National Weather Service San Joaquin Valley - Hanford CA
405 PM PDT Fri Mar 23 2018

There is a chance for some mainly light showers this weekend with
temperatures a little below normal. Dry conditions and a warming
trend will develop Tuesday through the end of next week.


A welcome day of dry weather today after the very impressive
atmospheric river event of the last few days. A 3-day storm total
rainfall of 2.26" fell at the Fresno Air Terminal (KFAT),
bringing it up to 66% of normal for the water year, which began
last Oct. 1. Bakersfield Meadows Field (KBFL) received 1.32",
bringing it up to 71% of normal. There were numerous reports of
3-6" of rainfall in the Sierra Nevada and foothills, and a few
automated gauges measured as much as 8-9".

An upper low spinning off the Pacific Northwest coast will swing
in a s/wv trough on Saturday for another chance of precipitation.
But this will be a much drier system with mainly light showers
across central California. The best chances will develop Saturday
afternoon through the evening. QPF gives only a few hundredths to
a tenth of an inch for the San Joaquin Valley, mainly from Fresno
County northward. Of note, we only need 0.01" more rain at KFAT
to tie for the 10th wettest March on record, which is 4.19". The
Sierra around Yosemite NP has around 0.5" QPF with decreasing
amounts to the south. Snow levels during the bulk of the precip
will be around 4-5K feet. Snow amounts should generally be 2-4"
with local amounts around 6". A few lingering showers will remain
possible through Sunday as snow levels are expected to lower near
2500-3500 feet, but accumulations should be very light. Another
weak disturbance diving down on Monday may bring a few more very
light showers over the Sierra on Monday. Dry weather is forecast
from Tuesday through the end of next week as high pressure over
the eastern Pacific nudges inland.

Temperatures will remain a few degrees below normal through Monday
then trend warmer beginning Tuesday. Highs in the SJ Valley are
forecast to climb into the lower to mid 70s by Wednesday, then in
the upper 70s and some lower 80s by Friday.


Localized terrain obscurations and low ceilings in the Sierra
foothills and Kern County mountains through 18z Saturday. A few
showers will move south into central California after 18Z Saturday.
Otherwise, VFR conditions will prevail throughout the central
California interior during the next 24 hours.





The level of certainty for days 1 and 2 is high.
