Area Forecast Discussion...UPDATED
National Weather Service Hanford CA
324 PM PST Sat Feb 6 2021

.UPDATE...Updated Air Quality Section.

&&

.SYNOPSIS...Dry conditions with above average temperatures are
expected across the region through Monday. A weak system will
move through the region on Tuesday, and will bring light showers
to the higher elevation of the Sierra National Forest and Yosemite
areas. A return to a wetter, more active pattern is expected
toward the end of next week. 

&&

.DISCUSSION...Patchy morning fog has given way to a sunny warm 
afternoon. With a strong ridge of high pressure still in control 
over the eastern Pacific, today's temperatures across the district
will end up between 2 to 6 degrees above average for the date. 
For tonight into Sunday morning, portions of the valley will once 
again experience patchy dense fog. But, the fog will not be 
widespread, and will affect similar areas as Saturday morning. 

For Sunday, the aforementioned ridge will remain firmly in control
over the region. Afternoon high temperatures will once again be 
anywhere between 4 to 8 degrees above average, with mostly sunny 
skies. The high pressure ridge will begin to flatten to a zonal 
flow on Monday. Minor synoptic cooling along with increasing cloud
cover will lead to a decrease in the afternoon high temperatures.
However, temperatures will still remain near average for a 
majority of the district.

A weak, fairly unimpressive shortwave trough will drop through 
the central California interior on Tuesday. This will bring 
considerable cloudiness, but near-normal high temperatures. 
Latest guidance brings some very light snow showers, with little 
to no accumulation, to the higher elevations of the Sierra 
National Forest and Yosemite areas. This trough quickly ejects 
into the inter-mountain west on Wednesday as weak northwesterly 
flow moves back into the area. For Thursday through the end of 
next weekend, models as well as blended model guidance are still 
indicating a return to a wetter, more active pattern.

.AVIATION...Areas of IFR with local LIFR in fog are likely in the

conditions will prevail over the central California interior 
during the next 24 hours.
