.DISCUSSION...
Central California will see the continuation of warm and dry
conditions during the early part of this week. The associated
ridge of high pressure that governing our weather will shift
east in the next 24 hours as temperatures remain in steady state
going into Monday. Therefore, high temperatures will peak Today
with the area along Interstate-5 having 15-35 percent chance of
reaching 90 degrees (with the higher probabilities are in the
Taft area). Will see minimal cooling on Monday through Wednesday
ahead of the next disturbance expected over California.

Later in the period, a disturbance will enter the region around
the mid-week period with onset timing of between Wednesday
Night and Thursday morning. Due to uncertain nature of dealing
with a Closed Low, will maintain a large timing spread until the
storm reaches the short-term. For now, will see more
significant cooling and an uptick in winds over the favored
locations of the Sierra Nevada Crest and the Tehachapi
Range/Mojave Desert as the disturbance nears Central California
on Thursday. As for precipitation, initial chances over the
Central Sierra Nevada will be in the 10-20 percent range for a
tenth of an inch by early Thursday.

By Friday, while ensemble uncertainty in the storms placement
is high, probability of receiving a tenth of an inch (0.10)
jumps to 40-70 percent across the Sierra and between 20-40
percent across the San Joaquin Valley. In addition, probability
of receiving a Quarter of an inch (0.25) across the High Sierra
during a 24 hour period remains around 30-50 percent. With snow
levels remaining above 7,000 feet, the mentioned percentage
ranges will place snow accumulation in the 2 to 4 inch category
with a 10 percent chance of 5-7 inches over the Sierra Nevada
Crest where orographics may enhance precipitation values near
the upper range. Uncertainty in the timing of the storms
passage will necessitate a mention of precipitation until early
next Saturday. Furthermore, will expect Thunderstorm activity
for the latter part of the week as ensembles place a 5-15
percent chance of thunderstorms across Central California
north of Kern County  on Thursday. Thunderstorm probability
rise to 15-25 percent on Friday (best chances) and drop back to
5-15 percent on Saturday.

Latest CPC outlooks suggest that above average temperatures
will continue trending toward the 40-50 percent chance of being
likely leaning above seasonal normals. On the other-hand,
precipitation in the 6-10 day period are leaning/likely above
normal with the odds trending more toward leaning (33-40
percent) of being above normal for the 8-14 day periods.
