Synopsis
Gusty offshore winds with support for continued warming west of
the mountains can be expected through Saturday. A transition to
onshore flow will bring cooler conditions to the coast and some
valleys with warming across interior areas as high pressure builds
overhead through at least early next week.

Short term (tdy-mon)
the north wind event has now transitioned to a NE wind event. The
inside slider trajectory was a little more eastward than fcst and
this reduced the amount of upper level support so the winds will
be a little weaker than advertised. There will still be a good
amount of northeasterly advisory wind gusts near the la/vta county
line. The upper support vanishes and the gradients relax early in
the afternoon and this will end the winds. In fact most of the
coastal areas will see a decent sea breeze during the mid and late
afternoon. The other big story today will be the MAX temps. Look
for 90s in the la/ventura valleys and near 90 for inland coastal
zones. The record MAX temps are pretty high so there will likely
be no records set today. The best bets for records will ucla (91)
and sba (85).

Offshore flow will continue Sunday but will only be half a strong
as it is now and by afternoon it will actually reverse and become
onshore. There will be no upper support so while there will be
some northeast canyon winds in the morning they will not reach
advisory levels. The lessening offshore flow will result in good
cooling for the coastal areas and some cooling in the vly. The
increasing hgts will actually allow for warming across the
interior.

Not much excitement for Monday. Upper level pattern is about the
same. There is some debate if an eddy will spin up or not. Right
now the consensus is that it will not or if it does it will be too
weak to create stratus. This could easily not be correct so will
have to keen an eye on it and see if the morning forecast needs a
little stratus added to it for la county. More cooling for the
coasts and vlys as the onshore push continues but the interior
will remain rather warm.

Long term (tue-fri)
the ec and the GFS agree well on the forecast through Wednesday.

Both forecast a weak east pac ridge to set up just off the state.

Both forecast week offshore flow from the north and weak onshore
flow to the east. There will likely be some night through morning
low clouds and fog across the la coast. MAX temps will continue
above normal ESP from the vlys and inland.

The ec breaks the ridge down quicker than the GFS starting
Thursday. It also forecasts much stronger onshore flow. If it
turns out to be correct MAX temps will be much cooler than the gfs
or the forecast. Will have to keep an eye on this and see which
mdl trends to the other.
