Area Forecast Discussion
National Weather Service Sacramento CA
833 AM PDT MON APR 25 2016

.SHORT TERM DISCUSSION...

.Synopsis...
Breezy today, with another system mid week. Mid week system looks
like a lower impact storm with valley showers and mountain pass snow.

&&

.Discussion...
No changes to forecast. Still a little instability around for
areas south of Highway 50 in Sierra, this covered well in current
forecast. Next system moves down from the north and west. Location
of the upper low will be very important. Further west along the
coast will result in more precipitation for our forecast area and
further east will be drier and windier. Right now, GFS taking a
wetter approach and NAM a drier approach. Bottom line, either
path would result in a not so impactful weather system except for
isolated heavier rain with showers, with other impact snow at pass
levels. 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. 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 a few showers across the
Sierra, south of US 50, on Saturday, but moisture is limited so
have kept dry forecast at the moment. This system will serve to
strengthen northerly flow though, so locally breezy winds not out
of the question for the weekend.
