Areas affected...Portions of LA
Concerning...Tornado Watch 75...
Valid 080000Z - 080100Z
The severe weather threat for Tornado Watch 75 continues.
SUMMARY...An isolated severe threat continues across southern
portions of Tornado Watch 75 and vicinity.
DISCUSSION...Convection has continued struggling to intensify across
much of Tornado Watch 75 early this evening. A feed of greater
low-level moisture is present across LA, where generally mid 60s
surface dewpoints are present along/south of ongoing convection. One
cell in northern LA has recently developed low/mid-level rotation,
and VWPs from area radars show sufficiently veering/strengthening
wind profile with height to support continued updraft rotation. A
tornado remains possible in the short term with any storms that
remain at least semi discrete. Isolated strong/gusty winds also
appear possible. At this point, the need for a downstream watch
remains uncertain, but trends are being closely monitored.
