From GSP
By Wednesday, models agree on a
shortwave trough spurring coastal
cyclogenesis over the remnant cold frontal band leftover from
Tuesday`s system. Aloft, the polar and subtropical jets align
with the midlevel forcing and could result in
rapid deepening
of this system. As a result, a renewed possibility for
active
weather on Thursday, as the surface low drags another cold
front
through our
CWA in the afternoon.
QPF is much more impressive
for this system, and with both the
GFS and the
ECMWF demonstrating
moderate
SBCAPE and an 850mb
jet producing impressive deep layer
shear, both Wednesday night and Thursday afternoon could bring
another opportunity for thunderstorms. It`s much too early to
dig into either the intensity or timing at this point, but by
Friday evening the last of the frontal precip should have abated,
giving way to dry northeasterly
flow.
