Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
245 AM PDT Sat Apr 22 2017

.SYNOPSIS...
Dry and warm conditions through Monday. Breezy at times. Chance
of showers in the Sierra North of Kings Canyon Monday afternoon
through Tuesday afternoon. Seasonal temperatures with windy
conditions possible on Wednesday.

&&

.DISCUSSION...
Upper ridge across the region will provide above normal
temperatures today. A trough of low pressure will cross the region
on Sunday with breezy conditions and more seasonal temperatures.
We are not expecting any precip with the system, as the best
dynamics and deep moisture remain well to the north.

NW quasi-zonal flow sets up across the region with another trough
expected to cross the area Monday and Tuesday. Unsettled weather
is expected across the Sierra with afternoon showers. Moisture is
also limited, however there is enough dynamics to create enough
lift to wring out a few showers Monday afternoon and evening
continuing off and on into Wednesday evening. The GFS is keeping
a large scale upper low over the Intermountain West which could
keep things unsettled into Wednesday as weak upper level
disturbances move through the Sierra.

NW flow aloft will keep us dry and seasonal through the remainder
of the week and into early next weekend. EPAC ridge to our west
and deep trough to our east keeps us in a very stable pattern for
the next several days.
