...SERIES OF SYSTEMS IMPACTING THE REGION INTO THE MIDDLE OF NEXT
WEEK...

.METEOROLOGICAL CONDITIONS (FRI PM - THU AM)...

The s/wv trof axis is approaching the north coast this
afternoon...while the sfc cold front plows inland at a good clip.
Radar imagery shows the heaviest precip aligned ahead of the frontal
boundary from the northern Sierra back across the southern
Sacramento and northern San Joaquin Valleys before reaching the
coast near the Monterey Bay area. Precip gauges since 13/18Z
indicate some two hour totals close to or even exceeding 1.00-inch
over the Marin Headlands...southern Napa County and the Santa Cruz
Mountains. Minor adjustments upwards were made over the entire SF
Bay Area to account for current radar trends and gauge reports with
increases from 0.10- to 0.25-inch. Elsewhere...the current period
shows a decrease along the north coast around 0.10- to 0.25-inch
with the cold front making quicker progress inland.

This system will shift inland this evening and overnight with the
best precip moving over north-central NV and the central/southern
Sierra back toward the Point Conception area before tapering off
across eastern NV and southern CA tonight. Tomorrow is mainly a
break day with a transitory upr ridge sliding across the area before
the next system approaches the coast on Sunday and lingering through
Monday. This s/wv trof will dig offshore and then shift inland
bringing the best precip to the northern half of the
region...diminishing across southern CA.

Still plenty of questions for the Tuesday into Wednesday system as
models are struggling with both the timing and trajectory of the
s/wv trof approaching the coast. Few changes were made this far out
in the forecast period...as to not jump around too much.
