...LINGERING SHOWERS AND POSSIBLE T-STORMS TODAY...
...MOSTLY DRY CONDITIONS FOR THURS/FRI BEFORE SHOWERS RETURN FOR THE
WEEKEND...

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

Yesterday's low has opened into a broad upper trough that is
currently making its way through the PacNW and nrn CA/NV. Radar
imagery shows an area of showers near the base of the trough from SF
through the I-80 corridor heading into the nrn Sierra. This area
will be the main focus of precip the rest of today while scattered
showers and isolated thunderstorms remain possible elsewhere as well
across nrn/cntrl CA/NV as the trough progresses further inland.
Conditions expected to dry out for Thursday/Friday in between
systems. Troughing will develop offshore on Friday before moving
into central CA over the weekend. This system is expected to
generate scattered showers over much of the region throughout the
weekend. Another trough then looks to drop in from the PacNW on
Monday bringing additional shower activity to parts of CA/NV as yet
another trough approaches from the southwest. So far, none of these
systems look particularly intense precip wise. Bottom line, an
active pattern continues throughout the forecast period as a series
of troughs move in. Longer range outlooks from CPC continue to
predict above normal precipitation into the first week of May.

The forecast mainly made use of WPC guidance, but blended in the 12z
HRRR for the rest of today to capture some of the convective
activity. Expecting another 0.10-0.75" the rest of today from the
Bay Area through I-80 to the nrn/central Sierra with locally higher
amounts under thunderstorms. For the weekend into early next week,
expecting 0.10-0.75" across the Sierra, Shasta, and
central/southern/eastern NV. Maybe a few hundredths of an inch or so
for parts of coastal srn CA.

Freezing levels starting today at 5-7 kft north of I-80 rising the
rest of today and tonight up to 6-9 kft. Later Thursday, levels back
up to above 10 kft across CA gradually lowering over the weekend
down to 5-8 kft state wide by early Sunday. The presence of
troughing should keep levels from rising more than another 1 kft or
so away from srn CA.
