Area Forecast Discussion...UPDATED
National Weather Service Hanford CA
356 PM PST Fri Dec 11 2020

.UPDATE...Updated Air Quality Section.

&&

.SYNOPSIS...
A cold front will move through the region today, bringing gusty 
wind through the wind-prone areas of Central California during the
day. A couple more disturbances are likely to pass through 
northern California, bringing threat of light rain and high 
elevation snow in the Sierra. 

&&

.DISCUSSION...
A few locations in Kern County have continued to be breezy, though
should see those too diminish over the next hour or so. In the
Southern Sierra Nevada along and east of the Kern River RH values
have dropped into the single digits. These areas will remain dry
throughout the day today with better recoveries expected tonight.

A shortwave trough is digging across the Western CONUS today, with
an inside slider track. This has brought some light showers to
NorCal. This area of precipitation will spread southward
throughout the day today, with Yosemite seeing precip by this
afternoon/early evening. 

By morning most locations should have seen some precip. Sorry some
locations will be rain shadowed. The current thinking is that will
be the southeastern San Joaquin Valley, including western Kern. 

A second impulse will makes its way through on Sunday which will
bring a second round of precipitation Sunday into Monday morning. 

Integrate water vapor transport analysis shows a high probability
that a decent plume of moisture will slide in from the
northwest overnight tonight. The directionality of the IVT points
to an upward trend in precipitation relative to the past few 
days for Saturday. While not expecting drought break rainfall, it
is definitely a welcome sight to see and does increase the
potential for good wetting rains.

Early next week, however, things do look like they will trended
back to the dry side, though there is potential for a late week
storm. The East Pacific Ridge is finally weakened enough for some
winter storms to slide into the area.
