Looking at the NWS, they have this to say about LA:
.LONG TERM...(
SAT-TUE)
The
trough will deepen Saturday which will continue the cooling
trend and increase the marine lyr depth and coverage. Could even
see some morning drizzle Saturday. With heights lowering through
the day and increasing onshore
flow it`s possible many areas will
stay
mostly cloudy through the afternoon, especially
coast/valleys. Aside from the possible drizzle it should stay dry
most of Saturday as the upper low and better
moisture doesn`t
arrive until late Saturday night into Sunday. At that point models
are in reasonably good agreement considering we`re dealing with a
spring time
cutoff low. Both the
GFS and
ECMWF place the low
center somewhere between Bakersfield and Oxnard Sunday morning,
then slowly wobble it southeast to the southern Colorado River
Valley Tuesday morning. The best chances for precip in our area
appear to be Sunday afternoon and evening with pretty cold air
aloft, -27c at 500
mb Sunday afternoon. Although model
stability
parameters were marginal at best those kind of temps aloft this
time of year are certainly enough to help spawn some
thunderstorms so went ahead and added those for Sunday. Still,
this is one of those scenarios where some places could get little
to no rain while others could see some heavy downpours, small
hail, and
thunder/
lightning. Snow levels pretty low as well,
around 5000 feet so there could be a couple inches of accumulation
at higher elevations.
Both models shift a lot of the
moisture and colder air south and
east Monday and Tuesday, though not far enough to remove precip
chances from the forecast. There really isn`t much of an
upstream
kicker to motivate the upper low to move too far east so at this
point it`s best to keep some
pops in the forecast through early
next week at least.
