...HIGH PRESSURE CONTINUES TO DOMINATE THROUGH THE WEEKEND...
...INCREASING MOISTURE BRINGS SHOWERS/T-STORMS MAINLY SOUTH/EAST...

.METEOROLOGICAL CONDITIONS (THU AM - WED AM)...

High pressure resides over the 4-Corners with the axis of this
feature stretching northwest toward the west coast of the Pacific
Northwest and BC...while general troffing is situated across the
northeast Pacific this morning. This feature will continue to be the
dominant player for conditions across the region through the weekend
as 500-mb heights increase to near 6000-meters at the center of this
high pressure cell...peaking either Friday or Saturday. Temperatures
will be somewhere from plus 5- to plus 15-degF over seasonal
normals. For next week...the area of high pressure will finally
begin to weaken and shift a bit downstream toward the southern
Plains states...while general troffing forms along or just off the
west coast.

Also...given the flow around this area of high pressure...it is
looking like enough moisture associated with the monsoon will creep
northward across portions of CA and NV...bringing an increase in the
chance for showers/t-storms beginning today but looking better for
this weekend into Monday and Tuesday. Areas with the best
opportunity to see precip develop will be the central/southern
Sierra and points east across NV and south over southeast CA.

Freezing levels are currently running from 16000- to 17500-feet and
will fluctuate through the weekend. By next week...there will
finally be some decrease in these down to 15000- to 16500-feet by
Tuesday.
