thanks for tuning in to this video weather briefing
which we take a look at the state of the climate in the dry weather
that we have been occurring and expected to continue
this video was about five minutes long this is the warning coordination
meteorologists here at the national weather service
here's a snapshot of what we expect for the upcoming weekend and then we're
going to take a look at the spring to summer outlook in the later slides
in general the dry weather is expected to continue
now there is a storm system that that
has been gradually weakening as we get closer to the event on sunday and monday
but our precipitation timing remains for sunday into monday
all areas but only light rainfall except
dry conditions for the lower desserts
there will be some wind in passes and our desert slopes with few areas getting
gusts over forty miles per hour
for the precipitation mainly drizzle
from our deep marine layer on sunday
then some light showers
for sunday night and monday morning as the system passes through
west of the mountain spine mostly
and a few hundredths of an inch of rainfall for the coastal areas the mesas in the
valleys
some places even getting no precipitation
up to a quarter-inch in the San Bernardino County mountains
the snow levels in general will be high as the storm goes to our north
perhaps dropping as low as sixty five hundred feet early monday morning
confidence they'll remains low to moderate for the timing of the track of
the storm
is cut off from the main jet stream and will show that on the slides
generally minor impact from this storm system
here's a look at the precipitation forecast
all the way through monday april first
this is a forecast for california
really light precipitation amounts less than a quarter of an inch
what do we mean by storm system that is cut off from the main jet stream
this image here depicts how the storm
will evolve across the eastern pacific the main jetstream going
well to the north into western canada
part of the jet stream going across at the central pacific
with not much flow to move it along just enough from the southerly branch
that'll bring it across
central california late Sunday into Monday
how will it look on sunday md
into monday
march thirty first
the storm track is shown here the storm system will weekend as we mentioned
become a little bit broader and less compact
while it is expected to drift across central portions of california just to our north
how we doing so far well so far since october?
we've had several storm systems and they have it amounted to a
whole lot
for the exception of maybe san diego county
where
san diego's about three inches below normal where should be at this time
in orange county almost seven inches same as riverside over seven inches
below where it should be about this time when compared to the thirty-year normal
generally across the area
most locations are about forty to sixty percent of normal
a little bit less in the desert
where even palm springs three inches below normal is quite significant for
region that doesn't receive annually a lot of precipitation
alright let's take a look at the sea surface temperatures across the pacific ocean
anomaly
will focus on the spring to summer outlook
currently right now there's a large area of cooler than normal sea surface
temperatures from the california coast
all the way
down into parts of the central pacific
now we're not going to look at any
el nino or la nina, since sea surface temperatures in the central
equatorial pacific or about neutral right now and expected to remain there
the cooler than normal sea surface temperatures could be a player for our
spring months ahead for the immediate coast
the outlook for the spring april to june
basically for southern california
we're looking at equal probability
for being above or below normal
for april through june
so in other words not much of the signal that'll keep us
away from a general normal conditions with temperature and precipitation as we
go into the spring and early summer
you can see
there's increasing confidence though over much of the country
for warmer than normal conditions setting up early this year
take a look at the
forecast for july through september
you can see the above normal conditions basically right over the four corners
region of the West expanding into our death is a southern california
and also areas will be a battle
with the sea surface temperatures depending if they warm up a little bit to "normal" values for the summer month
so generally
near normal conditions on the coast
and above normal conditions
maybe a few more heat waves of larger magnitude
for inland valleys
and certainly across our desert
not much signal for precipiation
generally a little bit below normal
and perhaps that's an indication of a little bit weaker than normal monsoon
season we go from july through september
