Areas of stratus will 
develop near the immediate coast again Fri evening.

Mountains/Deserts...SCT-occasional BKN clouds at/above 15000 ft MSL 
will continue through Fri evening with mostly unrestricted vis. 
There is a slight chance of TSRA Fri afternoon/early evening with 
bases 8000-10000 ft MSL and tops to 40000 ft MSL along with strong 
up/downdrafts and local gusty surface winds.
