...PRECIPITATION POSSIBLE OVER NORTH SUNDAY INTO TUESDAY...
.24 HOUR PRECIPITATION TOTALS (ENDING DEC 2 AT 400 AM PST)...
Scattered showers with a couple hundredths of an inch of precip were
observed across northeast NV with system dropping south across the
area. Otherwise...high pressure building off the west coast brought
dry conditions to the rest of the region.
.METEOROLOGICAL CONDITIONS (SHORT TERM: FRI AM - MON AM)...
Ridge over the Eastern Pacific and into Northern CA with a trough
over the great Basin and stretching into Southern CA and Mexico
today. The trough shifts to the east with a ridge of high pressure
dominating the region on Saturday. This will bring N-NE winds and a
dry forecast except for a few light showers possible in the Upper
Klamath Basin this afternoon into early Saturday. An upper level
trough moves into the Pacific NW on Sunday bringing precipitation to
the Upper Klamath Basin, Smith River Basin and possibly the Eel
River Basin and Shasta Drainage. Precipitation moves into northern
Nevada Sunday night. Models farther north so trimmed some of the
southern edge of precipitation. Freezing levels around 6000-7000ft
Sunday morning dropping down to around 3000-4000 ft by Monday
.METEOROLOGICAL CONDITIONS (LONG TERM: MON AM - THU AM)...
An initial cold front will be traversing the northern portion of the
region with the best opportunity for light precip across northeast
NV early on Monday. Then...models bring in the s/wv trof from
northwest to southeast across the CA/OR border area on its way
toward the Great Basin. The trend of the models has been a bit
shallower and east with the system...limiting precip across the
area. Best opportunity for precip will be later Monday into early
Tuesday across areas near the CA/OR border and northern NV as the
s/wv trof shifts overhead.
Day 6 was kept dry and followed closer to the similar 02/00Z EC and
GEM. The GFS is weaker with the upr ridge on Wednesday and brings
precip to the north coast quicker.
Rivers across the area will slowly recede towards baseflow over the
next few days. All forecast points are expected to remain well below
