Area Forecast Discussion
National Weather Service Hanford CA
133 PM PDT Mon Mar 20 2023

.SYNOPSIS...
Brief calm weather conditions will prevail for the rest of the
afternoon, before the next event begins. This event will start to
come into our CWA tonight, with the majority of the precipitation
falling Tuesday through Tuesday night. The system will be petering
out Wednesday afternoon and will have moved out completely by
Thursday morning. Calm weather will prevail for our area through
to Sunday night, with another system coming in Monday morning.

&&

.DISCUSSION...
The calm weather pattern will prevail until tomorrow morning when
an upper level trough will start to push in another storm system
to our CWA. This will bring rainfall to the San Joaquin Valley and
the Sierra foothills and snow showers to the Sierra Nevada above
5000ft. There will also be a chance for thunderstorms in the
valley tomorrow as the cold front associated with the system
moves past. High winds will impact I-5 pass and the mountains
surrounding it by early tomorrow morning and start to effect the
rest of the CWA by the late morning tomorrow. Thunderstorms will
be most likely Tuesday night.

Probabilities for most of our valley locations show 50-75% chance
of receiving 0.5 inches of rain on Tuesday, with Fresno showing a
85% chance of 0.5 inched of rain. Probabilities for some of our
foothills locations show 30-40% chance of 2 inches of rain or more
on Tuesday, and for some of our mountain locations show 45-70%
chance of more than a foot of snow on Tuesday.

After this system moves out of our area, calm weather will prevail
once again and run through Sunday, before another system will come
through the area on Monday. This system appears lighter than this
upcoming one, however this may change as more time passes and
confidence increases.

&&

.AVIATION...
VFR conditions will prevail for rest of the day. Some areas of
MVFR and IFR conditions are possible over the Sierra Nevada due to
the clouds and showers tonight and tomorrow afternoon.
