...LIGHT SHOWERS AND COOL NEXT FEW DAYS...

.24 HOUR PRECIPITATION TOTALS (ENDING FEB 24 AT 400 AM PST)...

Scattered light precip over the upper Klamath River basin down
through northeast CA and down the crest of the Sierra brought
amounts generally from a few hundredths of an inch up to 0.10-inch.
A few wetter locations saw amounts nearing 0.25-inch.

Over northeast NV...amounts were generally from 0.10-inch or less as
well.


.METEOROLOGICAL CONDITIONS (SHORT TERM: FRI AM - MON AM)...

Expect increasing showers along the north coast today ahead of an
upper low dropping south off the Pac NW coast.  Showers are expected
to spread inland and south through Sun as the upper low/trough
slowly drops south off the coast and eventually inland across s-
cntrl CA.  Showers should mainly be confined to coastal and Sierra
locations as well as the upper Klamath basin and nrn/cntrl NV.
Another trough moving across the north is expected to spread more
showers across the region.  Amounts should again remain light with
limited moisture over the area.  Sierra freezing levels should range
from around 3000-5000 ft through the period.


.METEOROLOGICAL CONDITIONS (LONG TERM: MON AM - THU AM)...

The area will begin the period under north to northwesterly flow
aloft that will bring the opportunity for light scattered precip as
a s/wv trof moves through the region on Monday into early Tuesday.
This will transition to the eastern Pacific upr ridge nudging toward
the coast later in the period for dry and warming conditions.


.HYDROLOGICAL CONDITIONS...

Most rivers in the CNRFC forecast area are esxpected to continue to
recede or fluctuate near present levels for the next several days.
The exceptions are the Sacramento, San Joaquin, and Humboldt rivers
where runoff from precipitation and/or water from reservoir releases
earlier this week are still moving downstream.  Portion of these
rivers may continue to rise for a few more days.
