valid 241200z - 251200z
...no severe thunderstorm areas forecast...
...summary...
isolated thunderstorms will be possible on tuesday from far
southeast georgia to the florida peninsula. no severe threat is
forecast.
...synopsis...
a mid/upper shortwave trough and strong surface low are forecast to
move across parts of british columbia on tuesday, as a trailing cold
front moves across the pacific northwest. weak convection may
develop along and in the wake of this cold front, but inland
buoyancy appears too meager for more than very isolated thunderstorm
potential.
farther south and east, an upper ridge is forecast to amplify
somewhat over the southwest on tuesday, with a west-northwesterly
flow regime expected to persist downstream across much of the
central/eastern conus. an embedded mid/upper-level shortwave trough
will move across the lower ms valley and southeast. a cold front
that moves into north fl late d2/monday is forecast to slow down and
weaken on tuesday.
modest buoyancy may develop near the remnant front, and isolated
storm development will be possible across the fl peninsula and
adjacent southeast ga, both diurnally, and potentially in response
to the approaching shortwave trough late in the period. weak
deep-layer shear is expected to limit storm organization. some weak
destabilization will also be possible near the remnant front across
the central gulf coast and lower ms valley. it appears the shortwave
trough will be displaced north of any appreciable destabilization
along the western portion of the remnant front, but weak convection
cannot be ruled out from la/ms to the fl panhandle.
