heavy snowfall rates in the Sierra Nevada.

.DISCUSSION...
A strong cyclone continues to sit out over the Northeastern
Pacific with plenty of energy traveling onshore and into the
Pacific Northwest. This energy has resulted in significant
precipitation north of the district as some locations in
Northern California have received over 3 to 4 inches in the past
24 hours. So far, the district remains dry as the moisture and
dynamic lift target areas to our north. In addition to the
precipitation, strong winds have also developed to our north as
speeds have reached 40 to 50 mph. This far south of the jet max,
winds remain in the 5 to 15 mph range. These conditions are
expected to change once a piece of energy drops closer to
Central California and taps into the plume of subtropical
moisture (atmospheric river). Therefore, precipitation and
strong winds are expected as early as Friday afternoon with snow
falling at elevations above 7,000 feet.

High-Res short-range Ensemble Mean upper-air analysis keeps the
disturbance just north of the Central California Interior for
the next 24 to 36 hours. Therefore, confidence is high of the
dry forecast for today and Friday before the onset of
precipitation. While the onset of precipitation could start as
early as Noon on Friday, Probability of Measurable Precipitation
(PoP) doesnt reach 50 percent near Yosemite until closer to 4
PM PST. Afterward, more significant pieces of energy swing
through the area as the moisture plume spreads into Central
California. By 4 AM PST on Saturday, PoP reaches near 100
percent as ensemble place the area well within the Weak
Atmospheric River(AR) category and skirts the moderate AR
category. At these categories, ensemble precipitation analysis
has a probability of exceedance (PoE) of reaching 1 inch in 24
hours of 30-50 percent with spots hitting 60 percent. The target
area for heavy precipitation sits in the foothills from
Mariposa to Fresno County. An Excessive Rain Outlook has been
posted for these areas as flooding potential is possible with
the expected rain rate. The precipitation will also warrant a
Winter Storm Watch for the Sierra Nevada above 7,000 feet as 10
to 14 inches is expected by Saturday afternoon.

With little change in the weather pattern for the remainder of
the weekend and into early next week, precipitation will
continue to fall through at least Tuesday. Ensemble upper-air
analysis does not remove the upper level disturbance through the
area until Wednesday. Therefore, with several days of moisture
being pumped into the area, will maintain the Winter Storm Watch
through Tuesday. There is a bit of uncertainty on the passage of
the disturbance, yet, a high number of ensemble members do hint
toward having the disturbance exit by Wednesday. The end of the
week (day 7) hints toward a ridge developing. Yet, a percentage
of the ensemble members still hold on to a possible disturbance
over the West Coast. Will lean toward the drier pattern as fog
becomes the problem of the area as we reach next
Thursday/Friday.

as Probability of IFR conditions stands at 2-5 percent during
the next 24 hours.
