.UPDATE...Updated air quality issues section.


.SYNOPSIS...Temperatures will trend a little lower through
Tuesday. Windy conditions will develop through and below the
mountain passes today through Tuesday. Otherwise dry weather
will continue over the district for the next several days.


.DISCUSSION...Satellite imagery shows the next trough moving
across Oregon and Washington with a thin line of moisture over
Northern California. Thus far under some slightly lower heights
temperatures are trending lower however thus far with no
appreciable marine layer along the shore, temperature trends are
flat through Pacheco Pass. After the trough axis moves through
this evening, some additional synoptic cooling will take place,
but this will not be a major cooling at all.

High resolution models due increase winds through the usual places
like Pacheco Pass, Cottonwood Pass and of course the Tehachapi
Pass and adjacent desert locations. Not really seeing the threat
of widespread strong winds through any of these locations and will
opt to not issue any advisories at this time.

Over the next several days, models keep a weak trough of low
pressure over the region with high pressure remaining over the 4
Corners Region and transitory low pressure systems moving along
the Canadian border. This leaves Central California high and dry
with no threat of any thunderstorms in the Sierra or any threat of
monsoonal moisture either through the weekend.

Next week, models continue to try and push the Desert Southwest
ridge to the west and bring a surge of moisture into Southeast
California on southeast monsoon winds aloft. Will have to wait and
see if this is finally the first monsoon push or not as this year
has seen the Pacific westerlies dominate.


VFR conditions can be expected across the central California
interior during the next 24 hours.





The level of certainty for days 1 and 2 is high.
The level of certainty for days 3 through 7 is high.

Certainty levels include low...medium...and high. Please visit for additional information
an/or to provide feedback.
