the possibility of isolated thunderstorms. Snow levels falling to
valley floors over northwest Humboldt county by late Thursday

LONG TERM...Thursday night through next Monday. High confidence
with models in good agreement on tight upper trough/closed low
Thursday night centered over central Nevada - western
Idaho...moving to Four Corners by Friday afternoon with northerly
flow over most of the Great Basin. Large ridge moves into the
Basin Saturday with drying/warming, but then flattens as another
system approaches from offshore.

However...confidence on the timing/position/strength/orientation
of this next system is low. by Sunday afternoon...the GFS has a
closed low over northern California and the EC has a flat ridge
over central Cali-eastern Oregon and it only gets worse through
MOnday. So model disagreements make a reasonable forecast in the
middle to long range....pointless is a strong word...extremely

For Thursday night into Friday, significant snows may fall on the
mountains, especially from around Jarbidge south to northeast Nye
County and eastward. biggest amounts may be from Great Basin NP
north to Spruce Range and then Pequops. Travel may be an issue and
advisories may be warranted for snow and blowing snow.

AVIATION...Generally VFR through the period but with mountain
obscurations over higher ridge at sites and en route, through mid
day Tuesday. Decreasing clouds and rising ceilings through Tuesday
afternoon. Winds decrease overnight. Snow showers or rain/snow
combined through Monday evening then diminishing. Cigs/visibility may
drop to MVFR at times through Monday evening. KELY AMD NOT SKED
ufn due to missing visibility.

HYDROLOGY...Rivers are still up in parts of central Nevada and
most of northern Nevada. Any rain just melts snow pack, and snow
adds to the pack. Expecting rains/snows this week over most of the
region, through about Thursday night, then a break into next
weekend. However, snow amounts could easily total a foot on many
ranges and even a few inches on valley floors. Should be a wet,
moisture packed spring-like snow, as well.

Expecting flood warnings and advisories to continue for next
several day, and for the Humboldt River, weeks, possibly longer
for the lower Humboldt River.


Wind Advisory until 11 PM PDT this evening for Northeastern Nye
County-Northwestern Nye County.
