410 am pst Sat feb 24 2018

Synopsis
Below normal temperatures will continue. Snow showers possible
over the mountains today with additional systems next week
bringing more widespread precipitation.

Discussion
Next system now moving south from vancouver island and puget sound
will not be impactful for norcal today as it will be a weak,
rather benign (nuisance) wx system bringing some light showers to
mainly the mountains. Some high clouds are already moving
southward across interior norcal, but these are not having much
effect on temperatures as current readings are colder through much
of the valley with only the thermal belts seeing milder
temperatures.

Dry weather on Sun will be followed by another wx system on mon.

This system will also be similar to its predecessors, cold with
relatively low qpf, and high snow ratios. (favoring the nbm
snow ratios during these colder goa systems.) however, the
central valley should see more rainfall than yesterday's system.

Nam bufkit forecasts around a quarter inch for sac, and this may
be the last shot of rain this month. Dts rainfall for the month
remains at zero through today, although sac exec had .01" yesterday.

Here is the list for the driest febs for dts:
1) 0.04 in 1899
2) 0.16 in 1913
3) 0.19 in 1995
4) 0.21 in 1953
5) 0.26 in 1997 & 2013
spc plume forecasts show about 10 inches of snow for the mean at
blu for the Mon system, and our forecast is trending toward that
average, and about 15-20:1 snow ratios for the sierra. (the
"normal" slr is about 9:1.) a wide swath of 8-12 inches of snow
is forecast with isolated amounts greater than a foot near the
sierra crest.

The wr us west coast ar landfall tool (probability of ivt) continues
to show a lack of moisture, albeit it is not as "bone dry" for the
next 16 days as yesterday's models. However, there remains a lack of
significant ars. What moisture there is will be spilling over the pac
ridge and basically eroding as it hits the pac NW and spreads inland
into our cwa. (one could make a weak argument that the Mon system may
have a little more moisture than what was forecast yesterday.)
another break Tuesday with breezy north winds ahead of more active
weather likely to return for early march.

.Extended discussion (Wednesday through Saturday)
a period of dry weather is expected for the beginning of the
forecast period except for shower activity over the mountains.

Then, a deepening trough and its associated frontal boundary will
impact the area late Wednesday into the early weekend. However,
forecast models are still struggling with the progression of this
system and precipitation amounts. Regardless, this system will
likely bring widespread precipitation across interior norcal.

Early QPF estimates suggest 0.25-1" across the valley and 1-2.5"
over the mountains through early Friday, though amounts will
likely change this far out. In addition, periods of heavy snow
could cause travel difficulties over the sierra. Breezy to gusty
winds are expected as the system moves through, especially over
the sierra. Temperatures will remain below seasonal normals.

Aviation
Vfr conditions next 24 hours except local MVFR conditions over
the mountains due to scattered snow showers after 15z Saturday.

Winds less than 12 kts at TAF sites except for gusts up to 20 kts
from krbl northward after 18z Saturday.

Sto watches warnings advisories None.
