.SHORT TERM...
(Tonight through Sunday Night)
Issued at 1219 PM CDT Sat Jun 14 2025

Weak troughing aloft will keep us in a somewhat unsettled pattern
through the weekend with a fairly typical diurnal ebb and flow to
convective activity. With surface high pressure centered over the
western Atlantic, low level winds will maintain an onshore
component and continue to bring Gulf moisture into the local
area.

Ample moisture and an atmospheric profile conducive for convection
will only be waiting on a trigger - namely in the form of daytime
heating. With that said, expect isolated to scattered showers and
storms to begin popping up after sunrise, with a maximum in
coverage and intensity during the afternoon hours, and dissipation
around or shortly after sunset.

Afternoon temperatures should top out around or just over 90
degrees today and tomorrow, which is near normal for this time of
year. However, with PW running 110-120% of normal, the extra
moisture in the air will inhibit radiational cooling causing
overnight lows to remain warmer than normal, only dropping into
the mid 70s most locations, with upper 70s or even lower 80s along
the immediate SE LA coast.

Current forecast indicates maximum afternoon heat index values
peaking in the 100-105 degree range which is shy of the heat
advisory criteria, but there could be a few spots that hit 108
temporarily - especially in the wake of any isolated showers if
there isn`t sufficient outflow to cool the temperature.

.LONG TERM...
(Monday through Friday)
Issued at 1219 PM CDT Sat Jun 14 2025

With the weak troughing/break between ridges remaining in place to
start the week, Monday through Wednesday will generally be
repeats of the weekend, with relatively high rain chances and near
to warmer than normal temperatures.

The upper pattern will flatten out by midweek, with weak ridging
building in to end the week. This should result in a return to
more typical summertime POPs by Thursday/Friday, which is lower
than what the NBM is indicating at the present time. Have made
some adjustments to trend a bit lower than the NBM POPs Thurs/Fri
given the recent high bias of the NBM in the extended and the fact
that with upper ridging building in, we really should see a
decrease in convective coverage.

.AVIATION...
(06Z TAFS)
Issued at 1112 PM CDT Sat Jun 14 2025

VFR to MVFR conditions across the area due to CIGs. This
situation should remain for the rest of the night. Exception to
this is low stratus and perhaps some patchy fog at MCB of which
the low stratus will be the driver for reducing conditions to IFR.
A general repeat of yesterday`s weather is expected this afternoon
and succeeding TAF packages will provide more detail on exact
timing and locations of afternoon convective impacts through TEMPO
and PROB30.

.MARINE...
Issued at 1219 PM CDT Sat Jun 14 2025

High pressure centered east of the local area will keep onshore
flow in place through the period, generally 15 kts or lighter.
Expect to see daily showers and storms, with higher winds and seas
in the vicinity of this activity.
