Area Forecast Discussion
National Weather Service Sacramento CA
1000 PM PDT MON APR 25 2016

.Synopsis...
Another quick moving spring weather system Wednesday. Main impacts
look to be snow (not too heavy) above 6000 feet with showers and
maybe a thunderstorm in the valley.

&&

.Discussion...
Ridging builds in behind the closed low over the Great Basin on Tue
for a milder day with much less wind. Although max temps will be
slightly warmer than today over most areas...it will be a few
degrees below normal on Tue. There will be a brief break...as the
next system is forecast to move into the area on Wed.  JHM

Still a little uncertainity as to exactly where it will track with
the GFS still a bit further west resulting in a bit more
precipitation for the valley. Tend to think the NAM solution makes a
bit more sense with less valley rain. Either way, valley
precipitation should be mostly showers so splash and dash type of
precipitation.

Have added thunderstorms to the forecast as hard to not get
thunder with these convective systems. Rasch

.EXTENDED DISCUSSION (Friday THROUGH Monday)

High pressure will build into the area on Friday and remain in control
of local area through early next week, bringing dry weather and
warming temperatures. Lingering moisture over the Sierra may bring
isolated mountain showers Friday afternoon. High temperatures
will near the 90 degree mark in the Valley by Sunday. Models
showing a weak system dropping SE into the Great Basin with
enhanced north winds possible.
