Areas affected...Northern/Central LA

Concerning...Severe Thunderstorm Watch 390...

Valid 261215Z - 261345Z

The severe weather threat for Severe Thunderstorm Watch 390
continues.

SUMMARY...The threat for damaging gusts and isolated hail continues
across northern and central LA.

DISCUSSION...Recent radar imagery has shown an increase in forward
propagation with the westernmost portion of the convective line
extending across northern LA. Storm motion in this part of the line
is now estimated around 45 kt. These storms continue to reside
within the theta-e gradient between the mid to upper 70s dewpoints
across west-central/central LA and the upper 60s dewpoints farther
north. Outflow continues to push just ahead of these storms,
although the recent southward surge has brought the leading edge of
the higher reflectivity close to this boundary. Given these trends,
the threat for damaging gusts has locally increased, particularly in
the SHV vicinity. Additionally, the threat for damaging gusts will
likely persist into more of central LA, and the watch has been
extended in area to address that potential.
