.METEOROLOGICAL CONDITIONS (MON AM - SUN AM)...

An upper low continues to exit the region into AZ this morning
leaving behind about 0.75-1" PW of moisture over much of srn CA. 12z
sounding out of San Diego recorded just over 1" PW at the airport
well above the 90th percentile for the date. Lingering moisture
along with some troughing has resulted in scattered showers over srn
CA. Current radar shows a number of echos over the San Bernadino
Mountains rotating in from the northeast across srn NV/se CA.
Observations already show about 0.50-1" of precip over that area
overnight. Increased the QPF there for the current period as showers
persist. The rest of today, the low will continue to exit to the
east though lingering moisture and troughing will generate
additional showers over srn/se CA and srn NV with possible
thunderstorms in the afternoon/evening. Much of NV and srn CA will
also remain below normal for afternoon high temperatures thanks to
the influence of the exiting low, anomalies about -5 to -15 deg F.

Behind the low, high pressure will build into the PacNW and nw CA
raising afternoon highs for much of nrn/central CA to 5 to 10 deg F
above normal while keeping conditions dry. Models then have another
smaller low dropping into ne NV from ID into early Tuesday heading
southwest through the state as it's caught up in the rotation of the
previous low then over NM. This second smaller low may also drop
some showers over NV and se CA Tuesday into Wednesday as it passes
through along with isolated thunderstorms. Dry conditions and above
normal temperatures for areas away from the low on Tuesday.
Wednesday, the ridge will shift further into CA/NV as its shoved our
way by a trough approaching the PacNW. High pressure will remain
overhead the rest of the week allowing dry conditions to persist and
temperatures to rise to above normal across the region. Expect
anomalies of +5 to +15 deg F with Friday/Saturday being the warmest
days. Some areas will approach +20 deg F above normal. Troughing
will reach the coast Saturday morning gradually moving overhead this
weekend. Not expecting any precip out of the trough thus far, but a
couple showers over the Smith Basin will be possible into Sunday
morning.

Most of the QPF for the period is expected today with precip
diminishing tomorrow. Low confidence in amounts as the precip will
largely be convective. Expect locally higher amounts than forecast
in any thunderstorms. Freezing levels 9.5-12.5 kft across CA through
Tuesday.
